Abstract

A receiver driven approach for playback of remote content is described. One embodiment includes obtaining information concerning the content of the media file from the remote server, identifying a starting location within the media sequence, identifying byte ranges of the media file corresponding to media required to play the media sequence from the starting location, requesting the byte ranges required to play the media sequence from the starting location, buffering received bytes of information pending commencement of playback, playing back the buffered bytes of information, receiving a user instruction, identifying byte ranges of the media file corresponding to media required to play the media sequence in accordance with the user instruction, flushing previous byte range requests, and requesting the byte ranges required to play the media in accordance with the user instruction.

Dependent claims

A method for obtaining media from a media file for playback on a playback device from a remote server, the media formatted to represent media as chunks, comprising:

download an index from a remote media file, using a playback engine implemented on the playback device, wherein the index is used to convert a chunk reference into a specific HTTP request for use in downloading;
request chunks for downloading based upon a received instruction and maintain a queue of the requested chunks, using the playback engine implemented on the playback device, wherein the requested chunks are downloaded by identifying media chunks corresponding to a sequence of key frames identified for the received instruction;
receive a requested chunk and remove the received chunk from the queue of requested chunks, using the playback engine implemented on the playback device;
maintain a playback queue of received chunks for playback pending commencement of playback by the playback device, using the playback engine implemented on the playback device;
and
provide chunks maintained in the playback queue to a decoder to enable playing of the media by the playback device, using the playback engine implemented on the playback device.
