Abstract
In one embodiment, a method receives a first stream identifier for a video stream. The first stream identifier is received in a request from a client for the video stream. The method selects a virtual stream identifier for the first stream identifier where the virtual stream identifier is associated with a plurality of physical stream identifiers associated with a plurality of physical streams. A ranking of the plurality of physical stream identifiers is analyzed to select one of the physical stream identifiers. Then, the method outputs the one of the physical stream identifiers as the video stream to use in response to the request for the first stream identifier. The one of the physical stream identifiers is sent to the client to allow the client to request the respective physical stream.
