System and method for low delay fast update for video streaming

摘要

A system and method for low delay fast update, using multiple fast update pictures, for video streaming are disclosed. In one embodiment, a fast update request is received from a media client via a network by a media server to recover from packet losses. Further, one or more low delay fast update frames are generated based on packet loss statistics obtained during a steady state video streaming session by the media server. Furthermore, the generated one or more low delay fast update frames are sent to the media client to recover from the packet losses by the media server.

1. A method for low delay fast update for video streaming, comprising:
receiving a fast update request from a media client via a network by a media server to recover from packet losses; generating multiple low delay fast update frames based on packet loss statistics obtained during a steady state video streaming session by the media server, comprising:
determining whether a packet loss level during the steady state video streaming session is above an acceptable threshold value by verifying the packet loss statistics obtained during the steady state video streaming session;if so, generating the multiple low delay fast update frames including a higher number of fast update frames with a lower percentage of intra picture updates per frame; andif not, generating the multiple low delay fast update frames including a lower number of fast update frames with a higher percentage of the intra picture updates per frame;and
sending the generated low delay fast update frames to the media client to recover from the packet losses by the media server.
