Input 720x480, output 360x240 ?

Good day!
I need to do bining video.  Is there such a case, when video input with 720x480, and at the video output  ( may be OSD or Vid0/1) 360x240? I use board DM6437.
Thanks a lot.

    In the case of the DM6437 the most efficient way of taking a 720x480 input and generating a 360x240 output would be to use the resizer module in the VPFE. There is actually a good application note with example code that discusses using the resizer here. I am not sure if I fully understood your question, is this the sort of answer you were looking for?

    I need to make a 4x4 bining the incoming video signal (720x480 -> 180x120) and then resize to 360x240 and it will be output  video signal. The question is that in any paper I've read that format for the video input and output should be the same (but I am not sure). Therefore, I would like to know, can I have different format for input and output video format. Is it possible?
    Thank you.

    It is possible to have a different input format than output format, you just have to make sure that the transition is being handled in your application properly, the act of resizing the image here is a common step in such format conversions (perhaps the only step with the video drivers handling timing and color space).

    I imagine you have a 360x240 LCD attached to the VPBE?

    Yes, LCD is 360x240.

    Thank you very much, Bernie.
