Abstract: A receiving terminal device which provides viewers with broadcasting radio waves from broadcasting stations as programs and in which, when a program switching is executed while a first program is being provided and a program is switched to a second program, the second program is provided and video recording of the first program is started, and when the program is switched back to the first program after the program is switched to the second program, the recorded first program is provided. Then, the receiving terminal device, when the first program is selected again, executes catch-up reproduction of the recorded first program in the manner that the position of recording and reproducing the first program catch up with a position in which the first program is being broadcast by the broadcasting station. Thus, even in case that a switching of a program selection is executed, a broadcasting service without failure of program contents viewing can be realized.

Abstract: A method is provided for picking up an image of an object with a camera mounted via a pan head on a moving pedestal. A reference position on a floor surface on which the moving pedestal moves and a reference angle of the moving pedestal are both set. A moving amount of the moving pedestal from the reference position and a rotation angle thereof from the reference angle are detected, and a position and an angle of the camera with respect to the object is found on the basis of the reference position, the reference angle, the moving amount and the rotation angle of the moving pedestal. Data of the position and the angle of the camera with respect to the object are transmitted to a computer for creating an image containing a real object image of the object taken with the camera.

Abstract: The display re-imaging system comprises a monitor (1) for display re-imaging and a television camera (30) having a display of the monitor for display re-imaging in a part of a field of view of the television camera. The monitor (1) consists of an LCD monitor comprising a back light (11) including cold cathode fluorescent lamps (11-1 to 11-4) as a light source having a prescribed color temperature, and a non-self-light-emitting-display panel (13) for selectively transmitting light emitted from the back light according to an image signal. The, color temperature of the cold cathode fluorescent lamps (11-1 to 11-4) is adjusted to a level corresponding to a reddish color to match with the color temperature of the re-imaging environment.

Abstract: A digital video distribution system is disclosed which includes video terminals connected within a LAN and distributes video from a certain terminal to destination terminals, simultaneously. In this system, each transmitter terminal has an encoder that converts analog video information from a corresponding video source to digitally compressed video information. A hub are connected to the video terminals to distribute digitally compressed video information from a transmitter terminal to multiple destination (receiver) terminals in accordance with a multicast communication protocol. Each of the receiver terminals has an address filter for selecting a packet from among multicast communication packets that has a desired source address as valid video information. The receiver further has a decoder for converting digitally encoded information received as valid to original analog video information with expansion.

Abstract: Transmitting and receiving apparatus, for transmitting an input video signal having 525 lines/field progressive scanning by converting the input video signal into a signal compatible with the NTSC system, and for reproducing from that NTSC-compatible signal a video signal having 525 lines/field progressive scanning. The transmitting apparatus has a first separating system for separating vertical high frequency components in a three-dimensional horizontal-vertical-temporal domain from the input video signal; a modulating system for modulating the separated components from the first separating system by .mu.-modulation; a system for filtering a modulation output from the modulating system to remove a lower sideband component from the modulation output, the filtering system having a Nyquist characteristic; and a system for multiplexing a filtered output from the filtering system to form the NTSC-compatible signal.

Abstract: In a wide-aspect television system, apparatus is provided for producing a source television signal for a wide aspect television screen, which source signal has the same horizontal and vertical synchronizing frequencies, but fewer effective scanning lines than a conventional television system. The wideaspect television system further includes apparatus for expanding the time base of the mentioned source television signal in the horizontal direction by a predetermined ratio. Further included is an apparatus for receiving a time base-expanded television signal produced by the expanding apparatus for arranging video information of both side areas of a time base-expanded television signal into top and bottom added scanning lines. A remaining area of the time base-expanded television signal substracted by both mentioned side areas have a horizontal scanning period substantially equal to a horizontal scanning period of the conventional television system.

Abstract: A television video signal synchronizing apparatus, which synchronizes an input television video signal to a reference timing mark. The input video signal is digitized and stored in a memory at locations which are provided by a writing address generator. The writing operation is performed in synchronism with the input video signal. A reading address generator produces reading addresses for reading out the stored video signal to deliver an output television signal which is synchronized to the reference timing mark. The reading address generator is controlled to read out an active video portion of the stored video signal after a delay of about one horizontal scanning period (63.5 microseconds in the NTSC system) immediately after the writing operation of the same active video portion. Thereby "lip lag" i.e. a mismatch between the audio and video signals, is avoided.

Abstract: A television strobe effects system is described in which a position information signal representing the position of a moving object included in a television picture is extracted from either the input video signal or the sample-to-sample comparison between successive frames or fields of the input video signal. The write-in of the input video signal in a picture memory is controlled in response to the position information signal so that such write-in for each frame of the input video signal is prohibited at those addresses of the memory which correspond to the position of the moving object.

Abstract: An improved phase locking system in which an independently reproduced video signal is coded into a digitized video signal in response to a first clock pulse train, the first clock pulse train being produced from a synchronizing signal and/or a color burst signal contained in the video signal. The digitized video signal is stored and storage location as well as delay prior to storage is controlled in response to the phase difference between the synchronizing signal and a reference signal. The improved phase locking system reduces the frequency of occurence of visual shifts on the reproduced television picture.

Abstract: A noise reduction system for improving the signal-to-noise ratio of a color television signal wherein a first television frame portion is recursively added to an immediately subsequent second television frame portion and the addition apparatus is controlled in response to the signal level difference between said first and second frame portions.

Abstract: A memory write-in control system provides for each dot a plurality of color designating bits representing color information for the dot as well as a set of mask command bits corresponding to the respective color designating bits. The memory content is changed in accordance with the color designating bits only when the mask command bits are at one logic level. The memory bit content is unchanged when the mask command bits are at the other logic level irrespective of the color designating bits.

Abstract: A method and apparatus for making monocolor prints in a desired color wherein a web of photoconductive material is supplied as a photosensitive material, a desired length of segment is sheared from said web of photoconductive material, said material segment is electrically charged, the charged material is exposed by a phototypesetting machine to light through desired characters, numerals and/or other symbols in an original plate of said machine, and said exposed material is developed by the use of electrophotographic toner having a desired color.
