Abstract: A secondary satellite radio or broadcast channel is used to broadcast advertisement clips (e.g., audio clips) to a receiver for subsequent decoding and playback. The receiver is configured for different tiers of service, e.g., one that delivers substantially advertising-free content and another that delivers content that includes more significant amounts of advertising. The content delivered to both is the same content; however, for the service tier that includes more advertising, the advertisements broadcast on the secondary channel are interleaved into the content, preferably in such a way that the continuity of the content being delivered is not compromised.

Abstract translation: 辅助卫星广播或广播频道用于将广播片段（例如，音频剪辑）广播到接收机以用于随后的解码和重放。 接收器被配置用于不同的服务层，例如提供实质上无广告的内容的接收器，另一个传送包括更多大量广告的内容。 提供给两者的内容是相同的内容; 然而，对于包括更多广告的服务层，在辅助信道上广播的广告被交织到内容中，优选地以这样一种方式使得被传递的内容的连续性不受影响。

Abstract: An apparatus and method are provided for deciphering recorded digital audio signals and using a smart card to pay for deciphering. Encrypted digital audio signals are recorded onto a recording medium, such as a compact disc or the like. When the user desires to listen to the recording, the encrypted recording is inserted into a player/recorder and a prepaid smart card is inserted into a smart card reader connected to the player/recorder. The smart card reader deducts a predetermined value from the card before allowing the player/recorder to decipher the encrypted recording, and record the deciphered audio onto a recording medium for playback.

Abstract: Connected to a satellite earth station for transmitting a broadcast signal to a communication satellite, a data (distribution) center publishes contents of stored information on a home page (HP) of the Internet to submit retrieval of users. When each user determines date to be gotten by retrieving on HP, the user transmits a request signal to the date center via a ground Internet or the communication satellite. Responsive to the request signal, the date center returns a reservation signal including a group address and a distribution scheduled time instant to a request source via the communication satellite. A user's terminal receives date with the group address at a reserved time instant, deciphers the date using a key given from the date center separately, and stores deciphered date in a memory thereof.

Abstract: A data transmission device transmits a data broadcast using a narrow unused broadcasting band in a digital broadcast, and to record the data broadcast, which has been received, on a receiving side so that the receiving side can play back the data broadcast after a data stream is totally recorded. The transmission device generates a first data stream, which is recorded on a recording medium on a receiving side, and a second data stream including audio and video data, which is transmitted as a broadcasting program. The transmission device multiplexes the first and the second data streams and then transmits the multiplexed data stream. The transmission of the multiplexed data stream is controlled so that a transmission rate for the multiplexed data stream does not exceed the maximum transmission rate, and so that a transmission rate for the first data stream becomes lower than that for the second data stream. A receiving device records the first data stream on the recording medium, and permits the first data stream to be played back for use after the transmission completes.

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.
