Cha Chapterp1ter 1 Overview Overview 1-1 Features The DVW-M2000/M2000P/2000/2000P is a digital videocassette recorder based on the Digital Betacam format. This unit uses large scale integrated circuits for signal processing, and has a simple internal construction, allowing it to provide functionality at least equivalent to a conventional VTR in a compact (4U size), lightweight, and low power consumption design. It not only offers recording and playback in Digital Betacam format, but can also play back tapes recorded in Betacam SX format, analog Betacam format, or MPEG IMX format 1). Digital Betacam format The Digital Betacam format is characterized in that the video and four-channel audio signals of each field are recorded onto the tape with six helical tracks, at a slightly slower tape speed and three times faster drum rotation speed than the analog Betacam formats: Betacam, and Betacam SP. As for longitudinal tracks, the Digital Betacam format has a CTL track, a time code (LTC) track and a cue audio track, similarly to the analog Betacam formats. However, it does not have a channel-1 audio track, and this is a solution to expand the space for the helical tracks. Digital Betacam VTRs have a greater drum diameter than that of analog Betacam ones to ensure optimum digital recording, but their built-in time base corrector circuit enables them to play analog Betacam tapes (analog Betacam playback compatibility).
