SWITCHING BETWEEN MEDIA STREAMS

摘要

Methods and systems for switching between media streams can use a comparison of an average bandwidth for a new stream to an observed bit rate for an existing stream in order to determine whether to switch to the new stream. A check on the amount of data buffered for the existing stream can also be performed in order to determine whether a system should switch to the new stream.

主权项

1. A method for processing media specified in one or more playlists, the method comprising:
receiving data representing a plurality of variants of a video media and determining a peak bandwidth and an average bandwidth for each variant of the video media, each variant showing the same video media but using different encodings; creating a master playlist that includes Universal Resource Indicators (URIs) for each variant, each URI for use in retrieving a media playlist for one of the variants, and the master playlist includes data that specifies the peak bandwidth and the average bandwidth for the video media for each of the variants; storing the master playlist; and transmitting the master playlist upon request from one or more client devices.
