Abstract

PROBLEM TO BE SOLVED: To provide a system where a viewer can automatically view a broadcast with Japanese caption on TV by a sub-sound when the program is a foreign language movie broadcast. SOLUTION: In the case that a received program is a foreign movie broadcast or the like, a control section 1 distributes the broadcast into a video signal, the main sound in Japanese language and a sub-sound in a foreign language broadcast, and the control section 1 controls a TV signal and selects the main and the sub-sound under the operation of an operation section 5. A character converter 3 that recognizes the sound signal and converts it into a character and a video composer 4 that composites a video signal of the TV broadcast with the character converted by the character converter 3 are provided for the main channel where the main sound is transmitted. The foreign language sub-sound is transmitted through the sub-channel. When the sub-channel is selected, a video image with Japanese caption is automatically composited on the main channel.

2. Description of the Related Art Generally, a viewer of a TV broadcast of a foreign movie or the like watches the main channel voice dubbed by a Japanese voice actor. This has the advantage that you can easily watch foreign movies, but like in movie theaters and videos, you can listen to the live voices of the performers and understand the contents of the dialogue in Japanese subtitles. It is one of the pleasures of the viewer. For this reason, text broadcasting is used in which text information is multiplexed and broadcast on television broadcast waves in the form of codes, and a text information screen is reproduced by a text generator built in a decoder of a receiver and displayed on a CRT. . JP-A-4-2286
Discloses a television receiver that has a function of receiving and demodulating audio multiplex broadcasting and text broadcasting, and that displays subtitles when subtitle broadcasting is being performed when sub-audio is selected. However, not all programs have Japanese subtitles, and some have no subtitles. As a method of utilizing bilingual broadcasting for language learning, the value of inserting Japanese subtitles is great. For example, in Japanese Patent Laid-Open No. 5-176232 and Japanese Utility Model Laid-Open No. 6-7372, audio information is converted from audio / video information to text information. And an apparatus for superimposing on video information.

A main channel of a baseband audio band, and sub-channels and control channels are arranged in a higher frequency band. Have been. In dual sound broadcasting, different sounds are sent for the main channel and the sub channel. For example, in a foreign movie broadcast, a Japanese language broadcast as a main sound is mainly transmitted to a main channel, and a foreign language broadcast as a sub sound is transmitted to a sub-channel. A signal for automatically discriminating between a stereo broadcast and a double audio broadcast to which the present invention relates is sent to the control channel. On the receiver side of the above television audio multiplex broadcast, first, a 4.5 MHz higher audio signal is separated from the video carrier, and further, the main audio signal and the sub audio signal are separated and demodulated, and the audio signal of any of the main and sub channels is converted. Also has a circuit configuration that can be selected and received. SUMMARY OF THE INVENTION It is an object of the present invention to provide a system that allows a viewer to automatically watch a broadcast with Japanese subtitles by a simple operation of merely selecting a sub-audio. In addition, when the user wants to watch with a dubbed voice as before, this can be realized by selecting the main voice.

The operation of the present embodiment will be described with reference to FIG. 1. The TV signal is distributed to a video signal, a main audio signal, and a sub audio signal by the control unit 1. Information that the viewer has selected the main sound or the sub sound with the operation unit 5 is sent to the control unit 1. When the viewer selects the sub-audio, the main audio signal is subjected to voice recognition in the character conversion device 3, is further transcribed, and is sent to the video synthesizing device 4. The video signal is sent from the control unit 2 to the video synthesizing device 4. The image synthesizing device 4 synthesizes the image signal and the character converted by the character converting device 3 and sends the signal to the display device. The sub audio signal is sent to the display device as it is. Even when the viewer selects a sub-audio and selects a foreign language broadcast, if it is not necessary to synthesize a character pattern with the video signal, the video signal is directly transmitted to the display device 6 under the control of the control unit 2. Can be If the viewer selects the primary audio,
The main audio signal is sent to the display device 6 without being converted or synthesized by the character converter 3 and the video synthesizer 4. The video signal is also sent to the display device 6 by the control unit 2. The sub audio signal is not transmitted to the display device 6.
