Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are denoted by the same reference numerals as much as possible even if displayed on the other drawings.

2 is a block diagram of a multi-channel multimedia device according to the present invention.

In FIG. 2, the present invention includes a system controller 10, a digital signal processor 20, a video processor 30, an audio processor 40, a pickup / servo mechanism unit 50, and a servo controller 60. The DVD player includes a multimedia controller 80, a key input unit 90, a DVD-RW unit 100, a MIDI / MP3 sound source unit 110, a video PIP controller 120, and an audio controller 130.

The pickup / servo mechanism portion 50 is composed of a spindle motor (not shown) for driving the DVD 70 and an adjustment mechanism (not shown) including a pickup for accurately reading information from the high density DVD 70. The signal processor 20 inputs the data picked up and read by the pickup / servo mechanism unit 50, processes the RF signal by the RF signal processor 21, and demodulates the demodulator 22 at an 8/16 ratio. The error correction unit 23 corrects the error.

In this case, the DVD 70 is processed by the multimedia controller 80, the key input unit 90, the DVD-RW unit 100, the MIDI / MP3 sound source unit 110, the video PIP controller 120, and the audio controller 130. This is a multimedia multi-function medium with various control programs for controlling and selecting multimedia information. The programs stored in the multimedia multi-function medium for outputting multimedia information by section include games, web browser programs, image data, MIDI / MP3 data, The lyrics erase data as the lyrics and performance progress and data related to the song selection function are recorded.

The variable rate controller 24 controls the variable rate of error corrected data in the error correction unit 23 and transmits the variable rate to the descrambler 25, and the descrambler 25 is transmitted from the variable rate controller 24. Data is descrambled and transmitted to the data separator 26, and the data separator 26 separates the descrambled data from the descrambler 25 into video and audio data.

The system control unit 10 incorporating a OneChip microprocessor includes a digital signal processing unit 20 so that the digital signal processing unit 20 separates the video and audio data in real time and sends them to the video processing unit 30 and the audio processing unit 40, respectively. 20). In addition, the system controller 10 performs navigation control to interactively process the image software of the DVD 70. The video processor 30 that inputs the video data separated by the data separator 26 of the digital signal processor 20 includes a video decoder 31, a sub picture unit 32, an OSD display unit 33, and a video encoder 34. ) And the VDAC 35 to process the video data and output the TV signal through the output terminal OUT1. In addition, the audio processing unit 30 that inputs the audio data separated by the data separation unit 26 of the digital signal processing unit 20 includes a Dolby Surround unit 41, a linear PCM unit 42, an audio decoder 43, and an ADAC. Audio data is processed using 44 to output an audio signal through the output terminal OUT2.

On the other hand, the multimedia controller 80 controls the digital signal processor 20 to process data of the DVD 70 detected by the pickup / servo mechanism unit 50, and provides over-the-air / cable TV information and image information of an image camera. Internet information connected through the USB port and voice information through the microphone are input and controlled through the input terminals IN1, IN2, IN3, and IN4, respectively, and transmitted to the RF signal processor 21 of the digital signal processor 20. . The key input unit 90 has an interrupt key and a general function key to select multimedia functions to satisfy various needs of the user. When the user selects the Internet function, the video input, video chat, Home shopping, e-commerce, e-banking, auctions, real estate transactions, e-mail and various computer games can be used in real time according to the user's taste. Through the operation of the key input unit 90 according to the user's preference, airwave / cable TV information inputted to the input terminals IN1, IN2, IN3, and IN4, image information of the image camera, and Internet information connected to the USB port. When the voice information through the microphone is controlled and processed by the multimedia controller 80, the user can select and watch channels such as education, documentary, medicine, various sports, e-commerce, movies, music, and news, and select music learning. Songs, pop songs, healthy songs, nursery rhymes. You can search for songs, hymns, operas, and classical music that you can listen to along with the wallpaper or sing along. In addition, when a user selects to watch a movie, a number of movies recorded on the DVD 70 can be viewed in a high quality, high resolution, and 5.1-channel method.

At this time, when the user selects the multimedia information and wants to record the necessary contents during use, the DVD-RW unit 100 can be used, and when the user wants to search the recorded contents again, the pickup / servo mechanism unit 50 can be checked. have. The DVD-RW unit 100 is a peripheral device which is very useful for permanently storing data for backup or important educational materials on the DVD 70.

The multimedia controller 80 is output from the descrambler 25 to mix the pre-separation signal and the post-separation signal that do not pass through the data separation unit 26 to interface with the MIDI / MP3 sound source unit 110. The MIDI / MP3 sound source unit 110 converts the data interfaced from the multimedia control unit 80 and the voice data input through the input terminal into a synthesizer to have reverberation and chorus effect sounds, and thereby the audio processing unit 40. Outputs to output terminal (OUT2) via).

The video PIP controller 120 controls the video information of the multimedia information to be displayed for each section on the output screen according to the control signal of the multimedia controller 80, and the audio controller 130 controls the multimedia according to the control signal of the multimedia controller 80. Control audio information of the information to be provided to the user.
