Abstract
A processing device for use with a video conferencing network is provided. The processing device includes memory configured to store data and a processor. The processor is configured to determine a first sampling phase for a portion of first video data and chrominance sub-sample the portion of first video data using the first sampling phase. The processor is also configured to encode the sub-sampled portion of first video data and decode a sub-sampled, encoded portion of second video data. The processor is further configured to determine a second sampling phase at which the portion of second video data is chrominance sub-sampled and chrominance up-sample the portion of second video data using the second sample phase.
