3. Introduction

This document states engineering specifications of both hardware and firmware of

DVDR520H.

DVDR520H adapts LSI DMN8652 chip, DMN-8652 is a single chip dual drive

(HDD/DVD) recorder processor. DMN-8602/DMN-8652 will be the evolutionary

product family after DMN-8600 and DMN-8650. In this sense, DMN-8602/8652 will

offer the same features as their predecessors, allow cost saving at the system level

due to integration, and offer more features at the C-Ware level.

5. Test tool introduction

There will be a testing DVD disc (for NTSC system named as 5-1 disc, for PAL system

named as 5-2P disc) as a tool when repair, below will introduce the content of the

disc

5.1 Performance Testing Procedure mainly contains 6 parts:

1). Video Signal Test

2). Speaker & Sound Signal Test

3). Music Demo

4). Video Demo

5). Karaoke Demo

6). Digital Signal Test (not usable for the time being)
