ES4408

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(TM) 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(TM) 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^(TM) technology useful for video standards conversion. SmartStream(TM) 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 2 to control various peripheral devices. A standard I 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 ^(TM) ES4408 through the 8-bit/16-bit parallel host interface. The ^(TM) ES4408 parses the system layer and demultiplexes the audio and video streams. Audio is decoded and passed through the I 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.
