摘要:
The present disclosure relates to playback of video/audio streaming media data. The media stream is available from the network at multiple bit rates. When a seek operation is performed, a playback device requests a lower bit rate media stream in order to quickly fill a playback buffer so that playback can commence more readily. After a seek start-up period is complete, the playback device can return to downloading the media stream associated with higher bit rates in order to increase the quality of the playback.
