Is the future bright for Outside Broadcast?

An Outside Broadcast (OB) truck was first used for King George VI’s coronation in May 1937, watched by around 10,000 people at home on the BBC’s television service.

Since then, broadcast has changed massively – analogue has been killed off by digital, HD has surpassed SD, and new technologies are set to change things in the next few years even more. Broadcast giant Sony helped pioneer the first 3D OB truck a couple of years ago and, at NAB this year, they announced they’re building a 4K multi-camera OB truck. NHK even trialed a modified 8K OB truck during the London Olympics 2012.

So, how has the advance of technology changed the OB market? Well, for one thing, equipment is smaller. Instead of a cumbersome rack of VTR decks, space-saving file-based servers are now the norm. The advent of multi-viewers has changed OB trucks, too – no longer do you need a wall of chunky CRT monitors – large flat screen monitors will do the job instead. Fibre cabling has also increased capabilities. Fibre means longer distances and fewer cables required. At Trickbox TV, we use the most-compact kit possible. Not only is this great for our clients, it means our kit rooms and trucks have also gotten smaller!

The cost of kitting out an OB truck or studio facility has plummeted. A few years ago, for a simple multi-camera set-up, you’d need a vision mixer, a separate multi-viewer, a video server to play the show’s opening title in on, some up-converters for that last-minute SD feed, a video scaler for that PC feed you need to get into the mixer etc. But now, one unit – a vision mixer for under £10K – can do all that! The cost of equipment has reduced considerably, part due to a fiercer market, but largely due to the cost of producing components has reduced. CMOS sensors over CCD sensors is an obvious case. The introduction of KA band and 3G and 4G video uplink means it’s easier and cheaper to transmit. Will this mean more outside broadcast? We certainly hope so.

There are some staples of television which OB will continue to dominate, such as sport and large-scale national events. But other traditional OB territory, such as music, events and festivals, can now be achieved on a smaller scale. You can get the same functionality as an OB truck with a portable production unit (PPU) but with a smaller footprint and lower budget. Trickbox TV often get asked to quote for music jobs and big events because, sometimes, an OB truck just isn’t cost effective or there’s space limitations. Plus, we work with some smaller broadcast production companies to help provide bespoke solutions for pilots or low-budget productions.

So what other emerging technologies are likely to change the face of OB? IP broadcast technology is sure to grow. BBC R&D has developed Stagebox – a camera adaptor designed to transmit everything you’d expect in a conventional triax or fibre cable (video, talkback, tally lights etc), but it’s all done over a single cat5E cable. The video is encoded at industry standard AVC-Intra 100 compression in real time. With the right software at the other end, you could ISO record all your cameras onto one storage device.

IP control is another technology changing how things are done in the field. Sony has brought out a software application which allows you to rack multiple cameras over IP. Every vision engineer must be thinking: ‘Do I actually need to get out of bed for this job? I could rack that show from home!’

GVG recently announced the launch of GV Director™, a nonlinear live production system. With built-in graphics capability, a video server, assignable buttons and a futuristic touch screen interface, mixers like these are changing the way productions are managed. GVG say the emphasis is on creativity and not on technical knowledge. As IP technologies get stronger, will it get to a point where there’s just a skeleton crew out in the field, but everything’s controlled from another location? Well, since technology is getting better, passion from people in the industry is strong and the demand is high from viewers, it’s clear the future of OB is going to get better and better.

NAB 2012 Product Launches

Well it’s been an exciting NAB show so far! There’s been some great new broadcast product launches, notably from AJA, Blackmagic Design and Panasonic.

Here’s a few of the NAB 2012 product launches that got us talking.

AJA

The T-TAP (yes an odd name) is a fantastic little bit of kit. Thunderbolt to HD SDI / HDMI. That’s all you need to say. And it’s only £160. Fantastic.

The Ki Pro Quad – a chunkier looking Ki Pro Mini – ups the ante in the 2K and 4K world and comes complete with Thunderbolt connectivity.

Here’s the AJA Ki Pro Quad brochure 

The Ki Pro Rack is also a nice addition to the Ki Pro family – it’s essentially the Ki Pro as we know it and love it – but it’s in a 1RU 19" rack-mount form factor. There’s some options already out there to rack-mount the Ki Pro but the Ki Pro Rack – with it’s dual storage docks – is perfect for flyaways, OBs and studio installs. The Ki Pro Rack also supports DNxHD as well as Pro Res.

Here’s the AJA Ki Pro Rack brochure 

Blackmagic Design 

The HyperDeck Studio has been granted the all-important and long awaited Apple Pro Res codec. A sigh of relief from every HyperDeck owner out there!

Blackmagic have also released a new version of the HyperDeck Studio – the HyperDeck Studio Pro – a 4 channel version with Thunderbolt connectivity. Interesting stuff.

And last out of the Blackmagic Design press department – and no doubt a product that wil garner much publicity – the Blackmagic Design Cinema Camera. Yes, Blackmagic Design now make cameras! We hear they’re also designing a new solar powered jet ski and a range of white goods – all with Thunderbolt connectivity. Ok that was a joke, but they really have launched a new camera!

I think the new Blackmagic Design Cinema Camera has to be seen to be believed but the specs read well and as usual, the Blackmagic price tag is extremely competitive.

Panasonic

Panasonic have announced some interesting upgrades and enhancements, including microP2 cards – a P2 card in an SD card form factor –  and a new version of the HPX250, the HPX255 which can be controlled via Panasonic’s AG-EC4 RCP – good news for us multi-camera types.

Panasonic also announced the new HPX600 camera – a big brother to the HPX371. Panasonic say it’s future proof, so when AVC-Ultra is finally rolled out, the HPX600 will be one of the first cameras to support it.
