Abstract

A closed caption decoder with a pause function suitable for learning a language comprising: a closed caption decode circuit for decoding closed caption signals included in video signals outputted from a video cassette recorder and for outputting a detection signal when a predetermined control code is decoded; a timer which measures an elapse of time from a time when the predetermined control code is decoded; and a pause control circuit for instructing the caption decode means to perform a pause operation of caption decode and the video cassette recorder to perform a pause of video reproduction when the detection signal is outputted form the closed caption decode circuit and for outputting a pause termination signal of caption decode to the closed caption decoder and a pause termination signal of video reproduction to the video cassette recorder when the timer measures a predetermined period of time.

Claims

1. A closed caption decoder with a pause function suitable for learning a language, comprising:

a closed caption decode means for decoding closed caption signals included in video signals outputted from a video cassette recorder and for outputting a detection signal when a predetermined control code is decoded;

an input processing means for performing processing of input of an instruction indicating a termination of a pause operation from a user; and

a pause control means for instructing the caption decode means to perform a pause operation of caption decode and the video cassette recorder to perform a pause of video reproduction when the detection signal is outputted from the closed caption decode means, and for outputting a pause termination signal of caption decode to the closed caption decoder and a pause termination signal of video reproduction to the video cassette recorder when an instruction indicating a termination of a pause operation is inputted from a user by the input processing means.

4. A closed caption decoder according to claim 1, further including a video cassette recorder control circuit, connected to the pause control means, for controlling the video cassette recorder when the pause termination signal of video reproduction is inputted from the pause control means in such a way that the pause operation of video reproduction is terminated, thereafter the video tape is rewound as much as a second predetermined period of time and thereafter the video tape is reproduced.

7. A closed caption decoder according to claim 1, wherein the predetermined control code is a code indicating an erasure of closed caption displayed on a screen.

10. A closed caption decoder according to claim 4, wherein the predetermined control code is a code indicating an erasure of closed caption displayed on a screen.

2. A closed caption decoder with a pause function suitable for learning a language, comprising:

a closed caption decode means for decoding closed caption signals included in video signals outputted from a video cassette recorder and for outputting a detection signal when a predetermined control code is decoded;

a timer which measures an elapse of time from a time when the predetermined control code is decoded; and

a pause control means for instructing the caption decode means to perform a pause operation of caption decode and the video cassette recorder to perform a pause of video reproduction when the detection signal is outputted form the closed caption decode means and for outputting a pause termination signal of caption decode to the closed caption decoder and a pause termination signal of video reproduction to the video cassette recorder when the timer measures a first predetermined period of time.

3. A closed caption decoder according to claim 2, further including a timer setting means for setting the first predetermined period of time in the timer.

5. A closed caption decoder according to claim 2, further including a video cassette recorder control circuit, connected to the pause control means, for controlling the video cassette recorder when the pause termination signal of video reproduction is inputted from the pause control means in such a way that the pause operation of video reproduction is terminated, thereafter the video tape is rewound as much as a second predetermined period of time and thereafter the video tape is reproduced.

6. A closed caption decoder according to claim 3, further including a video cassette recorder control circuit, connected to the pause control means, for controlling the video cassette recorder when the pause termination signal of video reproduction is inputted from the pause control means in such a way that the pause operation of video reproduction is terminated, thereafter the video tape is rewound as much as a second predetermined period of time and thereafter the video tape is reproduced.

8. A closed caption decoder according to claim 2, wherein the predetermined control code is a code indicating an erasure of closed caption displayed on a screen.

9. A closed caption decoder according to claim 3, wherein the predetermined control code is a code indicating an erasure of closed caption displayed on a screen.

11. A closed caption decoder according to claim 5, wherein the predetermined control code is a code indicating an erasure of closed caption displayed on a screen.

12. A closed caption decoder according to claim 6, wherein the predetermined control code is a code indicating an erasure of closed caption displayed on a screen.
