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.
MPEG decoder consists of existing MPEG-2 decoder and single chip combined the digital
signal processing part which is the core technology of DVD player with the Servo
controller.
1. DVD Servo And MPEG-2/MPEG-4/DIVX Decoder : ES6698
7
The ES6698 Vibratto™II processor is a highly integrated single-chip DVD solution
that integrates read channel, ECC, Servo DSP, MCU, and MPEG-2/MPEG-4/DivX
decoder that has a state-of-the-art 480p/576p progressive-scan video feature to
provide brilliant and sharp, flicker-free video output to the display, and with built-in
gamma correction and S/PDIF input and output support. The ES6698 performs
audio/video stream data processing, TV encoding, Macrovision™ copy protection,
DVD system navigation, system control, and housekeeping functions.
The Vibratto-II DVD processor is built on the ESS proprietary dual CPU Programmable
Multimedia Processor(PMP) core consisting of 32-bit RISC and 64-bit DSP processors
and offers the best DVD feature set. The processing units enable simultaneous
parallel execution of system commands and data processing to perform specialized
enconding and decoding tasks.
The RISC processor performs bit stream parsing, control audio data output, transfer
video and audio data to the vector engine and service system control and
housekeeping functions. The vector engine performs audio and video micro-code
processing required by A/V standards, such as Dolby Digital®, MPEG and JPEG
imaging. These processing tasks include video motion compensation and estimation,
loop filtering, Discrete Cosine Transforms(DCT), inverse DCT, quantization, and
inverse quantization.
The Vibratto-II DVD processor supports all popular pick-up units, industry standard
I²S audio data input and output, EPROM and DRAM access. It also supports both
letterbox and pan-and-scan displays, sub-picture overlay, and On-Screen
Display(OSD).
The Vibratto-II’s Unified Memory Architecture enables the lowest possible system
memory cost by consolidating multiple memory subsystems into a single unit.
In addition, the Vibratto-II DVD solution offers support for Karaoke CD+G, DVD-
Aduio, HDCD, CD-DA, Mp3, and WMA.
The ES6698 Vibratto-II DVD processor with DTS support is offered with the
ES6698D, which has the same pinout as the standard ES6698. DTS support is
provided via software and only works with the ES6698 and ES6698D DVD processors
are available in 2 208-pin Plastic Quad Flat Pack(PQFP) device package.
