DV TERMINAL
This terminal is used to input/output video and audio data on digital video equipment. Because the video and audio data is sent through the DV cable as digital signals, there is practically no deterioration in video and audio quality after copying. In addition, because the hardware automatically determines the direction of flow for input and output signals according to the state of the unit, there is no need to change the connections around when switching between input and output, as is the case with conventional AV cables.
In addition, the DV terminal on the
Copying, Assemble, Video Insert, and Audio Insert.
(Such a configuration does not permit AV Insert, Audio Dubbing, or Audio Mixing. AV cables must also be connected.)
The following functional differences exist when the recording unit and the playback unit are connected through the DV terminal, as opposed to when they are connected through the audio and video sockets:
≥The original sub code data (date of the recording, photoshot index signals, etc.) on the playback unit is copied as is on the recording unit.
(Time codes are not copied.)
≥The audio is recorded in the same mode (12bit or 16bit) on the recording unit as it was on the playback unit. (If you want to change the audio recording mode, the units must be connected through the audio and video sockets, not the DV terminal.)
≥No audio is output while searching with the Jog Dial/ Shuttle Ring.
≥When playing a tape that was recorded with two audio channels (main and sub; from a bilingual broadcast, for example), both the main audio channel and the sub audio channel are output, regardless of the audio select (main/sub) setting.
≥Horizontal sway may appear at the bottom of the screen for video input from the DV terminal, but this has no effect on the recording.
Time code
Time Code signals are time data that is recorded on the tape. The time is expressed in units of hours (h), minutes (m), seconds (s) and frames (f) (25 frames/ sec). Time codes are recorded concurrently while the video is being recorded. If a recording is made continuously from the beginning of a tape, the Time codes can be used to determine the absolute position of video and audio recorded on the tape.
When you first record on a new (previously unrecorded) cassette, the Time codes are also recorded, starting from zero. If you start recording in the middle of a cassette that has already been partially recorded, and you start where the previous recording ended, the Time code units continue from the ending unit of the previous recording. However, if you start recording in the middle of a tape after a blank section of tape, the Time codes again start from zero.
Unless the Time code is recorded continuously from the beginning of the tape, precise editing may not be possible. To ensure that the Time code will be recorded without interruption, we recommend that you use the Index Search function before starting to record a new scene.
Frame
This is a Time code unit. One frame is equivalent to 1/25 of a second. (Refer to the description of Time codes.)
Tape Counter (Linear counter)
As opposed to the absolute value Time codes (refer to the explanation of Time codes) that are recorded on tape simultaneously when video or audio material is recorded, the tape counter (linear counter) is time information that can change units. The tape counter is reset to zero each time a tape is loaded/ejected, and can also be reset to zero at any other time by pressing
RESET.
3D-DNR (3-Dimensional Digital Noise Reduction)
To activate the 3D DNR function, press the 3D DNR button, so that the “PB DNR” or “REC DNR” appears on the VCR display. 3D DNR function will now reduce the noise during playback or recording.
Use of “REC DNR” during recording reduces the shaking and distortion that occur during the recording of analogue tapes so that pictures with a high picture quality are obtained. Use of “PB DNR” when playing back pictures from an analogue device reduces the amount of noise, thereby making it possible to view pictures with a high picture quality.
≥During playback, the picture may become the afterimage. In such a case, cancel the 3D DNR function.
