1. Overview

1.0 Introduction

Skymicro’s Merlin 2003 DV and MPEG-2 Recorder and Dual Stream Decoder board is a complete video capture

and playback solution in a single half-sized PCI card. It is ideally suited for applications such as digital video

broadcast, video distribution applications, authoring, and nonlinear editing.

The Merlin 2003 DV and MPEG-2 Recorder and Dual Stream Decoder includes all the software necessary to

record, compress, process and play back audio and video clips in DV and MPEG-2 formats. The audio and video

are treated separately so audio can be added to video at a later time or vice versa. The Merlin board can also play

audio and video at variable speed. Merlin has many elaborate Non Linear Editing features; one of these is to allow

you to play back two streams of video and then transition from one to the other using many selectable transition

effects. By using a highly sophisticated processor all this can be done in Real Time. Moving from any frame to any

other frame in a video clip is a snap with Merlin. All you need to do is enter a frame number or move a slide control

and you are instantly at the desired frame. You can even give Merlin a play list to specify all the clips you wish to

play, and all the transition effects you wish to occur between your clips with starting and ending frame numbers,

and Merlin will do the rest. Merlin can even convert files to and from DV, MPEG-2 and many other picture and

video formats.

2. Getting Started

2.0 System Requirements

Please make sure your system meets the following requirements before using the Merlin 2003 board.

-Pentium 600MHz CPU or a CPU with higher performance.

-Windows XP, Windows 2000, Windows NT 4.0, Windows 98, or Windows Me Operating System.

-One available Bus Mastering PCI slot (two slots if you are installing a two board configuration).

-At least 128 Megabytes of system DRAM.

-A high performance Disk Drive or Disk Array for storing Audio/Video files.

-At least 10 Megabytes of available Disk space for the Merlin Application Software.

-Approximately 10 to 100 Megabytes of Disk space for each minute of video you plan to store.

-An output monitor or overlay graphics card (such as the ATI All in Wonder) to view video output.

2.2 Preparing Your System

Before you install your Merlin 2003 Board there are a few guidelines that will help you achieve optimum video

performance. It is important to make sure that there are no other programs running while recording and playing

back video. You should check your system and make sure there are no screen savers, anti-virus programs or

fax/modem utilities that can use up CPU and memory resources. It is also important to make sure your disk drives

will run efficiently. The best way to do this is to defragment your disk drives frequently. If you do not own any

deframentation software, we recommend that you purchase Norton Utilities for Windows from Symantec. This

software package includes a defragmentation program for the most Windows Operating System. Another way to

optimize your disk performance is to have a dedicated partition for Audio and Video files. Here is a list of

recommendations on how to optimize the performance of the Audio/Video (A/V) partition that you use:

-Try not to store anything other that Audio/Video files on your A/V partitions.

-Defragment your A/V partitions frequently.

-Try to use NTFS (WindowsNT, Windows 2000/XP File System) partitions for A/V files.

-Try to use dedicated drives to store your A/V files.

-If possible use a high performance storage system for your A/V files.

A high performance storage system can mean a variety of things. It can be as simple as using a single high quality

IDE, SCSI or Fibre Channel disk drive to using a high performance Disk Array tunes for optimum video

performance. There are lots of storage system options available and lots of companies to choose from. With

MPEG-2 very high quality video can be achieved with a less than 15 megabit per second video stream. This is

easily sustained on even the cheapest IDE drives available today. However, if it is desirable to play multiple video

streams at fast forward play speeds that were recorded at 50 megabit per second record rate, you may want to

consider looking into a higher performance storage system.

3. Installing the Hardware

3.0 Computer Installation

To install the Merlin 2003 Board in you computer follow the directions below:

1. Discharge any electrostatic charge that you may have accumulated by touching the metal case of your

computer.

2. Switch off the computer and disconnect any cables attached to your computer, including the power

cord.

3. Loosen any screws required to remove the computer cover and remove the cover.

4. Position the computer so that the PCI expansion slots are visible. It should look something like this:

5. Select a Slot to install the Merlin board. It is best to space boards 2 apart at first and then fill the

spaces as you use up the slots. This distributes the heat in your computer better.

6. Remove the Slot Cover corresponding to the slot you wish to use.
