  • Systems and methods for performing adaptive bitrate streaming based upon the delay of each stream and the channel rate
    Patent number: 9021119
    Abstract: Systems and methods for adaptive bitrate streaming in which playback devices select streams based upon stream delay and channel rate in accordance with embodiments of the invention are disclosed. One embodiment is configured to select a first video stream from a set of alternative streams, where at least a plurality of the alternative streams are encoded to have an upper bound seek delay that is equal to or less than the upper bound seek delay of streams in the set of alternative streams that are encoded at a higher maximum bitrate, request chunks of the first video stream and store the requested chunks in the buffer, playback the buffered chunks, measure the channel data rate, and select a second video stream from the set of alternative streams, where the second video stream has a maximum bitrate that is less than the measured channel data rate.
