Having spent the last 30 years working in broadcast television and live event production in a variety of technical roles it has become plainly obvious over the last few years that we have lost some of the benefits working with the traditional PPUs with OCPs and CCUs. There are so many small HD and SDI vision mixers available nowadays since the launch of the Sony Anycast about ten years ago and more people are using these mixers for their events. The one thing that has gone by the wayside is talkback and tally. The loss of talkback has been solved through wireless systems and microwave links provide wireless video signal, but until now a tally light system, vital for the operator in situations where hearing the director due to excessive noise is simply impossible, has remained undeveloped.

I tried to source a wireless tally system, but found there was no such product available on the market so I decided to invent my own. The product has been developed over the last 2- 3 years and has been used on broadcast and production events with great success and we now have the wireless tally system, Tally Ho! in commercial production.

Tally Ho! gives a red light front and back on the camera and you also get a green preview light on the rear if used with certain vision mixers. More and more vision mixers will be able to give you this feature as their software is upgraded. Currently Roland mixers are able to offer you this unique feature which has proved to be extremely useful as it allows the camera man to see when he is in preview without relying on being able to hear the director. The green light illuminates in preview, turning to red when live, thus avoiding those awkward moments when going live occurs at the exact moment that the operator decides to change shot. The system consists of a Transmitter (TX) and power supply, together with a maximum of thirty two battery-powered Receiver (RX) modules. The RX units are charged with the (TX) power supply.

Each camera used in a production is fitted with a wireless receiver, and the transmitter is connected to the vision mixer or editing unit. Each time the vision operator selects a camera in either preview or live selection on the mixer, a code is transmitted to the corresponding receiver which in turn illuminates a transmission tally light on the receiver. This indicator is clearly visible to both the camera operator and the subject/presenter.

The TX unit is mains powered and sits alongside the mixing desk. The RX units mount onto the camera hotshoe although it can be attached in different ways depending on requirements.

Increasing Diversity in the UK Indie Market
Sam Addo

London director Sam Addo tells us more about how he aims to change the status quo when it comes to onscreen diversity with his new feature, Cards on the Table.

“Over the past thirty years, filmmakers have made movies telling a wide range of stories, however, in my humble opinion, those with disabilities, from the LGBTQ+ community and or those from ethnic minorities remain underrepresented on screen. For example, it is rare to find a film where the lead character has a disabil ity, and that underrepresentation is worrying.”

Keeping Pace with the Content Revolution
Kevin Fitzgerald These are uniquely challenging times for broadcasters and their technical teams. Not only are they having to negotiate the move to IP-based infrastructures and the introduction of new formats and techniques such as 4K and HDR, they are also having to generate more content than ever before to support OTT and web services as well as traditional linear broadcast.

State of the Nation - Getting Connected
Dick Hobbs - new We are all familiar with statistics about the growth of the internet. Cisco’s latest report, for instance, says that global IP traffic is increasing at 26% a year, and will reach 4.8 zetabytes a year by 2022. The number of connected devices will be three times the world’s population by the same date.

Original KVM or KVM over IP
Jochen Bauer Will the technology used in broadcasting solely consist of IP devices? For years, IP has been entering all areas of life. Especially control room applications as they are typically deployed in broadcasting benefit from the IP revolution in many ways. But an “IP-only broadcast world” is not yet here. Nevertheless, the trend clearly moves towards IP transmission, even though a large part of content production still uses traditional transmission paths. And therefore we continue to live in a hybrid world, using both original and IP-based technology. KVM experts Guntermann und Drunck still rely on both original KVM and KVM-over-IP™ to be able to offer their customers the best of both worlds.
