With Cerify® You Know Your Content is Correct Before it is Transmitted or Used

Quality control of file-based video that may be ingested from different sources and encoded at different bit rates, formats, and compression standards for SD/HD, VOD, and IPTV delivery presents considerable challenges. File-based video must be quality checked for:

Correct Syntax: At the digital level the audio and video must be correctly encoded without errors in accordance with the compression standard, so that it plays out correctly at the customer’s STB/playout device.

Correct Parameters: The audio and video bit rates, GOP structure, video color-space, color depth, frame size, frame rate, aspect ratio, and quantization levels must be correct.

Correct Baseband and Quality Levels: The analog parameters of signal levels, luma, chroma, gamut, and quality levels of black frames, video quality (blockiness), loss of audio, audio clipping, and video and audio playtime.

Manual inspection can playout, watch, and listen but is subjective and cannot look inside the encoding to check that the correct parameters have been used - for example, have the packet size, GOP structure, and bit rates been set correctly?

Cerify® 200 solves all these problems, and can be easily integrated with Automation and Asset Management systems using the CeriTalk API. It is the world’s first and leading automated system for checking/verifying file-based video content prior to transmission or use.

Cerify® 200 uses the latest server technology providing high throughputs and processing speeds. Each test unit can test four files simultaneously and units can also be clustered to provide high throughputs and redundancy.

Testing is in accordance with user-defined templates, and can run fully automatically 24/7. Jobs can be assigned different priorities depending on how quickly they need to go to air.

Cerify® logs errors as the content is checked, can inform automation systems, move files depending on the results, and e-mail users and content encoders detailing the errors found.

CeriTalk API provides complete integration with automation and asset management systems.

Multiple Cerify® Media Test Units

Cerify can be used as a single unit, or alternatively multiple Cerify Media Test Units can be used on a network, providing enhanced throughput for multiple content channels, and load redistribution and redundancy in the event of failure.

  • The testing of files is controlled by a Cerify Supervisor Unit, which allocates test Jobs to the Media Test Units (where there is only one Cerify unit, it acts as Supervisor and Media Test Unit).
  • User access is through a standard Web browser from any location on the network.
  • Integrates with, and can be controlled by, Automation and Asset Management Systems using the CeriTalk API.
