Abstract: The present invention aims at providing a television receiver including a display screen capable of, in a television broadcast consisting of a multiplicity of channels, displaying information on programs being broadcast at other channels simultaneously with displaying an on-watching program. A television receiver of the present invention, comprises a screen including a channel name display area, a program schedule display area for displaying information containing a schedule of programs broadcast at channels displayed in the channel name display area, and a television broadcast display area for displaying the television broadcast received, and a display channel selection module for selecting the channel displayed in the channel name display area.

Abstract: The present invention aims at providing a TV receiver capable of relieving a burden to search for a TV program desired by a user and enabling the user to surely watch the TV program at a necessary time in a TV broadcast consisting a multiplicity of channels. The television receiver of the present invention comprises a receiving unit for receiving a television broadcast by selecting a specified broadcast channel from a plurality of broadcast channels, a control unit for controlling said receiving unit in order to receive the television broadcast of the specified broadcast channel, a means for receiving virtual channel information containing information for specifying a time zone and information related to the broadcast channel that should be selected in this time zone, a means for storing the virtual channel information, and a timer for notifying said control unit of a time.

Abstract: A first reading unit reads data stored in a second storage area of a storage medium (including reproduction management information), and stores it in another storage medium. A first reproducing unit reproduces the data read from a first storage area of a storage medium by the first reading unit. A second reading unit reads data stored by the first reading unit in another storage medium, and outputs it to a second reproducing unit. The second reproducing unit reproduces data received from the second reading unit. A controlling unit synchronizes the reproduction of the data by the first reproducing unit with the reproduction of the data by the second reproducing unit.

Abstract: An object of the present invention is to keep the scale of the connectionless function at the minimum and plan the expansion of the network scale and the ability expansion of the exchange in connectionless communication.

Abstract: A call admission control system in an asynchronous transfer mode exchange includes a unit for describing attribute parameters of a cell from the subscriber terminal; a unit for calculating, based on the attribute parameters, the average and the dispersion of the traffic speeds of the call; a unit for managing data of the average and the dispersion on each output route and data relating to each subscriber; and a unit for calculating the total average and the total dispersion of the data speeds on the selection output route; and a unit for calculating prediction values of cell abandon rate and end-to-end delay based on the average and the dispersion on the selected output route calculated by the total average and dispersion calculating unit, and for comparing the prediction values with the required service quality of cell discard rate and end-to end delay, for determining whether or not the requesting call may be connected.
