Systems and methods for automatically generating top level index files
First Claim
1. A method for streaming a piece of content at a playback server, comprising:
- storing information for a plurality of alternative video streams corresponds with a specific piece of content, wherein the information comprises, for each of the plurality of alternative video streams, a width, a height, a video bitrate, an audio bitrate, and an encoding element identifying the encoding of the video stream;
receiving a request for content from a playback device, wherein the request comprises;
an electronic token to obtain access to the content, information indicative of a geographic location of the playback device, and device information related to the playback, device;
determining a set of alternative video streams from the plurality of alternative video streams to return based on the request;
generating a top level index file describing each of the set of alternative video streams, wherein the top level index the describes the assets that are best suited to playback on the playback device;
retrieving cryptographic information, where the cryptographic information is used to access protected streams described in the top level index file; and
providing the cryptographic information and the top level index file to the playback device using the playback server.

Abstract
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.
