Introduction

About Captivator Pro and Captivator ProTV

Captivator Pro is a 16-bit ISA video-in-a-window and capture

card which, when connected to a graphics card that supports the

VESA Media Channel (VM-Channel), provides:

• Scaleable full motion video-in-a-window from Composite

and S-Video input in NTSC, PAL, or SECAM format. The

video window can be displayed on top of other active

windows and mirrored horizontally.

• Capture of video clips when used with a Video for Windows™

capture application.

• Still image capture from live input using TV Snap.

Captivator Pro is available with a TV tuner, as Captivator ProTV,

allowing you to display live video directly from a TV aerial,

cable set-top or satellite decoder. Captivator ProTV has an audio

output which can be connected to an external amplifier or

speakers, and an internal audio connector which can be

connected to a sound card. It is available in three variants which

provide support for major TV broadcasting systems.

Captivator Pro and Captivator ProTV can be connected to any

VM-Channel enabled graphics card, such as VideoLogic’s

928Movie or PCI Movie.

About this guide

This guide explains how to install Captivator ProTV and use the

software. If you have a Captivator Pro, follow the instructions for

installing and using Captivator ProTV, ignoring references to the

TV tuner and audio connections. References to Captivator Pro/

TV apply to both Captivator Pro and Captivator Pro/TV.

About the Captivator Pro/TV software

The Captivator Pro/TV software, which you use with

Captivator Pro and Captivator ProTV, includes a Setup program

that installs the following program items in the VideoLogic

VM-Channel Options program group:

• Video Control Panel—which you use to configure Captivator

Pro/TV for your input and to adjust the video picture.

• TV Snap—which you use to capture still images from live

input.

• Video Window—a resizeable floating video window which

can be displayed on top of other active windows.

• A ReadMe file, in text format, that contains information that

was not available when this guide was written.

• Help—online Help files which explain in detail how to use

the Captivator Pro/TV Video Control Panel, TV Snap, and the

MCI commands that the VideoLogic Captivator Pro/TV driver

supports.

The VideoLogic Captivator Pro/TV driver, which controls

Captivator Pro/TV, supports Microsoft’s MCI video overlay

command set. This command set allows programmers to control

Captivator Pro/TV using applications developed with

programming languages or multimedia tools. The VideoLogic

Captivator Pro/TV driver also allows you to configure your

hardware without rerunning the Captivator Pro/TV Setup

program.

Introduction

8 Captivator Pro & Captivator ProTV User Guide

System requirements

Hardware

To run Captivator Pro/TV, you need a computer with a

33 MHz 386 SX processor or better, 4 MB of RAM, and a spare

16-bit ISA bus slot. You must have a graphics card with a

VM-Channel connector, such as VideoLogic’s 928Movie or

PCI Movie, installed in your computer.

To capture video clips we recommend that you use a PC with a

66 MHz 486 processor or better and a VL bus 928Movie or

PCI Movie graphics card.

If you have a Captivator ProTV and intend to use the TV tuner, it

is worth supplying a good strong signal—70dB µV for best

results. If the picture is weak and snowy, you may need a better

aerial/antenna or a booster. If you use a booster do not place it

too close to your computer. Your local aerial/antenna specialist

will be able to advise you on the optimum position for your

booster. If you need to share an aerial/antenna feed with a TV or

VCR, it is best to use a booster with two or more outputs. If you

use a splitter, make sure it is a low loss type as cheap passive

splitters usually lose too much signal.

Software

To use Captivator Pro/TV you need Windows 3.1 or above

running in enhanced mode. Microsoft recommend DOS 5.0 or

above for Video for Windows. If you are using a 928Movie you

need version 1.1.1 or above of the 928Movie software. If you are

using PCI Movie we recommend version 1.1 or above of the PCI

Movie software.

To capture video clips you need Video for Windows 1.1 and a

Video for Windows capture application.

To use TV Snap you need Video for Windows 1.1.

If you are capturing video clips to your hard disk, do not use

DoubleSpace, Stacker™ or any similar disk-doubling application,

to compress the data on your hard disk. We also recommend that

you defragment your disk regularly using the Defrag command if

you are using DOS 6.0 or later, or an application such as

SpeedDisk™ from the Norton Utilities.

What you should know

If you have never installed a card in your computer before, you

may need to refer to the documentation supplied with your

computer for instructions on removing the cover.

This guide assumes that you already have some knowledge of

Microsoft Windows 3.1 and are familiar with the Windows

User’s Guide.

If you are using Captivator Pro/TV to capture video clips and

you are not familiar with Video for Windows, it is important that

you have access to the Video for Windows User’s Guide and any

other documentation supplied with your Video for Windows

application.

If you are writing applications that use the MCI video overlay

commands, you should have access to the documentation for the

development system you are using. You may also want to refer to

Microsoft’s Digital Video Command Set for the Media Control

Interface. August 7 1992, Revision 1.0, Part # 098-37538. This

document is available on CompuServe (GO WINMM) in library

2 (MDK) in the files DVMCI1.ZIP and DVMCIT.ZIP. These

files are the same, except that DVMCI1.ZIP is in Word for

Windows format and DVMCIT.ZIP is in text format.

Introduction

10 Captivator Pro & Captivator ProTV User Guide

Handling Captivator Pro/TV

Like other adapter cards, Captivator Pro/TV can be damaged by

electrostatic charges during handling. To minimize the risk,

follow these simple guidelines:

• Keep the card in its protective packaging until you are ready

to install it.

• Just before handling the card, touch the metal frame of your

computer to discharge any static electricity which may have

built up on you or your clothes.

• Hold the card by the adapter bracket or by its edges; do not

touch the printed circuit board.

• Do not place the card on top of your computer or on any

other metal surface.

• Prevent the card being accidently touched by anyone else.

Handle the card with care to avoid damage to the fragile

electronic components mounted on both sides of the circuit

board.

Returning the registration card

All VideoLogic products come with a registration card. Please

complete and return this as soon as possible so that we can

provide you with the best possible support and up-to-date

product information.

Installing the Captivator Pro/TV card

Warning: Always switch off your computer before removing the

cover and observe the warnings specified in its documentation.

1. Exit Windows and switch off your computer, monitor and any

other peripheral devices, such as printers, connected to your

computer. Leave your computer power cable connected to the

outlet so that it is grounded.

2. Remove the cover from your computer. Refer to the computer

documentation if you are not sure how to do this.

3. Touch the bare metal chassis of your computer to discharge

any static electricity.

Changing Captivator Pro/TV’s hardware settings

This section explains how to reconfigure Captivator Pro/TV’s

base address and interrupt settings. Read this section if your

computer does not boot, Windows does not start, the

Captivator Pro/TV software is behaving in an unpredictable way,

or if you have installed another card which appears to conflict

with your Captivator Pro/TV.

Base address and interrupt clashes are two of the most common

problems that occur when installing cards. The symptoms for

each vary from one system to another, but typically:

• If you have just installed Captivator Pro/TV and your

machine will not boot or run Windows, you probably have a

base address clash.

• If you have just installed the Captivator Pro/TV software and

card and your Captivator Pro/TV applications freeze or quit

unexpectedly, or if you cannot capture video clips, you

probably have an interrupt clash.

How to change Captivator Pro/TV’s base address or interrupt setting

You can change Captivator Pro/TV’s hardware settings using the

Captivator Pro/TV Configuration dialog box, which can be run

directly from the Windows Control Panel. The following steps

explain how to change Captivator Pro/TV’s base address or

interrupt setting.

To prevent data-loss, we recommend that you quit any other

applications before changing base address or interrupt settings.

Changing Captivator Pro/TV’s hardware settings
