Abstract

A method of distributing audio video content is described. The method includes: receiving configuration data for a plurality of devices; for each device in the plurality of devices, computing a set of bit rates based, at least in part, on the configuration data; encoding audio video content at each bit rate in each set of bit rates to produce a plurality of encoded audio video content streams; splitting each encoded audio video content stream in the plurality of encoded audio video content streams into chunks to produce a plurality of chunked encoded audio video content streams; for each device in the plurality of devices, creating a separate index file, each separate index file including references to at least one of the plurality of chunked encoded audio video content streams; publishing a locator for each separate index file in a catalogue; and transmitting the plurality of chunked encoded audio video content streams and each separate index file to a network. Related systems, apparatus, and methods are also described.
