ADAPTIVE MANAGEMENT OF A MEDIA BUFFER

摘要

Embodiments disclosed herein provide systems, methods, and computer readable media that perform adaptive management of a media buffer. In a particular embodiment, a method provides receiving packets representing a media stream into the adaptive media buffer, wherein the media stream comprises a sequence of media segments structured into segment layers, and detecting loss of one or more of the packets representing one of the media segments. The method further provides estimating a round trip delay for packets between the adaptive media buffer and a sender of the media stream and determining a current depth of the media segments within the adaptive media buffer. In response to detecting the packet loss, the method provides discarding media segments within the adaptive media buffer based on the round trip delay, the current depth, and a layer of the segment layers into which each of the one or more media segments is included.

1. A method of managing an adaptive media buffer, comprising:
receiving a plurality of packets representing a media stream into the adaptive media buffer, wherein the media stream comprises a sequence of media segments structured into a plurality of segment layers; detecting loss of one or more packets of the plurality of packets, wherein the one or more packets represent a media segment of the plurality of media segments; estimating a round trip delay for packets between the adaptive media buffer and a sender of the media stream; determining a current depth of the media segments within the adaptive media buffer; and in response to detecting the loss of the one or more packets, discarding one or more media segments of the media segments within the adaptive media buffer based on the round trip delay, the current depth, and a layer of the plurality of segment layers into which each of the one or more media segments is included.
