摘要： In one embodiment, an HTTP adaptive streaming client has a processor for controlling the selectable and variable quality level of successive chunks of a multimedia program requested from and transmitted by a server. Chunks are transmitted via a communication path having a variable bandwidth. The processor uses a buffer, a hangover timer, and a plurality of statistical and processing parameters to adaptively react to changes in the bandwidth available on the communication path. Bandwidth changes determined likely to be sustained lead to corresponding changes in the quality of subsequently requested chunks. Statistical parameters based on sliding windows of multiple samples are used to determine whether bandwidth changes are likely to be sustained. The hangover timer is used both to define a sliding window and to prevent successive changes in requested quality from occurring too rapidly so as to provide a relatively smooth viewing experience to a user using the client.

摘要： A normalized cost measure is determined for each encoded video segment within each of a plurality of sequences of encoded video segments that are associated with a video program and stored in a cache memory, relative to the sequence to which the encoded video segment belongs. One or more encoded video segments are selected from among the encoded video segments in the plurality of sequences, based on the normalized cost measures. The selected encoded video segments are removed from the cache memory. An encoded video segment having a lowest normalized cost measure among the encoded video segments in the plurality of sequences may be selected, for example.

摘要： A chunk request scheduler is provided for HTTP adaptive streaming. Requests for media chunks are scheduled over a network by requesting the media chunks over at least one connection; storing the media chunks in at least one buffer; monitoring a level of the at least one buffer; and selectively switching between at least two predefined download strategies for the request based on the buffer level. Requests for media chunks can also be scheduled over a network by obtaining an ordering of the connections based on a rate of each connection; storing the media chunks in at least one buffer; and requesting the media chunks over the ordered plurality of connections based on a size of the media chunks. For example, audio chunk requests can be scheduled over TCP connections having a lower rate order and video chunk requests can be scheduled over TCP connections having a higher rate order.
