Security
The ARRIQCP is equipped with an invisible watermark that is embedded into
the picture. In case of unauthorized copy, the date, time and location of a security
leak can be fully traced; a visible watermark is also superimposed over the picture
for added security. A KDM for the ARRIQCP is still required for playback of en-
crypted material.
DCP and KDM Compliance Testing
In case a DCP is ingested to the system a validity check is performed, metadata
in Composition Playlist (CPL), Packinglist (PL) and Assetmap is parsed and all links
to track files are tested for missing links. Furthermore an XML schema test can be
performed and KDMs checked for JPEG Interop and SMPTE standards compliance;
for more time consuming tests, like JPEG2000 Interoperability, the user decides
what tests to perform. Users are able to create sets of tests to be performed on the
different assets of a DCP. These tests might include comparison of aspect ratios
recorded in the CPL and the JPEG2000 file, JPEG2000 file size checking, PKL
signature test, PKL Assetmap matching, message digest test, CPL signature test,
track file reference test, essence encoding consistency test, duration consistency,
and encryption key ID test. Status messages of failed or passed tests are collected
and stored for later review or exported for reporting or communication purposes.
Easy Operation
Job Management allows a clear overview of currently processed and pending
jobs. In case of urgent tests a complete ingest of content could be too time con-
suming, so it is possible to perform an immediate playback for “emergency screen-
ing”. If the content is on a SATA swap hard disk, movies can be played back in real
time. For easier communication between facilities an updated CPL can be exported
to disclose particular changes that should be performed for a valid package.
