Abstract: A video signal output circuit used in a TV set to sample the frequency level of an input video signal so that monitored pictures are automatically optimized in quality. A luminance signal is separated from the input video signal by a Y/C separator. A plurality of band-pass filters whose passing frequencies are f , f , f , ..., fn detect the frequency spectrum of the luminance signal through sampling. The detected values are sent to a controller attached to an equalizer. The equalizer is controlled so that monitored pictures based on the output video signal are optimized in quality.

Abstract: In a television image display apparatus, one field of an input video signal is divided into a plurality of areas in each of which image information is sampled, and an arithmetic processor (3) provides a video control signal on the basis of preset adjusting data received from a memory and the sampled image information. Luminance, chrominance or sharpness levels can be automatically controlled for each field by such video control signal to maintain the video display in an optimum state.

Abstract: A television receiver having a CPU (central processing unit), a ROM (read only memory) in which a program and a font data are written, and a RAM (random access memory) for work area and a shift register. The font data to be indicated as a channel numeral is loaded to the shift register by an interrupt procedure and the output from the shift register is supplied to the video signal system whereby to indicate the channel numeral after the channel is changed.

Abstract: A single, hand held remote control unit produces command signals used to control all operational aspects of a video tape recorder and an associated television receiver, and the video tape recorder and television receiver include switches that upon actuation can provide various interconnections so that all operating modes of the two units are possible. Actuation of the switches is performed by controllers, arranged at the particular units, and which receive the coded command signals from the remote control unit to set the switches in accordance with any of several keys that can be actuated on the remote control unit. In one aspect, depressing a single playback key at the remote control unit will produce coded signals received by the controllers to set the television receiver to an unused channel frequency and cause the video tape recorder to reproduce a prerecorded video tape, with the reproduced signal fed to the television receiver over that unused channel for display.

Abstract: An electronic apparatus wherein a remote control signal received via a filter is decoded and, upon decision that the control signal is a power cutoff instruction, a controlling microcomputer outputs a filter control signal for actuating the filter to place the apparatus in a reception standby mode while the microcomputer itself is also set in its low power state, hence preventing a malfunction that some noise derived from external light of a fluorescent lamp or the like is recognized erroneously as a remote control signal and that the apparatus is shifted in error from the low power state to its wake-up mode. Consequently, the power consumption can be reduced in the standby mode. The remote control signal is composed of a fixed-width pulse and a succeeding control code, and upon detection of the fixed-width pulse, the controlling microcomputer is released from the low power state to wake up and then halts the operation of the filter.
