Claim Text:
1. A method for managing quality information for dynamic adaption in a content delivery network element, comprising: selecting, via a hardware processor of the content delivery network element, one or more granularity levels for a media track comprising encoded media data; computing, via the hardware processor, 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, via the hardware processor, a quality track corresponding to the media track at the selected granularity levels, the quality track comprising the plurality of quality metrics; storing the quality track on a storage device of the network element separate from the media track; and transmitting, via a transmitter of the content delivery network element, the quality track to a client device to inform selection of the encoded media data, wherein the quality track comprises a granularity field that indicates a granularity level of the quality metrics, and wherein the granularity field is able to be set to a first value to indicate a sample granularity level, set to a second value to indicate a track run granularity level, set to a third value to indicate a track fragment granularity level, set to a fourth value to indicate a movie fragment granularity level, and set to a fifth value to indicate a sub-segment granularity level.
