[[File:Ad_-_Prevue_Grid.png|200px|thumb|right|Prevue Grid displaying an ad]]
'''Prevue Grid''', also known as '''blue grid''' and '''a2-blue''', was the final iteration of the Prevue software, used from 1993-2000. Like [[Prevue List]] and [[EPG Sr.]], Prevue Grid ran on the Amiga platform. There were many differences between these three Amiga-based software editions, however. Whereas [[Prevue List]] displayed a list of what was currently on on each channel, then what would be on in the future at different times, the Prevue Grid showed what was on each channel currently and in the future at the same time.

The Prevue Grid software had 3 different names over the course of its usage: Prevue Guide, Prevue Channel, and lastly, for just a few months, TV Guide Channel. Only one version of the Prevue Grid software (9.04), which is thought to be the final version, is currently on the internet. The disk contains listings from December 13th 1999, meaning that if an Amiga running the software is set to that date, listings are shown. Because the software internally counts days from January 1, the year is unimportant, but if a leap year is used, make sure to select December 12th instead. Under emulation, the most reliable way to set the Amiga date is to change it on the host computer, as WinUAE will always reset the clock to that of the host upon a reboot.

==Specifications==

This version of the Prevue Grid software requires the following minimum specifications:

*2.04 or 2.05 Kickstart ROM
*Chip RAM: 1.0MB
*Fast RAM: 1.0MB
*CPU: 68000
*Chipset: ECS

When running it under emulation, it's a good idea to make the window size 760x480 - this causes the image to be perfectly centered in the window. To create screenshots with the proper aspect (to simulate what you'd get from a video capture on a real Amiga), crop the 760x480 screenshots down to 740x480, then resize it using a bilinear algorithm to 640x480.

[[File:Guru_Error.jpg|200px|thumb|right|Common Amiga Guru Meditation error produced by Prevue Grid]]
This particular Guru Meditation error is caused by insufficient chip RAM. Insufficient fast RAM will not cause a Guru Meditation, but it will cause the software to throw an ER011 error and freeze up. It is '''not''' compatible with Kickstart 3.1 - the software will boot, but there are major graphical problems. It is compatible with the AGA chipset, but requires softkicking with a 2.x ROM in order to avoid the glitches.

==Operation==

The software has several different modes, which are accessible through the system's menu. To access the menu, press ESC while in listings mode. The keyboard commands that are available depend on which mode the software is in. While in Diagnostic mode, any keypress that is not recognized by the software as a valid command will dump back out to the main menu.

===Listings mode===
'''Ctrl-B''' - this shows '''SCRLSPD = ''x'' ''' to appear on the top half, showing the current scroll speed.

'''Ctrl-C''' - this causes the software to redraw the screen. This is not done cleanly - there are glitches while it happens, but it redraws the screen freshly.

'''Ctrl-D''' - this causes the scroll speed to decrease by one (making it faster). This also allows access to the "disallowed" speeds 0 and 1.

'''Ctrl-E''' - this causes the scroll speed to increase by one (making it slower). If you press '''Ctrl-B''' beforehand, the on-screen speed will change as well.

'''Ctrl-G''' - this causes the software to draw a calibration grid, useful for adjusting an attached monitor to ensure that none of the image is being cut off at the edges. If done in Listings mode, it can cause display corruption which will be repaired once the listings have a chance to cycle around. This works in Diagnostic mode too, but causes the software to erroneously begin using the listings font to draw the diagnostic menu, instead of the ad-editing font, causing text to be positioned incorrectly.

'''Ctrl-S''' - this causes the listings to switch into single-step mode. Each keypress of Ctrl-S from this point will make the listings scroll one step, then stop.

'''Ctrl-U''' - once the current "block" fully scrolls on the screen, the clock will stop and no more blocks will scroll onto the screen, parking the floppy drive and enabling a safe reboot or shutdown.

'''C''' - this causes the current color palette to be displayed on top of the listings.

'''E''' - save error log to DF0:err.log.

'''F''' - this causes text to appear on the top half denoting some internal settings. It is currently unknown how to modify these settings.

'''G''' - this triggers graphical ad mode, which currently goes through all the banners present on the disk.

'''H''' - shows CLU (~channel) information on the top half of the screen (use ad mode (shift-A) first to see it clearly). Each press steps through the list. CTRL-H steps backwards through the list.

'''J''' - shows PI (programme information) on the top half of the screen, according to which ever CLU was just selected by pressing H. Each press steps through the list. CTRL-J steps backwards through the list.

'''K''' - tries to load clock.cmd from DF0: which fails given the disk we have (although there is a ClockCmd=1 shown on the diagnostics when pressing F)

'''L''' - Left Video - draws a black overlay over the right half of the screen, allowing only the left half to be seen (in emulation, however, this seems to shift the grid position)

'''N''' - this causes the top half to switch to color 0, enabling display of external video via the genlock.

'''P''' - reload gradient.ini from DF0: (use unknown)

'''R''' - Right Video - draws a black overlay over the left half of the screen, allowing only the right half to be seen (in emulation, however, this seems to shift the grid position)

'''S''' - this causes the listings scroll to continue.

'''Y''' - cycles the colour indexes of the 32 colour palette used on the top half. The graphics ("logos") on the disk we currently have are all in 320x240 32 colours. Adverts are actually shown on a 32 colour screen, although only 8 colors are accesible via the editor. Press it 32 times to return to the "normal" palette.

'''/''' - this cycles through 9 "Viewmode" tests on the top half. They cycle through different resolutions and different positions (left half, right half, full screen).

'''Shift-A''' - this causes text ads to appear on the top half, and will cycle through all ads that are marked "active" through the menu.

'''Shift-D''' - this causes the software to reload its current listings from its cache stored on disk.

'''Shift-K''' - creates (in the background) a list of the logo files within DF0:logos and (seemingly) updates DF0:logo.lst

'''Shift-N''' - this causes some diagnostic text stating "BitPlane1 = 40468" to appear over the listings. Numbers seen have been 40468, 3C3A8 and 38568. Unsure as to the reason this exists.

'''Shift-S''' - this causes the listings scroll to stop.

'''Shift-T''' - this seems to have the same effect as Shift-A at the moment. It is unknown what difference there is to Shift-A.

===Diagnostic mode===
'''Shift-1''' - Changes TEXT between L, S, N, and R. L most likely means Local, as setting TEXT to L is the only way to access the Edit Ads and Edit Attributes main menu items. Unsure about the others but it's possible that either S (serial) or R (RS-232) refers to feeding ads in over serial. S may also refer to Satellite (though operationally this would be the same as Serial).

'''Shift-2''' - Changes VIN between L, I, Z, N, Y, and y. Perhaps VIN refers to Video INput? Conjecture at this point without a manual or some good old RE'ing.

'''Shift-3''' - Changes LINE between 6, 5, 4, and 3. This controls the maximum number of text lines per ad.

'''Shift-4''' - Changes GRPH between L, R, S, N, and Y. Once again, it is unknown what this means, perhaps it allows the PowerPacked IFF files to come in from another source, allowing graphic updates without exposing the UI to the viewer?

'''Shift-9''' - Causes a brief pop-up above the visual indicators for these settings that says Start TAPE Video.

'''Shift-0''' - Causes a brief pop-up in the same spot as Shift-9 that says stop.

'''1''' - Causes '''KHHR''' to change to '''Silence''', but this does not persist when you re-enter the diagnostic screen.

'''2''' - Causes '''Left''' to appear in this spot.

'''3''' - Causes '''Right''' to appear in this spot. Looks like it might be used to test the audio source that goes to air?

'''4''' - Causes '''Background''' to appear in this spot.

'''5''' - Causes '''Ext. Video Only''' to appear haphazardly over the "Press any key to continue." prompt.

'''6''' - Causes '''Computer Only''' to appear there.

'''7''' - Causes '''Overlay Ext. Video''' to appear there.

'''8''' - Causes '''Negative Video''' to appear there.

'''9''' - Causes '''Video Switch Open''' to appear where the earlier Start and Stop message did.

'''Ctrl-A''' - Shows all free RAM types.

'''Ctrl-C''' - Shows free chip RAM.

'''Ctrl-F''' - Shows free fast RAM.

'''Ctrl-M''' - Shows largest contiguous block of RAM.

'''C''' - Shows julian date information again overlaid over other information. Julian day and next represents CURDAY and NXTDAY. jday1 and jday2 are the julian dates found in the cached files.

==Special Characters==

The following is a list of special characters available on the Prevue Grid software in the listings. These characters are drawn from the [http://ariweinstein.com/prevue/PrevueC.font.png PrevueC.font] file, but the order of the characters does not quite match up exactly with their order in the font itself. These were discovered by editing the curday.dat file, which contains the current listings cache.

* 7C - CC
* 80 - Right Triangle
* 81 - Upside-Down Right Triangle
* 82 - Right Double Triangle
* 83 - Upside-Down Double Right Triangle
* 84 - R
* 85 - PG
* 86 - ADULT
* 87 - PG-13
* 88 - Left Triangle
* 8E - VCRPlus+
* 8F - NC-17
* 90 - TVY
* 91 - Headphones
* 92 - Disney Logo
* 93 - TVY7
* 94 - 16ANS+
* 95 - HBO
* 96 - 18ANS+
* 97 - 13ANS+
* 98 - CINEMAX
* 99 - TVG

* 9B - TVPG
* 9C - WOW (Phone)
* 9D - G TOUS
* 9E - PREVUE LOGO
* 9F - SPECIAL OFFER
* A1 - TVM
* A2 - Upside-Down Exclamation Point
* A3 - TVMA
* A4+ Symbols

==Known Error Codes==
[[File:ER009.png|200px|thumb|right|ER009 is shown because TVGBANNR.UV is missing]]
* ER005 - Attempt to boot on 1.x Kickstart (cannot actually be seen, since 2.0 is the minimum KS for the Amiga FFS format)
* ER007 - No listings data available
* ER009 - The wrong color palette is being used in the file defined in Banner.ini, the color palette must contain 8 colors
* ER010 - The resolution of the file defined in banner.ini is too large
* ER011 - Insufficient chip or fast RAM available
* ER012 - Too much chip ram (2MB+ throws this error!)

'''0 <NUL>''' This is still being checked

'''DREV 5 <NUL>''' Hypothesis: This is a Data Revision # - If this is changed the grid is horribly messed up. This probably matches the various versions of Prevue software.

'''KHHR <NUL>''' 4 Letter Code for the Airport that Weather Conditions are downloaded for. - Set with I select code

'''Hawthorne <NUL>''' Displayed city name for Weather Conditions - Set with I select code

'''250 <NUL>''' Julian date from 0 to 255 - resets to 0 on day 256.

'''91 <NUL>''' Number of channel listings. Decreasing this in Curday.dat will remove channels from bottom of list. This is automatically built when the channel lineup is sent and data is saved to disk.

'''130 <NUL>''' This is still being checked

'''1300 <NUL>''' This is still being checked

==The general pattern of Channel information for DREV 5:==

1 Hex Character - Value is the Julian Day - in our example '['

5 digits for Channel number (string of data - no more than 5 characters)

6 null characters

6 character Source ID (if the Source ID is less than 6 characters, null characters will fill the rest of the space)

1 null character

6 character Call Letters (if the Call Letters are less than 6 characters, null characters will fill the rest of the space)

2 null characters

1 Hex Character 1st Flag of information (None, HiliteSrc, SumbySrc, VideoTagDisable, CAF_PPVSRC, Ditto, AltHiliteSrc, Stereo)

6 Hex character Timeslot Mask (in our example showing 6 ""ÿ"" characters)

6 Hex character Blackout Mask (in our example showing 6 null characters)

1 Hex Character for Flag #2 (still working on what thie one does, possibly flags the channel for Sports and Movie Summaries)

2 Hex Characters for Background Color (colors available are determined by Gradient.ini - in our example ÿÿ)

2 Characters for Brush ID (unknown format yet - possibly string - in our example 00)

2 Null Characters

1 Hex Character for 3rd Flag of information (Grid, MR, DNICHE, DMPLEX, and CF2_DPPV - possibly 3 additional flags as well)

6 Character Source ID again

Then the listings follows after this...

Notes:

The first character (in this case of the untouched listings - '[') is the character that corresponds to the HEX code for the Julian Date. All characters are good and will reset after FF to 00. This character changes daily.

Flag 1 is created by using 2 HEX positions and the combination is converted into a single char.

The 1st HEX position controls STEREO/ALTHILITESRC/DITTO/CAF_PPVSRC
The 2nd HEX position controls VIDEO_TAG_DISABLE/SumbySrc/HiliteSrc/None

The table above breaks down what each HEX position represents.

IMPORTANT when viewing in a text editor: For channels showing None and Stereo, there is a hidden HEX Code 81 that represents flag 1) - The HEX 81 does not print on-screen and is only visible in a HEX editor.

==Timeslot & Blackout Masks==

ÿÿÿÿÿÿ<NUL><NUL><NUL><NUL><NUL><NUL>

The first 6 characters are called the Timeslot Mask
The last 6 characters are called the Blackout Mask

The Timeslot Mask controls the times that a specific channel is displayed within the grid. In our example listings, you will notice that on channel 95, the listings have both TWC and GOLF listed. You will also notice, that this block is different than all other 24hr/day channels.

The Blackout Mask controls the times that a channel is removed from the listings or displays a message that a particular program is blacked out (usually due to SyndEx Rules or Sports Blackout rules.)

How this works is that each char in the block controls a certain daypart, which is a block of 4 hours. The table below shows which character in the block controls each daypart.

{| class="wikitable" style="text-align:center" border="1";
|-
| Position 1
|5:00am to 8:59am
|-
| Position 2
|9:00am to 12:59pm
|-
| Position 3
|1:00pm to 4:59pm
|-
| Position 4
|5:00pm to 8:59pm
|-
| Position 5
|9:00pm to 12:59am
|-
| Position 6
|1:00am to 4:59am
|-
|}

For each daypart, there is a char that represents the timing as to when the channel will go into Off Air.

As a recurring theme, you guessed it... It is a HEX code. Here is how it is broken down:

The first HEX position controls the first two hours of the daypart and the second HEX position controls the last two hours of the daypart.

{| class="wikitable" style="text-align:center" border="1";

The Blackout Mask works the same way using the same dayparts. Instead of an off-air message, this block will remove the listing or list Blacked-Out.

Note: Every entry has both a Timeslot Mask and a Blackout Mask. Most 24 hour channels will have all 0xFF for the timeslot mask and all <NUL> for the Blackout Mask.

==Flag #2==

(Hex character 09 must be changed in a Hex editor only)
0-10, 11-20, 21-30, 31-40, 41-50, 51-60,61-70, 71-80, 81-90, 91-100, 101-110

HEX 03 Yellow HEX03 Yellow
HEX 06 Gray HEX anything else is white

Colors are determined in Gradient.ini file - any color listed can be used for background...

Foreground Text is either Yellow (HEX03) or White (any other HEX value)

==Flag #3==

This flag controls the MR, Grid, and DMPLEX, DNICHE, CF2_DPPV. When a listing is built by default, it will build with a HEX 03, which would turn on MR and Grid. It is still being determined how this information is transmitted, as it is not part of the original C channel lineup serial data.

'''0 <NUL>''' This is still being checked

'''DREV 5 <NUL>''' Hypothesis: This is a Data Revision # - If this is changed the grid is horribly messed up. This probably matches the various versions of Prevue software.

'''KHHR <NUL>''' 4 Letter Code for the Airport that Weather Conditions are downloaded for. - Set with I select code

'''Hawthorne <NUL>''' Displayed city name for Weather Conditions - Set with I select code

'''250 <NUL>''' Julian date from 0 to 255 - resets to 0 on day 256.

'''91 <NUL>''' Number of channel listings. Decreasing this in Curday.dat will remove channels from bottom of list. This is automatically built when the channel lineup is sent and data is saved to disk.

'''130 <NUL>''' This is still being checked

'''1300 <NUL>''' This is still being checked

==The general pattern of Channel information for DREV 5:==

1 Hex Character - Value is the Julian Day - in our example '['

5 digits for Channel number (string of data - no more than 5 characters)

6 null characters

6 character Source ID (if the Source ID is less than 6 characters, null characters will fill the rest of the space)

1 null character

6 character Call Letters (if the Call Letters are less than 6 characters, null characters will fill the rest of the space)

2 null characters

1 Hex Character 1st Flag of information (None, HiliteSrc, SumbySrc, VideoTagDisable, CAF_PPVSRC, Ditto, AltHiliteSrc, Stereo)

6 Hex character Timeslot Mask (in our example showing 6 ""ÿ"" characters)

6 Hex character Blackout Mask (in our example showing 6 null characters)

1 Hex Character for Flag #2 (still working on what thie one does, possibly flags the channel for Sports and Movie Summaries)

2 Hex Characters for Background Color (colors available are determined by Gradient.ini - in our example ÿÿ)

2 Characters for Brush ID (unknown format yet - possibly string - in our example 00)

2 Null Characters

1 Hex Character for 3rd Flag of information (Grid, MR, DNICHE, DMPLEX, and CF2_DPPV - possibly 3 additional flags as well)

6 Character Source ID again

Then the listings follows after this...

Notes:

The first character (in this case of the untouched listings - '[') is the character that corresponds to the HEX code for the Julian Date. All characters are good and will reset after FF to 00. This character changes daily.

Flag 1 is created by using 2 HEX positions and the combination is converted into a single char.

The 1st HEX position controls STEREO/ALTHILITESRC/DITTO/CAF_PPVSRC
The 2nd HEX position controls VIDEO_TAG_DISABLE/SumbySrc/HiliteSrc/None

The table above breaks down what each HEX position represents.

IMPORTANT when viewing in a text editor: For channels showing None and Stereo, there is a hidden HEX Code 81 that represents flag 1) - The HEX 81 does not print on-screen and is only visible in a HEX editor.

==Timeslot & Blackout Masks==

ÿÿÿÿÿÿ<NUL><NUL><NUL><NUL><NUL><NUL>

The first 6 characters are called the Timeslot Mask
The last 6 characters are called the Blackout Mask

The Timeslot Mask controls the times that a specific channel is displayed within the grid. In our example listings, you will notice that on channel 95, the listings have both TWC and GOLF listed. You will also notice, that this block is different than all other 24hr/day channels.

The Blackout Mask controls the times that a channel is removed from the listings or displays a message that a particular program is blacked out (usually due to SyndEx Rules or Sports Blackout rules.)

How this works is that each char in the block controls a certain daypart, which is a block of 4 hours. The table below shows which character in the block controls each daypart.

{| class="wikitable" style="text-align:center" border="1";
|-
| Position 1
|5:00am to 8:59am
|-
| Position 2
|9:00am to 12:59pm
|-
| Position 3
|1:00pm to 4:59pm
|-
| Position 4
|5:00pm to 8:59pm
|-
| Position 5
|9:00pm to 12:59am
|-
| Position 6
|1:00am to 4:59am
|-
|}

For each daypart, there is a char that represents the timing as to when the channel will go into Off Air.

As a recurring theme, you guessed it... It is a HEX code. Here is how it is broken down:

The first HEX position controls the first two hours of the daypart and the second HEX position controls the last two hours of the daypart.

{| class="wikitable" style="text-align:center" border="1";

The Blackout Mask works the same way using the same dayparts. Instead of an off-air message, this block will remove the listing or list Blacked-Out.

Note: Every entry has both a Timeslot Mask and a Blackout Mask. Most 24 hour channels will have all 0xFF for the timeslot mask and all <NUL> for the Blackout Mask.

1 Hex Character - Value is the Julian Day - in our example '['

5 digits for Channel number (string of data - no more than 5 characters)

6 null characters

6 character Source ID (if the Source ID is less than 6 characters, null characters will fill the rest of the space)

1 null character

2 Hex Characters for Background Color (colors available are determined by Gradient.ini - in our example ÿÿ)

2 Characters for Brush ID (unknown format yet - possibly string - in our example 00)

2 Null Characters

1 Hex Character for 3rd Flag of information (Grid, MR, DNICHE, DMPLEX, and CF2_DPPV - possibly 3 additional flags as well)

6 Character Source ID again

Then the listings follows after this...

Notes:

The first character (in this case of the untouched listings - '[') is the character that corresponds to the HEX code for the Julian Date. All characters are good and will reset after FF to 00. This character changes daily.

Flag 1 is created by using 2 HEX positions and the combination is converted into a single char.

The 1st HEX position controls STEREO/ALTHILITESRC/DITTO/CAF_PPVSRC
The 2nd HEX position controls VIDEO_TAG_DISABLE/SumbySrc/HiliteSrc/None

The table above breaks down what each HEX position represents.

IMPORTANT when viewing in a text editor: For channels showing None and Stereo, there is a hidden HEX Code 81 that represents flag 1) - The HEX 81 does not print on-screen and is only visible in a HEX editor.

==Timeslot & Blackout Masks==

ÿÿÿÿÿÿ<NUL><NUL><NUL><NUL><NUL><NUL>

The first 6 characters are called the Timeslot Mask
The last 6 characters are called the Blackout Mask

The Timeslot Mask controls the times that a specific channel is displayed within the grid. In our example listings, you will notice that on channel 95, the listings have both TWC and GOLF listed. You will also notice, that this block is different than all other 24hr/day channels.

How this works is that each char in the block controls a certain daypart, which is a block of 4 hours. The table below shows which character controls each daypart.

{| class="wikitable" style="text-align:center" border="1";
|-
| Position 1
|5:00am to 8:59am
|-

|-

|-
| Position 5
|9:00pm to 12:59am
|-
| Position 6
|1:00am to 4:59am
|-
|}

For each daypart, there is a char that represents the timing as to when the channel will go into Off Air.

As a recurring theme, you guessed it... It is a HEX code. Here is how it is broken down:

The first HEX position controls the first two hours of the daypart.

The second HEX position controls the last two hours of the daypart.

The Blackout Mask works the same way, instead this time it will remove the listing or list Blacked-Out.

Note: Every entry has both a Timeslot Mask and a Blackout Mask. Most 24 hour channels will have all 0xFF for the timeslot mask and all <NUL> for the Blackout Mask.

'''130 <NUL>''' This is still being checked

'''1300 <NUL>''' This is still being checked

==The general pattern of Channel information for DREV 5:==

1 Hex Character - Value is the Julian Day - in our example '['

5 digits for Channel number (string of data - no more than 5 characters)

6 null characters

6 character Source ID (if the Source ID is less than 6 characters, null characters will fill the rest of the space)

1 null character

6 character Call Letters (if the Call Letters are less than 6 characters, null characters will fill the rest of the space)

2 null characters

1 Hex Character 1st Flag of information (None, HiliteSrc, SumbySrc, VideoTagDisable, CAF_PPVSRC, Ditto, AltHiliteSrc, Stereo)

6 Hex character Timeslot Mask (in our example showing 6 ""ÿ"" characters)

6 Hex character Blackout Mask (in our example showing 6 null characters)

1 Hex Character for Flag #2 (still working on what thie one does, possibly flags the channel for Sports and Movie Summaries)

2 Hex Characters for Background Color (colors available are determined by Gradient.ini - in our example ÿÿ)

2 Characters for Brush ID (unknown format yet - possibly string - in our example 00)

2 Null Characters

1 Hex Character for 3rd Flag of information (Grid, MR, DNICHE, DMPLEX, and CF2_DPPV - possibly 3 additional flags as well)

6 Character Source ID again

Then the listings follows after this...

Notes:

The first character (in this case of the untouched listings - '[') is the character that corresponds to the HEX code for the Julian Date. All characters are good and will reset after FF to 00. This character changes daily.

Flag 1 is created by using 2 HEX positions and the combination is converted into a single char.

The 1st HEX position controls STEREO/ALTHILITESRC/DITTO/CAF_PPVSRC
The 2nd HEX position controls VIDEO_TAG_DISABLE/SumbySrc/HiliteSrc/None

The table above breaks down what each HEX position represents.

IMPORTANT when viewing in a text editor: For channels showing None and Stereo, there is a hidden HEX Code 81 that represents flag 1) - The HEX 81 does not print on-screen and is only visible in a HEX editor.

==Timeslot & Blackout Masks==

ÿÿÿÿÿÿ<NUL><NUL><NUL><NUL><NUL><NUL>

The first 6 characters are called the Timeslot Mask
The last 6 characters are called the Blackout Mask

The Timeslot Mask controls the times that a specific channel is displayed within the grid. In our example listings, you will notice that on channel 95, the listings have both TWC and GOLF listed. You will also notice, that this block is different than all other 24hr/day channels.

How this works is that each char in the block controls a certain daypart, which is a block of 4 hours. The table below shows which character controls each daypart.

{| class="wikitable" style="text-align:center" border="1";
|-
| Position 1
|5:00am to 8:59am
|-
| Position 2
|9:00am to 12:59pm
|-
| Position 3
|1:00pm to 4:59pm
|-
| Position 4
|5:00pm to 8:59pm
|-
| Position 5
|9:00pm to 12:59am
|-
| Position 6
|1:00am to 4:59am
|-
|}

For each daypart, there is a char that represents the timing as to when the channel will go into Off Air.
As a recurring theme, you guessed it... It is a HEX code. Here is how it is broken down:

The first HEX position controls the first two hours of the daypart.
The second HEX position controls the last two hours of the daypart.

How this works is that each char in the block controls a certain daypart, which is a block of 4 hours. The table below shows which character controls each daypart.

{| class="wikitable" style="text-align:center" border="1";
|-
| Position 1
|5:00am to 8:59am
|-
| Position 2
|9:00am to 12:59pm
|-
| Position 3
|1:00pm to 4:59pm
|-
| Position 4
|5:00pm to 8:59pm
|-
| Position 5
|9:00pm to 12:59am
|-
| Position 6
|1:00am to 4:59am
|-
|}

For each daypart, there is a char that represents the timing as to when the channel will go into Off Air.
As a recurring theme, you guessed it... It is a HEX code. Here is how it is broken down:

The first HEX position controls the first two hours of the daypart.
The second HEX position controls the last two hours of the daypart.

==The general pattern of Channel information for DREV 5:==

1 Hex Character - Value is the Julian Day - in our example '['

5 digits for Channel number (string of data - no more than 5 characters)

6 null characters

6 character Source ID (if the Source ID is less than 6 characters, null characters will fill the rest of the space)

1 null character

6 character Call Letters (if the Call Letters are less than 6 characters, null characters will fill the rest of the space)

2 null characters

1 Hex Character 1st Flag of information (None, HiliteSrc, SumbySrc, VideoTagDisable, CAF_PPVSRC, Ditto, AltHiliteSrc, Stereo)

6 Hex character Timeslot Mask (in our example showing 6 ""ÿ"" characters)

6 Hex character Blackout Mask (in our example showing 6 null characters)

1 Hex Character for Flag #2 (still working on what thie one does, possibly flags the channel for Sports and Movie Summaries)

2 Hex Characters for Background Color (colors available are determined by Gradient.ini - in our example ÿÿ)

2 Characters for Brush ID (unknown format yet - possibly string - in our example 00)

2 Null Characters

1 Hex Character for 3rd Flag of information (Grid, MR, DNICHE, DMPLEX, and CF2_DPPV - possibly 3 additional flags as well)

6 Character Source ID again

Then the listings follows after this...

Notes:

The first character (in this case of the untouched listings - '[') is the character that corresponds to the HEX code for the Julian Date. All characters are good and will reset after FF to 00. This character changes daily.

Flag 1 is created by using 2 HEX positions and the combination is converted into a single char.

The 1st HEX position controls STEREO/ALTHILITESRC/DITTO/CAF_PPVSRC
The 2nd HEX position controls VIDEO_TAG_DISABLE/SumbySrc/HiliteSrc/None

The table above breaks down what each HEX position represents.

IMPORTANT when viewing in a text editor: For channels showing None and Stereo, there is a hidden HEX Code 81 that represents flag 1) - The HEX 81 does not print on-screen and is only visible in a HEX editor.

==Timeslot & Blackout Masks==

ÿÿÿÿÿÿ<NUL><NUL><NUL><NUL><NUL><NUL>

The first 6 characters are called the Timeslot Mask
The last 6 characters are called the Blackout Mask

The Timeslot Mask controls the times that a specific channel is displayed within the grid. In our example listings, you will notice that on channel 95, the listings have both TWC and GOLF listed. You will also notice, that this block is different than all other 24hr/day channels.

How this works is that each char in the block controls a certain daypart, which is a block of 4 hours. The table below shows which character controls each daypart.

For each daypart, there is a char that represents the timing as to when the channel will go into Off Air.
As a recurring theme, you guessed it... It is a HEX code. Here is how it is broken down:

The first HEX position controls the first two hours of the daypart.

The first character (in this case of the untouched listings - '[') is the character that corresponds to the HEX code for the Julian Date. All characters are good and will reset after FF to 00. This character changes daily.

Flag 1 is created by using 2 HEX positions and the combination is converted into a single char.

The 1st HEX position controls STEREO/ALTHILITESRC/DITTO/CAF_PPVSRC
The 2nd HEX position controls VIDEO_TAG_DISABLE/SumbySrc/HiliteSrc/None

The table above breaks down what each HEX position represents.

IMPORTANT when viewing in a text editor: For channels showing None and Stereo, there is a hidden HEX Code 81 that represents flag 1) - The HEX 81 does not print on-screen and is only visible in a HEX editor.

==Timeslot & Blackout Masks==

ÿÿÿÿÿÿ<NUL><NUL><NUL><NUL><NUL><NUL>

The first 6 characters are called the Timeslot Mask
The last 6 characters are called the Blackout Mask

The Timeslot Mask controls the times that a specific channel is displayed within the grid. In our example listings, you will notice that on channel 95, the listings have both TWC and GOLF listed. You will also notice, that this block is different than all other 24hr/day channels.

How this works is that each char in the block controls a certain daypart, which is a block of 4 hours. The table below shows which character controls each daypart.

{| class="wikitable" style="text-align:center" border="1";
|-
| Position 1
|5:00am to 8:59am
|-
| Position 2
|9:00am to 12:59pm
|-
| Position 3
|1:00pm to 4:59pm
|-
| Position 4
|5:00pm to 8:59pm
|-
| Position 5
|9:00pm to 12:59am
|-
| Position 6
|1:00am to 4:59am
|-
|}

For each daypart, there is a char that represents the timing as to when the channel will go into Off Air.
As a recurring theme, you guessed it... It is a HEX code. Here is how it is broken down:

The first HEX position controls the first two hours of the daypart.
The second HEX position controls the last two hours of the daypart.

NUL Char will drop the listing from the list
ü char will show the listing for the times that have ÿ
ETX will show the off-air message.
À will hide the listing

==Flag #2==

(Hex character 09 must be changed in a Hex editor only)
0-10, 11-20, 21-30, 31-40, 41-50, 51-60,61-70, 71-80, 81-90, 91-100, 101-110

==Color Flags:==
flag1 = 0x%02X, flag2 = 0x%04X, BgColor = 0x%02X, FgColor = 0x%02X, BrushId = %s
‚ ÿ ÿ 00<nul><nul>

HEX 03 Yellow HEX03 Yellow
HEX 06 Gray HEX anything else is white

Colors are determined in Gradient.ini file - any color listed can be used for background...

Foreground Text is either Yellow (HEX03) or White (any other HEX value)

==Flag #3==

This flag controls the MR , Grid, and DMPLEX, DNICHE, CF2_DPPV.

'''DREV 5 <NUL>''' Hypothesis: This is a Data Revision # - If this is changed the grid is horribly messed up. This probably matches the various versions of Prevue software.

'''KHHR <NUL>''' 4 Letter Code for the Airport that Weather Conditions are downloaded for. - Set with I select code

'''Hawthorne <NUL>''' Displayed city name for Weather Conditions - Set with I select code

'''250 <NUL>''' Julian date from 0 to 255 - resets to 0 on day 256.

'''91 <NUL>''' Number of channel listings. Decreasing this in Curday.dat will remove channels from bottom of list. This is automatically built when the channel lineup is sent and data is saved to disk.

'''130 <NUL>''' This is still being checked

'''1300 <NUL>''' This is still being checked

==The general pattern of Channel information for DREV 5:==

1 Hex Character - Value is the Julian Day - in our example '['

5 digits for Channel number (string of data - no more than 5 characters)

6 null characters

6 character Source ID (if the Source ID is less than 6 characters, null characters will fill the rest of the space)

1 null character

6 character Call Letters (if the Call Letters are less than 6 characters, null characters will fill the rest of the space)

2 null characters

1 Hex Character 1st Flag of information (None, HiliteSrc, SumbySrc, VideoTagDisable, CAF_PPVSRC, Ditto, AltHiliteSrc, Stereo)

6 Hex character Timeslot Mask (in our example showing 6 ""ÿ"" characters)

6 Hex character Blackout Mask (in our example showing 6 null characters)

1 Hex Character for Flag #2 (still working on what thie one does, possibly flags the channel for Sports and Movie Summaries)

2 Hex Characters for Background Color (colors available are determined by Gradient.ini - in our example ÿÿ)

2 Characters for Brush ID (unknown format yet - possibly string - in our example 00)

2 Null Characters

1 Hex Character for 3rd Flag of information (Grid, MR, DNICHE, DMPLEX, and CF2_DPPV - possibly 3 additional flags as well)

6 Character Source ID again

Then the listings follows after this...

Notes:

The first character (in this case of the untouched listings - '[') is the character that corresponds to the HEX code for the Julian Date. All characters are good and will reset after FF to 00. This character changes daily.
