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.

摘要： An object of the present invention is to provide a multi-channel transmission system suitable for a digital broadcasting system that broadcasts television programs of many channels. Specifically, a selected one of television programs of a plurality of channels is supplied to an AV adjusting device. At this time, the selected television program is supplied to a monitor to allow recognition of its adjustment state. Since video signals and audio signals of television programs supplied from respective program supplying companies and program producing companies have different characteristics, they need to be adjusted to have common characteristics. Adjusted television programs and unselected television programs are supplied to a multiplexing section via routers.

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.
摘要翻译：时间码校正电路由用于接收输入时间码的输入电路形成; 用于存储表示时间码的数据的第一和第二存储器; 用于选择性地递增或递减要提供给第一和第二存储器的数据的加法器; 将存储在第一存储器中的数据与输入时间码进行比较的比较器; 由比较器控制的开关，用于选择性地向加法器提供输入时间码和数据开始的第二存储器; 以及输出电路，被耦合以提供第二存储器的内容作为校正的输出时间码。在从记录在磁带上的时间码轨道再现时间码的情况下，校正电路有利地适于产生连续的时间码序列，尽管在记录的时间码中出现了丢失。此外，如果在记录的时间码序列中发生跳转，则校正电路使得输出时间码以最小的信号干扰来反映这种跳跃。
