Modification of picture parameter set (PPS) for hevc extensions

Abstract

A method, apparatus, article of manufacture, and a memory structure for signaling extension functions used in decoding a sequence comprising a plurality of pictures, each picture processed at least in part according to a picture parameter set is disclosed. In one embodiment, the method comprises reading a first extension flag signaling a first extension function in the processing of the sequence and determining if the first extension flag has a first value. Further, the method reads a second extension flag signaling a second extension function in the processing of the sequence and performs the second extension function according to the read second extension flag only if the first extension flag has a first value.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims benefit of the following U.S. Provisional Patent application, which is hereby incorporated by reference: Application Ser. No. 61 / 900,906, entitled “THE MODIFICATION OF PICTURE PARAMETER SET (PPS) FOR HEVC RANGE EXTENSION,” by Yue Yu and Limin Wang, filed Nov. 6, 2013.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to systems and methods for encoding data, and in particular to a system and method for generating and processing slice headers with high efficiency video coded data.[0004]2. Description of the Related Art[0005]There is rapid growth in the technologies associated with the generation, transmission, and reproduction of media programs. These technologies include coding schemes that permit digital versions of the media programs to be encoded to compress them to much smaller size and facilitate their transmission, storage, reception and playback. These technologies ...

AI Technical Summary

Benefits of technology

The patent text describes a memory structure for signaling extension functions used in decoding a sequence that includes multiple pictures. The method involves reading a first extension flag to determine if a first extension function is needed and performing the function only if the flag has a first value. The second extension flag is then read and the second function is performed only if the first flag has a second value. This structure allows for efficient processing of the sequence and reduces unnecessary data transfer. An apparatus that includes a memory and a processor for performing these operations is also provided.

Problems solved by technology

Without compression, digital media programs are typically too large to transmit and / or store for a commercially acceptable cost.

Further, such transmissions have also evolved to include high definition media programs such as high definition television (HDTV), which have significant transmission bandwidth and storage requirements.

While this standard is adequate for cases where the extensions are truly independent, it can result in wasted operations and instructions when the extensions are not.
