Ask the Experts - IT and Broadcast converge


TV-Bay Magazine
Read ezine online
Q. ‘Convergence’, specifically the convergence of IT and broadcast technology, appears to be one of those themes that endures. Why does the subject still garner so much attention in 2012? It must be 15-years since the term was first used in this context, are we not a fully converged industry?

No, I don’t think we are fully ‘converged’, far from it; and yes, it does seem strange. It is probably 20 years since the first video files were introduced in a production workflow, but the broadcast and media technology business has apparently lagged behind other industries in the exploitation of IT-based systems. That is not to say that the broadcast facilities of today are not highly reliant on 'IT' infrastructure - most control rooms have a high degree of computer driven automation, and desktop editing in news rooms is almost universal. A review of the underlying system components however, often reveals an environment comprising a number of single function 'black boxes' or software-based processes running on proprietary hardware to provide the video signal or file-based processing. From that perspective, there is a long way to go.
Q. What has caused this apparent lethargy?

There is probably no single reason. Undoubtedly, some early adopters were burned by poorly developed, unreliable offerings and partial (more cautious) implementations suffered integration headaches that yielded apparently little operational benefit. There are a few high profile digital swans at some broadcast facilities, the shortcomings of which are often highlighted by the wary as a reason to resist a more complete migration to fully IT based infrastructure.
Q. Digital Swan?
A digital swan is not (quite) a white elephant. Some early attempts at deploying IT workflows in which ‘must have’ legacy systems were retained resulted in solutions in which a number of proprietary single function devices from multiple vendors were forced to communicate through an array of gateways and format converters for the overall workflow to be realised. Thanks to a uniform user interface, an impression is created of a smooth, integrated operation whereas in reality, like a swan sailing across a pond, it is the furious paddling beneath the surface that keeps the platform operating. Therefore, failures and errors inevitably occur. Engineers and operators who have a ‘swan’ in their facility will appreciate the analogy. Their swan probably has a name. I remember a few!
Q. The issues you highlight here appear to relate to the approach as opposed to any intrinsic problem with the technologies.

That’s right. There are few technical barriers to a broadcast production implementation in which the IT components dominate. Issues of resilience or time criticality are long gone. Indeed the IT industry offers more in terms of formal service assurance at multiple levels within the technology stack than broadcast technology ever did. There are components in a broadcast/production chain that will always be highly specialised, most obviously cameras but many, perhaps most, of the downstream components need not be. As high end media production and broadcast move to digital and file-based working, new tools and systems will be required to take better advantage of the IT technology that has benefited other industries. Merely dressing legacy systems with a layer of new technology is not enough to deliver the required levels of interconnectivity and efficiency. Instead, a whole new approach to workflow and the consequent integration requirements are needed in order to satisfy the growing diversity and complexity of media business deliverables. Broadcasters and content owners need to move to products that use techniques common to other high technology sectors and try to avoid partial or compromised solutions that will deliver proportionately less benefit than a wholehearted approach.
Q. A broadcaster taking a wholehearted approach to system design doesn’t address the integration issues though.

No it doesn’t and, sadly, the integration issue remains. Vendor lock-in is a real problem in the broadcast industry, possibly more than any other technology space. Too many manufacturers take an open standard and make a subtle change to it so that it appears compliant. But on integration with a component from another manufacturer, problems arise (I’m sure most will have encountered problems with the ever-expanding flavours of the .mxf container). Manufacturers do not yet appreciate that the use of open standards is for the benefit of their customers and is now essential. Systems architects within broadcast organisations are challenged by reduced budgets and an ever-increasing number of content delivery channels; and interoperability issues characterised by manufacturer specific ‘application frame-works’ and ‘platforms’ are greatly frustrating. These situations would be anathema to a web content management system (CMS) architect. Unfortunately, such frustrations are becoming increasingly common right up the production chain.

Q. Are integration issues likely to be removed in the near future, and what will be the drivers for change?
Ultimately the resolution of integration issues - and a key driver to the migration to production platforms built on standard IT infrastructure - will be financial. These are difficult times generally, and specifically for broadcasters, who not only have to compete with a fall in overall revenue caused by changing consumption habits but the need to satisfy these changing habits with new demands on content delivery. Broadcasters need to do more with less, but expectations for production and technical quality remain high.
I expect there will be relatively few single-vendor, monolithic, production facilities deployed in the coming years. In order to achieve the required level of flexibility required of a modern production facility, a greater use of IT-based systems for signal processing as well as control/management is essential. Equally as important is the use of open communications standards/protocols and material exchange standards to achieve predictable integration. There is much frustration with broadcasters who find that they have to arbitrate between two manufacturers to ensure a complete, seamless integration, and paying for this privilege will not be tolerated much longer. Financial constraints are driving a quiet evolution, but it’s a revolution in the right direction.
Q. We expect the cloud to feature heavily at the forthcoming IBC, will cloud based computing assist the migration to the type of IT based facilities you describe here?

I expect that ‘cloud’ will continue to be a popular buzzword at IBC 2012, but this is more a supply side focus than one derived from the actual needs of production companies and broadcasters. To most in broadcast the cloud is still a nebulous term, a technology innovation searching for an application. Make no mistake, the cloud offers great opportunities for broadcasters and content owners and should be considered seriously in any technology strategy. The inherent collaborative capability it affords makes it a logical place for production to sit, and new revenue streams are also achievable. For example an archive content owner may choose to post a content catalogue on-line via a portal equipped with a simple mechanism to search, select, retrieve and deliver material. This opens up simple and low cost business-to-business and business-to-consumer revenue channels.
However, wholesale use of the cloud for production does have barriers, most notably the bandwidth requirement and related costs. Moving video content from a production office or location to the cloud for processing (e.g. editing or transcoding) and back again is cost prohibitive. The bandwidth requirement, particularly for HD content, is so expensive that the cloud model just doesn’t make sense. I expect there to be a number of hybrid solutions in which some functions such as asset management and browse editing are provisioned in the cloud, with other more heavyweight tasks such as rendering performed on the ground at the production facility. During design, systems architects should analyse which system components are best placed in the cloud and which are deployed at the production facility. The inherent use of service-orientated architecture in cloud provision is likely to drive a similar design mentality in deployed systems. This in itself will drive change.
Q. We have talked about Convergence and Clouds, what about the other C-word, Consolidation. Will market consolidation drive the take up of all IT based production platforms?

The vendor/supply side market will unquestionably consolidate significantly in the next 5-7 years (a little more slowly than in other industries – obviously!). Frankly, I don’t know many people who would take a different view. It is inevitable that some big IT supply companies will move into the broadcast space, and that will drive an increasing number of mergers and acquisitions. As to how that consolidation will manifest is not quite clear. There have been some fairly big mergers and acquisitions in recent years but they have had a tendency to be within the industry. The big IT vendors operate in relatively low risk multi-billion dollar markets and are unlikely to spend hundreds of millions, or even many tens of millions, in an acquisition that provides access to a market of only a billion dollars. In relative terms, broadcast is not a huge industry and it is more likely to be the current big beasts that have most to lose from consolidation. This may in itself drive a more open approach from manufacturers.
Q. We have talked about the on-going IT and broadcast technology convergence, how does your company Blue Lucy Media support this?

The ethos of cost-effective, software-based tools and high technical quality production values runs right through Blue Lucy Media. Most of the management and delivery team have spent the majority of their careers on the broadcaster side of the fence, so that gives us more than insight into day-to-day and longer term strategic issues, as well as the problems broadcasters and content owners face.
We have found ourselves getting more involved in overall systems integration as much as the design and build of our ‘off the shelf’ service-based video processing components, which is exciting. We have some new technical and business innovations being announced in the run up to IBC, all of which are very much focused on serving the business needs of modern broadcasters.

A Sound in Motion QA
Antonio Morais “A Sound in Motion started as a camera test for the new Sony VENICE CineAlta 6K Digital Cinema Camera and evolved into a much bigger project. The film, presented by Golpe Filmes and released this summer, was directed/edited by Ricardo Teixeira. It is a fictional story based on the way deaf people adapt themselves to daily life situations. The intent of the film is to be a positive influence in the way people think about the ‘differences in human beings’ and about issues related to social inclusion, but without turning it into something moralistic or that seems fundamentalist. Through sounds not speech, words or verbal expression we want to relay a positive message and display a clear gaze upon that difference.”

What is next after University
Ruta Kairyte

I currently find myself in between two landmark moments. A few weeks ago I was completely immersed in producing live television content, and in a few weeks time I will become an official BSc (Hons) Television & Broadcasting graduate from the University of Portsmouth. When I look back at who I was in my first year of university, I remember a shy girl from the other side of Europe, unsure at whether a career in television was the right path to take. Now, after three years of university, I can definitely say that I made the best choice of my life by choosing this degree. I’m leaving university confident and motivated, knowing that I made the right choice in study, and I really want that career in the television industry.

Investing in the Future of Broadcast Media
Clive Northen At the time of writing, the summer World Cup is providing its usual challenge to camera crews trying to televise the bright sunlight of the stadium without losing detail in shaded areas such as the covered terraces. It is a perfect demonstration of the need for high dynamic range. Several broadcasters are experimentally covering this year's tournament in 4K HDR, including the BBC which is streaming dozens of matches via its iPlayer service. HDR is also accompanied by a wider colour space, meaning millions more colours can be displayed than previously. Yet another advance is the adoption of 50p delivery rather than traditional 50i.

How to shoot the perfect lighting mix
Alan Ipakchian Advances in high-quality LED lighting over the past couple of decades might be one of the best things that’s ever happened to broadcast and cinema production. Compared to traditional tungsten fixtures, LED lights offer powerful operational and financial benefits from longer life and lower energy bills to brighter, more consistent light and greater control over color temperature. LEDs generate much lower heat and are relatively cool to the touch, meaning they can be used in much smaller rooms and studios without sweating out the talent and crew or damaging property. Plus, compared to traditional tungsten bulbs, LED lights are virtually maintenance-free and can deliver tens of thousands of hours of lamp life.

UHD 4k and HDR Picture Quality
Tobias Kronenwett And as good as it is, and as easy as it is to do, one of the raps on HDR is that some feel that it’s so bright and sharp that it looks odd, unnatural, almost harsh. It’s similar to when we did our first trials with 4K. The resolution was so high you could easily see, for example, even very minor blemishes. It’s perhaps an irony of new technology that the higher the resolution of natural objects the more artificial they tend to look. It’s often a case of capturing images with more resolution or a greater colour space than our eyes and brains can actually perceive.

What is Next for Broadcast
David Schleifer The Broadcast industry is always chasing new technology. Some of that technology is further than it appears to be, and some of it is closer to adoption than it seems. In part, early adopted technology is accelerated because of customer or business demands, and in the case of IP based environments, the driving factors are speed, cost reduction, and flexibility of workflow. To counterbalance these efficiency-based factors is a desire by content creators and customers to see more 4K HDR content on their new big screens. In some ways the push to deliver 4K workflows also makes the need to manage cost/performance even more urgent.

It produces truly stunning images, but at a price that is beyond the reach of all but those with the biggest budgets. The camera retails at a cool £100,000 (I’ll have three please) with a daily hire out charge of around £3,000 (including lighting and a technician). IDT’s OS series cameras produce equally high quality images at a cheaper price, but you’re still talking tens of thousands.

Now players like Insta360 and even GoPro with their fusion 360 camera are providing single camera, high quality solutions, enabling the masses to put out reasonable quality, certainly watchable, 360 video.

TV Futures, Tales on Location
Georgia Thirtle If I think back to last May, I was just finishing my second year at the University of Portsmouth, studying Television and Broadcasting, and winding down for the summer. Then out of the blue I got a message from my course leader, saying I might be getting a call from someone who was a location manager working for Raider productions, you know, the production company behind the upcoming Tomb Raider film, I mean, what!?

Tried and tested: DPA d:vice
KitPlus KitPlus recently took delivery of an interesting piece of equipment for review. We like our iPhone gadgets here. For us, useful iPhone gadgets started when the Olloclip lens gave us a wide angle adaptor. This was a good start, finally evolving into a proper tool when Ziess produced the Exolens system for the 5,6 & 7 series iPhones. Around the same time as the Olloclip came out we were testing the Fostex AR4i which was a very exciting development at the time. You have a portable device, that you carry everywhere with you, connected to the world but with very limited audio capabilities. A stereo interface with decent microphones was a real boon!

State of the Nation
Dick Hobbs - new

On the most recent occasion I was trimmed, my hairdresser had just returned from a holiday in Hawaii.

Where she thought she was going to die. She thought this because the state’s emergency alert system was triggered, sending messages across all available platforms, for 38 minutes, that a ballistic missile was about to strike. That, I suspect, is the sort of thing that casts a pall across your holiday.

Why did it happen? Essentially it happened because an operator selected the wrong menu item. “I feel very badly from what’s happened,” he is quoted as saying, in a somewhat mangled version of English which may at least in part explain his difficulties with menu items.
