    摘要: In a video signal recording apparatus, information about a video commercial program or message (CM) is recorded in the vertical blanking interval (VBI) of the video signal constituting the commercial message so that the information remains with the commercial program or message even during subsequent editing. Video signals representing a plurality of commercial messages and having respective information in the vertical blanking intervals are serially recorded on a master tape while generating stop code data and recording the stop codes in a longitudinal track on the master tape. Further, a video signal reproducing apparatus is described which can extract data from the VBI and longitudinal track of a tape, process the data and automatically terminate the reproduction after reproducing a stop code.

    摘要: An input/output switching apparatus which can construct the system more flexibly as compared with the conventional system. The input/output switching apparatus is configured so that a user can manage the connection state of a physically-existing switching unit as the connection state of a virtual switching unit which corresponds to the physically-existing switching unit. Thus, the user can control the physical switching unit merely by operating the virtual switching unit which is constructed so as to be convenient for operation.

    摘要: A time code correction circuit is formed of an input circuit for receiving an input time code; first and second memories for storing data representing the time code; an adder for selectively incrementing or decrementing data to be supplied to the first and second memories; a comparator comparing the data stored in the first memory with the input time code; a switch controlled by the comparator for selectively supplying the adder with the input time code and the data started second memory; and an output circuit coupled to provide the contents of the second memory as a corrected output time code. Where the time code is reproduced from a time code track recorded on a magnetic tape, the correction circuit is favorably adapted to produce a continuous time code sequence despite dropout in the recorded time code. Also, if a jump occurs in the recorded time code sequence, the correction circuit causes the output time code to reflect such jump with a minimum of signal disturbance.

    摘要: A matrix switching apparatus includes a plurality of switching units connected in tandem, each switching unit having a plurality of input terminals and a plurality of output terminals. There are a plurality of transmission/reception units, each provided within a respective switching unit and also within a remote control unit. The transmission/reception units are for transmitting switching data. A first one of the transmission/reception units is set to a master station mode and sequentially polls the remaining transmission/reception units which are set to a slave station mode. The remaining units respond to the polling by outputting switching data, which is collectively transmitted by the master station over a serial busline. The remaining transmission/reception units receive only relevant data from the switching data transmitted over the serial busline and supply the relevant data to controlling units which control the turning on and off of crosspoint switches in the switching units.
