Abstract
A multi-zone audio-visual (AV) system that includes: (a) one or more AV devices (such as a TV) operable to provide audio and/or visual information; (b) a set-top box (STB) associated with each AV device; (c) a router; (d) an Ethernet connection between each STB and the router; and (e) a control server which operates to receive and record data from the router, the data including data indicative of the operating status (e.g., on or off) of the or each AV device, the operating configuration (e.g., TV channel) and the time of each change of status and/or configuration of the or each AV. The system comprises at least two remote AV control devices (Human Interface Devices, “HIDs”) for each AV device. The HIDs associated with each AV device operate to be automatically synchronized to the same status and configuration. The system may include a web server and a content server.
