Composite video to RGB (SOG) video conversion

hello,

i am looking for solution of my work, and since its completely video related therefore first thing in mind is Analog Devices. i am task to convert a PAL 25 fps video to RGsB(sysnc on green). Actually we have a color composite video source, and we need to use this analogue video data (PAL), and feed this video to our data analyzer/computer. Data analyzer/computer takes data in RGsB format (625lines, 25fps with sync on green). therefore if we connect composite video to G pin of our data analyzer, monochrome video appears. we need a complete color video, that is RGsB. 

Does Analog devices offer solution for this conversion. It is in my mind that some AD chip can convert my composite data to YCbCr, and then use this digital data in some another AD chip to transform into RGsB(SOG), i am not sure that this would work or not.

Any solution even with multiple ICs is most welcome. Really stuck in this issue, your help will be relief for me.

regards

Aamir Akbar

  • Hello

    Thanx for your suggestions. We have started design using Adv7181c. We have also ordered the evaluation board of this chip. 

    I have one another question. Can we use Adv7341 instead of adv7393. As datasheet of adv7341 claims component RGB output. Hopefully it will provide sync on Green. The reason for this question is that the evaluation board of ADV7181C is using Adv 7341 and video encoder.  In this way we will have a solid reference for our design.
