  That is, the broadcast program sending apparatus of the present invention can easily send a complex composite event control by a TAKE operation by an operator in a system for automatically sending a news program according to an item table / cue sheet.

  In the broadcast program transmission apparatus of the present invention, NEXT control (next control) is sent to the first row material synthesis means [MK (Mix and Keying) 1] for a synthesis event that is on air (OA). It is determined whether or not it is fader value control, and in the case of fader value control, the fader value is set for the first row material synthesizing means (MK1), and the TAKE operation by the next operator performs the first row. By changing the composition state of the material composition means (MK1), it is possible to perform the material removal operation from the composite waveform and the reverse movement, which was impossible in the past.

  As described above, in the broadcast program transmitting apparatus of the present invention, the composition state of the first row material synthesizing means (MK1) is changed by the same operation as the TAKE operation for switching the materials by the second row material synthesizing means (MK2). Therefore, it is possible to perform complex composition control with a simple operation in news transmission whose operation has been diversified.

  That is, in the broadcast program transmission apparatus of the present invention, it is possible to easily perform complicated switcher control, which has been operated only by a manual operation by an operator, with the TAKE button.

  The present invention has the above-described configuration and operation, so that it is possible to perform complex composition control with a simple operation.

  Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of a broadcast program sending apparatus according to an embodiment of the present invention. In FIG. 1, a broadcast program transmission apparatus according to an embodiment of the present invention includes an automatic news transmission control apparatus 1 that performs control by a TAKE operation using an item table / cue sheet (not shown) created in advance, and a plurality of columns. The switcher device 2 has a material composition means [MK (Mix and Keying)] column. Further, the switcher device 2 includes an input material selection unit 3, a first row material synthesis unit (MK 1) 4, and a second row material synthesis unit (MK 2) 5.

  The input material selection unit 3 switches a plurality of materials input from the outside, and selects a composite material to be passed to the material synthesis unit (MK1) 4 in the first column and the material synthesis unit (MK2) 5 in the second column. The material synthesizing means (MK1) 4 in the first column mixes the materials selected by the input material selecting means 3 or performs key composition. The material synthesis unit (MK2) 5 in the second row selects the material selected by the input material selection unit 3 and the material synthesized by the material synthesis unit (MK1) 4 in the first column, and selects those materials. Mix and key composite.

  The pre-created item table / cue sheet holds control information in the automatic news transmission control device 1 before on-air (OA: On Air), and material selection control to the switcher device 2 by TAKE operation during on-air. The composition control to the material synthesis means (MK1) 4 in the first row and the material composition means (MK2) 5 in the second row is performed.

  FIG. 2 is a flowchart showing the operation of the switcher device 2 of FIG. 1, and FIG. 3 is a diagram for explaining the operation of the broadcast program sending device according to one embodiment of the present invention. The operation of the embodiment of the present invention will be described with reference to FIGS. 2 is realized by a CPU (central processing unit) (not shown) of the switcher device 2 operating a program.

  First, it is assumed that the camera 10 in FIG. 3 is on-air in the material synthesizing means (MK2) 5 in the second row. The automatic news transmission control device 1 sets the NEXT event in the MK1 column and sets the effect for transitioning to the NEXT event in the MK2 column (step S1 in FIG. 2).

  Here, the effect is a fader for fading out or appearing one image or sound slowly, a wipe (WIPE) for erasing the screen in various forms, and displaying another screen there. It shows special effects on images and sounds by the technique of.

  In the present embodiment, the camera 13 and the relay material selection instruction 13 are combined in the BASE-A and BASE-B to the input material selection means 3 in FIG. Is set in the material synthesizing means (MK1) 4 in the first column, and the effect set 11 in FIG. 3 is set in the material synthesizing means (MK2) 5 in the second column.

  Next, in order for the operator to advance the event as the program progresses, a base TAKE operation is performed on MK2 indicated by 12 in FIG. 3 (step S2 in FIG. 2). By this base TAKE operation, the material synthesizing means (MK2) 5 in the second row executes the effect 11 in FIG. 3, and then selects and sends the image 13 in FIG. 3 as on-air (step S3 in FIG. 2).

  Thereafter, the switcher device 2 determines whether or not there is a next event (step S4 in FIG. 2). Here, if there is no NEXT event, the process ends. If there is a NEXT event, it is further determined whether or not the NEXT control is a change in the fader value of the on-air event (step S5 in FIG. 2).

  Further, when it is not the on-air event fader value change control, the process returns to the NEXT event setting operation of step S1, but when it is the on-air event fader value change control, the first row material synthesis means (MK1) 4 On the other hand, the transition time indicated by the effect 14 in FIG. 3 and the fader value to the NEXT event indicated by 16 in FIG. 3 are set (step S6 in FIG. 2).

  After the setting is completed, the operator performs the fader control to the material synthesizing means (MK1) 4 in the first row by the TAKE operation 15 in FIG. 3 (step S7 in FIG. 2). Finally, the material synthesis in the first row is performed. A process of changing the composition state of the video is performed in the row of means (MK1) 4 (step S8 in FIG. 2).

  As described above, in the present embodiment, the same operation as the TAKE operation for switching the material by the material synthesizing means (MK2) 5 in the second row changes the composition state of the material synthesizing means (MK1) 4 in the first row. In news transmission whose operation has been diversified, there is an effect that complicated composition control can be performed with a simple operation.

  FIG. 4 is a block diagram showing the configuration of a broadcast program transmitting apparatus according to another embodiment of the present invention. In FIG. 4, the configuration of the broadcast program sending apparatus according to another embodiment of the present invention is that the materials selected in the MK1 column by the input material selection means 23 are BASE-A and KEY-1. This is different from the embodiment of the present invention. In the present embodiment, the composition in the material synthesizing means (MK1) 24 in the first row is also performed by the KEY composition for BASE, while the BASE-to-base wipe composition is performed in the above-described embodiment of the present invention. There are some differences.

  When the KEY composite material is created by the material composition means (MK1) 24 in the first column, whether or not the fader value change performed in the process of step S5 in FIG. By substituting for this determination, an operation different from that of the above-described embodiment of the present invention becomes possible.

  As a result, in this embodiment, the operator can easily perform the KEY state change operation with the news automatic transmission device even though the on-air progression by the same TAKE operation is possible.

  The present invention can be applied to uses such as master switcher control in a master device, and can also be applied to an automatic operation device in an information program or a production program.
