Hello, I am interested in having ADV7800 to take Composite, S-video, Component, RGB SCART, and RGB VGA inputs and deliver 30-bit 4:4:4 RGB digital output, so I can use it with a big scaler IC.
However, I don't want ADV7800 to have any extra processing, but rather just deliver the output without latency or input lag... besides usual conversion which won't be anything.
Therefore, I don't need any 3D comb or any other effect... so, can I use it without external RAM IC?
I believe it is controlled with I2C to have all the inputs and one output, is there any simple way of just outputting one of the inputs directly? I mean no "script" or anything complicated, no features choice, or so,... just choose SCART or S-video. or anything.
I saw that in the schematic within datasheet, it had the S-video Y connected to CSync pin of SCART connector. and the RGB coming from SCART in this case won't have the CSYNC fed into ADV7800. Kindly explain, since I need all the 5 inputs to be select able.
Also, I don't want to set the input resolution manually, but rather it takes it automatically then digitize it. So basically all I want is to take these inputs, pick between them, then output it as digital 444 RGB video on pixels. No need for HDMI since I don't own a license and won't get one.
added extra requirements.
