    Abstract: A device for providing adaptive bit rate streaming that includes a first transcoder configured to transcode a video stream based at least in part on an encoding characteristic to generate a first transcoded video stream, a network monitor configured to monitor network conditions including a network bandwidth of a network, an adjustment module configured to cause the transcoder to adjust the encoding characteristic in response to a change in the network conditions, an advertising module configured to advertise to a client device an ABR profile that corresponds to the first transcoded video stream, wherein the advertising module updates the advertised single ABR profile when the at least one encoding characteristic is adjusted, and a network interface configured to transmit segments of the first transcoded video stream to the client device via the network in response to requests therefor.

    Abstract: 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.

    Abstract: 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.
