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 telev...

Embodiment Construction

[0036]In the following description, reference is made to the accompanying drawings which form a part hereof, and which is shown, by way of illustration, several embodiments of the present invention. It is understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the present invention.

Audio-Visual Information Transception and Storage

[0037]FIG. 1 is a diagram depicting an exemplary embodiment of a video coding-decoding (codec) system 100 that can be used for transmission and / or storage and retrieval of audio and / or video information. The codec system 100 comprises an encoding system 104, which accepts audio-visual (AV) information 102 and processes the AV information 102 to generate encoded (compressed) AV information 106, and a decoding system 112, which processes the encoded AV information 106 to produce recovered AV information 114. Since the encoding and decoding processes are not lossless, the recovered AV information...

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 ...
