Video decoder with adaptive outputs

Abstract

In one aspect, there is provided a video decoder including a first write port to write uncompressed video data to a first buffer in a first format adapted based on an input required by the video decoder and to suppress writing to the first buffer. The video decoder also includes a second write port to write uncompressed video data to a second buffer in a second format adapted to provide the uncompressed video data for subsequent processing external to the video decoder.

 a video decoder that receives video data as an input video stream and processes the received video stream using at least one module, wherein the video decoder includes a context manager that provides context information related to the received video data to enable processing of the received video data by the video decoder   wherein the context information includes macroblock information associated with a macroblock included in the video stream and neighboring macroblock information associated with neighboring macroblocks of the macroblock.   
     
     
         20 . The system of  claim 19  further comprising at least one processing module that further processes the received video data. 
     
     
         21 . The system of  claim 20  wherein the at least one processing module comprises an advanced video processor that provides processing before presentation of the video data on an output display. 
     
     
         22 . The system of  claim 20  wherein the at least one processing module comprises a graphics processor that provides at least one of further processing before presentation of the video data on an output display and presentation of the video data on an output display. 
     
     
         23 . The system of  claim 20  wherein the at least one processing module comprises one or more processing blocks. 
     
     
         24 . The system of  claim 19  wherein the at least one module comprises a reverse entrophy encoder that decodes video data by examining the frequency of patterns within the video data. 
     
     
         25 . The system of  claim 19  wherein the at least one module comprises an inverse image transform that performs an inverse transform of the video data to provide decompressed video data. 
     
     
         26 . The system of  claim 19  wherein the at least one module comprises a motion compensator. 
     
     
         27 . The system of  claim 19  wherein the at least one module comprises a de-blocker that processes the video data to smooth edges between adjacent blocks of data within the video data. 
     
     
         28 . The system of  claim 19  wherein the at least one module comprises a DB writer that writes the video data to one or more buffers. 
     
     
         29 . The system of  claim 19  wherein the at least one module comprises a DWB writer that writes the video data in a format for presentation. 
     
     
         30 . The system of  claim 19  wherein the processing uses a first write port adapted to write in a format dictated by the video decoder and a second write port adapted to write in a second format dictated by a device. 
     
     
         31 . A method of processing video data, the method comprising:
 receiving by a video decoder a video data as an input video stream;   processing the received video stream using at least one module; and   providing context information related to the received video data to enable the processing,   wherein the context information includes macroblock information associated with a macroblock included in the video stream and neighboring macroblock information associated with neighboring macroblocks of the macroblock.   
     
     
         32 . The method of  claim 31  further comprising processing the video data in at least one additional module. 
     
     
         33 . The method of  claim 32  wherein the at least one processing module comprises an advanced video processor that provides processing before presentation of the video data on an output display. 
     
     
         34 . The method of  claim 32  wherein the at least one processing module comprises a graphics processor that provides at least one of further processing before presentation of the video data on an output display and presentation of the video data on an output display. 
     
     
         35 . The method of  claim 32  wherein the at least one additional module comprises one or more processing blocks.
