ES4408
DVD Processor
Product Brief
DESCRIPTION
FEATURES
• Single-Chip DVD video decoder in a 208-pin PQFP package
• Supports MPEG-1 system and MPEG-2 program streams
• Programmable multimedia processor architecture
• Compatible with Audio CD, VideoCD 1.1, 2.0, Interactive
VCD 3.0, and Super VideoCD (SVCD)
• DVD Navigation 1.0
• Built-in Content Scrambling System (CSS)
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.
Video
• Pan & Scan and Letter-Box conversions supported
• Trick modes such as Slow, Fast Forward, Fast Reverse,
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.
Step, and Goto supported
• On-chip subpicture unit (SPU) decoder supports remote
control display functions
• On-chip 4-bit On-Screen Display (OSD) controller with 4-bit
blending supports karaoke lyric and subtitile display
functions.
• 8-bit YUV output
Audio
• Karaoke function
• Dolby™ Digital (AC-3) up to 5.1 channels or 2-channel
downmix audio output for Dolby™ Pro Logic
• MPEG audio up to 7.1 channel
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 I2S 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.
• Linear PCM streams for 48 KHz and up to 96 KHz
• S/PDIF audio output
• Supports 256/384/512 frame sync audio system clocks
Smart Technology
• SmartZoom™ for motion zoom and pan
• SmartScale™ for NTSC to PAL conversion and vice versa
• SmartStream™ for video error concealment
Peripheral
• Bidirectional I2S audio interface
• Independent audio bit clock for transmit and receive port
• Direct servo/loader interface
• Supports up to 4 MB of SDRAM and/or 4 MB of EDO DRAM
• 8 general-purpose auxiliary ports
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 I2S
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.
