Abstract:
The present invention relates to a method and a transmitting apparatus for encoding a bitstream representing a sequence of pictures of a video stream comprising a processor and memory, said memory containing instructions executable by said processor whereby said transmitting apparatus is operative to: send a syntax element, wherein a value of the syntax element is indicative of restrictions that are enforced on the bitstream in a way that guarantees a certain level of parallelism for decoding the bitstream.

Claim (Index 1):
A method of encoding a bitstream representing a sequence of pictures of a video stream, the method comprising:\n determining an encoding constraint corresponding to a known or assumed per-core processing capability of a multi-core decoder, the encoding constraint being a spatial segmentation constraint that constrains a spatial size needed to be handled by a single core of the multi-core decoder during parallel, multi-core decoding at the multi-core decoder; encoding the bitstream subject to the constraint and thereby obtaining an encoded bitstream wherein a processing capability needed for decoding separately decodable portions of the encoded bitstream does not exceed the known or assumed per-core processing capability; generating a Sequence Parameter Set (SPS) for use in decoding the encoded bitstream, and including a syntax element in the SPS that indicates the encoding constraint; and transmitting the encoded bitstream for decoding, including transmitting the SPS, for use by a multi-core decoder in determining whether its individual cores have sufficient processing capability for decoding the separately decodable portions of the encoded bitstream.
