Introduction This product is a multi-purpose digital VTR that uses 1/4-inch wide tapes. It is capable of recording and playback in DVCPRO (25 Mbps) format, recording and playback in the consumer DV format (SP mode only), and playback of DVCAM tapes. This high-picture-quality VTR incorporates digital compression technology to reduce the deterioration of the picture quality and sound quality resulting from dubbing.
Features Compact and lightweight Time code This unit is a DVCPRO digital VTR which uses 1/4-inch wide cassette tapes. The compact and lightweight design makes it light to carry around and ideal for usage as a desktop viewer. The unit incorporates a TCG (time code generator)/TCR (time code reader). In addition to the internal time code, an external time code input or input signal VITC can also be recorded to the tape as a time code by this unit.

Time code/user bit Time code The time code is used when the time code signal generated by the time code generator (time code signal generator) is to be recorded on the tape, its values are to be read by the time code reader (time code signal reader), and the absolute position of the tape is to be displayed in increments of hours, minutes, seconds and frames. The time code is written in the sub-code area (data area) of the helical track.
Time code/user bit (continued) Superimpose screen The control signals, time code, etc. are displayed using abbreviations.
Condensation Condensation occurs due to the same principle involved when droplets of water form on a window pane of a heated room. It occurs when the unit or tape is moved between places where the temperature or humidity varies greatly or when, for instance: • It is moved to a very humid place full of steam or a room immediately after it has been heated up. • It is suddenly moved from a cold location to a hot or humid location.
