Method and apparatus for distribution and reception of content

摘要

A method and apparatus for distribution and reception of content are disclosed. A quality function for a content object may be sent to intermediate cache proxy servers and/or a receiver(s). The quality function provides a functional relationship between at least two quality metrics for the content object so that a perceivable quality of the content object at a receiver may be estimated based on the quality function. The quality function may be represented by a polynomial series and/or a set of mean and standard deviation values. The quality function may be included in media presentation description (MPD) for Dynamic Adaptive Streaming over HTTP (DASH) streaming, or a session description protocol (SDP) message or a Real Time Control Protocol (RTCP) sender report for Real Time Streaming Protocol (RTSP) streaming. la US al . ~ui --------- LUU, % . --- -- --- -- i c .
