Abstract: For providing a device for serving search/report to viewers responding to an inquiry from the viewers, about information relating to EPGs of the BS digital broadcasting and contents of the data broadcasting services, all channels of the EPGs information of the BS digital broadcasting and the content information of the data broadcasting are received, so as to establish a data base thereof, and at the same time a key-word search data base is also established, thereby supplying a EPG service and a search service, etc., responding to a request for information supply from the viewer.

Abstract: A data processing system has a dynamic type memory, a static type memory for storing data periodically read out, a central processing unit for transferring data to and from the two memories, an address generating circuit for periodically applying an address to the static type memory to read out the contents thereof, and an address selecting unit for exclusively selecting an address from the central processing unit or an address from the address generating circuit. In the system, the two memories are connected to the address selecting unit in order that the address selected by the address selecting means is supplied common to both the memories.

Abstract: In a display signal generating means in a display device for both the character display and the graphic display, address conversion means is provided for converting the addresses of one character in a plurality of lines of one character section of a memory field corresponding to a display panel into a predetermined address or addresses.

Abstract: A data processing system such as a character display system is provided with a first memory circuit for storing coded characters to be displayed, a second memory circuit for storing picture element information of characters to be displayed, and a character display drive circuit for extracting the coded character information from said first memory circuit and extracting and reproducing the picture element information from said second memory circuit. The first memory circuit includes a plurality of random access memories (RAMs). The character display system further includes an address switching circuit for successively and alternately applying an address signal from the character display drive circuit to the RAMs, and an output signal switching circuit for switching the information output signals extracted from the RAMs in synchronism with the switching operation of the address switching circuit.

Abstract: A signal editing and processing technique for converting a plurality of continuous signals, especially long term continuous audio signals respectively relating to short term still picture signals, to a transmitting signal in which signal transmission periods and pause periods are provided, having an integer ratio of time duration with each other, wherein other signals, especially the picture signals, should be transmitted. All continuous signals are sequentially converted to digital signals addressed in accordance with relevant continuous signals, and once stored in arbitrary positions of a memory, and then read out in a given multiplexed sequence corresponding to the transmission periods of the transmitting signal. The read out multiplexed digital signals are sequentially stored in another memory, and then read out with a given high speed equal to that of the signal transmission.

Abstract: A transmission system for transmitting a plurality of information signals having arbitrary time lengths through a plurality of transmission channels, wherein at a transmitter end said plurality of information signals are allotted to said plurality of transmission channels in such a manner that in each transmission channel an information signal is followed by other information signal and a control signal comprising an index of an information composed of one or more information signals, a transmission channel or channels through which said one or more information signals are transmitted and one or more timings of transition of said one or more information signals is transmitted in addition to said information signals and at a receiver end a desired information signal is selectively extracted and reproduced under the control of said control signal.

Abstract: A signal transmission system for transmitting programed information such as a programed instruction comprising at a transmitter end circuitry for producing a number of program materials and a control signal which is used at a receiver end to control the manner of sequentially connecting program materials in accordance with a response input of a student to construct at least one significant program. The system comprises at the receiver end circuitry for detecting the control signal, circuitry for extracting desired program materials in a desired sequence with the aid of the control signal in accordance with the response input of the student and apparatus for displaying the extracted desired program materials.

Abstract: A multiplex signal transmission system in which a plurality of information signals, having respectively arbitrary time durations and being arranged in time-serial form, are sequentially divided into a plurality of signal portions by a predetermined time period, said signal portions being successively allocated in time-parallel form to a plurality of transmission channels, each of which has a time duration of said predetermined time period, and being transmitted repeatedly through respectively allocated channels every said time duration, comprises a channel shift means for shifting sequentially the channel allocation of said signal portions at predetermined time periods, and a signal transmitting means for transmitting in time-parallel form said signal portions derived from said channel shift means repeatedly through every preceding channels.
