ES4318

DVD Processor

Product Brief

DESCRIPTION

The ES4318 Digital Video Disc (DVD) processor is a single-chip

solution for a DVD player that integrates MPEG video decoding,

DVD system navigation, Content Scrambling System (CSS), and

Dolby™ Digital (AC-3) and MPEG audio decoding. The fully

programmable ES4318 is based on a proprietary ESS

architecture. It offers the best feature set in comparison to any

currently existing DVD chip, and a glueless interface to various

peripheral components. The ES4318 is the most cost effective

solution in its class with an integration level and quality that set

new benchmarks.

The ES4318 processor is capable of decoding Dolby™ Digital

(AC-3) or DTS digital surround, simultaneously with MPEG-1 or

MPEG-2 video. For embedded applications, the ES4318’s

internal RISC processor can be used in place of a microcontroller

to provide all system control, DVD system navigation, CSS

decryption, and many other features. On-chip, multi-tap filters

provide arbitrary scaling with state of the art SmartScale™

technology

conversion.

SmartStream™ technology from ESS provides video error

concealment and video post-processing, leading to the highest

playability and video quality. Other features included in the

ES4318 are video letterbox display, DVD Sub-Picture overlay,

and On-Screen Display.

The ES4318 provides a glueless 8/16-bit parallel interface to

most DVD servo/loaders. It connects directly with 8/16-bit ROM

and 16-bit SDRAM/EDO. An 8-bit YUV video interface supports

many TV encoders. General purpose auxiliary pins are provided

supports popular audio DACs and ADCs. The ES4318 also

features a direct S/PDIF output. A block diagram of a typical

stand-alone system using the ES4318 with the glueless SDRAM

interface appears below.

The DVD system stream from a DVD disc is passed to the

ES4318 through the 8-bit/16-bit parallel host interface. The

ES4318 parses the system layer and demultiplexes the audio

audio serial bus to an external audio DAC and then to the

speakers. Video is decoded and output as YUV pixels to an

NTSC or PAL video encoder. System control and housekeeping

functions (keypad and remote control) are also provided on-chip.
