How to demux from Line-Interlaced mode of TVP5158?

Other Parts Discussed in Thread: TVP5158

Hi:

    Our HW platform is: TVP5158 + DM6467T

    Our capture mode is Line-Interleaved mode of 4-CH D1

    Now, I want demux every D1 from the Super-Frame, but I'm confused by some Bit-Fields of "4-Byte Start Code for Active Video Line (page 29 of SLES243B)". They are BOL、EOL、BOP、EOP。

    Except for Table 3-13 of SLES243B, I can't find more detail information about they.

    Could you offer me some detail information about this Fields, and how to using them.

    Thanks a lot.

    Hi,

    BOL and EOL can be used to help identify lines in split-line and hypbrid modes.  When split-line D1 is used, for example, a D1 line is transmitted as 2 split lines.  The first half of the line will have BOL=1/EOL=0 and the second half of the line will have BOL=0/EOL=1.  CIF full lines wil have BOL=1/EOL=1 for each line.

    I could not find any reference to BOP or EOP in the datasheet.
