1. A system for decoding video data, the system comprising:
a plurality of processing pipelines; a z-buffer; and a driver, coupled to the z-buffer, the driver comprising a decoder, the decoder being configured to:
receive a plurality of control maps that were generated from encoded video data encoded according to a pre-defined format,write, to the z-buffer, values indicating whether macro blocks of the encoded video data are to be decoded using intra-prediction or inter-prediction, the values being based on the plurality of control maps,preprocess the plurality of received control maps to generate a plurality of intermediate control maps containing control information including an indication of which macro blocks or portions of macro blocks may be processed in parallel in the plurality of processing pipelines, andperforming Z-testing on the Z-buffer to determine whether to perform intra-prediction or inter-prediction on the encoded video data. |
