Abstract

Method, apparatus and system for adaptive streaming of video data over a network. The method includes: receiving, by a decoder of a video stream processing client, first video information of a video data stream through an operation of a first complexity; decoding based at least in part on the video stream processing client's decoding of the first video information by the decoder Ability to obtain client-related information; use of client-related information by the video streaming client to adapt video streaming processing from the video streaming server to the video streaming client to different overall bit rates; based at least in part on the The terminal-related information determines whether the operation of the first complexity should continue to decode subsequent video information to be received later in the video stream processing than the first video information; in response to determining that it should not proceed to decode subsequent video information, the decoder Second video information of the video data stream received after the first video information is received by an operation of a second complexity.

Description

[0001] This application is a divisional application of an invention patent application with an application date of January 3, 2011, an application number of "201180005589.9", and an invention title of "Complexity Adaptive Scalable Decoding and Stream Processing for Multi-layer Video Systems" . [0002] Cross References to Related Applications [0003] This application claims priority to US Patent Provisional Application No. 61 / 292,741, filed January 6, 2010, the entire contents of which are incorporated herein by reference. technical field [0004] This disclosure relates to multi-layer video systems. More specifically, the present disclosure relates to complexity adaptive scalable decoding and stream processing for multi-layer video systems. Background technique [0005] In recent years, several applications and systems have emerged that consider a multi-layer approach to the transmission of video media. These applications and systems may include SNR or resolution, or ti...
