A program transmitting/receiving system has a center device and a terminal device connected through a communication device to the center device. The center device has a program information memory, a program information transmitter, a broadcasting device, and a request program transmitter. The terminal device has a program information receiver, a program receiver, an image information generator, a program request signal transmitter, and a request program receiver. The memory stores a program information. The program information transmitter transmits the program information to the terminal device. The broadcasting device broadcasts the program to the terminal device in accordance with a schedule, and stores the program. The request program transmitter receives a request signal of the program from the terminal device, and transmits the program corresponding to the request signal to the terminal device. Then, the program information receiver receives the program information. The a program receiver receives the program. The image information generator generates an image information for a program selection of a user on the basis of the program information. The program request signal transmitter transmits the request signal of the program selected by the user to the center device, if the program selected in accordance with the image information is a past broadcast program. The request program receiver receives the program corresponding to the request signal.

System for and method of transmitting and receiving program, center device, and terminal device

Terminal equipment has a master terminal () and a slave terminal (), the master terminal () includes a first tuner (TA) receiving the cablecast signal for television programming delivered from the cable television station, and applying an image signal produced from the cablecast signal to a first television receiver (); a second tuner (TB) receiving a cablecast signal, and applying an image signal produced from the cablecast signal; and a transmitter/receiver (RT) radio-transmitting the image signal output from the second tuner section, the slave terminal () includes a radio-receiving section for receiving the image signal transmitted from the transmitter/receiver (RT) of the master terminal (), and applying the image signal, received by the radio-receiving section, to a second television receiver ().

Terminal equipment for cable television

A CATV station for broadcasting a television program is connected to an internet network B. The CATV station is connected to a terminal device The terminal device includes a tuner section T for receiving a broadcasting signal for the television program transmitted from the CATV station, an interface section S for making transmission/reception of a telephone signal for the internet network B and a switching circuit which is connected to the interface section, a telephone set and a public switched phone network C. The switching circuit selectively connects the telephone set to the interface section S or the public switched phone network. In this configuration, the internet telephone can be used without doing troublesome operations, and the public switched phone network or internet network can be selected according to the facility of the internet terminal device on the side of a called party so that telephone call can be executed easily.

Internet telephone system and terminal device

A method and apparatus for detecting timing pulses for descrambling a scrambled television signal, wherein a video IF signal and a sound IF signal are separated from a scrambled television IF signal by utilizing different filters, a local video carrier wave synchronized with the separated video IF signal is generated and is mixed with the separated sound IF signal for producing a beat signal, the timing pulses are detected by demodulating the main sound IF signal, and then descrambling the received scrambled television IF signal by stretching horizontal synchronizing intervals in accordance with stretch data obtained by decoding compression data contained the detected timing pulses, whereby the main sound IF signal is separated from the beat signal by attenuating the auxiliary sound IF signal with a bandpass filter.

Method and apparatus for detecting timing pulses for scrambled

A CATV signal in which a channel allocation for an FM stereo channel is superimposed on the TV audio signal. At the receiving end, the channel allocation is demodulated from the TV audio signal and is used to tune the FM tuner to the allocated channel.
