Abstract

The invention pertains to a video processing system for video processing, the video processing system being arranged to assign tasks to least two parallel processing units capable of parallel processing of tasks. The video processing system is further arranged to control at least one storage device to store input video data to be processed, processed video data and a task list of video processing tasks. The video processing system is arranged to provide and / or process video data having a hierarchical enhancement structure comprising at least one basic layer and one or more enhancement layers dependent on the basic layer and / or at least one of the other enhancement layers. It is further arranged to assign at least one task of the task list to one of the parallel processing units; and to update, after the parallel processing unit has processed a task, the task list with information regarding tasks related to at least one enhancement layer dependent on the processed task. The invention also pertains to a corresponding method for parallel processing of video data.

Description

technical field [0001] The invention relates to a video processing system and a method for parallel processing of video data. Background technique [0002] Modern digital video applications use more and more processing power for video processing, eg, encoding and / or decoding. In particular, recent video coding standards such as H.264 or MPEG-4 provide high quality video processing, but require considerable computational resources. This is especially true for real-time encoding and / or decoding. [0003] On the other hand, there is a trend in modern computing technology to provide hardware capable of processing tasks in parallel, for example by using hyper-threading technology and / or multiple cores or multiple processors of a computing chip capable of processing multiple threads. However, providing efficient mechanisms to parallelize video encoding and / or decoding requires new methods and computational techniques. [0004] For example by Steven Ge, Xinmin Tian and Yen-Kuang...
