In addition to displaying and outputting audio corresponding to the video from the speaker 12, an explanatory note (for example, corresponding Japanese translation) of a word (for example, English word) designated by the user in the subtitle character string is displayed on the video. It is superimposed and displayed on the display 11.

In the DVD player, the operation input section 1 including a remote controller and buttons provided on the main body accepts a user's operation and outputs the operation information to the control section 2. The control unit 2 reads the control program recorded on the recording medium 3 and controls the entire DVD player in accordance with the user's operation information input from the operation input unit 1 based on the read control program. To do.

For example, the control unit 2 selects the word of the character string of the subtitle and responds to the information of the operation by the user to decide,
Get the description of the word from the dictionary database 13
The explanation of the word is supplied to the OSD unit 10 and is displayed on the image in a superimposed manner. The recording medium 3 is a magnetic disk (including a floppy disk), an optical disk (CD-ROM (Com
pact Disc-Read Only Memory), DVD (Digital Versatile
Disc)), a magneto-optical disc (including MD (Mini Disc)), or a semiconductor memory.

The reading section 5 outputs a data stream including video data, audio data, and caption data to the DVD 4
Read out and output to the demultiplexer (DEMUX) 6. The demultiplexer 6 separates the data stream input from the reading unit 5 into video data, audio data, and subtitle data, and the video decoder 7,
It is output to the audio decoder 8 or the subtitle decoder 9.

The video decoder 7 decodes the video data encoded by the MPEG2 system, for example, and outputs the obtained video signal to the OSD section 10. Audio decoder 8
For example, the audio data encoded by the MPEG2 system is decoded, and the obtained audio signal is output to the speaker 12. The subtitle decoder 9 decodes the encoded subtitle data and outputs the obtained subtitle signal (including characters to be displayed, display position, display timing, erasing timing, etc.) to the control unit 2 and the OSD unit 10.

The OSD (On Screen Display) unit 10 receives from the video decoder 7 a subtitle character string included in the subtitle signal input from the subtitle decoder 9 and an explanatory text of a word input from the control unit 2. And outputs it to the display 11 by superimposing it on the video signal.

The dictionary database 13 stores, for example, an English-Japanese dictionary, and supplies an explanation (Japanese translation) of a word (English word) to the control unit 2 in response to a request from the control unit 2.

FIG. 2 shows an example of the operation input unit 1 including a remote controller and the like. The operation input unit 1 includes general buttons such as a play button, a play stop button, a pause button, a rewind button, and a fast forward button, as well as a translation mode during playback or a release of the translation mode. Translation mode button 2 to press
1, a cursor button 22 to be pressed when selecting a word of a subtitle character string, and an enter button 23 to be pressed when the selection by operating the cursor button 22 is decided and the explanation of the decided word is displayed Has been.

It should be noted that the translation mode button 21, the cursor button 22, and the enter button 23 may be provided with buttons having the same functions in the main body of the DVD player.

Next, the translation process of the DVD player will be described with reference to the flowchart of FIG. This translation processing is always repeatedly executed while the AV content recorded on the DVD 1 is reproduced.

In step S1, the control unit 2 controls the translation mode button 2 based on the operation information from the operation input unit 1.
It is determined whether or not 1 is pressed, and the translation mode button 21
Wait until is determined to have been pressed. If it is determined that the translation mode button 21 is pressed, the translation mode is set, and the process proceeds to step S2. In step S2, the control unit 2 controls the related units to temporarily stop the reproduction of video, audio, and subtitles. In addition, the control unit 2
Reception of an operation for selecting a word of a subtitle character string from a user is started.

FIG. 4A shows a display example of the display 11 when the acceptance of an operation for selecting a word in a character string of a subtitle from the user is started. Display 1
1 is a subtitle character string "You take the red pill. You stay in wonderlan" at a predetermined position of the AV content video.
"d." is superimposed and displayed, and the first word "You" in the character string is highlighted to indicate that it is in the selected state. Possible methods include changing the display color, changing the font and size of characters, displaying underlines, and blanking.

At this time, when the user presses the cursor button 22, the selected (highlighted) word is switched.

In step S3, the control section 2 determines whether or not the enter button 23 has been pressed based on the operation information from the operation input section 1. If it is determined that the decision button 23 has not been pressed, the process returns to step S2, and the word selection is continuously accepted. Step S
If it is determined in 3 that the decision button 23 has been pressed, the process proceeds to step S4.

FIG. 4B shows a display example of the display 11 in a state where the word "pill" is selected from the subtitle character string. When the determination button 23 is pressed in this state, the word "pill" is determined.

In step S4, the control unit 2 refers to the dictionary database 13 to obtain the explanation sentence corresponding to the determined word and supplies it to the OSD unit 10. O
Under the control of the control unit 2, the SD unit 10 superimposes the supplied description of the word on the video and outputs the superimposed text to the display 11.

FIG. 4C shows a display example of the display 11 in the state where the explanation sentence (Japanese translation) of the word "pill" is displayed.

In step S5, the control section 2 determines the translation mode button 2 based on the operation information from the operation input section 1.
It is determined whether 1 has been pressed. Translation mode button 2
When it is determined that 1 has not been pressed, the current state of the translation mode is maintained, the process returns to step S2, and the subsequent processes are repeated. If it is determined in step S5 that the translation mode button 21 has been pressed, the process proceeds to step S6. In step S6, the control unit 2 cancels the translation mode. That is, the control unit 2 controls the related units to erase the description of the word in which the video is superimposed and displayed, and restarts the reproduction of the video, the sound, and the subtitle. The process returns to step S1. This is the end of the description of the translation process of the DVD player.
