Patent ID: 7908631

Claim:
A method comprising: encoding, at a command receiver, a control command to adjust an output stream into a network transmissible data packet; and sending the data packet from the command receiver to a content server via a two-way communication path; wherein the control command is configured, responsive to use by the content server, to cause the content server to: adjust an output stream by at least adding metadata descriptive of content transmitted on the output stream; transmit the adjusted output stream from the content server to an output device via a one-way communication path; transmit the metadata to an input device via the two-way communication path responsive to the control command, wherein the metadata represents static content descriptive information or dynamic content descriptive information, or combinations thereof; and dynamically assign the output device identification to at least one field within a data look-up table in association with the control command responsive to an absence of the identification in the data look-up table.
