Abstract
The invention claims a method and device for content distribution and receiving . A weight ratio of a content object can be a sending caching proxy server and/or a receiver. A quality function is used for the content object between at least two quality measurement function so as to make the content object is receiver capable of sensing the weight ratio based on the quality function. The quality function can be described by a polynomial and/or a group of average value and standard difference. The quality function may be included for controlling protocol (RTCP via HTTP to dynamic self-adaptive direct current (DASH) flowing to the media display (MPD) or a real time streaming protocol (RTSP) stream of real time) reporting of a session description protocol (SDP) message.
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.
