Hereinafter, with reference to the accompanying drawings will be described an embodiment according to the present invention.

FIG. 2 is a block diagram showing an internal configuration of a caption caption automatic cumulative display function television receiver according to an embodiment of the present invention. Components having substantially the same functions as those shown in FIG. The detailed description thereof is omitted.

In FIG. 2, reference numeral 24 denotes a remote control device having a function key for selecting a caption caption display function and a setting key for designating and setting a cumulative display amount of caption caption subtitles. A receiver for receiving an infrared signal and converting and outputting an electrical code signal, and 26 is a microprocessor as a controller for controlling an operation of the entire apparatus including a caption caption accumulation display function based on a code signal applied from the receiver 25. .

Next, the operation of the device having the above configuration will be described.

When the TV receiver is turned on, the caption ID detector 27 searches the composite video signal output from the image detector 9 to detect whether caption ID information is received. In this case, the microprocessor 26 outputs a detection signal of a predetermined level and outputs caption ID information detected by the caption IC 29.

On the other hand, when the user selects the caption function execution key (not shown) provided in the remote control device 24 while the caption broadcast is being received, the microprocessor 26 controls the caption IC 29 by the predetermined control. By outputting a command, the caption IC 29 is controlled to decode the received caption ID information.

When a control command is applied from the microprocessor 26, the caption IC 29 decodes caption ID information applied from the caption ID detector 27 and stores data stored in the caption image storage 28. On the basis of this, the child image corresponding to the decoded caption code data is read and the read image data is output to the caption OSD generating unit 30.

When the caption OSD generating unit 30 is applied with the image data by the above process, the caption OSD generating unit 30 outputs the color tone signals R, G, B and the blanking signal C ′ corresponding to the applied image data to the mixer 32. The mixer 32 mixes the caption signal output from the caption OSD generating unit 30 and the image signal output from the image processing unit 10 and outputs the mixed signal to the CRT driving unit 12 to display the CRT screen. The caption subtitle is output on the screen.

On the other hand, when the user selects the caption caption display function key (not shown) provided in the remote control device 24 while the caption broadcasting reception function is being executed by the above process, the microprocessor 26 The OSD generator 34 is driven to control the output of the OSD guide caption signal for setting the caption accumulation amount. As a result, the video signal of the guide caption output from the OSD generator 34 is passed through the mixer 32. By being applied to the CRT driving unit 12, as shown in FIG. 3, a guide caption for caption accumulation amount setting is output on the CRT screen.

When the user operates the numeric keys of the remote control device 24 to designate and set the accumulated display amount of the caption subtitle according to the guide screen output on the screen, the microprocessor 26 controls the accumulated display amount information input by the user. The caption IC 29 is transmitted to the caption IC 29 together with the signal. The caption IC 29 stores the accumulated display amount information applied from the microprocessor 26 in the accumulation information storage unit 33.

Subsequently, the caption IC 29 stores the decoded caption ID code information corresponding to the amount set by the user in the caption subtitle information storage unit 31 based on the data stored in the cumulative information storage unit 33. By driving the caption OSD generation unit 30 based on the caption ID code information, the caption image including the accumulated caption is output.

The color tone (R, G, B) and the blanking signal (C ′) of the caption subtitle output by the above process is mixed with the image signal in the mixer 32 is output to the CRT driver 12, as a result On the CRT screen, caption captions received over several frames are output as shown in FIG.

That is, according to the above embodiment, when the user designates and sets the caption caption amount, the caption caption amount of the caption is accumulated and displayed on the screen so as to provide time for the user to sufficiently check the content of the caption. It is possible to realize a television receiver with a caption caption display function according to a user specification.

In addition, this invention is not limited to the said Example, It can implement in a various deformation | transformation in the range which does not deviate from the technical summary of this invention.

As described above, according to the present invention, the caption caption information is accumulated and displayed on the screen by the user-specified amount, so that the user can have enough time to check the contents of the caption, thereby providing the language learning effect provided by the caption function. It becomes possible to raise more.
