Abstract:
Techniques for serving a manifest file of an adaptive streaming video include receiving a request for the manifest file from a user device. The video is encoded at different reference bitrates and each encoded reference bitrate is divided into segments to generate video segment files. The manifest file includes an ordered list of universal resource locators (URLs) that reference a set of video segment files encoded at a particular reference bitrate. A source manifest file that indicates the set of video segment files is identified based on the request. An issued manifest file that includes a first URL and a second URL is generated based on the source manifest file. The first URL references a first domain and the second URL references a second domain that is different from the first domain. The issued manifest file is transmitted to the user device as a response to the request.

Claim (Index 1):
A system for configuring and providing manifest files for adaptive streaming video, the system comprising:\n a manifest file serving system including one or more computer servers, each said computer server in the manifest file serving system comprising:\n a processing unit including one or more processors; and \n memory coupled with and readable by the processing unit and storing therein a set of instructions which, when executed by the processing unit, causes the one or more computer servers of the manifest file serving system to:\n receive a request for a manifest file corresponding to an adaptive streaming video from a requesting device; \n determine a first content delivery network (CDN) to serve a plurality of redirect messages corresponding to the requested adaptive streaming video, wherein the first CDN corresponds to a first Internet domain; \n determine a second content delivery network (CDN) to serve a plurality of video segment files corresponding to the requested adaptive streaming video, wherein the second CDN corresponds to a second Internet domain different from the first Internet domain; and wherein the second CDN is operated separately and independently from the first CDN; \n configure a manifest file corresponding to the requested adaptive streaming video, wherein the configured manifest file includes a plurality of uniform resource locators (URLs) requesting video segment files and directed to the first domain to be served by the first CDN, wherein the first CDN is configured to respond to requests for each of the plurality of URLs with redirect messages instructing requestors to request corresponding URLs within the second domain to be served by the second CDN; and \n transmit the configured manifest file comprising the plurality of URLs to the requesting device.
