Abstract:
1. A method of isochronous communication management between audio/video (AV) devices, comprising: maintaining forwarding information including dynamic lane information for forwarding data between AV devices, wherein each AV device includes multiple input/output (I/O) ports each including multiple communication lanes for connecting an AV device to another AV device via a communication link, wherein the multiple communication lanes are selectively assigned; using the forwarding information to communicate AV path set-up request and response control messages between a source AV device and a destination AV device via said communication link, to establish AV path streams for bi-directional isochronous AV data streaming between the source AV device and the destination AV device, wherein a portion of the multiple communication lanes are selectively used for AV data communication in one direction and a remaining portion of the multiple communication lanes are enabled for AV data communication in a different direction; and streaming isochronous AV data in a switched network of the AV devices using the forwarding information.
