Tektronix Debuts Verification System for Digital Video Content

Tektronix introduced an automated system capable of verifying the quality of file-based, compressed digital video and audio content prior to transmission or use. The Tektronix Cerify platform tests all aspects of stored compressed video and audio quality to ensure it meets the system parameters, formats, resolutions, bit-rates, video/audio quality levels and compliance/correctness to a wide-range of specified video and audio standards.

Controlled via a standard web-browser interface, the Tektronix Cerify system comprises one or more rack-mounted media test units. Multiple Cerify Media Test Units are controlled by a Cerify Controller and are used on a network, providing enhanced throughput for multiple content channels, load balancing, and automatic re-distribution in the event of failure of any component. Cerify works with almost all video standards and formats including SD, HD (720p, 1080i/p), 24 fps, NTSC, PAL, SECAM, encoded in MPEG-2, H.264/AVC, MPEG-4, VC-1 or H.263 video format with MPEG-2, AAC, AACplus, HE AAC or AC3 audio. A "CeriTalk" application programming interface (API) is under development for integration of Cerify with broadcast automation systems.

Cerify is available in various configurations, including the CYC100 for single-unit installations and the CYS100 plus CYM100 for Cerify solutions including enhanced throughput for multiple content channels, load re-distribution and automatic redundancy in network "cluster" configurations.
