Systems and methods for automatically genenrating top level index files

摘要

Systems and methods for automatically generating top level index files for use in adaptive bitrate streaming in accordance with embodiments of the invention are disclosed. One embodiment of the method of the invention includes receiving a request from a playback device at a playback server, where the request identifies a piece of content, retrieving a list of assets associated with the identified piece of content using the playback server, filtering the list of assets using at least one predetermined criterion using the playback server, generating a top level index file describing each asset in the filtered list of assets using the playback server, and sending the top level index file to the playback device using the playback server.

主权项

1. A method of generating a top level index file, comprising:
receiving a request from a playback device at a playback server, where the request includes an electronic token that identifies a piece of content; retrieving a list of assets associated with the electronic token that identifies the piece of content using the playback server wherein each asset is a different alternative stream associated with the piece of content and each alternative stream encodes the piece of content at a different maximum bitrate; filtering the list of assets using at least one predetermined criterion using the playback server wherein the at least one predetermined criterion is associated with capabilities of the playback device; generating, using the playback server, a top level index file describing that (i) describes at least a bitrate of each asset in the filtered list of assets and (ii) identifies locations of the assets in the filtered list of assets; and sending the top level index file to the playback device using the playback server.
