A receiver for television signals is arranged to receive video signals comprising video data and information data. The receiver is arranged to respond to viewer operation of a control device (28). The receiver includes a processor (23) for processing selected information data to convert the same into signals representative thereof for output to a television in combination with the video signals. In one mode of operation the decoder responds to manipulation of the control device by causing brief scheduling information pertaining to programmes transmitted in the received signal to be displayed. In another mode of operation, the receiver is arranged to display detailed scheduling information pertaining to plural different television signals. The receiver is operable to receive signals containing video data representing a plurality of video clips. The processor is arranged to process the signals and to cause simultaneous display of the clips on a television screen. The processor is arranged to respond to user manipulation of the control device by storing data for subsequent viewing of user selected programmes. The decoder may further comprise a modem (32) and a CD-ROM drive (25a).

摘要:
A receiver for receiving television signals is arranged to receive signals in a plurality of channels. Each signal defines a television program and at least a signal in one of the channels comprises compressed data defining broadcast events in the channels from time to time. The receiver is arranged to produce output signals defining an image of events in the program schedule for displaying on a television screen. The receiver comprises means for receiving data defining a dictionary representing text portions, means for decoding the program scheduling data to identify text portions in the dictionary, and means for constructing the image of events from the identified text portions. A signal in each channel comprises a bouquet identity and a sub-bouquet identity for the channel. The receiver comprises means for storing a reference bouquet identity and one or more reference sub-bouquet identities, means for comparing the bouquet identity and sub-bouquet identity for a channel in a received signal with the reference bouquet and sub-bouquet identities and means for outputting the received television signal for display of the program or other services defined thereby depending on the comparison.

A receiver for television signals is arranged to receive video signals comprising video data and information data. The receiver is arranged to respond to viewer operation of a control device. The receiver includes a processor for processing selected information data to convert the same into signals representative thereof for output to a television in combination with the video signals. The receiver is arranged to respond to the information data to output for display data derived from said image data and said information data and representing an inter-active image. The receiver is responsive to viewer manipulation of the control device to vary the interactive image and to establish a telecommunications link to a remote site for on-line interaction via the interactive image between the viewer and the remote site. The interactive image may form part of an interactive services interface comprising a broadcast entry level and plural broadcast interactive levels. The interactive services interface may comprise one or more on-line interactive levels entered from one of the broadcast interactive levels for establishing an on-line connection with a remote site.
摘要:
A receiver (3) for television signals has a primary video output (22a) connected to a primary TV (2a) and a secondary video output (22b) connected to a secondary TV (2b) at a remote location (42b). The receiver (3) can be controlled by an infrared remote control (28) either directly or from the remote location (42b) via a remote control extender (40). The primary TV (2a) may be a widescreen TV with a 16:9 picture format, while the secondary TV (2b) has a 4:3 picture format. The receiver (3) can output video signals suitable for either format, but must apply the same format to both the primary and secondary video outputs (22a, 22b). The receiver (3) detects whether control signals are arriving directly or via the remote control extender, and automatically selects the correct format. In another embodiment, a wireless audio base station (55) is connected to the receiver (3) for relaying audio signals and programme data to a wireless audio receiver (60). The programme data is encoded as characters for display by the wireless audio receiver (60). The wireless audio receiver (60) also relays user control signals back to the base station (55) for controlling the output of the receiver (3). This embodiment allows convenient listening to radio stations and display of programme information.
