Abstract: The present invention provides an information recording/reproducing apparatus capable of satisfying efficient use of storage capacity of a recording medium and a demand for higher picture quality of the user. An information recording/reproducing apparatus 100 has: a TV receiver 101 for receiving contents data; an input processor 103 for obtaining contents data from the outside; a DVD drive 102 for obtaining contents data from a DVD 20; a recording rate determining unit 110 for pre-setting a recording rate indicative of an information amount to be recorded per unit picture information, which is switched with lapse of time at the time of recording the obtained contents data; and a system controller 115 for recording the obtained contents data into a data storage 106 on the basis of the set recording rate.

Abstract: A recording medium playing apparatus allows an arbitrary and easy selection and reproduction of each information piece of a recording medium carrying a plurality of information pieces which variously represent a scene on the same time axis position during reproduction of information. In the recording medium playing apparatus for playing a recording medium on which same-time information groups each formed by a plurality of information pieces of the same time position are recorded, reproducing means for reproducing information of the recording medium reproduces information of the recording medium by arbitrarily selecting each information piece of the recording medium based on a command for reproducing each same-time information group.

Abstract: A stereoscopic image displaying apparatus includes: field switching signal generating unit for generating a field switching signal alternately indicating odd field periods and even field periods from an original picture signal; delaying unit for delaying the original picture signal and producing a delayed picture signal; stereoscopic image signal generating unit for alternately selecting one of the original picture signal and the delayed picture signal in accordance with the field switching signal to generate a stereoscopic image signal; and display unit for displaying the stereoscopic image signal by alternately supplying pictures of the original picture signal to one eye of a user and pictures of the delayed picture signal to the other eye of the user on the basis of the field switching signal.

Abstract: A method of searching for blanks in a digital tape player with reduced search time by performing the operation of searching for blanks on both sides of an analog recorded tape concurrently. In a digital tape player dedicated to both analog and digital reverse playback, a reverse fixed head component is arranged so that a tape can travel both ways by reversing the fixed head component 1. The head surface of the head component is divided into two tracks and one of the tracks is provided with analog playback head sections 2 and the other track with digital playback head sections 3. In such a digital tape player, analog recorded signals on one of the tracks of the analog recorded tape are being read by the analog playback head sections 2, while analog recorded signals on the other track are being read by the digital playback head sections 3 at the same time, so that blanks on both upper and lower tracks can be searched simultaneously.

Abstract: A video mixing apparatus mixes a graphics video image and a playback video image at a plurality of mixture ratios in one image plane. Fade data indicative of the mixing ratio of at least one line of the playback video signal and the graphics video signal is sequentially generated in accordance with a predetermined order. The fade data is held into holding means and is outputted from the holding means synchronously with a horizontal sync signal. The levels of the playback video signal and the graphics video signal are individually adjusted in accordance with the fade data outputted from the holding means and the adjusted signals are added. The playback video signal and the graphics video signal are mixed at the mixing ratio set every line of one image plane.

Abstract: In a stereo sound digital recording system in which a plurality of tunes or programs are sequentially and digitally recorded on a magnetic tape, the left and right analog input signals are combined and converted to a digital signal. The analog input signals are also applied to a detector which detects the head of the program or tune and which causes to be generated a start identification sub-code signal which is automatically added to the digital signal, before the modulation thereof, and which is recorded on the tape for about nine seconds in the non-sound portion preceding the tune or program. A second sub-code signal, in the form of a program number signal, may also be added to the digital signal, simultaneously with the program start identification sub-code signal, to provide recorded numbers respectively identifying programs which are sequentially recorded on the tape.

Abstract: A data recording method and apparatus for a magnetic recording medium, such as a magnetic tape for an R-DAT, in which the tops of the various music selections recorded on the tape are accurately detected so that reproduction can be started accurately. In one embodiment of the invention, program top detecting codes are recorded on the tape a predetermined time prior to the actual start of the music programs. In another embodiment, the program top detecting codes are recorded at the start of the respective programs. In the latter case, in a high speed search operation to find a desired music piece, when a corresponding program top code is detected, the commencement of reproducing the desired music piece is delayed for a predetermined period of time from the detection of the program top code, so that the reproduction is accurately carried out from the top of the desired music piece.

Abstract: In a signal reproducing device such as an R-DAT video tape recorder, a digital signal recorded on the recording medium is reproduced by the magnetic head, stored in a memory, processed by a processing circuit, and converted into an analog signal by a D/A converter, and a detector detects whether or not the reproduction signal outputted by the head is present so that, according to the output of the detector, a muting circuit mutes the digital-to-analog converted signal and a driver suspends the operation of a level meter adapted to display the level of the digital signal, whereby the production of noise signals and the abnormal display of signal levels are prevented.

Abstract: A signal recording/reproducing apparatus having both bar-type and numeric signal-level displaying units which can be easily read. The apparatus includes a sample-and-hold circuit for sampling and holding an input signal at a first predetermined rate, a first display unit for displaying in bar form the sample values sampled by the sample-and-hold circuit, a data holding circuit for sampling and holding the sample values periodically at a second predetermined rate, and a second display unit for numerically displaying the sample values selected by the data holding circuit. The bar code display can change at a rapid rate to dynamically follow the input signal, while the numeric display changes at a slower rate so as to allow the user sufficient time to comprehend the numerically displayed value.
