ES4408
DVD Processor
Product Brief
DESCRIPTION
The ES4408 Processor is a single-chip solution for a Digital
Versatile Disc (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 ES4408 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 ES4408 is the most cost effective
solution in its class with an integration level and quality that set
new benchmarks.
The ES4408 processor is capable of decoding Dolby™ Digital
(AC-3) up to 5.1 channels or MPEG audio up to 7.1 channels
simultaneously with MPEG-1 or MPEG-2 video. For embedded
applications, the ES4408’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 useful for video standards
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 ES4408 are video letterbox display, DVD Sub-Picture
overlay, and On-Screen Display.
The ES4408 provides a glueless 8/16-bit parallel interface to
many 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
2
S interface
supports popular audio DACs and ADCs. The ES4408 also
features a direct S/PDIF output. Figure 1 shows a block diagram
of a typical standalone system using the ES4408 with the
glueless SDRAM interface.
The DVD system stream from a DVD disc is passed to the ™
ES4408 through the 8-bit/16-bit parallel host interface. The ™
ES4408 parses the system layer and demultiplexes the audio
and video streams. Audio is decoded and passed through the I
2
S
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.
