DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video transmitting apparatus, and more particularly to a video transmitting apparatus that records a plurality of video materials on a recording medium and sequentially transmits the recorded video materials in accordance with an instruction of a transmission list.

[0002]

2. Description of the Related Art FIG. 4 is a block diagram showing an example of a conventional video transmitting apparatus. In the figure, a video material signal input via a video material input terminal 31 is
And recorded on a recording medium such as an internal magnetic disk, optical disk, or magnetic tape. On the other hand, the data input unit 3
Reference numeral 3 denotes input of transmission data indicating the order in which the video material recorded on the recording medium in the video recording / reproducing section 32 is output, and the result is recorded in the transmission list section 34. Since the recorded video material is managed by being assigned an ID number, it is recorded in the transmission list unit 34 in the order in which the ID numbers are transmitted.

[0003] When the transmission data is prepared in the transmission list section 34, the control section 36 takes in the first transmission data of the transmission list section 34. Here, when the control unit 36 fetches the leading data from the sending list unit 34, the control unit 36 deletes the fetched sending data from the sending list unit 34 and always replaces the next sending data with the leading data.

The transmission operation unit 35 is provided with a so-called “take (T)
AKE) control ”and“ Next Change (NEXT C)
HANGE control), which is used by the operator to perform an operation of selecting and instructing either control at any time, and is composed of a push button or the like. When the operation is performed, the transmission operation unit 35 transmits the NEXT CHG to the control unit 36.
Make instructions.

In response to the NEXT CHG instruction, the control unit 36 controls the video recording so that the head video of the video material corresponding to the head transmission data (ID number) is output from the video recording / reproducing unit 32 from the transmission list unit 34. It controls the playback unit 32. That is, the standby state is set so that the video material corresponding to the transmission data at the head of the transmission list section 34 can be transmitted.

Next, when a take control (hereinafter referred to as TAKE) operation is performed by the transmission operation unit 35, the transmission operation unit 35 issues a TAKE instruction to the control unit 36. The control unit 36 instructs the video recording and reproducing unit 32 to reproduce the standby video material by the TAKE instruction.
The video recording / reproducing unit 32 reproduces the instructed video material and outputs it to the output terminal 37. When the video material has been reproduced, the reproduction is stopped. Thereafter, the control unit 36 captures the first transmission data of the transmission list unit 34 (that is, the next transmission data replaced first). This TAKE is not executed unless the video material transmitted by the video recording / reproducing unit 32 is on standby.

The above operations are summarized as follows.
The order of the video materials to be transmitted is input as a list from the data input unit 33 to the transmission list unit 34. Sending operation unit 35
The NEXT CHG operation causes the control unit 36 to set the first video material of the video recording / playback unit 32 to the transmission standby. By the TAKE operation by the transmission operation unit 35, the first video material that has been on standby is transmitted from the video recording / reproducing unit 32. After the transmission of the first video material, the video recording / reproducing unit 32 stops operating.

Next, the NEXT C by the transmission operation unit 35
By the HG operation, the control unit 36 sets the second video material of the video recording / reproducing unit 32 to the transmission standby. Sending operation unit 35
, The second video material that has been on standby is transmitted from the video recording / reproducing unit 32. Hereinafter, by repeating the above operation, the video material is sequentially transmitted from the video recording / reproducing unit 32.

[0009]

However, in the above-mentioned conventional video transmitting apparatus, since there is only one video recording / reproducing section 32, only the video in the transmission standby mode or the video being transmitted is obtained from the video recording / reproducing section 32. Can not do. For this reason, in operation, it is not possible to confirm the first video of the next video in advance.

If the video recording / reproducing section 32 has two outputs, the above problem can be avoided. However, when such a video recording / reproducing section is used, the data input section 33, the transmission list section 34, the transmission operation section 35 , Two control units 36 are also provided.
It is necessary to use an independent video transmission device, and it is practical to use two independent video transmission devices only to check the first video of the next video in advance. Not wasteful.

[0011] The present invention has been made in view of the above points,
By obtaining the transmission video and the first video of the video material to be transmitted next from one output of the video recording / reproducing unit, by indicating the content of the video material to be transmitted next to the operator,

After controlling the video recording / reproducing unit to the standby state for sending the first video material, the video signal output from the video recording / reproducing unit in the standby state is the first video material. When the first memory is controlled to pass through the memory and the second transmission control operation is performed by the transmission operation means,
The video recording / reproducing unit is controlled to reproduce the video signal of the first video material in the standby state from the recording medium, and the reproduced video signal of the first video material passes through the first memory. Control means for controlling the first memory, wherein the video signal from the first memory is transmitted to the first output terminal as a video signal of the video material to be transmitted, and the video signal from the second memory is transmitted to the next output terminal. The video signal is transmitted to the second output terminal as a video signal of the video material to be transmitted to the second output terminal.

The present invention further comprises a switching unit for switching a transmission path between the first and second output terminals of the output signal of the first memory and the output signal of the second memory. Controls the switching unit to switch from the previous transmission path to the other transmission path when the first transmission control operation is performed after the second transmission control operation is performed by the transmission operation means. And the second video material transmitted first stored in the transmission list storage means and the third video material transmitted next
The video recording / reproducing unit is controlled so as to reproduce the first video signal of the third video material based on the transmission order of the third video material, and the first video signal of the reproduced third video material is converted to the first video signal.

The video recording / reproducing unit is controlled in the standby state for transmitting the second video material, and the video signal output from the video recording / reproducing unit in the standby state passes through the second memory and is input to the switching unit. 2 is controlled.

According to the present invention, a video recording / reproducing apparatus having only one output terminal by the first transmission control operation is used to control the head of the second video material to be transmitted later out of the two video materials transmitted continuously. Since the video signal is transmitted first and written to the second memory, and then the first video material to be transmitted first is controlled to the transmission standby state, the second memory is repeatedly read out. The first video signal of the second video material to be transmitted next can be transmitted to the second output terminal. Also, by the second transmission control operation, the video signal of the first video material to be transmitted first, which was in the standby state, is transmitted and output to the first output terminal through the first memory. The video signal of the video material to be transmitted first can be transmitted to the first output terminal.

Further, when the first transmission control operation is performed thereafter, the switching unit is controlled to switch from the previous transmission path to the other transmission path, and the video recording / reproducing apparatus is continuously transmitted. The first video signal of the third video material to be transmitted later of the two video materials to be transmitted is first transmitted and written into the first memory, and then the transmission standby of the second video material to be transmitted first is performed. Since the state is controlled, the first video signal of the third video material to be transmitted next can be transmitted to the second output terminal through the switching unit by repeatedly setting the first memory to the read state.

[0016]

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a video transmission device according to the present invention. In the figure,
