CerifyLite Video Content Verification

Quality control of file-based video presents many challenges. Files may be received from different sources and encoded at different bitrates, formats and compression standards for SD/HD, VOD, DVD, and IPTV delivery. QC operators need to be able to check the details of each file and that it conforms to the expected template of parameters.

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 in the correct format and bitrate. At the baseband level signal levels, color space, frame format and quality must be checked to the quality of service levels expected by the Customer.

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

CerifyLite provides an objective test solution to these challenges in a convenient software package for use on PCs and laptops. It is ideal for Post Production and content houses who need to check file-based video is correct before it is dispatched.

CerifyLite is based on the award winning Cerify product which has already been selected by leading Broadcasters and Telecoms companies in the USA, Canada, Europe and Australia.

CerifyLite provides the same full range of encoding and baseband tests as Cerify V3.0. This includes extensive testing of file compression, quantization, bitrate, format tests and baseband type video tests for letterbox/pillarbox, gamut, luma, chroma, and video signal levels. Audio tests include audio peak and minimum level, audio loss, clipping, mute, and test tones on audio channels.

The test results and template databases are Cerify compatible so that a Production or DVD House using CerifyLite can use the same templates and checks before dispatching the content as the Broadcaster uses for testing with Cerify on Ingest. CerifyLite is also ideal for smaller Broadcasters with limited amounts of content to check, and as a stepping stone to the full Cerify. An upgrade path is available.

CerifyLite installs on a standard PC and can test files on the local drives. It includes detailed on-screen reporting of the file parameters and test results. It does not include the integration and automation features of the full Cerify.
