Abstract: 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.

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.
