A system for decoding video data includes a processing unit. The processing unit includes a plurality of processing pipelines and a driver. The driver includes a decoder configured to generate a plurality of intermediate control maps containing control information including an indication of which macro blocks or portions of macro blocks may be processed in parallel in the plurality of processing pipelines.

System for parallel intra-prediction decoding of video data

Embodiments of a method and system for decoding video data are described herein. In various embodiments, a high-compression-ratio codec (such as H.264) is part of the encoding scheme for the video data. Embodiments pre-process control maps that were generated from encoded video data, and generating intermediate control maps comprising information regarding decoding the video data. The control maps include information regarding rearranging the video data to be processed in parallel on multiple pipelines of a graphics processing unit (GPU) so as to optimize the use of the multiple pipelines. In an embodiment, decoding is performed on a frame basis such that each of multiple, distinct decoding operations is performed on an entire frame at one time. In other embodiments, processing of different frames is interleaved. Embodiments increase the efficiency of the decoding such as to allow decoding of high-compression-ratio encoded video data on personal computers or comparable equipment without special, additional decoding hardware.

Parallel decoding method and system for highly compressed data

Embodiments of a method and system for inter-prediction in decoding video data are described herein. In various embodiments, a high-compression-ratio codec (such as H.264) is part of the encoding scheme for the video data. Embodiments pre-process control maps that were generated from encoded video data, and generating intermediate control maps comprising information regarding decoding the video data. The control maps indicate which units of video data in a frame are to be processed using an inter-prediction operation. In an embodiment, inter-prediction is performed on a frame basis such that inter-prediction is performed on an entire frame at one time. In other embodiments, processing of different frames is interleaved. Embodiments increase the efficiency of the inter-prediction such as to allow decoding of high-compression-ratio encoded video data on personal computers or comparable equipment without special, additional decoding hardware.

Method and system for parallel intra-prediction decoding of video data

A system and method for improved antialiasing in video processing is described herein. Embodiments include multiple video processors (VPUs) in a system. Each VPU performs some combination of pixel sampling and pixel center sampling (also referred to as multisampling and supersampling). Each VPU performs sampling on the same pixels or pixel centers, but each VPU creates samples positioned differently from the other VPUs corresponding samples. The VPUs each output frame data that has been multisampled and/or supersampled into a compositor that composites the frame data to produce an antialiased rendered frame. The antialiased rendered frame has an effectively doubled antialiasing factor.
