Patent ID: 8619803

Claim:
A listener system for use with an Ethernet Audio-Video Bridging (â€œAVBâ€) network, the listener system comprising: a processor; an upper layer application executable by the processor, and when executed by the processor, is configured to transmit a stream identifier identifying a data stream relevant to the listener system; and a stream reservation protocol stack executable by the processor, and when executed by the processor, is configured to: receive the stream identifier identifying a data stream relevant to the listener system from the upper layer application; receive stream advertisements on the Ethernet AVB network, each of the stream advertisements comprising a stream identifier identifying a data stream to be communicated over the Ethernet AVB network; and operate in a sparse mode and a full mode; where the stream reservation protocol stack, when operating in the sparse mode, is further configured to compare the received stream advertisements with the stream identifier received from the upper layer application, and in response to the comparison: transmit a first stream advertisement of the received stream advertisements to the upper layer application in response to a stream identifier included in the first stream advertisement matching the stream identifier received from the upper layer application, and not transmit a second stream advertisement of the received stream advertisements to the upper layer application in response to a stream identifier included in the second stream advertisement not matching the stream identifier received from the upper layer application; and where the stream reservation protocol stack, when operating in the full mode, is further configured not to compare the received stream advertisements with the stream identifier received from the upper layer application.
