[Problems to be Solved by the Invention] However, when attempting to apply the conventional example to the transmission of sports programs, particularly baseball broadcasts such as the Giants-Hanshin game, there were the following drawbacks.

■Since there is only one type of audio channel, it is not possible to transmit cheering voices and commentary for each team separately, and the viewer does not get a high sense of reality.

■Even if you increase the number of audio channels and transmit the cheering audio and commentary for each team, the scores that are already superimposed in the image, as well as each player's batting average, number of home runs, and ERA Character information such as career history etc. cannot be displayed for each team.

■Furthermore, even if the text information to be superimposed is transmitted as separate information and selected on the receiving side,
Both audio channel selection and superimposition selection have to be done on the receiving side, which is complicated. It was easy for viewers to get confused by looking at the paused text information, and there was a real risk that viewers would feel uncomfortable.

The present invention eliminates the drawbacks of the conventional art, receives a large number of audio and textual information, synthesizes the audio information and textual information that match the wishes of each viewer with image information, and outputs the combined image information. To provide an information transmission system capable of transmitting selection and character information without causing confusion in selection. Furthermore, a transmitting device and a receiving device for realizing the present information transmission system are provided.

[Means and effects for solving the problem] In order to solve this problem, the information transmission system of the present invention is an information transmission system that simultaneously transmits image information, multiple types of audio information, and multiple types of text information. The transmitter includes a transmitting device that correlates and transmits each audio information and text information to be transmitted, and a receiving device that switches and outputs the audio information and text information transmitted by the transmitting device according to the correspondence. , multiple types of audio information and multiple types of text information are simultaneously transmitted, and audio information and text information that match each other are output.

Furthermore, a selection means is provided for selecting whether or not to combine the character information with the image information.

Further, the transmitting device of the present invention includes a transmitting means for transmitting information including image information, and an adding means for adding a plurality of types of audio information and a plurality of types of character information to the image information in association with each other. .

Further, the receiving device of the present invention includes a receiving means for receiving information including image information, a plurality of types of audio information, and a plurality of types of textual information; and output means for separating and outputting the respective parts in correspondence with each other.

[Example] Examples of the present invention will be described in detail below.

FIG. 1 shows a transmitting device of the information transmission system of this embodiment. A video signal input from an input terminal 101 is subjected to processing such as A/D conversion and addition of an error correction code in an image processing device 104. As a result, the image signal becomes, for example, serial data as shown in FIG. 3A.

On the other hand, the audio signal input from the input terminal 102 is subjected to processing such as A/D conversion and addition of an error correction code in the audio processing device 105. Further, the audio signal input from the input terminal 103 is processed in the audio processing device 106 in the same way as the audio signal input from the input terminal 102. 1
The audio signal data that is the output of 06 is sent to the image processing device 104
is appended to the output of Figure 3B shows the data string after it has been added.

On the other hand, the character information to be superimposed on the video is converted into a predetermined code by the character information generator 109 and added to the output of the data adder 107 by the data adder 108 . Figure 3C shows the data string after it has been added,
The order of data addition is determined in advance in accordance with the content of audio data addition. A unique code may be added.

The output of the data addition device 108 is further transmitted to the synchronous addition device 1
A synchronizing signal is added by 10 to form the data string shown in FIG. 3D, which is output to the output terminal 111. The output can be transmitted in a predetermined signal form by a modem, or can be recorded on a magnetic recording medium by a magnetic recording device.

FIG. 2 shows a receiving device of the information transmission system of this embodiment.

The data shown in FIG. 3D is input to the input terminal 201. The synchronization signal in the input data is sent to the synchronization separator 20.
2 and supplied to the timing control section 206. This timing control section 206 determines the operation timing of each section of the receiving device based on the synchronization signal.

On the other hand, the image processing device 203 performs processing such as error correction and D/A conversion on the image data in the data in correspondence with the image processing device 104 on the transmitting device side, and outputs a video signal.

The character information processing devices 208 and 209 each extract character information data from a predetermined position corresponding to the output data of the synchronization separation device 202, and generate a character signal with a code corresponding to the character code of the character information generating device 109 of the transmitting device. Occur.

One of these character signals is selected by the switch 212 and inserted into a predetermined position on the screen in the mixing device 204. Thereafter, it is output from the output terminal 205 as a video signal.

In addition, if text information is not required and only audio information and image information are required, or if an image of the original material without superimposition is required, an open/close switch controlled by the controller 216 at the user's discretion. By opening 215, an image without superimposition can be obtained.

The audio processing devices 210 and 211 take out audio information data from predetermined positions corresponding to the output data of the synchronization separation device 202, respectively, and perform error correction, D/A, etc. in correspondence with the audio processing devices 105 and 106 of the transmitting device. Signal processing such as conversion is performed, and one of the signals is selected by the switch 213 and output to the audio output terminal 214.

Here, the switches 212 and 213 are operated by the operation unit 207 and are switched in conjunction with each other. That is, for example, when switch 212 is connected to terminal 212a, switch 213 is always connected to terminal 213a. In the example of a baseball broadcast, for example, text information from the Giants' side is also selected for audio of cheering and commentary from the Giants' side.

In this embodiment, the audio information and the text information are transmitted together, but the audio information and the corresponding text information may be transmitted as a pack. Further, although the case where two types of voice information and one character information are transmitted has been described, it goes without saying that the present invention can be applied to a case where three or more types of voice information are transmitted.

[Effects of the Invention] As explained above, according to the present invention, a large number of audio and textual information is received, and the audio information and textual information that match each viewer's wishes are combined with image information and output. At the same time, it is possible to provide an information transmission system that can transmit information without causing confusion in the selection of voice information and text information. Furthermore, it is possible to provide a transmitting device and a receiving device that implement the present information transmission system.

Furthermore, it is now possible to simultaneously transmit multiple pieces of audio information and multiple pieces of text information along with images, and it is now possible to select text information that corresponds to the audio information. Since it is now possible to transmit the information separately or not output text information, the video signal is not cut out by the superimposed signal, and the receiving device can obtain the original video signal. , video materials can be used for multiple purposes.
