In order to ensure a reliable signal source for the nonprogram type information the apparatus has a controller for setting the channel tuner to the proper channel and selecting the proper signal source to receive the nonprogram type information when the apparatus is not used for receiving regular programming signals selected by the viewer.

Abstract: In digital VTR's, a change in levels and frequency response in the VTR analog circuits or analog transmission paths causes a problem of deterioration in the video picture quality due to quantization distortion when dubbing is repeated based on an analog video signal. In order to solve this problem, according to the present invention, a level reference signal is superposed as a predetermined digital value on an output video signal of the reproducer, then based on the reference signal, the level and the frequency response of the analog transmission path are corrected in the recorder. Thus, dubbing can be achieved by using digital VTR's without any influence of quantization distortion.

Abstract: A method and apparatus for controlling a VCR or other television program recording device for unattended recording of television programs based upon user selections from an on-line television program schedule system, converts the on-line television schedule listings for the user selected programs into event timer information and loads the event timer information into an event timer. The event timer, which may be located in the VCR or external to the VCR, controls the VCR for unattended recording in the customary manner. Since the VCR is controlled by the event timer information, rather than directly from the on-line program schedule listings, the VCR may be controlled for unattended recording even if the on-line listings are lost. Accordingly, the on-line listings may be stored in low cost volatile memory (dynamic RAM). Only the event timer information should be stored in non-volatile memory (static RAM), which can be kept small due to the limited information contained in the event timer information.

Abstract: In a CS broadcast receiving system, when a station is to be selected, an AFC process is first performed with the frequency in the tuning circuit adjusted in units of a coarse frequency adjustment value for reception of a CS television broadcast signal. When a receive signal to be selected by the tuning circuit is not the CS television broadcast signal, the AFC process is performed with the frequency in the turning circuit adjusted in units of a fine frequency adjustment value for reception of a CS.With this arrangement, it is made possible to increase the tuning accuracy when tuning in to the CS sound broadcast signal, while the time required for tuning is shortened and the waiting time reduced when tuning in to the CS television broadcast signal and, thereby, both the requirements for reception of the CS sound broadcast signal and for reception of the CS television signal can be satisfied.

A display is provided for simultaneously displaying at least a part of a video image which corresponds to the first video signal, and also for displaying a state of the multiplexing operation being performed by the multiplexing circuitry under the control of the control circuitry. Preferably, only a peripheral portion of the image is faded in the view finder. Alternatively, a bar graph on the side of the image in the view finder indicates the degree of fading the image is subjected to.

Thereby, mutual beat interference between the plurality of tuners is eliminated.

The respective channels are sampled at approximately one frame per second per channel for approximately 2 hours, thereby providing a full resolution extended time recording capability.

Abstract: A dual HDTV/NTSC receiver includes a microprocessor for controlling a tuner for synthesizing the carrier frequencies of HDTV signals and NTSC signals. The HDTV signals are inherently of much lower power than the NTSC signals. The tuner initially synthesizes the carrier frequency of a desired HDTV signal which is attempted to be detected in an narrow band synchronous detector. Detection of the HDTV signal produces a high lock detect signal which causes the microprocessor to enable an HDTV processing channel. If no HDTV signal is detected, the lock detect signal remains low and the microprocessor controls the tuner for synthesizing the carrier frequency of the NTSC co-channel television signal. A high lock detect signal from the narrow band synchronous detector, indicating detection of the NTSC co-channel causes the microprocessor to enable the NTSC processing channel. A system for automatically programming the receiver and memorizing which type signal is present on each television channel is also shown.

Abstract: Sixty-four regions are established on an image sensed picture from a video camera, where each evaluating value r.sub.ij, b.sub.ij, and y.sub.ij is obtained by averaging color difference signals R-Y and B-Y and luminance signal Y obtained from an image sensed signal over 1 field period for each region. When determination is made that luminance evaluating value y.sub.ij out of these evaluating values exceeds a predetermined value, the color evaluating values of the corresponding region are attenuated by a predetermined amount, in response to gain control signals derived from the color difference signals. As a result, the effect of an object of high luminance towards white balance adjustment is reduced.

Abstract: Many sensor information processing applications currently use monochrome B-scan presentations to exhibit processing results from radar, sonar, spectral estimation, seismic profiling, radio astronomy, bio-engineering, and infrared imaging. The use of color for such raster display presentations have been limited to the coding of amplitude values for a fixed set of hue/luminance colors to convey recognition by the human operator. Hue and luminance are used here independently to convey two orthogonal pieces of low signal-to-noise sensor information simultaneously to the operator for quick and accurate recognition. The net result is an added degree of freedom available on a single display surface, which not only improves operator recognition and reaction time for critical events, but precludes the necessity of a second display presentation for the alternate information and subsequent correlation of two data sets by visual comparison.
