This Figure shows an example of down-scaling a video frame. It assumes that the input video frame is from live external video and the output video frame is to live external video. The bandwidth requirement in this case is the peak bandwidth and has to take into account bursts of video at the higher frequency.
In the example in This Figure , Table: Down-scaling Live-Video Example Minimum Bandwidth and Frequency Requirements shows the input and output minimum frequency and minimum bandwidth requirements, assuming a data width of 16 and a 60 frames-per-second frame rate.
