FEATURE: AV IN BROADCAST
the corporate, education and live event markets are demanding full production services using cameras, video, content from laptops. They also want their event to be broadcast live to the internet, so broadcast and AV companies are changing their service offering to accommodate this.”
He adds that multi-camera
production and broadcast are becoming more affordable, both in terms of products and the delivery of content. “Companies can afford to use products with television broadcast standards for webcasting, producing content at a very high level. This means that AV companies are now able to offer broadcast as part of their services.” On the other side Kenning says broadcast companies are losing revenue and so need access to affordable, integrated AV solutions that deliver high quality in a turnkey package. “The prevalence of the internet has fuelled the convergence of these markets, changing the expectations of the clients in terms of quality, speed of delivery and audience reach,”
he continues. “Fully produced, high-quality content is required ‘now’, as the popularity of live streaming of events shows. And budget constraints mean that one company that can deliver the whole AV and broadcast solution is preferable and less expensive. Affordable broadcast-standard equipment means that the client does not always have to hire a studio or post- production facility and instead this work can be done by the AV or broadcast company.” Also in the live production
sector, NewTek specialises in compact, portable systems for broadcast, such as the TriCaster. This has been used on live broadcasts including the MTV Awards and is now being used by schools and colleges in the US to cover sports events online. Among the installation companies using the TriCaster for projects is UK- based Feltech. Sales director Nevil Bounds describes the TriCaster as a “studio in a box” with H.264 coding capability for streaming live to the web. “Live video production is now coming down to a single process,
BROADCAST AND PA AUDIO ROUTING AND MIXING IN THE KNESSET
Sessions of Israel’s parliament, the Knesset, are amplified within the debating chamber as well as being broadcast on two radio channels, IBA (Israel Broadcasting Authority) and Galatz (Army Radio), and by a dedicated television station, Knesset TV. Each of the 120 members speaks into two microphones, which are doubled up for redundancy purposes. Signals from these run into a recently installed 32-
fader Lawo mc256 MKII digital mixing console as part of a general renovation of the Knesset’s sound system. Andreas Hilmer, Lawo’s
director of marketing, says that all elements of the installation had to be “fail- proof”. The microphone feeds are received by the mc256 MKII’s standalone DALLIS I/O unit. The console itself is in a master control room and is able to continue operating
through its redundant system cores in the unlikely event of the control surface failing. A 16-fader extension module in the hall below the control room completes the mixer installation. As well as producing feeds
for the PA and broadcast channels, the mc256 MKII feeds audio logging data and is used to route translated language channels for any visiting dignitaries.
