The ADV7183A video decoder outputs according to the ITU-R BT.656 standard:

27Mhz clocked output.  PAL video is 25 frames/sec, 50 interlaced fields/sec.

SAV (Start Active Video) and EAV (End Active Video) codes are used before and after video data.  Blanked bytes 80h 10h 80h 10h are used for Cb Y Cr Y where there is no data.  SAV and EAV are also 4 bytes with FFh 00h 00h AV.  AV contains information about H/V/F.

576 active lines/frame (PAL).
720 active samples/line of Luminance (Y).
720 active samples/line of Chromances (Cb & Cr).
