摘要： A data communication architecture delivers a wide variety of content, including audio and video content, to consumers. The architecture employs channel bonding to deliver more bandwidth than any single communication channel can carry. The architecture includes intermediate network devices that may receive content and send content using different groups of communication channels. The network device may process content received across a first set of communication channels for transmission across a second set of communication channels different from the first set. Such processing may preserve a program order of the content during delivery to a destination device.

摘要： In an example, a method of processing data includes transmitting data over a network at a first bit rate, identifying a reduction in a network link rate of the network from a first network link rate to a second network link rate, and in response to identifying the reduction in the network link rate, determining a recovery bit rate at which to transmit the data over the network, where the recovery bit rate is less than the second network link rate. The method also includes determining a buffering duration based on a difference between a time of the identification of the reduction in the network link rate and an estimated actual time of the reduction in the network link rate, and determining a recovery rate duration during which to transmit the data at the recovery bit rate based on the recovery bit rate and the buffering duration.

摘要： A server system assigns a group of user sessions to a single modulator. The user sessions comprise data in a plurality of classes, each class having a respective priority. The plurality of classes includes, in order of priority from highest priority to lowest priority, audio data, video data, and user-interface graphical elements. The server system determines that an aggregate bandwidth for a first frame time exceeds a specified budget for the modulator. In response to determining that the aggregate bandwidth for the first frame time exceeds the specified budget, the server system transmits an allocated portion of the data for the group of user sessions through the modulator onto a channel corresponding to the modulator during the first frame time in accordance with the class priorities.

摘要： The invention relates to a method for managing multimedia content capable of being played back by a terminal (2-4) of a network (1, 12) connected to a service gateway (6). The content is capable of being transcoded according to a plurality of initial levels (N1…N10) and at least one target level (R1…R3). The method is characterised by including the steps of: receiving a request (E12, C@N2) to play back content (C) according to a first initial level (N2); updating (E13) at least one target level (R'1, R'2, R'3) taking into consideration said initial level (N2).

摘要： One embodiment of the present invention sets forth a technique for adapting playback bit rate in a content delivery system based on scene complexity of the video content as well as network conditions and other performance factors. A scene complexity map of the video content indicates the complexity levels of different scenes within the video content. Using the scene complexity map, a content player may download scenes of lower scene complexity levels from video streams encoded to lower bit rates to manage the bandwidth consumed to download the video content and allow for the downloading of scenes of higher complexity levels from video streams encoded to higher bit rates.

摘要： A server device is configured to be able to transmit content data having one of a plurality of bit rates. While receiving the content data, a client device stores a received portion thereof and reproduces content based on the stored data. A delivery system acquires a period of time during which content can be reproduced (remaining reproduction time) based on a portion of the stored data that has not been reproduced. The delivery system calculates, according to a predetermined procedure, a correction amount for correcting the bit rate based on the remaining reproduction time, and changes the bit rate based on the calculated correction amount. When the bit rate is within a predetermined range, the delivery system calculates a correction amount having a smaller magnitude than a magnitude of the correction amount calculated according to the procedure.
