  1. LMD-4588 QRE 经验交流 主讲:赖平涛/ATS 2004-11-27 Quality Reliability Engineering

  2. 一、视频响应---解析度Disc: TDV540 Title2 Chapter9---multi burst.TDV540 Title2 Chapter15---sweep.Frequency:0.5MHz---6.0MHzError range:+1dB------4dB Quality Reliability Engineering

  3. Action sample Quality Reliability Engineering

  4. standard model Quality Reliability Engineering

  5. 二、刮碟分析TCD-732A刮碟(Vertical deviation test CD)1.参数:碟片中心孔的直径:15.00±0.10mm碟片厚度:1.20(+0.30/-0.10)mm碟片直径:120.00±0.30mm面振范围:1.00±0.05 mm设计标准:3.20mm UP SIDE +0.5±0.05mm DOWN SIDE -0.5±0.05mm Quality Reliability Engineering

  6. 三、防拷贝技术测试 1、CGMS(Copy GenerationManagement System)    管理数字录像产品的系统 CGMS信息内置于输出的视频信号中。 CGMS工作时,进行拷贝的设备必须能识别 CGMS.模拟标准(CGMS/A) 对NTSC21线数 据进行编码。这是一个“串行”的拷贝生成管 理系统(SCMS),可以防止拷贝。 Quality Reliability Engineering

  7. LINE-5 LINE-17 LINE-259 Quality Reliability Engineering

  8. LINE-5 LINE-17 LINE-259 Quality Reliability Engineering

  9. 2.MARCOVISION 以美国八大影业公司所组成的DVD联 盟对DVD制定了很多规定,其中由Macrovision公司设计的DVD讯号管制,包括DVD放影机、显示卡都必须通过Macrovision认证,否则讯号在输出时将被切断,因此若只是拷贝光盘或档案,甚至透过讯号线转录,都无法取得正常的影像。 Quality Reliability Engineering

  10. Quality Reliability Engineering

  11. 3.区域码控制: 每个地区所发行的DVD DISC只能以符 合该地区区域码的DVD PLAYER来播放。 Quality Reliability Engineering

  12. 4.CSS---Content Scramble System 数据干扰系统 目前市面上大多数刻录软件,就算支持 DVD刻录功能,通常也无法解除上述的保护 措施,包括:Easy CD Creator、Nero Burning-Rom,遇到有保护设计的光盘时,还 会提醒使用者无法复制。 Quality Reliability Engineering

  13. 四、27MHz晶振频偏测试  标准:<15PPM   超标------DVD PLAYER输出无彩  原因:27 MHz匹配电容没配好 D/A时钟频率=384*Fs Fs:CD=44.1kHz DVD=48kHz CD SCKI=16.934400MHz DVD SCKI=18.432000MHz Quality Reliability Engineering
