Other Parts Discussed in Thread: TVP5150

Hi,

I am using TVP5150 with DM365 platform.  Right now My TVP5150 is configured for YUV422 Embedded sync output mode. Document available in TI's website says Raw Video Data Output is possible, but details are not very clear.

Could you tel me how I can get Raw Video Data Output from tvp5150?

Thanks in advance .

    Hi Ravikiran,

    My understanding is that the digital outputs of the AM5150 can only be configured for 4:2:2 mode.  I believe that the "Raw Video Data" is output only as part of the ITU-656 data packet.  I haven't done this myself, but I think that you must set the TVP5150 output mode to 8-bit ITU-R BT.656 in bits 2:0 of register 0Dh (Outputs and Data Rates Select Register).  This is the default which I think you are already using.

    Luminance Processing Control Register #1 (Address 07h), bit 5 enables or disables transmitting the raw data as ancillary data in the packet.  This is enabled by default.

    Then at the receiving end you will have to extract the ancillary data from the 656 stream.
