Carriage Of Quality Information Of Content In Media Formats

摘要

A method for managing quality information for dynamic adaption in content delivery, wherein the method comprises selecting a granularity level for an encoded media data, computing a plurality of quality metrics for the encoded media data at the selected granularity level, wherein the quality metrics are measures of coding quality of the encoded media data, generating a quality track comprising the plurality of quality metrics, and storing the quality track on a media content server separate from other tracks that are associated with the encoded media data. Also disclosed is a network device comprising a processor configured to select a granularity level for an encoded media data, and compute a plurality of quality metrics that indicate coding quality of the encoded media data at the selected granularity level, and a transmitter coupled to the processor and configured to send the quality track towards a user of the media data.

1. A method for managing quality information for dynamic adaption in content delivery, comprising:
selecting one or more granularity levels for a media track comprising encoded media data; computing a plurality of quality metrics for the encoded media data at the selected granularity levels, wherein the quality metrics are measures of coding quality of the encoded media data; generating a quality track comprising the plurality of quality metrics; and storing the quality track on a network element separate from the media track.
