Description

  The present invention relates to a broadcast time display system that displays a remaining broadcast time of a program between studios of a broadcast station, and a display control method thereof.

  In broadcasting stations, when broadcasting live broadcasts from the main station studio and local station studio, or from a relay car, etc. in news programs, for example, announcers and directors in each studio with the timing of broadcast switching from the relay car, for example. And broadcast equipment operators. This switching timing is different from broadcast program switching at a predetermined time, and is performed at a timely and delicate timing. Therefore, there is a cue (start signal) between the relay vehicle and the relay site camera at the top of the camera. A device is provided such as providing a display to notify the announcer or cameraman of timing (for example, Patent Document 1).

  Still further, there may be a case where an announcer is responded, a standby time (remaining time) display such as camera signal switching is performed until a cue is issued. However, for example, when a program is switched between a master station studio and a relay destination such as a relay car, there is a delay in the communication line for the notification signal of the remaining time from the main station to the relay car to the queue. The switching timing cannot be accurately notified from the station side to the relay vehicle. In particular, when performing satellite relay or live relay with overseas, troubles due to transmission delay are remarkable, so in signal switching that requires timing such as several tens of milliseconds, camera signal switching does not depend on a queue, There was a problem that the standby operation was inadequate, such as observing the camera signal on a monitor, and manually observing that the signal being switched by the operator was switched manually.

Also, if the transmission delay time via satellite etc. becomes 0.1 seconds or more, the receiver will detect the delay in the voice and the operation on the screen, and the broadcast reception is smooth after receiving the queue. There are some problems that do not become.

The transmission unit 3 is a communication unit that transmits a remaining time notification signal from the command unit 1 to the remote display unit 2, and uses a dedicated line, a public line, or the like by various communication media such as optical communication and satellite communication.

2 and 3 are block diagrams showing functional configurations of the command unit 1 and the remote display unit 2 in FIG. 1, respectively.
In FIG. 2, the command unit 1 includes, for example, a standard clock 11, a queue setting unit 12, a calculation unit 13, and a transmission unit 14 that are installed on a control console of a main station studio and connected to each other via an internal bus or the like. Yes. The standard clock 11 is a high-precision clock using time information such as JJY or GPS, and is synchronized with a standard clock 21 provided in the remote display 2 described later, and outputs the time information to the calculation unit 13 via an internal bus. is doing.

  The queue setting unit 12 is an input means that includes a command button 121, a keyboard that is not displayed, a dial, and the like, and sets and inputs a standby time (remaining time trc) until the main station operator puts out the queue. The data of the remaining time trc set and input is output to the calculation unit 13 via the internal bus.

  The calculation unit 13 monitors time information input from the standard clock 11, calculates the queue time tc from the remaining time trc input from the queue setting unit 12, and outputs it to the transmission unit 14 via the internal bus. The transmission unit 14 transmits the input queue time to the remote display unit 2 via the transmission unit 3. The transmission destination of the queue time tc transmitted from the transmission unit 13 is set in the transmission unit 3 which is a communication line connected to the relay destination.

  In FIG. 3, the remote display unit 2 includes, for example, a standard clock 21, a queue display unit 22, a calculation unit 23, and a reception unit 24 which are installed on a control console of a local station studio and connected to each other via an internal bus. ing. The standard clock 21 is a high-precision clock using time information such as JJY or GPS, and is synchronized with the standard clock 11 provided in the command unit 1 and outputs the time information to the calculation unit 23 via the internal bus. .

  The reception unit 24 outputs the queue time tc received via the transmission unit 3 to the calculation unit 23 via the internal bus. The calculation unit 23 obtains the difference between the queue time tc and the time information input from the standard clock 21, and outputs the remaining time until the queue time tc and the standby time tcr to the queue display unit 22 through the internal bus every moment. To do.

  The queue display unit 22 displays the input standby time tcr, and an operator such as an announcer or a cameraman performs a required standby or broadcast work.

FIG. 4 is a flowchart for explaining the operation procedure of the broadcast time display system according to the embodiment of the present invention.
The operation procedure of the broadcast time display system will be described below with reference to the functional block diagrams of FIGS. 2 and 3 and the flowchart of FIG.

  Now, in the main station, it is assumed that an announcer is reading a news manuscript in a news program, and an event is being broadcast that an overseas branch that is introduced in the news program is being relayed on site. The operator of the master station determines that switching to the on-site relay will be performed 20 seconds after the announcer reads out the document, and sets 20 seconds with the keyboard (not shown) of the queue setting unit 12 of the command unit 1 (step s1). The command button 121 is pressed down.

  When the calculation unit 13 receives 20 seconds as the remaining time tcr from the queue setting unit 12, the calculation unit 13 inputs time information from the standard clock 11 (step s2). If the current time is, for example, 12:10:10, 02, the queue time tc is output to the transmitter 14 as 12:10:20, 20 seconds later (step s3). When the transmission unit 14 transmits the cue time tc to the transmission unit 3 (step s4), at the relay site of the overseas branch office, the reception unit 24 of the remote display unit 2 installed in the relay vehicle transmits the transmission unit via a satellite line or the like. 3 receives the queue time tc (step s5).

  The receiving unit 24 outputs the received queue time tc to the calculating unit 23 via the internal bus (step s6). When the cue time tc is input, the calculation unit 23 reads time information from the standard clock 21 every moment thereafter (step s7), obtains a difference from the cue time tc, and the remaining time trr at the overseas branch side. Is calculated (step s8), and is output to the cue display unit 22 momentarily (step s9).

  Assuming that the propagation delay time is 0.15 seconds because the calculation unit 23 receives the cue time tc via a satellite line or the like, the first reception time of the cue time is 12:00 at the transmission time of the main station. 10 minutes 10 seconds 17 Accordingly, the remaining time trr of 19.83 seconds is first displayed on the queue display unit 22, and thereafter, the remaining time is displayed in a reduced manner.

  An announcer or a cameraman can monitor the remaining time display, perform voice and camera signal switching processing at a timing of 1 second or less, and can smoothly advance the screen and the program.

  Further, at the time when the remaining time becomes “0”, the cue display unit 22 displays a cue (cue), and further has a function of outputting a switching signal, such as a camera signal of several tens of milliseconds or less. It may be used for switching.

  In the above description, the remaining time is notified from the main station to the relay vehicle or the like, but conversely, the remaining time may be transmitted from the relay vehicle or the like to the main station.

  As described above, according to the present invention, it is possible to accurately display the remaining time of program switching without being affected by the occurrence of a delay time or the like occurring in the transmission path.
