Broadcast Test and
Measurement Update
Contributing Editor David Kirk has another
fresh look at the developments in the field
of and measurement and monitoring...
he transition from owned
hardware and software to pay-asyou-go
media services is increasingly
evident in many areas of business,
not least the broadcast sector where
it offers an alternative to high capital
expense during the early years of a
production company, post house or
media channel. Pay-as-you-go offers
insulation against ever evolving
technical standards, file formats,
compression algorithms and interface
options. Most significant of the latter
at present is the increasing adoption of
IP infrastructure in what was once an
SDI-dominated market. The following
survey looks the impact of these and
other influences in the field of test and
measurement.
Audio Precision's latest APx500
audio measurement software, version
6.1, adds new measurement tools
T
for testing loudspeakers, headphone
drivers and microphones. These
include facilities for detecting
rub, buzz and air leak defects in
loudspeakers.
Rub-related
noises
occur when the speaker cone is offcentre
or canted. Buzz defects occur
when loose particulates are trapped
in the gap between the voice coil and
the cone. Air leaks are commonly
perforations in the speaker surround,
imperfectly sealed dust caps, or other
unintentional gaps in the housing or
cabinet. AP uses high-pass tracking
filters to remove the
fundamental
Audio Precision's APx500 Flex Audio Analyzer
signal and detect defects as excursions
in the residual waveform's crest
factor or peak ratio. Also new is AP's
Fast Sweep test signal. Advantages
of Fast Sweep are lack of transient
ripples at low or high frequencies,
the ability to sweep from low-to-high
or high-to-low frequency, support
for measuring harmonics above
the 20th, and precise control of the
number of discrete points used in
measurements. " While version 6.1 is
officially a minor release, and thus a
free upgrade to any analyzer licensed
for version 6.0, it delivers significant,
new capabilities, especially for those
involved in the design, manufacture,
and test of speaker drivers and
any product incorporating them, "
said Audio Precision's General
Manager Daniel Knighten.
ancillary
Release 6.1 is compatible with all
analyzers in the APx500 Series.
Software upgrades are available for
owners of existing APx analyzers, with
options for upgrading from v4.x or
earlier to v5.0, from v4.x to 6.0, and
v5.0 to v6.0. Software maintenance
contracts are available for instruments
licensed for the current release (v6.0),
entitling the analyzer to one, three,
or five additional major software
releases depending upon the contract
purchased.
Bridge Technologies has added new
HDR capabilities to its VB440. These
allow monitoring and visualisation
of HDR and SDR production outputs
from any internet-connected location
using only an HTML5 browser. The
VB440 can now identify the type of
coded stream coming in, recognising
standards such as HLG, PG and S-Log3,
through automatic recognition from
data
Bridge Technologies' VB440
or NMOS signalling
data. It can also be switched manually.
The user is then able to access any of
the existing wide range of waveform
scopes within the instrument and apply
them to the HDR stream. An HDR CIE
Chromaticity scope has been added.
HDR is still a transitional standard that
has not fully penetrated the market
so the VB440 also facilitates data
and image visualisation according to
SDR parameters. The VB440 can give
a visual preview of an HDR output
image through a non-HDR compatible
browser. This is achieved by converting
the HDR image into the sRGB
colourspace of the browser, simulating
what the HDR output will resemble
for the viewing audience " With the
rise of HDR-ready TVs, viewers are
becoming
increasingly
discerning
in relation to image quality, " says
Bridge Technologies' Chairman Simen
Frostad. " This presents a problem in
the field of broadcast production
