Hi Shogo,
we have done some test on game mode and the below would be useful to you
Q1 : Under Game mode w/o connecting DDR2, can ADV8003 convert following cases ?
Ans: PVSP mostly access external DDR2 memory in every mode except game mode. Game mode has some limitation like it can’t support scaling and FRC and for interlaced inputs, enabling game modes will set the output to progressive modes. So in your case scaling is not possible and you can test only interlaced input. In your list the only possible case is 1080/60(50)i ->1080/60(50)p
Q2 : We assume that above conversion process requires dedicated memory inside of ADV8003. Is this right understanding ? Is it memory for 1 or 2 frame ?
Ans: ADV8003 does not have large internal memory to save frame. We might save lines. We need to get confirm from designer and update you;
Q3 : Is there any difference in video quality between Game mode & other modes using DDR2 other than Motion adaptive de-interlacing ?
Ans: Sure there are some quality difference.
Best Regards,
