Abstract: A system and method for creating a virtual media channel including video, audio, multimedia, or other data, at or near the point of reception by end users remotely controls and operation of an end user receiving device. The present invention remotely controls an input source selection at the end user receiving device in a coordinated manner. These input sources may include terrestrial digital broadcast stations, direct broadcast satellites, other broadband data networks, data stored at the end user receiving device, internet content, multimedia files, and other programs or programming. By synchronizing the delivery of programs and programming from various sources and by remotely controlling the input source selection of the end user receiving device, the present invention provides for highly efficient integration of local and national broad-cast signals, programs or programming available on other broadband networks, and programs and programming stored at the end user's receiving device. In particular, the present invention provides for the dynamic integration of programming originating from multiple sources, including integration of locally-originated programming with the programming of national program networks delivered by direct broadcast satellite providers or other satellite systems on a market-by-market basis. The present invention further provides for the direct addressing of individual end user receiving devices, allowing the creation of virtual channels of progrmming or other data that is unique to each end user or to certain classes of end users.

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: Juxtaposed on a display unit (35) connected to a control unit (31) are the contents described in a network information table of digital broadcasting data corresponding to a first network demodulated by a demodulator (42) and the contents described in a network information corresponding to a second network replaced by an NIT replacing circuit (48). An NITa is detected by an NIT detector (44) from an MPEG2 transport packet of digital broadcasting data of a satellite digital broadcasting (the first network). At least transmission frequency information contained in the NITa detected by the NITa detector (44) is converted to an NITb adapted to a CATV (the second network) by the control unit (31), the NITa contained in the MPEG2 transport packet is replaced with the NITb by the NIT replacing circuit (48), and thus an MPEG2 transport packet of digital broadcasting data of the CATV is created.

Abstract: To control a converter of a satellite receiving system the converter receives not only a dc voltage but one of two different voltages (normally 13 or 17 volt), also an alternating voltage (normally 22 kHz). It has to be possible to control more equipment along the same (coax) cable like amplifiers and switchers and to switch between more sub-bands than two. To achieve this the satellite receiver comprises a power supply unit having switching means which can combine the supplying of one of the two dc voltages with an alternating voltage continuous tone or burst as (switching) information.

Abstract: The present invention provides a satellite broadcast receiving and distribution system (10) that will permit for the transmission of vertical and horizontal or left-hand circular and right-hand circular polarization signals simultaneously via a single coaxial cable or the use of a fiber cable (16a or 16b). The system of the present invention will accommodate two different polarity commands from two or more different sources at the same time. This satellite broadcast receiving and distribution system (10) of the present invention will provide for the signals received from the satellite to be converted to standard frequencies so as to permit for signals to travel via existing wiring which the present day amplifiers can transport in buildings, high-rises, hospitals, and the like so that satellite broadcasting can be viewed by numerous individuals by way of a single satellite antenna.

Abstract: The present invention concerns a DBS receiver which serves to combine the functions of variable rate demodulation, convolutional decoding, de-interleaving and block decoding. The demodulation stage includes a novel circuit for clock synchronization. By combining the functions of these components this device provides a higher level of utility as measured in terms of reliability, simplicity, flexibility, cost effectiveness, and integration of board layout while maintaining optimum-quality signal processing.
