DVD_TIMECODE Structure

The DVD_TIMECODE structure contains DVD timecode in hours, minutes, seconds, and frames.

Syntax

typedef struct tagDVD_TIMECODE") {
   ULONG Hours1   :4; 
   ULONG Hours10  :4; 
   ULONG Minutes1 :4; 
   ULONG Minutes10:4; 
   ULONG Seconds1 :4; 
   ULONG Seconds10:4; 
   ULONG Frames1  :4; 
   ULONG Frames10 :2; 
   ULONG FrameRateCode:2; 
} DVD_TIMECODE;

Remarks

DVD timecode is binary coded decimal (BCD) encoded in the format 0xHhMmSsFf, where:

• H is tens of hours
• h is hours
• M is tens of minutes
• m is minutes
• S is tens of seconds
• s is seconds
• F is tens of frames
• f is frames

To use a BCD, first create the BCD.

ULONG timeCode = 0;

Second, create a pointer to a DVD_TIMECODE structure at the address of the BCD.

DVD_TIMECODE * dvdTimeCode = ( DVD_TIMECODE * ) &timeCode;   

Then, dvdTimeCode can be used as a DVD_TIMECODE structure.

dvdTimeCode->Hours10 = 0;
dvdTimeCode->Hours1 = 2;

Finally, timeCode is passed to the IDvdControl::TimeSearch method.

TimeSearch ( timeCode );
