Line ID - An issue about TVP5158!

Other Parts Discussed in Thread: TVP5158

Problem reported from Leon:

Hello Team,

     Our TVP5158 customers found an issue when repeat&fast plug on/off signal cable.

     In line interleaved mode, our output line ID will be > (hndl->chList.info[chId].height/2 - 1) . Please see attached src.raw. The following is analyze data.

 

 

       In pixel interleaved mode, the same operation will lead Hi3520 hung up or others channel’s data will appear in the current channel. Because Hi3520 cannot get the raw data like our DSP, I cannot find a solution.

 

      Would you please help me to double check it? Very thanks.

Best Regards!

    Leon,

    The line ID can be larger or smaller than standard number of line if:

    1. The input signal is non-standard
    2. The input is pulled in/out when it is in the middle of the field.  The line count does not reset until it detects a vsync.  So, the backend can ignore the line ID that is greater than height/2 - 1 if it cause any problem.

    Regards,
