| 20080240228 | VIDEO PROCESSING ARCHITECTURE - A video-processing architecture. In a specific embodiment, the architecture includes a first set of modules that accommodate certain functional traffic flowing between each module thereof. A broadcast module broadcasts video traffic to one or more of the first set of modules. In a more specific embodiment, the first set of modules and the broadcast module are configured to facilitate Isolation of video traffic from functional traffic. The first set of modules includes plural modules having similar module architecture. The similar module of architecture includes a local memory in each of the plural modules, wherein the local memory stores video data associated with the video traffic. The local, memory includes a first memory bank for storing input pixel data and a second memory bank for storing reconstructed pixel data. | 10-02-2008 |
| 20080240233 | ENTROPY CODING FOR VIDEO PROCESSING APPLICATIONS - An entropy coding apparatus. In a specific embodiment, the entropy coding apparatus, includes a renormalization process and an encode-decision process that communicates with the renormalization process. The encode-decision process is adapted to run in parallel with the renormalization process without the renormalization process being nested therein. In a more specific embodiment, the entropy coding apparatus includes an entropy encoder that is H.264 compliant. The encode-decision process includes a first .mechanism for pre-computing certain parameters to eliminate the need to nest the renormalization process within the encode-decision process. The renormalization process and the encode-decision process are components of a Context Adaptive Binary Arithmetic Coding (CABAC) module. | 10-02-2008 |
| 20080240253 | INTRA-MACROBLOCK VIDEO PROCESSING - A system for processing sub-blocks of a macroblock of a video frame. In an example embodiment, the system includes a first module that is adapted to process each sub-block of the macroblock, wherein each sub-block is associated with a predetermined position in a first sequence. The processing of certain sub-blocks in the first sequence requires results of processing of one or more previously processed sub-blocks in the first sequence. A controller selectively enables the first module to process each sub-block of a second sequence that is altered from the first sequence so that the first module implements parallel or pipelined processing of certain sub-blocks of the macroblock. In a more specific embodiment each sub-block in the first sequence of sub-blocks is consecutively numbered 0-15 according to H.264 standards. | 10-02-2008 |
| 20080240254 | PARALLEL OR PIPELINED MACROBLOCK PROCESSING - A video processing system. In a specific embodiment, the system implements a system for processing macroblocks that includes a first module for processing a macroblock. A controller provides a first macroblock to the first module and provides a second macroblock to the first module, without waiting for the first module to complete processing of the first macroblock, when information is available to the first module to process the second macroblock. The first module may implement a pipelined processor that is adapted to process macroblocks simultaneously. Alternatively, the first module includes a first engine and a second engine, which may run in parallel as parallel engines. In a more specific embodiment, an entire image frame is treated as a single slice and processed by the system via a pipelined engines or parallel engines. | 10-02-2008 |
| 20080240587 | SELECTIVE INFORMATION HANDLING FOR VIDEO PROCESSING - A system for selectively handling information. In an example embodiment, the system includes a first mechanism for processing information pertaining to one or more sub-blocks of a macroblock in a first stream and a second stream, and outputting a first processed stream and a second processed stream in response thereto. A second mechanism selectively combines information in the first processed stream and the second processed stream and provides an updated version of the first stream or the second stream to the first mechanism in response thereto. In a more specific embodiment, the first mechanism includes a processor, such as in intra 4×4 search, module, that processes a sub-block of a macroblock by performing intra prediction for the sub-block. The processor is adapted to process sub-blocks of a macroblock in parallel, such as in a pipelined fashion or via separate engines capable of operating in parallel. | 10-02-2008 |
| 20090100482 | Conveyance of Concatenation Properties and Picture Orderness in a Video Stream - Systems and methods that provide a video stream including a first video sequence followed by a second video sequence, and that provide a first information in the video stream pertaining to pictures in the first video sequence, wherein the location of the first information provided in the video stream is in relation to a second information in the video stream, wherein the second information pertains to the end of the first video sequence, wherein the first information in the video stream corresponds to a first information type and the second information in the video stream corresponds to a second information type different than the first information type, and wherein the first information corresponds to auxiliary information. | 04-16-2009 |
