SunVideo Plus for PCI User's Guide

Chapter 1 Introduction to SunVideo Plus

The SunVideo Plus subsystem provides audio and video processing engines for a broad range of multimedia applications for Sun Peripheral Component Interface (PCI) based workstations. The SunVideo Plus subsystem provides simultaneous video and audio compression and decompression for Sun application products such as ShowMe(TM) and ShowMe(TM) TV(TM). SunVideo Plus enables you to run SunVideo demonstration programs. The SunVideo Plus architecture enables you to easily integrate:

The onboard video processor and audio digital signal processor (DSP) equip standard desktop computers, particularly those in networked environments, with the capability to run to audio/video-enabled applications for corporate training, security, authoring, telemedicine, and video conferencing.

SunVideo Plus Features

The video input to the SunVideo Plus card can be either National Television System Committee (NTSC) or Phase Alternation Line (PAL) format, and composite or S-Video video sources. Decompressed and local video can transfer across the PCI-bus to be displayed on your workstation. Audio compression is performed by the onboard DSP.

A high-speed interface to the host bus provides multiple DMA/IO channels. These channels provide flow-through for:

SunVideo Plus Software Packages

Your SunVideo Plus card comes with the following software packages:

See Chapter 2, Installing SunVideo Plus for software installation procedures.

SunVideo Plus Hardware

The SunVideo Plus card is installed in a PCI-bus slot. The card contains two Composite IN ports, and one S-Video IN port. For audio signals, SunVideo Plus also contains one port for line level OUT, one port for headphone level OUT, and one input port that can be configured through the software as either line or microphone level IN.

The following figure shows the SunVideo Plus PCI card.

SunVideo Plus supports both Composite and S-Video inputs. S-Video can provide a much sharper image than Composite video, with better color separation. S-Video uses a four-pin, mini-DIN connector, which provides separate Y (luminance) and C (chrominance) signals.
