I want to receive the video of 720x576i(Hz) format from the Graphic card of ATI through HDMI interface.
I set the 576i format in the Detailed timing descriptor of the EDID structure , and I can find the 1440x576i(50Hz) format in the EDID report of the Graphic card .
In my view when I choose the format of the 1440x576i, the ad9398 should decode the fomat in pixel repetition .But I find it doesn't indeed.however the pixel clk out of the ad9398 is 27M Hz
so I have two questions
1, the format of 1440x576 (50i) are the format of 720x576i(50Hz) ??.(I try other displayer , there is a 720x576i format in EDID report . I'm really confused)
2, If the first question is right ! Does the ad9398 decode the foramt of 720x576i in no-repetition way?
Does anybody apply this format,could anyone give me some advice? ,I really can't go further now.
Thanks a lot.
