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^TM  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^TM 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^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 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 I² S interface 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 I² 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.
