The digital video disc drive microcomputer 200 has an internal timer that is operated to output at a set time when data is input.

3 is a flowchart illustrating an operation relationship of an information processing apparatus by digital processing in the digital video disk drive apparatus according to the present invention.

When the digital video disk drive apparatus is turned on in step S301, the viewer views the broadcast signal received by the tuner (S302), and in step S302, the viewer enters the key input unit (not shown). (S303), and if the input of the voice multiplex data is completed in step S303, checking whether text data is input (S304) and step S304. If the input of the text data is not confirmed in step S303, and if the input of the text data is confirmed, storing the input text data in the message memory unit 600 (S305) and the message in step S305 At step S306, the internal timer of the digital video disc drive microcomputer 200 is operated from the time point at which the character data is stored in the memory unit 600, and the tie at step S306. In operation S307 and step S307, the message receiving unit 720 receives the text data stored in the message memory unit 600 by the control signal of the digital video disk drive microcomputer 200 when the operation time is reached. Decoding the received character data (S308), and when the decoding of the character data is completed in step S308, reading the standard code data from the standard code support unit 780 and encoding the decoded character (S309), and Converting the coded character data into voice code data (S309), combining voice code data coded in step S310 (S311), and voice code data combined in step S311; Generating a speech signal by continuously synthesizing the speech signal (S312), amplifying and outputting the synthesized speech signal in step S312 (S313), and outputting the speech signal in step S313. Checking whether to turn off the message output (S314), and if the message output off is not confirmed in step S314, returning to step S306; and if the message output off is confirmed, turning off the output message. (S315) is shown. Referring to the operational relationship according to an embodiment of the present invention.

When the digital video disc drive device is turned on by supplying power (S301), the broadcast signal transmitted from the broadcasting station is received through the tuner 100.

At this time, the digital video disc drive microcomputer 200 processes the contrast, bright, R, G, and B signals, which are contrast ratios of the screen with respect to the broadcast signal received through the tuner 100, to the video processor 300 by processing the signals. Enter it.

Accordingly, the video processor 300 processes the broadcast signal processed by the digital video disk drive microcomputer 200 to output the R, G, and B signals to display an image signal on the screen of the cathode ray tube 400 so that the viewer can watch it. Make sure

Also, The digital video disc drive microcomputer 200 inputs a control signal for processing a voice signal from the broadcast signal to the sound processor 500, processes the voice signal by the sound processor 500, and processes the voice signal through the sound amplifier 520. The signal is amplified to a predetermined level and output to the speakers 522 and 524 so that the viewer can listen to the audio information while watching the image displayed on the screen of the cathode ray tube 400 (S302).

At this time, when the viewer sets and inputs audio multi-data by time through a key input unit (not shown) while viewing the digital video disc drive (S303), the digital video disc drive microcomputer 200 inputs the viewer by the set program. If the data input is not confirmed, the digital video disc drive microcomputer 200 allows the viewer to continuously input the audio multiple data (S303), and if the input of the audio multiple data is confirmed, the input text data is input to the message memory unit 600. Stored in step S305).

At this time, the internal timer of the digital video disk drive microcomputer 200 is operated for a time set by the viewer from the time point at which the text data of the message memory unit 600 is stored (S306).

When the internal timer of the digital video disk drive micom 200 is activated and the set time has elapsed, the digital video disk drive micom 200 reads and outputs the voice multiplex data stored in the message memory unit 600. The message receiving unit 720 receives the voice multiplex data stored in the message memory unit 600 (S307).

The voice multiple data received by the message receiver 720 is decoded via the decoder 740 to decode the received voice multiple data and input the decoded voice multiple data to the encoder 760 (S308).

At this time, the encoding unit 760 codes the speech multiplex data decoded by the standard code data supported by the standard code support unit 780 (S309).

Here, the encoding unit 760 codes only the data that matches the standard code data supported by the standard code support unit 780 in encoding the decoded voice multiplexed data, and does not code the data that does not match.

That is, the standard code support unit 780 needs to set standard code data for each character in advance.

Therefore, the speech multiplex data coded by the encoding unit 760 is converted into code data for outputting speech by the sound code conversion unit 820 of the speech conversion apparatus 800 (S310).

The voice code data converted by the sound code conversion unit 820 is combined through the sound combination unit 840 and input to the synthesis unit 860 in accordance with the spacing, spelling, etc. of the voice code data (S311).

Therefore, the synthesizer 860 continuously synthesizes the voice data in which the spacing, spelling, etc. are matched by the sound combination unit 840, and outputs a voice signal matching the text data input by the viewer to the sound amplifier 520. (S312).

At this time, when the audio signal is synthesized and input to the sound amplifier 520, the digital video disc drive microcomputer 200 outputs a control signal for temporarily stopping the original broadcast signal processed by the sound processor 500. 500).

Therefore, the audio signal continuously synthesized by the synthesis unit 860 is amplified to a certain level via the sound amplifier 520 and output to the speakers 522 and 524 to express the daily routine to be performed at the time set for the viewer. Transfer to (S313).

When the audio signal is output to the speakers 522 and 524, the digital video disc drive microcomputer 200 confirms whether to turn off the message output (S314).

If it is confirmed that the message output off is not confirmed, the digital video disc drive microcomputer 200 returns to step S306 to repeat the above processes, and if the message output off is confirmed, the message is turned off (S315). ), Allowing viewers to watch the audio multicast program they want to watch that day, or to continue watching digital video disc drives.

4 shows an example of the configuration of the digital video disc drive device 62. As shown in FIG.

First, the optical pickup 62b reads out data recorded from the digital video disc 62a. In order to have error correction capability, the bitstream is added with error correction information in some manner, and further modulated and recorded in order to be converted into a data string suitable for a recording medium.

Therefore, the data read out from the digital video disc 62a is first demodulated by the demodulation circuit 62c, and furthermore, error correction is performed by the error correction circuit 62d, resulting in a desired bitstream. This bitstream becomes output data from the digital video disc drive 62.

The bitstream reception tuner 63 receives the bitstream transmitted by radio waves and transmits the received bitstream to the digital network 64.

As described above, in the present invention, when the viewer inputs and stores data about a day's audio multicast program by time zone, when the time set while viewing the digital video disc drive elapses, the text data is automatically stored in the message memory unit. Reads the code data for each character and converts it into voice data, and outputs the information about the list of voice multicast programs input by the viewer through the speaker so that the viewer can read the voice data output to the speaker while viewing the digital video disc drive. By listening to the voice multicast program list of the day, the voice multicast program to be watched is forgotten.

From the above, the information processing apparatus by digital processing in the digital video disk drive apparatus according to an embodiment of the present invention has been described. However, the present invention is not limited thereto, and those skilled in the art can variously apply and modify them. .
