The character switching device 700 includes a character ID retrieving unit 710 for retrieving a unique ID for a character in a video signal processed by the image processor 300, a decoder 712 for decoding the retrieved character ID, A data slice unit 714 for receiving data from the decoder unit 712 and checking a frame of the decoded character data and a data slice unit 714 for searching for a data clock from the character ID decoded by the control signal of the microcomputer 200, A read unit 720 for reading the data clock of the searched character ID, a read unit 720 for reading the data clock of the searched character ID, And an output unit 722 for outputting the read character data and inputting the read character data to the image processor 300.

FIG. 3 is a flowchart illustrating an operation procedure of a television receiver including a character automatic switching device according to the present invention. In step S301, A step S303 of determining whether the character switching function is on during TV viewing, a step S311 of outputting the received voice as it is when the character switching function is off due to no input of the determined result, (S304) of searching for a character ID if there is a key input and a character switching function is on, decoding the retrieved character ID and checking a character data frame (S305), retrieving a character data clock (S306), a step (S307) of reading out a character data clock, a step (S308) of judging whether the read character data is faster than a set voice speed, and a step (S309) of outputting character data in accordance with a correct voice if the read character data is earlier than the set voice speed, a step S310 of judging whether the character switching function is off, The process returns to step S304 if the character switching function is on because no key input is made, and if the character switching function is off, step S311 of outputting the received voice as it is.

When the viewer operates the key input unit 220 to select a broadcasting channel to be watched while the power is supplied (S301), the microcomputer 200 recognizing the selected broadcasting channel responds thereto And applies the selected channel selection voltage to the tuner 100. [ Accordingly, the tuner 100 tunes a broadcast signal of a broadcast channel selected by the channel selection voltage generated by the microcomputer 200 to a broadcast signal received from a free space through an antenna ANT, 500, respectively. The image processor 300 processes the video signal in the broadcast signal input from the tuner 100 according to the control signal of the microcomputer 200 and inputs the processed video signal to the video amplifier 320. That is, the image amplifying unit 320 amplifies the image signal to a level that can be displayed on the screen of the CRT 400, and supplies the amplified image signal to the CRT 400. As a result, The viewer views the image (S302).

When watching the TV, the microcomputer 200 determines whether the character switching function is on (S303), and there is no key input for switching a fast voice to a character in the key input unit 220 so that the character switching function is turned off The audio signal received by the tuner 100 and processed by the audio processor 500 is amplified to a predetermined level through the audio amplifying unit 520 and outputted as it is to the speakers 600 and 620 in S311, So that the user can listen to it. However, if the microcomputer 200 determines that the character switching function is on (S303) and the key input unit 220 has a separate key input for switching and displaying the quick voice in the character mode, the microcomputer 200 Outputs a control signal to the character ID retrieving unit 710 of the character switching device 700 so that the character ID retrieving unit 710 retrieves a unique number (ID (S304), and decodes the retrieved character ID through the decoder unit 712. [ At this time, the data slice unit 714 which exchanges data with the decoder unit 712 checks the frame of the decoded character data (S305) and inputs it to the decoder unit 712. That is, the character data decoded by the decoder unit 712 is input to the retrieving unit 716. The retrieving unit 716 retrieves the character data from the support unit 718 by using the control signal of the microcomputer 200 (S306), and reads the clock of the character data through the reading unit 720 (S307), and inputs the decoded character data to the image processor 300 via the output unit 722. [ Accordingly, the image processor 300 determines whether the character data input from the output unit 722 is faster than the set voice rate in accordance with the control signal of the microcomputer 200 (S308). The microcomputer 200 outputs a control signal to the character ID retrieving unit 710 of the character switching apparatus 700 so that the character ID retrieving unit 710 retrieves The processor 300 searches for the unique number (ID) of the character data in the video signal processed by the processor 300 (S304), and continues the process in the order described above. If the character data input from the output unit 722 is faster than the set voice rate, the voice signal is processed as character data and output (S309), and the CRT 400 is output through the image amplification unit 320. [ A character is displayed on the screen so that the viewer can read the displayed character while listening to the voice. When the character data according to the audio output is displayed on the CRT 400, the microcomputer 200 determines whether the character switching function is off (S310). If there is no key input in the key input unit 220, The microcomputer 200 outputs a control signal to the character ID retrieving unit 710 of the character switching device 700 so that the character ID retrieving unit 710 can read the character data from the video signal processed by the image processor 300 (ID) is searched for (S304), and the process is continued from the process in the above-mentioned order. If the result of the determination in step S310 is that the key switching unit 220 is turned off and the character switching function is turned off, the voice signal received by the tuner 100 and processed by the voice processor 500 is transmitted to the voice amplifying unit 520 Amplifies it to a predetermined level through the speaker 600 and outputs it to the speakers 600 and 620 in S311 so that the viewer can listen to the fast voice.

As described above, according to the present invention, when a voice of a performer is output quickly during a TV viewing, when a viewer turns on a character switching function, a voice which is difficult to listen is automatically searched and a voice outputted at present is output to a CRT screen So that the viewer can accurately understand the fact that the viewer can not easily listen to the voice.

Although the present invention has been described with reference to an apparatus for automatic character switching by speech recognition of speed of sound and a method thereof as described in the claims, the present invention is not limited thereto, and various applications and modifications can be made by those skilled in the art something to do.
