Tektronix Cerify

Model Details

Applications
Broadcasters – Ensuring quality, compliance, and playability of audio
and video after encoding, at ingest, after editing, after transcoding,
and before playout for terrestrial, satellite, cable, internet, and
video-on-demand content
Archiving – Ensuring quality, compliance, and playability of archive
content before archiving, while in archival or prior to retrieval from the
archive.
Content Providers – Ensuring post production and aggregated content
has been correctly encoded and conforms to the required quality and
format
With Cerify You Can Ensure that Your Content
is Ready for Delivery
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
operational challenges. File-based video must be quality checked for:
Correct Encoding 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 playout server and at the
customer’s STB/playout device
Correct Encoding 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, quality levels of black frames, video
quality (blockiness), loss of audio, audio clipping, and video and audio
playtime, and verification of audio loudness and peak level
Correct Ancillary Data: Closed Captions, Teletext, DVB Subtitles, and
Timecode
Regulatory Compliance: US CALM Act, EBU R128, Canadian CC
mandates, U.K. & Japanese PSE regulations
Manual inspection can playout, watch, and listen but is subjective and
cannot look inside the encoding to check that the correct syntax and
parameters have been used. Moreover, manual inspection is prohibitively
expensive, especially given today’s increasing content growth.
Cerify solves these problems, and can be easily integrated with Automation
and Asset Management systems using the CeriTalk API; thus feeding them
with data required to automatically decide on next workflow steps or drawing
attention to the few assets that need review by experts.
The XML-based test templates can be exchanged between Cerify systems,
and applied as the definition of the required test standards between
suppliers and broadcasters to establish Service-level Agreements and
reduce costly churn (rework of content).
The Cerify Developer Community (CDC) is an ever-growing partnership
program with over 50 companies working together on integrated solutions
that work straight out of the box and deliver higher values by removing
interoperability hurdles.
