TVP5158 just have one register to indicate the video format, if I used all 4 channel input, and the video format of each channel  are different, for example, Channel 1:NTSC, Channel 2:PAL,etc. What will happen on this register?

    All registers are repeated for each of the 4 cores.

    Basically register 0xfe which cores will receive I2C writes and register 0xff controls which core responds to I2C commands.

    See section 4 in the datasheet for full details of how to select which of the 4 cores are currently selected.
