摘要： An apparatus and method of decoding coded video bitstreams is disclosed. The apparatus comprises a first processor and a second processor configured to operate in parallel. The main processor receives the coded video bitstream, parses it, and calls the second processor to decode the coded video bitstream to retrieve macroblock data. If an error occurs during decoding, the second processor signals the first processor, which can instruct the second processor to perform an error recovery routine. The first processor the performs dequantization and inverse DCT to recover digital pixel data from the macroblocks so that an image formed from the digital pixel data can be later displayed on a monitor.

摘要： A system and method for processing an overrun in the encoding of an input bitstream are described. In one embodiment, an overrun in the encoding of an input bitstream is determined and the severity of the overrun is determined. Finally, a current frame is encoded using a catch-up mode to process the overrun.

摘要： Systems and methods consistent with the invention relate to performing faster motion estimation through efficient use of the General Purpose Graphic Processing Unit (GPGPU) as the compute co-processor in a multi-processor architecture. Integer pel motion estimation and fractional pel motion estimation algorithms for large block sizes may be performed on the GPU, while motion estimation for smaller block sizes is performed on the central processing unit (CPU). In embodiments described herein, GPU-based integer pel motion estimation and fractional pel motion estimation algorithms are performed using kernels which are designed so that multiple thread blocks can run concurrently on a multiprocessor.

摘要： An image processing apparatus includes the following elements. A specifying unit specifies a blank region of an image of image data by using coefficient data which is decoded from encoded data, the encoded data being obtained by encoding coefficient data generated from the image data. A dividing unit divides the decoded coefficient data into first components and second components. An eliminating unit eliminates the blank region specified by the specifying unit from the first components divided from the decoded coefficient data by the dividing unit. A synthesizing unit combines the first components from which the blank region has been eliminated by the eliminating unit with the second components divided from the decoded coefficient data by the dividing unit.
