  1. What's sampling format?

    This is the format to define how the three components (Y,U, V or R, G, B) are sampled,  including :


    • YUV 4:4:4: Y, U and V are all in sampling format, no being down-sampled


    • YUV 4:2:2: Y is in full sampling format, while U and V are down-sampled horizontally


    • YUV 4:2:0: Y is in full sampling format, while U and V are down-sampled both vertically and horizontally


    • RGB 4:4:4: R, G and B are all in sampling format, no being down-sampled




  2. What's interlace/progressive format?

    This is to define whether the video frame (the whole image) is a single progressive frame, or two interlaced fields


    • One single progressive frame:


    • Two interlaced fields:





  3. What's pixel packing format?

    This setting is used to specify the organization of YUV components for each pixel, whether in planar format or packed format:


    • planar format: Y values for all pixels are put together, as well as U and V, like: YYYYYY......UUUUUUU.......VVVVVV......




    • packed format: pixel YUV value are packed together as: YUV, YUV, YUV,....
