Abstract:
A sending method includes supplying a material to a plurality of audio channels that send an entirety of a music title repeatedly for a certain unit of time. The method also includes supplying digital data for forming an audio information screen associated with an audio channel being sent. The method additionally includes supplying audio data for downloading, which is compressed in a certain compression format. Further, the method includes multiplexing the entirety of the music title repeatedly sent using the plurality of audio channels, which is supplied in the supplying the material step, the digital data for forming the audio information screen associated with the audio channel being sent, which is supplied in the supplying the digital data step, and the audio data for downloading supplied in the supplying the audio data step. In addition, the method includes sending the multiplexed data.
Abstract:
A ground station multiplexes audio digital data of a plurality of audio broadcasts, GUI data, and download audio data and transmits the multiplexed signal to a receiving side through a satellite. The receiving side displays a GUI screen corresponding to an audio broadcast. When a music information selection command is input on the display screen, an audio broadcast of a music program corresponding to the music information is selected. When a music information download command is input on the display screen, download audio data corresponding to the music information is output. The download audio data is stored to a storage device so as to download audio data corresponding to a desired music title.
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:
The present invention I related to a contents provider supplies encoded contents to a transmitting station, and broadcasts the encoded contents via a satellite. At a gas station inside a service area of the satellite, a base station to receive the contents from the satellite is disposed. The contents provider transmits to each base station decoding keys to decode the transmitted contents via the Internet. The base station relates the received contents to the decoding keys to store in a large capacity memory. When a vehicle stops by at the gas station, a vehicle-mounted apparatus communicates with the base station so as to download the contents, accumulate in a memory, and reproduce. This enables digital contents to be distributed to a mobile body with small-scale equipment.
Abstract:
A system and method for time-shifting a live broadcast, and facilitating the purchase of live or time-shifted broadcast content. The device records broadcast content being listened to by user, which gives the user the option to replay content. The device and method also provides a preview service that allows the user to experience fresh media content on a regular basis, even where a live signal is not available. The broadcast source broadcasts new content on a regular basis to avoid providing users with stale content. The user identifies content using the device and data is stored that corresponds to the identified content. The broadcast source or a third-party content provider uses the corresponding data to provide the identified content to the user. In addition to audio content, the device also provides and facilitates the acquisition of video, graphics, text or any other media content.
Abstract:
A method and apparatus for providing an integrated presentation of existing media program services and secondary media program services is described. The method comprises the steps of accepting a election of a secondary media program transmitted on a secondary media program channel; accessing a mapping to determine a primary media program channel associated with the selected secondary media program channel; commanding a first tuner module to receive conditional access information associated with the primary media program channel from the primary service provider; evaluating the conditional access information to determine if a second tuner is authorized to receive the secondary media program channel; and commanding a second tuner module to receive the secondary media program if the second tuner is authorized to receive the secondary media program channel.
Abstract:
An OFDM communications system comprises broadcast providers 400, earth stations 100, repeater satellites 200, and receivers 300 (for example mobile receivers). The size of the multiplex can be increased by adding extra channels. Two channels are provided, on the in phase and quadrature components of each subcarrier.
Abstract:
A microcontroller or microprocessor-controlled broadcast receiver embedded in an external peripheral with a digital communications interface. In one embodiment, a microprocessor-controlled broadcast receiver is embedded in the housing of an external computer peripheral. The external computer peripheral is connected to a personal computer (PC) via a digital communications link such as USB (universal serial bus). Control data is relayed from the personal computer to the broadcast receiver in the external computer peripheral via the digital communications link. Audio signals received by the broadcast receiver in the external computer peripheral may also be relayed to the personal computer via the digital communications link or via an analog interface for recording storage, or manipulation by the personal computer. The broadcast receiver may also receive data signals in addition to audio signals (datacasting). The data or audio signals or both may be encrypted.
