Abstract:
Aspects of this disclosure generally relate to a method of retrieving video data of multimedia content. In an example, the method includes determining a first interval between switch points for a first representation of the multimedia content and a second interval between switch points for a second representation of the multimedia content, wherein the first interval is less than the second interval. The method also includes, based on the determination, submitting one or more network requests for an amount of video data from the first representation that has a playback time that is at least equal to a playback time between switch points in the second representation. The method also includes, after submitting the request for the amount of video data from the first representation, retrieving video data from the second representation.
