Data stored in the caption image storage unit 30c and the caption image storage unit 30c that store image data corresponding to the corresponding caption code with respect to the captured caption code. Based on the control of the microprocessor 26, a caption IC 30d for reading out and outputting a caption image for a user-specified search word and a caption video signal corresponding to image data applied from the caption IC 30d is output. Caption OSD generation unit 30e is composed.

On the other hand, reference numeral 33 is an OSD generator for outputting an image signal of the OSD guide caption for inputting a search word under the control of the microprocessor 26, 32 is the OSD generator 33 and the image processor 10 And a mixer (MIXER) for mixing the video signals output from the caption OSD generating unit 30e and outputting them to the CRT driving unit 12.

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

If the user selects the caption function by operating the remote control device 24 while watching TV, the microprocessor 26 outputs a predetermined control signal to the caption IC 30d in the caption decoder 30. 30d stores the caption code extracted and applied by the caption ID detection unit 30a in the caption subtitle information storage unit 30b and stores image data corresponding to the extracted caption code in the caption image storage unit 30c. By driving the caption OSD generating unit 30e based on the image data read out from the image data, the caption subtitle corresponding to the video screen output on the CRT is output.

On the other hand, in the state that the caption function is being executed according to the above process, if the user selects a search word confirmation key provided in the remote control device 24 to check the utilization example for the word that has already passed, the microprocessor ( 26 controls the OSD generator 33 to output an OSD guide subtitle for inputting a search word on the screen as illustrated in FIG. 3.

In response to this, when a user inputs a search word through a selection key (not shown) while moving a position of the cursor by operating a channel up / down key provided in the remote control device and presses the search word confirmation key when the input is completed, The microprocessor 26 stores the search word information input by the user in the search word information storage 34 and outputs a predetermined control command to the caption IC 30d.

Meanwhile, when a predetermined control signal is applied from the microprocessor 26, the caption IC 30d indexes a user-specified search word from the caption subtitle information storage unit 30b to read caption information of a sentence including the search word. Then, the caption IC 30d reads the image data corresponding to the caption information including the search word based on the data stored in the caption image storage unit 30c, and accordingly the caption OSD generating unit 30e is read. By driving, a caption video signal corresponding to the read image data is output.

As a result, the caption video signal is transmitted to the CRT driver 12 through the mixer 32, so that the sentence including the user-specified search word is reproduced and output on the CRT screen as illustrated in FIG.

That is, according to the embodiment, the user can extract the caption information through the function setting, and play the sentence content including the word by specifying the search word to double the effect of language learning through the caption function. It is possible to realize a television receiver equipped with a caption information index function based on a search word that can be used.
