Prevue Emulation:Curday.dat and Nxtday.dat

Curday.dat and Nxtday.dat Breakdowns...This is a Work in Progress and will be cleaned up soon...

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

IMPORTANT: For channels showing None and Stereo, there is a hidden HEX Code 81 (decimal 129) at the beginning (listings that appears to be 17 digits in the code) - The HEX 81 does not print on-screen and is only visible in a HEX editor.

Timeslot Mask - Each character in this block turns the listings on or off for channels that go off-air.

ÿÿÿÿÿÿ block is for times the grid will show specific channel / message 1 5:00am to 8:59am 2 9:00am to 12:59pm 3 1:00pm to 4:59pm 4 5:00pm to 8:59pm 5 9:00pm to 12:59am 6 1:00am to 4:59am

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 HEX F2 will appear the listing as DNICHE and DMPLEX

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>

Last Character before the last Source ID- Flag #3
