ABSTRACT:
Embodiments of systems and methods for processing chroma samples in video are provided. One system embodiment, among others, comprises a memory with logic, and a processor configured with the logic to receive a compressed video stream that includes a picture having chroma samples and luma samples, receive in said compressed video stream a parameter set associated with the picture, receive auxiliary chroma information in said parameter set, said auxiliary chroma information corresponding to at least a portion of the chroma samples in the picture, said chroma information further corresponding to a phase shift, wherein said phase shift corresponds to a relative location of each chroma sample in said at least a portion of the chroma samples in the picture, decompress the received compressed video stream, determine the phase shift according to a value of the received auxiliary chroma information, and process the at least a portion of the chroma samples in the picture according to the determined phase shift. Other embodiments for signaling chroma information for a picture in a compressed video stream are included herein.
