0引言家用摄录一体机(Camcorder)是由家用摄像机和录像机有机组合在一起的一种机器.1983年,日本SONY公司生产出Beta格式BMC-100P家用摄录一体机;1985年,松下公司推出磁带可以在普通家用录像机播放的VHS格式摄录机NV-M1;1989年,SONY公司将8mm摄录一体机加以高带化后推出Hi8(超8)格式摄像机,从而使图像水平清晰度从230线提高到了400线,大大改善了图像质量.20世纪90年代初期,随着数字电视技术迅速发展和高密度贴装工艺的不断完善,家用摄录一体机开始向着数字DV格式方向发展,这产生了数码摄像机(简称DV).它采用专用DV磁带和小型光学… | | |  推荐 CAJ下载  PDF下载 | | | CAJViewer7.0阅读器支持所有CNKI文件格式，AdobeReader仅支持PDF格式 | | | | Tape Format of DV and the Calculations of the Angle Between Tape Moving Direction and the Recording Track | | | BAI Dong ( Research and Development Center;Tianjin Samsung Electronics Company;Tianjin 300457;China ) | | | This article gives the explanation of the tape format recorded by digital video camcorders, it also describes the difference between sets which has differentsystems as well. On baseofthe known parameters, ituses the methodofvector synthesis to calculate the angle between tape moving direction and the recording track in PAL and NTSC systems separat-ely, so it is helpful to solve the problem of the capability that a NTSC set can not playback a PAL tape.
