Abstract: A method and apparatus for ensuring a correct satellite signal connection. Specifically, a user selects a satellite signal via an integrated receiver/decoder (IRD) from at least one satellite, and the IRD sends a command signal to a selector switch to acquire and lock onto said satellite signal. The IRD repeats transmission of the command signal to the selector switch once the IRD has acquired and locked onto said information signal. Thus, in the event that the selector switch failed to switch to a low noise block converter (LNB) corresponding to the initial command signal, then the repeated command signal helps to ensure that the selector switch switches to the LNB corresponding with the latest command signal sent by the IRD.

Abstract: The invention involves transmission download of data to plural, mass storage medium-based remote users (16a, 16b, 16c) of content (18) or software upgrades (22) or multiple versions. Optionally provided are pre-download scheduling of one or more future download sessions and post-download remote scripted software execution by the remote clients (16a, 16b, 16c). For purposes of more efficient use of the transmission link, low-volume scheduling information or content are transmitted within designated narrow-bandwidth sub-channels or trickle streams allocated within the broad bandwidth of the transmission channel and such allocation may be dynamic to vary the allocation based upon relative high-volume, high-speed and low-volume, low-speed demands. The implemented software resides primarily in the server (12) connected with the transmission provider (14). The software schedules allotted bandwidth within the broadcast band of the transmission link and formats high-volume data for transmission within sub-allocation channels logically devised therein. Client software distributed home entertainment device sites (16a, 16b, 16c) for operational enhancements as well as video program or content enhancements. Client software reserves capacity on disk (20a, 20b, 20c).

Abstract: An apparatus and method are provided for transmitting audio signals from an auxiliary source (16) such as a satellite broadcast receiver or a CD or cassette player to a radio receiver (24) located, for example, in a vehicle, using a wireless link (15). The apparatus comprises a scanning device for locating open radio frequencies in the RF spectrum of the radio receiver. The apparatus displays plural RF channel options on a display device (36) and provides a selection device (30, 32 and 34) with which a user selects an RF channel. The apparatus modulates the audio signals using the selected radio frequency, and the user tunes the vehicle radio receiver to the selected RF channel. The scanning device continuously scans for open RF channels and monitors the quality of the RF channel already selected for use as the wireless link. The apparatus provides the user with an indication to select another open channel when the RF channel in use degrades.

Abstract: An apparatus and method using the forward error correction setting to enable simultaneous use of multiple modulation systems on terrestrial distribution networks including cable television system are described. The system includes a transcoder (44) having a demultiplexer (51) for demultiplexing a forward-error-correction decoded signal into a main data stream (52) with a bit rate suitable for 64-QAM cable transmission and an auxiliary data stream (53) with a bit rate approximately half that of the main data stream. Two of such auxiliary data streams can be combined to generate an output data stream with a bit rate suitable for 64-QAM cable transmission. The system also includes a satellite transmitter (31) which can adjust its convolution coding rate to either 1/2 or 3/4 for 64-QAM and 256-QAM cable channels respectively.

Abstract: A system and method enabling the concurrent provision of multiple multi-user band transmissions, each via a single cable, to a media gateway appliance, thereby providing the media gateway appliance with an increased array of user bands for the provision of program content. The multiple multi-user band transmissions can originate from a single multi-output single-cable interface, or from multiple single-output single-cable interface. This enables the switching fabric and internal tuners of a given media gateway appliance to select any one of the provided user bands and demodulate program content therefrom.
