4.4 Accessing DVS Disk Recorders

4.4.1.

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‘.
