DVD/MPEG-2 PCI Playback Card Solution

Overview

Sigma Designs EM8300 is a digital video decoder chip that integrates the PCI interface, video scalar, video color processing and decryption logic on a single chip. It is designed for high-quality, DVD/MPEG-2-compliant digital video playback on a multimedia PC.

EM8300 integrates all the features you need to implement a PC-based DVD and an MPEG-2 digital video playback. The integrated video scalar in EM8300 can scale horizontally and vertically with bilinear interpolation filtering that can display video frames up to 1600x1200 display resolution. The video filtering and scaling implement Bob and Weave de-interlacing algorithms. It also provides digital controls such as brightness, contrast and saturation for sharp and clear video image quality at any size.

EM8300 also integrates key hardware for DVD movie- and ROM-based MPEG-2 video titles. This includes an integrated digital decryption logic for DVD encrypted movie playback. Sub-picture data processing and alpha blending for on-screen display menus mix digital video with interactive menus, graphics, and text.

The YUV video output port of EM8300 can interface directly to video encoders, video input ports, and analog overlay devices. The built-in serial audio output and S/PDIF encoder allow direct digital or optical output of AC-3 5.1 channel audio stream. The serial audio output can directly be connected to stereo audio DAC for PCM-encoded MPEG-2 2-channel audio.

The EM8300 DVD/MPEG-2 includes Sigma Designs' DVD-Station, a full featured application that incorporates all the DVD navigation control features. DVD-Station controls integrate all the features found in stand-alone DVD players. DVD-Station has simple VCR-like control buttons to choose video title, track, playback, pause, stop, forward and backward variable speed visual search, slow motion, next and previous chapter track, search, and title selection. DVD-Station also integrates DVD navigation features such as on-screen interactive menus, sub-picture controls, and sub-titles display selection.
