4.4 Accessing DVS Disk Recorders
Together with ALICE comes the possibility to directly access
DVS HDTV and SDTV disc recorders. Direct access to disc
recorders is also possible via the command line interface
(CLIF).
The direct frame access uses the DVS API, and does not
need the DVS virtual file system to be installed. Frames
are accessed as raw YUV data, and converted to RGB
by the ARRILASER software. The conversion follows the
DVS SMPTE274cgr matrices, thus converting the video
save range into full 16 bit range.
Since the conversion is done at a very early processing
stage, the images are seen by the ARRILASER software
as 16 bit RGB images. They also require 16 bit LUTs for
recording, regardless of being stored as 8 or 10 bit
YUV on the disc recorder. Also, YUV data exported
from the disc recorder as YUV16 can be read, if given
the file extension ‘
.yuv16
‘.
4.4.1 Browsing Disc Recorders
To make disc recorders visible in the sequence dialog
panels, define their host names or ip addresses in the
‘
preferred disc recorders
‘ section within the ‘network‘ tab
in ALICE preferences. The entry is a comma separated list
of the disk recorders. Disk recorders can be specified by
ip addresses or by name. If specifying names, make sure
there is a domain name server entry for the disc recorders,
or list them in the windows host file
‘
c:\winnt\system32\drivers\etc\hosts
‘.
