Content Verification/Cerify®
Automated quality control for file-based content
Quality control of file-based video ingested from different sources, encoded at different bit rates / formats and utilizing different compression standards for SD/HD, VOD or IPTV delivery presents considerable challenges.
Cerify is the world's first fully automated system for verifying/checking file-based content prior to transmission or use. Solutions range from windows-based PC standalone workstations to enterprise-wide solutions that interface to 3rd party automation or asset management systems.
