Abstract
A decoding method and apparatus are provided for decoding an audiovisual stream that is divided into a plurality of segments. The decoding method and apparatus obtain metadata that specify a segment out of the plurality of segments. The metadata is described in a structured description. The segment that is specified by the metadata is obtained, and a start time for rendering the segment from the metadata is derived. The segment is decoded based on the metadata to generate decoded segment data before the start time.
Claims7
A decoding method for decoding an audiovisual stream that is divided into a plurality of segments, the decoding method comprising:
- obtaining metadata that specify a segment out of the plurality of segments, the metadata being described in a structured description;
- obtaining the segment specified by the metadata;
- deriving a start time for rendering the segment from the metadata;
- and
- decoding the segment based on the metadata to generate decoded segment data before the start time.
