Abstract
Official abstract text for this publication.
System and method for decoding digital video data. The decoding system employs hardware accelerators that assist a core processor in performing selected decoding tasks. The hardware accelerators are configurable to support a plurality of existing and future encoding/decoding formats. The accelerators are configurable to support substantially any existing or future encoding/decoding formats that fall into the general class of DCT-based, entropy decoded, block-motion-compensated compression algorithms. The hardware accelerators illustratively comprise a programmable entropy decoder, an inverse quantization module, a inverse discrete cosine transform module, a pixel filter, a motion compensation module and a de-blocking filter. The hardware accelerators function in a decoding pipeline wherein at any given stage in the pipeline, while a given function is being performed on a given macroblock, the next macroblock in the data stream is being worked on by the previous function in the pipeline.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of decoding a digital media data stream, comprising: (a) receiving media data of a first encoding/decoding format; (b) configuring at least one external decoding function based on the first encoding/decoding format; (c) decoding media data of the first encoding/decoding format using the at least one external decoding function; (d) receiving media data of a second encoding/decoding format; (e) configuring the at least one external decoding fu…
