S3 Trio64V+ Multimedia Accelerator

Overview

The S3^® Trio64V+^TM integrated graphics/video accelerator (hereinafter referred to as the Trio64V+) combines high-performance graphics and high-quality video acceleration. It incorporates an enhanced version of the 64-bit graphics accelerator core and high-performance 135 MHz true-color RAMDAC that are found in S3’s existing Trio64^TM accelerators. All display applications that require high-quality video playback (from a CD-ROM or hard drive), or live video input capability, can take advantage of the Trio64V+'s new features. The Trio64V+ accelerates/ enhances software MPEG-1/Indeo/Cinepak video playback by providing arbitrary scaling with high-quality linear interpolation and color space conversion (RGB to YUV). By performing these tasks in hardware and relieving the CPU of a substantial overhead, the Trio64V+ offers high-quality video playback with window sizes of up to 1024x768x16 bits/pixel at high frame rates.
