摘要:
A wireless communications system comprises a first splitter (105) separating at least two signals, a wireless circuit for processing a first signal as a wireless signal and a combiner connected to the wireless circuit (107 & 109) and the splitter (105), combining the two signals and transmitting the signals into a service area. The wireless communications system further comprises a second splitter (115) separating the wireless signal from a second signal, and a transmitter (113) for broadcasting the wireless signal.

A method and a system for providing multimedia on demand in a near multimedia on demand environment. Beginning segments (310) for each of a set of multimedia presentations which are broadcast at a periodic interval (T1-T0) are pre-recorded onto subscriber multimedia systems. Each of the beginning segments (310) are at least as long (L) as the periodic interval. Responsive to a user request (502) for performance of a selected one of the multimedia presentations, playback of a corresponding beginning segment (504) is commenced, recording of a corresponding multimedia presentation (506) for which broadcast has already begun is commenced, and playback is switched (508) from the beginning segment to the recording of the broadcast presentation when the playback content of the beginning segment correlates with content in the recording of the broadcast presentation.

A method and apparatus facilitate the retirement of interactive applications in a manner associated with an external event and a program state of the interactive application. A broadcaster (110) transmits an interactive application (170) that includes a plurality of retirement instructions associated with external events and internal program states of the interactive application (170). A broadcast receiver (140) receives an interactive application (170), stores the included retirement instructions, and executes the interactive application (170) concurrently with the display of an associated television program. The broadcast receiver (140) monitors the broadcast signal (180) for events indicating that the executing interactive application (170) is no longer appropriate for the current television program. Upon detection of such an event, the broadcast receiver (140) retrieves the stored instructions, and retires the interactive application (170) in a manner appropriate for both the detected external event and the internal program state of the interactive application (170), according to the stored instructions.
摘要:
A decoding device in TV-systems having pay-TV-channels. Each decoder (10) forms a self-contained unit, provided with at least one connection means (11) and at least one tap means (12) between which are coupled a plurality of decoding blocks (19) which are disposed parallel to each other and decode several channels simultaneously, wherein each block is adapted to convert up "its" channel to a UHF-channel of its own. Each self-contained decoding unit comprises a data channel (20) and a control logic (21) for remote control of the individual decoding blocks from a central administrative control unit.
摘要:
A system and method may include providing a media stream via a network, the media stream comprising one or more advertisement content segments, identifying aggregate information associated with a viewer, assigning the one or more advertisement content segments to one or more categories and a category score associated with the one or more categories, filtering the one or more advertisement content segments based at least in part on the one or more categories, the category score associated with the one or more categories and the aggregate information associated with the viewer, and outputting the filtered one or more advertisement content segments to the viewer.
摘要:
A system and method for filtering audio content are provided. An audio data filtering system may include an input interface to receive audio data. The system may also include an analysis module to compare a textual representation of the audio data to data identifying prohibited audio content. The system may also include a packet filter to prevent transmission of portions of the audio data matching prohibited audio content to a remote user device. The system may further include an output interface to transmit portions of the audio data not identified as prohibited audio content to the remote user device.
摘要:
The invention concerns an audiometry method on television decoder which consists in loading in each decoder a software storing data on the selected programmes and on the watching times, in non-volatile memory, and a concealed menu for activating said software; then in periodically setting up communication between a modem of the decoder and a service centre through the telephone network or a cable network also used for programme reception and transmitting the data contained in the non-volatile memory, under the software control.
摘要:
An interactive telebroadcasting network with tree architecture comprising an operating station in which the broadcasting of television programmes, images and sound programmes is controlled and a support for broad-band transmission of all the programmes is characterized in that it comprises a user derivation unit assembly (21, 25) comprising: means (50, 51a) for interrogating a user derivation unit (99); means (84, 72, 69, 68) for transmitting a programme request from the user to the operating station once the user's unit has been addressed by the operating station; means in the operating station for generating a validation signal (100) in response to the request; means (72, 80, 85, 87) arranged in the user derivation unit for selecting a programme from all the programmes broadcast dependent on the validation signal, the user derivation unit being located on the tree architecture between the operating station and the user's television receiver.
摘要:
An addressable cable television control system controls television program and data signal transmission from a central station (11) to a plurality of user stations. The data signals include both control and text signals in video line format which are inserted on the vertical interval of the television signals, thereby freeing all channels for transmission of both television and data signals. Moreover, full-channel teletext data in video line format may be transmitted on dedicated next channels with the modification of only head end processors (16). An intelligent converter (40) at each remote user location uses the data signals to control access to the system on the basis of channel, tier of service, special event and program subject matter. The converter uses a graphics display generator (118) to generate display signals for the presentation of the text data on the television receiver (36) and for the generation of predetermined messages for the viewer concerning access, emergencies and other functions. The converter processes vertical interval text data and selected full-channel text data, both transmitted in video line format. The keyboard of the subscriber (146, 168) provides a number of different functional inputs for the subscriber to interface with the system. The converter (40) also includes apparatus for interfacing with two-way interactive data acquisition and control systems.
