Forum Post: RE: Pixel Aspect Ratio DM8168

For me DAR (Display Aspect Ratio) is 4:3 or 16:9.

SAR (Storage Aspect Ratio) depends  on selected Resolution PAL -> 720x576 or NTSC 720x480 or am I wrong ?

For encoder we made a extension to set Sample Aspect Ratio via API.

So we are able to insert Sample Aspect Ratio information in H264. We do this for 4:3 is works as expected.

The problem we got here is to adapt 16:9 or 4:3 displays at SD video output.

I also use Wide Screen Signaling but not all displays support this feature.

So the solution can be to change the Pixel Aspect Ratio for 16:9. I think PAR currently is constant for a 4.3 DAR ?
