With the Input combo box you can select whether the incoming signal
is provided as an extra data stream via the digital audio inputs of the
DVS system (AES/EBU) or whether it is embedded in the video signal
(Embedded).
Use the Output Mode combo box to determine the output format of
the audio files, i.e. whether they should be stored as individual mono
files, stereo files or a single file containing multiple channels.
The No. of input channels combo box allows you to limit the number
of audio channels that will be available for an input of audio and re-
corded in the audio file(s). Then only the channels from the first
(channel 1) to the one specified in this field will be written in the file(s).
Furthermore, in the selection area only the limited number of channels
can be selected for an input.
From the Type combo box select the file format for the audio material
to be captured on your VTR timeline. For a list of the supported audio
file formats please refer to the “CLIPSTER Edit Tool” user guide.
Use the combo box Bit to determine the resolution of the audio files
(bit depth). The VTR task mode supports all common resolutions.
Via the combo box Sampling choose the sampling rate that the audio
data shall be recorded with.
7.1.3 Handling of the VTR Task Mode in General
The VTR task mode offers a different approach to in- or output video
and audio material in real time with the DVS software. In this mode you
can perform record and play-out operations on a single timeline capa-
ble of storing up to 24 hours of video and audio material. By using this
mode you can emulate the behavior of a logical VTR or digital disk re-
corder with the DVS system. While in its autoedit operation mode, you
can simultaneously control an externally connected device for a record
operation via RS-422 by remote.
Because of this special capability, the handling of the VTR task mode
differs in some respect from the other task modes available in the
I/O Tool. For example, as already explained earlier in this chapter, for
each VTR timeline session you have to either create a new VTR timeline
If you want to record audio in mono, the mode for mono files
has to be selected. All other modes will record the audio chan-
nels as stereo channels by default.
