摘要： A complexity-driven adaptive quality scheme for managing segment delivery and bandwidth allocation in an ABR network. Segments for downloading to a requesting ABR client may be selected based on encoding complexity data associated therewith, wherein a virtual segmenter may operate to represent the media segments in a memory using associated pointers. In a bandwidth management configuration using a WFQ scheduling mechanism, delivery weights may be modified based on the complexity data.

摘要： A system and method for effectuating channel changes in a multicast adaptive bitrate (MABR) streaming network using a dedicated bandwidth pipe for burst transmitting a requested channel's data. A video management agent is configured to stitch burst-transmitted data with the regular channel stream during the channel change to generate a hybrid stream, which is multicast streamed toward the requesting device. Once the data from the regular channel stream is properly joined, burst transmission ceases and the bandwidth consumed for sending burst-transmitted data is released.

摘要： A system and method for effectuating channel changes in a multicast adaptive bitrate (MABR) streaming network using temporarily borrowed bandwidth from a shared progressive download ABR bandwidth pipe for downloading a requested channel's data in a recovery segment by issuing an HTTP request. A video management agent is configured to stitch the recovery segment's data with the regular channel stream during the channel change to generate a hybrid stream, which is multicast streamed toward the requesting device. Once the data from the regular channel stream is properly joined, recovery segment downloading ceases and the bandwidth consumed for sending recovery data is released back to the progressive download ABR pipe.

摘要： A complexity-driven adaptive quality scheme for managing segment delivery and bandwidth allocation in an ABR network. Upon determining an average video complexity or ECM value for media content over a select time duration, a delivery weight parameter may be obtained as a function of the average ECM value and a policy-defined weight to be used in a weighted fair queuing (WFQ) process for delivering the media content to a requesting ABR client device. The delivery weight parameter may then be applied in the WFQ process for streaming the media asset to the ABR client device until all media segments are delivered.
