What is Serial Communication
|
 |
Don’t get me wrong - the advent of IP technology has done wonders for the broadcasting universe, especially here in Special Cams land where changing a setting could have involved a rather long walk and climb to a remote camera location! Nevertheless, this said, I still feel that serial communication is a huge contender - not only just in the realm of odd robotics systems, but also across broadcast in general.
In this article, I will walk through the very basics - introducing a few different types of serial and how they work.

UHD 4k and HDR Picture Quality
|
 |
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
|
 |
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. |

How to shoot the perfect lighting mix
|
 |
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. |

Delivering on the 4k Promise
|
 |
It’s happened. Consumers are demanding 4K UHD content. They have the TVs, smartphones, tablets and other devices they need, and with much of Netflix and Amazon original content in 4K, as well as sports coverage from BT and Sky, consumers have tasted the future of content quality and are hungry for more. But broadcasters need not worry if their customers have enough bandwidth to receive 4K content - the solutions are ready to make 4K distribution a reality. New viewers are waiting if you’re ready to get to them first. |

TVFutures : Bouncing Back
|
 |
When I arrived at the University of Portsmouth three years ago, I would never have thought in my wildest dreams I would end up where I am now. My time at university has been eye opening, informative and fun. Of all the lessons I have learned in the past three years, resilience is the one that has taught me the most. Starting out in the television industry is hard. Like many others, I’ve applied for graduate job after graduate job and been pipped to the post and rejected many times. I have also started projects and been faced with a variety of unexpected setbacks. Yet, my drive to enter this industry remains just as strong because bouncing back is the joy of resilience. |

Slow Motion Video Techniques
|
 |
Well, those kinds of higher frame rates still pretty much belong to the big guns. The Phantom Flex will give you 2,000 frames a second at ultra HD or 1,000 fps at 4K. 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. |

VR and the importance of tracking
|
|
I would like to begin this article by clarifying what we at Shotoku mean when we talk about VR in live production. It’s not the production of immersive, 360 content where you need to wear a headset; we are talking about virtual studio (VS) and augmented reality (AR) work, such as placing graphics into a green screen environment or physical set. The technology used for this work is entirely different, though equally specialist – therefore it is important to understand the challenges of this kind of production in order to make informed kit choices. |

Tried and tested: DPA d:vice
|
|
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
|
 |
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.

Grand slam IPTV and digital signage platform
|
 |
Kauffman Stadium in Kansas City, Missouri, is home to major league baseball’s Kansas City Royals. Built in 1973, “The K” has a proud baseball legacy, and goes down in history for winning two World Series championship titles; one in 1985 and another in 2015 — exactly 20 years apart. The most recent win brought a resurgence of baseball fever to the stadium, hosting more than 2.7 million fans during its 2015 winning season. |

A new AEON in Wireless 4k
|
 |
Whatever production companies are doing right here, right now, today, with wireless HD production tools, they want to do right here, right now, today with 4K UHD.
That’s great, but common wisdom would share a host of challenges around 4k UHD, not least, the fact that 4K UHD requires 8x the processing power to transmit, then demands additional horsepower (and bandwidth) to accommodate the data and controls, wireless or otherwise, and of course, when you ramp up processing power, you ramp up heat generation, which needs to be efficiently evacuated. |
