  • Television receiver system having facility for storage and display of character information selected from digitally encoded broadcast transmissions
    Patent number: 4052719
    Abstract: According to the invention, a television receiver system comprises selector equipment for selecting information in the form of coded characters, received separately from any picture signals, from a single information channel or a small number of information channels and routing the selected information to a storage device, and a reading device operable, when actuated, to read the information from the storage device repeatedly and feed it, via a character generator, for display by an intensity modulated raster.

  • System for processing data signals for insertion in television signals
    Patent number: 3996583
    Abstract: In any television transmission system there are periods during which the wide-band picture signals are absent. The invention provides a signal generator system for the transmission of digital information representing a series of pages of alphanumeric or graphical symbols piecewise during these periods. At least one peripheral generating device is provided for supplying digitized data to a main storage device (conveniently of the magnetic disc type) and transfer means is operable to read out portions of the data from the main storage device and store them temporarily in a second storage device. Discharge means is operable to discharge portions of the data from the second storage device at intervals to provide output signals for insertion in a television signal during periods as aforesaid.

  • Biphase digital television systems
    Patent number: 3961137
    Abstract: Apparatus for processing groups of digital data for transmission comprises a run-in signal generator for providing at the output of the apparatus an output in which the groups of data are each preceded by a run-in signal, said apparatus being so constituted that the output is in the form of digital signals of the complemented type, and a start code generator operable to provide a start code with at least one break of complementation and arranged to insert a start code between each group and its preceding run-in signal.The apparatus is especially suitable for the transmission of data intermittently, e.g. during periods of a television signal unoccupied by wide-band picture signals. Because of the complementation break, the start code cannot arise from a data combination. Good reliability of reception is achieved on channels susceptible to interference.
