Adaptive bitrate management for streaming media over packet networks

摘要

A method including providing pseudo-streaming media data to a terminal; receiving a transport control protocol (TCP) acknowledgement from the terminal; estimating one or more network conditions of a network based at least in part on the TCP acknowledgement; determining an optimal session bitrate based on the estimated one or more network conditions; and providing pseudo-streaming media data to the terminal based on the optimal session bitrate.

1. A method comprising:
providing pseudo-streaming media data for transmission to a terminal, wherein the pseudo-streaming media data includes one or more sequence numbers and corresponds to one or more timestamps; causing a table to store an association between the one or more sequence numbers and the one or more timestamps; receiving one or more transport control protocol (TCP) acknowledgments from a terminal, wherein a TCP acknowledgment of the one or more received TCP acknowledgments includes a sequence number of the one or more sequence numbers and corresponds to a certain time; acquiring the timestamp from the table using the sequence number of the TCP acknowledgement; estimating one or more network conditions of a media network based at least in part on a comparison between the certain time and the acquired timestamp; determining an optimal audio bitrate and an optimal video bitrate using the estimated one or more network conditions; receiving media data that includes audio media data and video media data; encoding the audio media data using the optimal audio bitrate; encoding the video media data using the optimal video bitrate; and providing the encoded audio media data and the encoded video media data for transmission to the terminal.
