摘要： A device for decoupling audio-video (AV) traffic processing from non-AV traffic processing may include a first processor and a second processor. The first processor may be configured to establish a network connection with a client device, determine whether the network connection is associated with AV traffic, transfer the network connection to a second processor when the network connection is associated with AV traffic, and process non-AV traffic associated with the network connection when the network connection is not associated with AV traffic. The second processor may be configured to receive the network connection from the first processor and process the AV traffic associated with the network connection.

摘要： A system for adaptive audio video (AV) stream processing may include at least one processor and a switch device. The switch device may be configured to route AV traffic to the processor, and to receive AV traffic from the processor and provide the AV traffic to a client device via one or more channels. The processor may monitor a transcoder buffer depth and depths of buffers associated with channels over which the AV traffic is being transmitted. The processor may adaptively modify one or more attributes associated with the AV traffic based at least on the monitored buffer depths. For example, the processor may adaptively adjust a bit rate associated with transcoding the AV traffic based at least on the transcoder buffer depth. The processor may utilize the depths of the buffers associated with the channels to adaptively adjust the amount of AV traffic provided for transmission over the channels.

摘要： Different data communication architectures deliver a wide variety of content, including audio and video content, to consumers. The architectures employ channel bonding to deliver more bandwidth than any single communication channel can carry. In some implementations, the communication architectures distribute video programming in the form of MPEG2 TS packets, flagged by marker packets, in a round-robin manner across the communication channels. Channel bonding synchronization information may be present in packets defined above the data-link layer or added to fields within data-link layer frames.

摘要： A stream at a source device may be transmitted over multiple channels. At the input of the channels the packets from the stream may be grouped into chunks. Informational packets may be appended to the chunks. The informational packets may include sequencing information for the chunks and packet-to-packet timing information. The chunks may then be distributed over the multiple channels. After transmission over the channels, the informational packets may be extracted from the chunks. Reconstruction circuitry, at the destination device, may determine the sequence of the chunks at the source device based on the sequencing information. The reconstruction circuitry may also determine relative timings of the packets within the single stream based on the packet-to-packet timing information. The packets may be released from buffers in accord with the determined packet-to-packet timing information and the sequencing information to recreate the relative timings within the single stream at the destination device.

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. In some implementations, the communication architecture communicates content according to an initial bonding configuration. The communication architecture may adjust the bonding configuration to adapt to bonding environment changes affecting the communication capabilities or requirements associated with transmitting the content.
