  • Page 4 CIRCUIT OPERATIONAL DESCRIPTION DVD Module . Summary DVD One Board consists of: Loader part that reads and transmits audio and video data saved at Optic Discs (DVD, CD-DA, VCD, CD-R) to MPEG Decoder part; MPEG Decoder part, which, by decoding and encoding data received from the Loader, produces analog signals; and u-Com that controls the overall system including the loader and MPEG decoder.
  • Page 5 CIRCUIT OPERATIONAL DESCRIPTION CIRCUIT OPERATIONAL DESCRIPTION 3. Loader Part The loader which read the data of audio/video from optic disc and transfer them to MPEG decoder can be divided into Deck total DVD assay(in a short term, Mecha) and Servo. Mecha mounts with the optical pick-up which allows reading the signal of a disc using laser beam and makes it operates and consists of the deck mechanism which allows loading a disc and reading the data.
  • Page 6 CIRCUIT OPERATIONAL DESCRIPTION CIRCUIT OPERATIONAL DESCRIPTION ) Motor Drive IC: AT5888S The AT5868S is a 5-channel BTL driver IC for driving the motors and actuators in products such as CD-ROM/DVD-ROM/DVD-Player drives. Two of the channels use current feedback to minimize the current phase shift caused by the influence of load inductance. Driver IC gener- ates the focus signal and the tracking signal for pick-up actuator, the sled signal for feed, spindle signal and the load signal for opening and closing of the tray.
  • Page 7 CIRCUIT OPERATIONAL DESCRIPTION MPEG Decoder The signal read from DVD disc is output into the RF signal and Servo related signal through the RF IC and they are input into the MPEG decoder and processed the MPEG decoding and divided into video/audio signal. The video signal is output into the analog audio signal through the built-in encoder block and also the audio signal into the audio DAC through the audio decoder block.

  • Page 13 CIRCUIT OPERATIONAL DESCRIPTION 3) EEPROM : AT24C6A This stores the information related to setup of DVD menus. This can read and write the op- tional information such as OSD, voice, language option after function for subtitle etc, the aspect or method of TV display, video option like display function and audio, screen saver, parental function through the I2C transmission method.
  • Page 14 CIRCUIT OPERATIONAL DESCRIPTION 4) SDROM : M2L66A-7T (for DVD-DX500 and DVD-DX50) This sends and receives data with MPEG decoder and performs the video signal processing. Every video signal output from DVD player is once stored in SDRAM and then encoded in MPEG decoder and finally output into the analog signal.
  • Page 15 CIRCUIT OPERATIONAL DESCRIPTION SDROM : PT48046TG-70 (for DVD-DX50) This sends and receives data with MPEG decoder and performs the video signal processing. Every video signal output from DVD player is once stored in SDRAM and then encoded in MPEG decoder and finally output into the analog signal. SDRAM applied to DVD module has the capacity of 32MBit(048576 x 6bit x 2Bank), sends and receives data with MPEG decoder by 6 bit.
