Abstract: A method and structure for establishing faster transmission of Consumer Electronic Control (CEC) commands between first and second HDMI-compatible devices. The first and second devices may transmit CEC commands via a shared alternate interface, a signaling path distinct from a standard HDMI CEC interface between the first and second devices. Authentication may furthermore be performed prior to use of the alternate interface to confirm that the communication is authorized.

Abstract: A method and system for authorizing a communication interface between a first and second module comprises detecting a coupling between a first module and a second module, certifying a first pairing certificate is valid between the first module and the second module, and issuing a first operating certificate and storing the first operating certificate on at least one of the first module and the second module.

Abstract: A removable memory device is inserted into a channel information source computer, such as computer connected to the Internet, and channel map information is downloaded to it. The removable device is then removed from the source computer and engaged with a television to download the channel map into the television, thereby avoiding prolonged autoprogramming by the television's receiver.

Abstract: Methods and apparatuses for displaying broadcast history information of a plurality of episodes of a program on an audio-visual system, which enable a viewer to select a program for which the history information of each episode will be stored. In response to the viewer's selection, the audio-visual system stores the history information for the episodes of the selected program that has been received by the audio-visual system. The audio-visual system can display the history information when the viewer watches the current episode of the program in a future time.
