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

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
to control various peripheral devices. A standard I

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
and video streams. Audio is decoded and passed through the I

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.
