Abstract
Example methods and apparatuses including a picture parallel decoder are described herein. The picture parallel decoder includes an entropy pre-processing unit, an entropy transcoding unit, and a plurality of decoders. The entropy pre-processing unit may be configured to determine dependencies between frames of an encoded bitstream and to determine slice location data within the encoded bitstream based on dependencies between the frames. The entropy transcoding unit may be configured to transcode slices of the encoded bitstream based on the dependencies between frames. The plurality of decoders may be configured to decode two or more of the transcoded slices in parallel.
