Abstract
A video transcoding system includes a video decoder, a video encoder, and a video interface. The video decoder is configured to decode a received video signal. The video encoder is configured to encode video data decoded from the received video signal by the video decoder. The video interface couples an output of the video decoder to an input of the video encoder and is configured to transfer video data having a first chroma subsampling ratio. The video decoder is further configured to provide video data having a second chroma subsampling ratio that includes fewer chrominance samples than the first chroma sampling ratio to the video interface, and to provide non-video information generated from decoding the received video signal to the video interface using video interface bandwidth usable based on a difference between the first chroma subsampling ratio and the second chroma subsampling ratio.
