1. Introduction

The Philips ISP1581 Hi-Speed Universal Serial Bus (USB) MPEG2 Encoder Reference Kit is a development tool that consists of an MPEG2 encoder demo board, firmware source code for the onboard microcontroller, and a complete set of documents. This kit guides you in how analog video signals from various sources (S-Video or composite signal) are converted to digital video signals, which are then compressed to an MPEG2 bitstream by the onboard MPEG2 encoder chip. The bitstream is transferred to the PC through a high-speed USB pipe. Th is kit is very suitable for video capture card applications and digital video (DV) applications.

This document explains the use of the demo board in terms of jumper settings and connector pin assignments. A basic board testing procedure is also provided.

2. System Requirements

• Requires a PC with the following configurations:

o An 800 MHz Pentium III (or equivalent) CPU or faster o A Video Graphics Adaptor (VGA) card with video resolution of 800 x 600 or greater

ISP1581 Hi-Speed USB MPEG2 Encoder Reference Kit

o A sound card o A hard disk with 300 Mbytes or greater free space o System memory size of 128 Mbytes or greater o A Hi-Speed USB Host Controller o Microsoft Visual C++.

• Operating system supported: Microsoft

3. Connection Diagram

To perform a functionality test, an Audio/Video (AV) source device is required. Its audi o and video output signals should be connected to the audio and video input jacks of the demo board, respectively. See Figure 3-1.

5. Device Driver and Application Software

5.1. Introduction

The device driver and the application software are stored on a source diskette in mpegtestsuite.zip. The source diskette contains the following files:

• mpegtestsuite.zip

• readme.txt

Unzip mpegtestsuite.zip, you will obtain the following directory structure:

<drive>:\Application\

•

<drive>:\Driver\

•

<drive>:\InitFiles\

•

<drive>:\Decoder\

•

5.2. Preparing for Software Installation

Create a directory called “C:\philipsMpeg\”1, and move the following three unzipped directories to this directory.

<drive>:\Application\

•

<drive>:\Driver\

•

<drive>:\Decoder\

UM10016_3

ISP1581 Hi-Speed USB MPEG2 Encoder Reference Kit

Copy files in directory “

<drive>:\InitFiles\*.*” to directory “C:\philipsMpeg”. By default, the

application software searches initial files under directory C:\philipsMpeg and, therefore, whenever the device is initialized, the application pro mpts for the current path of the file.

Note: Copy file MSVCRTD.DLL from the Application directory to the WINNT\System32\ directory, if the file is not present on your PC.

5.2.1. Installing the Device Driver

Connect the device to the system. When the system prompts for the INF file, redirect the system to the C:\philipsMpeg\Driver directory and load the driver by using the INF file.

5.2.2. Installing the Decoder

To install the supplied decoder, run the “register.bat” DO S batch file. This file can be found in directory C:\philipsMpeg\Decoder. The decoder consists of eight software components.

The contents of the register.bat batch file are:

• regsvr32 pim2null.ax

• regsvr32 mpgdec.ax

• regsvr32 mpeg2dmx.ax

• regsvr32 pva_dmx.ax

• regsvr32 mlcom.ax

• regsvr32 windivx.ax

• regsvr32 ball.ax

• regsvr32 mpg2splt.ax.

It is strictly recommended to name the directory as philipsMpeg and must be located under the C drive.

Philips Semiconductors

When running the DOS batch file, carefully check messages (see Figure 5-1) to ensure that all components are successfully loaded.

5.3. Using the Application Software

This application software handles board initialization and MPEG2 stream transfer. Before running this application, make sure that all the cables are connected and A/V sources are present. For details on connection, see Section 8.

Figure 5-1: Contents of the register.bat Batch File

The initialization process is explained in the following sections.

5.3.1. Board Initialization

You can start the application software either by double-clicking the MPEG.exe1 icon present in the C:\PhilipsMPEG directory, or by double-clicking the MPEG.exe icon on your desktop if you have already created a shortcut.

To initialize the board, select a proper TV standard under the Capture menu. For example: Initialize PAL (see Figure 5-2) or Initialize NTSC (see Figure 5-3). S-Video is a default video input source.
