Product Description

Overview

The S3® Trio64V+TM integrated graphics/video accelerator (hereinafter referred to as the Trio64V+) combines high-performance graphics and high-quality video acceleration features with the capability to directly interface to live video and MPEG-1 peripherals. 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 existing Trio64TM 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. The Trio64V+ has an S3 Scenic HighwayTM interface that provides a direct interface to MPEG-1 audio/video decoder devices and live video digitizers to attain full-motion video.

S3 Streams Processor

The S3 Streams ProcessorTM allows the mixing of three separate display streams. The primary stream can be RGB data of any color depth. The secondary stream can be RGB or YUV (video) data of any color depth. YUV data is color space converted to RGB. The third stream, the hardware cursor, overlays the other two streams.

Arithmetic blending of a primary graphics stream and secondary graphics/video enables dramatic transition effects for game applications. Color and chroma keying allow opaque or transparent overlays of one stream on the other. Hardware-assisted double buffering of both primary and secondary data streams is also provided to enable high-quality "tear-free" playback.

The Trio64V+ also enhances game acceleration, with support for a sprite plane where sprites are actually rendered into a sprite plane memory. Sprites can be overlaid onto the background without saving and restoring the background.

The Streams Processor is located in the pixel datapath between the display memory and the RAMDAC that drives the RGB signals to the monitor. One of the key advantages of this architecture is that it permits processing of pixel streams on the fly at display refresh rates. This eliminates the need to first write back processed (scaled or color-space-converted) data into the frame buffer before sending it to the RAMDAC. This saves memory storage and memory bandwidth.

The Streams Processor also enables simultaneous display of graphics and video of different color depths. For example, it is possible to display 24 bits/pixel-equivalent video on top of an 8-bit graphics background. This also saves memory bandwidth and storage capacity while permitting higher frame rates because of reduced bandwidth requirements.

In addition, if an opaque rectangular window of one stream is overlaid onto another background window of a second stream, it is not necessary to fetch and refresh the hidden pixels. This provides additional memory bandwidth savings.

S3 Scenic Highway

The S3 Scenic Highway interface directly connects to MPEG-1 audio/video decoders such as the S3 Scenic/MX2TM MPEG-1 audio/video decoder and the C-Cube® CL-480 as well as video digitizers such as Philips® 7110/7111. This provides easy implemen-tation of MPEG-1 or digital video daughtercards that directly plug into the Scenic Highway connector or, alternately, ISA cards, where a ribbon cable is also necessary.

The Streams Processor and Scenic Highway are tightly coupled to provide optimal live video playback. The hardware automatically switches capture and display buffers without software intervention.
