Description

Combination system having an optical recording / reproducing apparatus and a television, and a control method for displaying caption and subtitle

The present invention relates to an optical recording / reproducing apparatus and a television, and more particularly, to an optical recording / reproducing apparatus and a television composite apparatus.

Two or more different devices connected to one integrated system are called a "combination system" or a "combo-system", which is abbreviated as "combo". As an example of a combo system, a composite device capable of performing a combination of functions of a television and a digital versatile disk player (DVDP) has been developed.

A television is a device for receiving and broadcasting a broadcast signal received from a broadcasting station, and a DVDP is a device for reproducing data recorded on a digital versatile disk (DVD).

Recently, for the hearing impaired, the broadcasting station has been generally used to transmit caption data including caption data in the vertical blanking interval (VBI) of the broadcast signal CVBS. Accordingly, the television provided with a separate caption unit for decoding caption data included in the broadcast signal provides convenience for the hearing impaired and the viewer who needs the caption broadcasting.

On the other hand, the DVDP is a device for reproducing data recorded on a DVD, and reproduces data recorded on the DVD, that is, video data, audio data, subtitle data, and navigation. In addition, in the United States, as caption data is standardized to include separate caption data in video data such as broadcasting and VCR for the hearing impaired, caption data is included in the composite video signal CVBS.

The subtitle part in the general DVDP decodes the subtitle data recorded on the DVD, and does not decode the video data, that is, the caption data contained in the composite video signal CVBS.

However, in the composite apparatus of DVDP / TV, the caption data contained in the composite video signal of the DVD can be decoded by the caption portion in the television. When the caption portion in the television is in operation, when the DVDP is operated to reproduce the data recorded on the DVD, the subtitle portion of the DVDP and the caption portion in the television are simultaneously operated to decode the subtitle data and the caption data, respectively. Accordingly, there is a problem in that the subtitle data and caption data decoded are superimposed on the screen of the television.

SUMMARY OF THE INVENTION An object of the present invention for solving the above problems is an optical recording / reproducing apparatus and a television composite in which caption data and subtitle data are not superimposed on the screen of a television when data recorded on an optical recording medium is reproduced. To provide a device.

Therefore, it is possible to prevent the subtitle data and the caption data from overlapping on the screen.

Hereinafter, with reference to the drawings will be described the present invention in more detail. In this embodiment, a composite apparatus to which DVDP is applied as an optical recording / reproducing apparatus will be described as an example.

Fig. 1 is a detailed block diagram of the composite device of the DVDP 300 and the television 400 according to the present embodiment.

The DVDP 300 may include a DVD deck 31, a DE-MUX 32, a video decoder 33, an audio decoder 34, a subtitle unit 35, an encoder 36, an audio amplifier 37, and It has a DVD microcomputer 38.

The DVD deck 31 reads data recorded on the DVD.

The DE-MUX 32 separates the data read from the DVD deck 31 into video data, audio data, and subtitle data under the control of the DVD microcomputer 38 and outputs the data.

The video decoder 33 restores and outputs the digital video data output from the DE-MUX 32, and the audio decoder 34 restores and outputs the digital audio data output from the DE-MUX 32.

The subtitle unit 35 decodes the subtitle data output from the DE-MUX 32.

The encoder 36 encodes the video data output from the video decoder 33 into a single video signal and converts the video data into a composite video signal CVBS. The composite video signal CVBS includes caption data.

The audio amplifier 37 amplifies the audio data output from the audio decoder 34 and is output to the outside through the speaker 49 provided in the television.

As described, the DVD microcomputer 38 controls the overall operation of the DVDP 300 and transmits and receives a control command to and from the TV microcomputer 48 described later.

The television 400 includes a receiver 41, an input unit 42, a video processor 43, an audio processor 44, a caption unit 45, an OSD generator 46, a mixing unit 47, a TV microcomputer 48 ), A speaker 49, and a CRT 50.

The input unit 42 is an operation panel (not shown) provided with a plurality of buttons on a television main body, a remote control (not shown) that can be adjusted remotely, and the like. The input unit 42 inputs a user's selection command for the operation of the DVDP and the television by the user. For example, a selection command for mode switching is input. Modes include a DVD mode in which a DVDP is operated, a television mode in which a television is operated, and a selection mode for whether or not the subtitle unit 35 and the caption unit 45 are operated. Of course, the DVD mode can be switched between the mode when the DVD is seated on the DVD deck and the television mode when the power is supplied to the composite device.

The audio processor 44 processes the audio signal among the broadcast signals received from the receiver 41, and the signal processed audio signal is output to the outside through the speaker 49.

The video processor 43 performs signal processing on the composite video signal CVBS among the broadcast signals received from the receiver 41 and the composite video signal CVBS output from the encoder 36 in the DVDP 300. The video signal is displayed externally through the CRT screen 50.

The caption section 45 decodes the caption data contained in the composite video signal CVBS, which is a caption broadcast signal, under the control of the TV microcomputer 48.

The OSD generating unit 46 generates caption data and subtitle data decoded from the caption unit 45 and the subtitle unit 35 as an OSD screen.

The mixing unit 47 synthesizes the caption and subtitle generated by the OSD generator 46 and the composite image signal CVBS signal-processed by the video processor 43.

The TV microcomputer 48 controls the operation of the entire television, and transmits and receives a control command with the DVD microcomputer 38.

On the other hand, when the user selects a mode in which the subtitle unit 35 and the caption unit 45 are operated at the same time, the TV microcomputer 48 prevents the subtitle data and the caption data from being superimposed on the CRT screen 50. To control. For example, the TV microcomputer 48 may display the subtitle unit 35 and the caption unit so that the caption data decoded by the caption unit 45 is displayed at a position different from the position where the subtitle data decoded by the subtitle unit 35 is displayed. 45).

Hereinafter, a method of controlling display operations of subtitles and captions in a DVDP / TV composite apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

2 is a flowchart illustrating an embodiment of a method for controlling caption display operation according to the present invention.

When the DVDP 300 is switched to the mode set to be operated (S11), the TV microcomputer 48 receives this command and transmits it to the DVD microcomputer 38. The DVD microcomputer 38 reads the data recorded on the DVD and starts the playback operation as the DVD playback command is transmitted. DVD mode switching can be either manual or automatic. For example, when the mode is manually switched, the user switches the mode through an input unit 42 such as an operation panel and a remote controller. When the mode is automatically switched, the DVD is seated on the DVD deck 31. If it is.

The DVD microcomputer 38 operates the subtitle section 35 (S13). The subtitle unit 35 decodes the subtitle data separated from the DE-MUX 32, and the DVD microcomputer 38 inputs the decoded subtitle data to the OSD generator 46 in the television 400.

At this time, the TV microcomputer 48 checks the operation of the caption unit 45, and if the caption unit 45 is in operation (S15), stops the operation of the caption unit 45 and transmits it from the DVDP 300. The caption data included in the composite video signal is not decoded (S17).

The data read from the DVD deck 31 is output separately from the video, audio, and subtitle data by the DE-MUX 32. Among them, the video data is restored to the original digital video signal by the video decoder 33, and the restored video signal is encoded by the encoder 36 into the composite video signal CVBS. The output composite video signal CVBS is input to the video processor 43 of the television.

Therefore, the subtitle data decoded by the subtitle unit 35 and the composite image signal processed by the video processor 43 are synthesized by the mixing unit 47 and displayed externally through the CRT screen 50.

In addition, the audio data of the DVD is output as a predetermined audio signal by the audio decoder 34 and the audio amplifier 37, and then is signal-processed by the audio processing unit 44 in the television 400, through the speaker 49. It is output to the outside.

2 illustrates an example in which the subtitle unit 35 is automatically operated when the DVD mode is selected, and the caption unit 45 is stopped. However, the user may select the operations of the subtitle part 35 and the caption part 45 through the input part 42 such as an operation panel and a remote controller.

For example, when the DVDP 300 is switched to the mode set to operate, as shown in the flowchart of FIG. 2, the DVD microcomputer 38 operates the subtitle unit 35 to decode the subtitle data to display the CRT screen 50. Displayed together with the video signal.

At this time, when the user switches to the mode in which the caption unit 45 is set to operate, the TV microcomputer 48 transmits a command to stop the operation of the subtitle unit 35 to the DVD microcomputer 38 and thereby the subtitle unit 35. At the same time, the TV microcomputer 48 operates the caption section 45. Accordingly, the caption section 45 in the television 400 decodes caption data included in the composite video signal encoded by the encoder 36 in the DVDP 300 to be displayed together with the video signal on the CRT screen 50. .

In the above case, when the DVDP 300 is operated in the DVDP / TV composite apparatus, the general subtitle part 35 and the caption part 45 are operation control methods.

However, when the user selects a mode in which the subtitle data and the caption data are simultaneously decoded and displayed on the screen 50 when the DVDP 300 is played, the following description will be given.

3 is a flowchart illustrating an operation control method when a mode set to display subtitle data and caption data together on a CRT screen 50 is selected.

When the user selects a mode in which the subtitle part 35 and the caption part 45 of the DVD operate simultaneously through the input part 42 (S21), the TV microcomputer 48 issues a selection command for the mode. 38). The DVD microcomputer 38 operates the subtitle section 35 in response to the selection command. As the subtitle unit 35 operates, the subtitle data input from the DE-MUX 32 is decoded (S23), and the decoded subtitle data is input to the OSD generator 46 in the television 400. .

On the other hand, the TV microcomputer 48 operates the caption unit 45 to decode the caption data contained in the composite video signal CVBS encoded from the encoder 36 in the DVDP 300 (S23). At this time, the TV microcomputer 48 changes the display position of the caption data so that the caption data is not superimposed on the CRT screen 50 and the subtitle data decoded by the subtitle section 38 of the DVDP 300. The caption part 45 is controlled (S25).

Therefore, even when the subtitle data and the caption data are simultaneously displayed on one screen, the positions where the respective data are displayed are different, so that they do not overlap each other.

Accordingly, the processing of the video signal and the audio signal processed in each block is the same as described above, and thus will be omitted.

In this manner, the subtitle data and the caption data overlap on one screen 50 by selectively controlling the operations of the subtitle portion 35 and the caption portion 45 in the television in the DVDP mode. prevent.

Further, even when the subtitle data and the caption data are simultaneously displayed on one screen 50, the subtitle part 35 and the caption part 45 are controlled so that the respective data do not overlap.

According to the present invention, in a mode in which a DVDP is operated in a DVDP / TV composite apparatus, the subtitle part 35 in the DVDP is generally operated, and the operation of the caption part 45 in the TV is stopped, thereby causing the subtitle data and the caption data. The phenomenon of overlapping on one screen 50 can be prevented.

In addition, when the subtitle data and caption data are simultaneously displayed on one screen by the user's selection, the subtitle data 35 and the caption data 45 are controlled to display the subtitle data and the caption data on one screen. It can be displayed in different positions from each other.

Although the preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the specific embodiments described above, and the present invention is not limited to the specific embodiments of the present invention without departing from the spirit of the present invention as claimed in the claims. Anyone skilled in the art can make various modifications, as well as such modifications are within the scope of the claims.
