Abstract: Controllable units such as a television set or a playback unit are connected to a home network. A gateway connects the home network with the Internet and, at the same time, forwards externally-supplied data to the home network. A portable terminal sends HTML data for controlling controllable units and allows a user to browse HTML data sent from the gateway, either via a wireless data communication line at home or via the Internet away from home.

Abstract: A method of controlling remote control electronic apparatus coupled to a network and a remote control electronic apparatus to be coupled to a network are disclosed. Each remote control electronic apparatus has a CPU and a ROM including a local control program expressed by an independent language which is interpretable by the CPU, a remote control program expressed by a virtual language, a virtual language processing program for processing the virtual language to make it interpretable by the CPU. When one remote control electronic apparatus is required to control another remote control electronic apparatus coupled to the network, the remote control electronic apparatus requests to transmit the remote control program of another remote control apparatus.

Abstract: An information recording disc has a connecting region formed between a parallel program recorded region containing a plurality of parallel information programs and a single program recorded region containing a single information program which is to be reproduced after one of the parallel information programs is reproduced.

Abstract: An information signal recording disc comprises a first recorded region in which an information signal at least including a video signal is recorded, and a second recorded region in which an end signal is intermittently recorded. The end signal is used to forcibly and automatically return a reproducing element of a disc reproducing apparatus from a playing position to a rest position. The second recorded region is provided at a position prior to the first recorded region in a direction of a reproducing sequence of the recorded signals on the information signal recording disc. The disc reproducing apparatus comprises a detecting circuit for detecting the reproduced end signal, and a controller. The controller controls the detecting circuit so that the detecting circuit is made substantially inoperative in a state where the disc reproducing apparatus is coupled to an external device having a discriminating function.

Abstract: A control program signal demodulating device comprises a control program demodulator for obtaining a demodulated output of a control program signal from a signal which is reproduced from a rotary recording medium which is recorded with at least the control program signal together with a video signal, where the control program signal indicates a control program including input and output commands and internal processing commands of an external device such as a computer which has a discriminating function and is coupled to a player which plays the rotary recording medium, a memory circuit for at least temporarily storing the demodulated output of the control program demodulator and producing the stored demodulated output, a selecting circuit for selectively producing data received from the memory circuit in response to a transmission request, an interface circuit for transmitting the data which is produced from the selecting circuit to the external device, and for receiving one or a plurality of control command

Abstract: Disclosed is a synchronizer for establishing synchronism between horizontal and vertical sync pulses of a non-interlaced video signal and those of an interlaced video signal, the number of non-interlaced scan lines being smaller by 2n-1 than the interlaced scan lines, where n is an integer equal to or greater than unity. Two variable frequency clocks are generated, one having a higher frequency variable as a function of a phase difference between the horizontal sync pulses of the two video signals and the other having one half the higher frequency. A first period is defined which runs from a non-interlaced horizontal sync of first occurrence in a given field to a horizontal sync of (n-1)th occurrence in the given field and a second period is defined that runs from the non-interlaced horizontal sync of first occurrence in a subsequent field to a horizontal sync of n-th occurrence in the subsequent field.
