Abstract:
1. A method of processing H.264 compliant data comprising: allocating a plurality of regions in a memory internal to an H.264 compliant syntax parser circuit for concurrent storage of a plurality of slice headers associated with respective H.264 slice data to be processed, the method further comprising: transferring a plurality of parameter sets associated with the plurality of slice headers from an external memory to the internal memory; wherein transferring comprises: wherein the plurality of first parameter sets includes a first H.264 compliant Picture Parameter Set (PPS) and a first H.264 compliant Sequence Parameter Set (SPS) and the plurality of second parameter sets comprises a second H.264 compliant PPS and a second H.264 compliant SPS; applying the first PPS and the first SPS to a first stage of a video processing pipeline to provide processing of a first slice associated with a first one of the plurality of slice headers; wherein the first stage provides an output based on the processing of the first slice, the method further comprising: applying the second PPS and the second SPS to the first stage to provide processing of a second slice associated with a second one of the plurality of slice headers; and concurrently applying the first PPS and the first SPS to a second stage of the video processing pipeline to provide processing of the output from the first stage.
