Abstract: A receiver adapted to receive a signal having at least first and second carrier frequencies on which first and second information signals are modulated, respectively. The inventive receiver further includes circuitry for converting the received signal to a complex baseband signal. In the illustrative embodiment, the received signal includes first and second ensembles. The first ensemble includes a first signal from a first source, a first signal from a second source and a first signal from a third source. The second ensemble includes a second signal from the first source, a second signal from the second source and a second signal from the third source. The receiver is adapted to selectively output the first and/or the second ensemble. Conversion of the band is achieved with quad mixers. The outputs of the mixers are digitized and selectively provided as the first and/or the second ensemble by a digital translation stage.

Abstract: A digital audio signal processing and distribution sub-assembly unit, plug compatible or integratable with single user digital radios, for audio channels and simultaneous re-transmission to multiple user headsetss. The sub-assembly will enable multiple users to select individual channels for listening, via audio headsets, from satellite digital radio broadcasts, which will encompass up to 100 channels of music and talk show programming. Headsets will have either direct wire connections to the digital radio receiver (via a jack connection), or infra-red (IR) links or RF links, which can allow the user to roam significant distances from the radio without the encumbrance of a wire link. The unit will function in automobiles or in homes, with auto usage eventually implemented with interior wiring with access jacks for the headsets built into doors and dashboards. The sub-assembly unit will be tailored to handle a variety of satellite broadcast protocols, such as OFDM (orthogonal frequency division multiple access) and CDM (code division multiple access or spread-spectrum). The sub-assembly unit is designed to integrate with the “back end” of the new generation of satellite digital radio receivers.

Abstract: A satellite direct radio broadcast system is provided which assembles bits of broadcast programs into prime rate increments, several of which are assembled into a frame. Frames are divided into symbols which are demultiplexed into alternating ones of a plurality of prime rate channels. The prime rate channels are demultiplexed onto a corresponding number of broadcast frequencies for transmission to a satellite. The satellite payload switches the symbols into time division multiplexed (TDM) data streams. The receivers process the TDM streams using service control headers (SCHs) provided therein by broadcast stations. The SCHs facilitate transmission of different service components within broadcast channel frames, association of a primary broadcast channel with one or more secondary broadcast channels on a frame-to-frame basis, and the transmission of multiframe bit streams, or auxiliary data throughout a broadcast channel that are independent of a service, in contiguous or non-contiguous frames.

Abstract: For transmitting digital HDTV signals, the HDTV signal, which is either fed with a data rate of .ltoreq.20.48 Mbit/s or which is data-reduced to such a data rate of .ltoreq.20.48 Mbit/s by means of a method utilizing the psycho-optical phenomena of the human eye, is split at the transmitter side of a broadband transmission link operating on the DSR method into two data streams of .ltoreq.10.24 Mbit/s each, and is fed to the I/Q interface of the 4PSK modulator of the DSR transmission link. These two data streams whch are transmitted to the I/Q output of the 4PSK demodulator of the DSR transmission link are then further processed thereat.

Abstract: In an on-demand radio broadcast system (600) in which the receivers (602) have the capability to store received programs, a communications channel (300) is divided into a plurality of time segments (302). Each time segment (302) is partitioned into a high priority program timeslice (304) and a low priority program timeslice (306). High priority programs (336) are broadcast in each high priority program timeslice (304). The remaining programs are broadcast during a plurality of low priority program timeslices (306). This overcomes a problem of the receivers (602) being out of contact and not having current versions of the high priority programs (336).

Abstract: The invention relates to a ground station (10) for generating a data stream (20) that comprises a main program and an additional program. Said ground station comprises a memory (12) that stores the additional program, which is for example a commercial, while the main program is a radio program produced in a sound studio. The ground station further comprises a multiplexer (14) with a first input (14a) for receiving the main program and a second input (14b) for receiving the additional program from the memory, and with an output. A control device (16) for controlling the multiplexer (14) switches, at a first interval, an output (14c) of the multiplexer (14) from the first input to the second input and at a second interval from the second input back to the first input, thereby inserting the additional program into the main program between the first interval and the second interval. The ground station further comprises a transmitter device (18) that is connected to the output of the multiplexer (14) on the input side and that is connected to a transmitting antenna (22) on the output side so as to provide the transmitting antenna with the data stream (20). The inventive method provides a simple means for inserting commercials into the data stream without requiring special devices in the sound studio. The ground station can easily detect at which intervals commercials were inserted. The commercials can be exchanged or updated via an optional remote maintenance device of the ground station with little effort.
