4:4:4 color space video with 4:2:0 color space video encoders and decoders systems and methods
Abstract:
A system for communicating video, the video including 4:4:4 color space frames, includes a 4:2:0 video encoder having a 4:4:4 to 4:2:0 color space frame converter and a 4:2:0 video decoder having a 4:2:0 to 4:4:4 color space frame converter, communicatively connected to the 4:2:0 video encoder. The 4:2:0 video encoder, without conversion by the 4:4:4 to 4:2:0 color space converter, communicates the video as a plurality of encoded 4:2:0 color space frames to the decoder. The 4:2:0 video decoder, without conversion by the 4:2:0 to 4:4:4 color space frame converter, saves the video as a plurality of 4:4:4 color space frames in memory. Each of the 4:4:4 color space frames in memory of the decoder device is identical to its corresponding 4:4:4 color space frame of the video at the encoder device.
