    摘要: Provided is a network system which is capable of smooth remote control of appliances in a household while improving the security. A household server for controlling home appliances and an external server for mediating between the household server and a user terminal are set on an Internet. The household server gives a right to access only to the external server that is registered in advance. When accessed by the user terminal, the external server performs user authentication and, if the access is authenticated as from an authorized user, specifies which household server is to be used by the user, and makes an access request to the corresponding server. The household server checks whether the access request is valid or not and, when the access request is found as a result to be valid, allows the user terminal to input a control instruction through the intermediation of the external server.

    摘要: An optical disc and an optical disc drive for the optical disc are provided which are suitable for recording data with a high density. The optical disc D uses both lands and grooves as recording tracks. Each of the tracks consists of one address segment and forty five data segments. The address segment is wobbled at one side thereof. Each of the data segments is a DC groove. The address segment records an address information including a sync signal, frame address, track address and CRC, a tilt pattern and a clock mark. The clock mark is adapted to reflect laser beam in one amount before the mark and in another amount after the mark. The tilt pattern has a different track pitch from those in other areas. The data segments record data magneto-optically.

    摘要: An FM-MUSE signal and a pilot signal are frequency-multiplexed, to be recorded on a video disc (D). In addition, a clamp level signal and an index signal are multiplexed on particular lines of a plurality of lines of the MUSE signal. The index signal is detected from the FM-MUSE signal reproduced from the video disc by a video disc player (100). Pulses of the reproduced pilot signal are counted, beginning at the time of this detection. Accordingly, the timing of generating the clamp level signal is specified, so that clamp pulses are generated. A clamping circuit (5) is provided in the video disc player, so that the clamp level signal is accurately clamped in response to the clamp pulse.

    摘要: Two recording tracks (T1) and (T2) are formed in parallel with each other on a stereoscopic video disc record (D). Image information for a right eye and audio information are serially recorded on one recording track (T1). Image information for a left eye and audio information are serially recorded on the recording track (T2) at a synchronized timing with the image information for a right eye and the audio information recorded on the adjacent recording track T1. Information can be easily recorded on such steroscopic video disc record (D) in a manner that the image information for right and left eyes and the audio information are recorded at the same time by two recording beams. On the other hand, stereoscopic image information can be reproduced by reproducing respective recording tracks at the same time by two reproducing means. Furthermore, a normal two dimensional image information can be reproduced by reproducing either one of the recording tracks serially by one reproducing beam.

    摘要: A frequency multiplexing circuit in an optical video disc recorder frequency-multiplexes a second signal comprising a digital sound signal on the low frequency band of a first signal comprising a frequency-modulated video signal to generate a recording signal. In addition, the recording signal is applied to a limiter to be limited. In this case, a noise component produced in a band of the second signal is extracted by using a Bessel filter and a subtractor and previously subtracted from the recording signal generated by frequency multiplexing. The recording signal including a negative noise component is applied to the limiter, so that harmonic noise and linear distortion noise essentially produced in an output of the limiter can be cancelled. Furthermore, a slice level of the limiter is suitably adjusted, so that asymmetrical noise in the output of the limiter can be also eliminated.
