AmberFin’s iCR is a file-based
content ingest and transcoding
platform. Included amongst
its various options is what the
company calls UQC (Unified
Quality Control). This is made up
of a variety of tools for checking
baseband video during tape
ingest and file-based QC after
ingest and overall operator-
controlled QC (including
annotation and mark-up).
First introduced in 2011, it is
a vendor agnostic platform
that enables broadcasters and
facilities to use different QC
software systems depending on
At its core is Snell’s Hyperion,
used to check the baseband
video, and Digimetric’s Aurora,
the file-based QC offering
which is built around a web-
services API and includes hot
folder monitoring and email
notifications. Via plugins iCR can also work
with Cerify, Vidchecker and
Baton (mentioned below) as
well as MXFixer from Metaglue,
MediaArea.net’s MediaInfo and
the Pulsar product made by
Venera. Minnetonka’s AudioToolsServer
can be added to provide audio
QC and loudness tools.
ContentAgent is a file-based workflow management innovation from Root6
Technology that offers a number of tools for automating transcoding tasks. For
file-based QC and automated file correction it has three options: Cerify and
Baton (see below) and VidChecker.
VidChecker acts as a node within ContentAgent, analysing files for errors then
providing a report of its findings as metatdata. If the file has passed the checks
performed then ContentAgent can either continue the workflow or copy the file
to a UNC path for delivery. If the clip fails, the file is moved to a designated fail
folder and an automatically generated email alerts an operator to the problem.
Vidchecker doesn’t just spot the errors it can also correct them. This works for
video luma level (including black levels), video chroma (colour limit errors) and
video RGB (gamut/legality problems)
Some key features: Can process up to four files simultaneously; several
VidChecker nodes can work on multiple workstations in a networked
environment; can also check and fix audio loudness issues and peak levels.
ContentAgent also features a DPP node that automatically transcodes and
wraps files to the correct format, and injects all compulsory metadata fields.
CERIFY Tektronix’s Cerify provides content analysis for QC in a file-based environment.
It is a fully automated system that can be deployed on a standalone PC
workstation or as part of a facility-wide set-up in conjunction with other workflow
systems. Cerify will pick up on all sorts of problems including encoding and syntax errors,
format, bit rate, quantisation, frame rate, GOP length, aspect ratio, colour
format, buffer analysis and file size as well as video playtime, signal levels,
gamut, luminance, chrominance, black frame detection, blockiness, freeze frame
detection and field order.
Some key features: Automatic objective testing; user definable test templates;
logging of all testing and results; multi-user browser interface; video server
and automation integration; user definable quality levels; audio loudness
measurements (including peak and minimum levels, audio loss, clipping, silence,
mute, test tones).
Some key features: graphical
view of automated QC results;
‘Cut and Splice’ engine for
simple editing tasks; ‘Light’ QC
checks at multiple points in the
workflow. Amberfin is also responsible for
the iCR-500 DPP, a workstation
specifically designed for the
creation and preparation
of AMWA AS-11 compliant
assets in accordance with
the DPP spec. This product
combines ingest, transcode
and playback functionality with
metadata entry and validation,
QC review and mark-up.

BATON Interra Systems’ Baton is an automated content verification and QC application.
Like the others it checks a whole host of things including, but not confined to:
content layout, VoD compliance, play time, file size, packet size, number of
audio/video streams, ARIB specifications and AS02 compliance as well as frame
rate, bit rate, frame size, aspect ratio, duration, resolution and more.
Some key features: web based; rule-based smart folders for content aware QC;
audio loudness and metadata correction; web services API to integrate with
media servers, transcoders, MAM and archives.
