The Dynamic Duo: SDR and HDR – Compatible Workflows for Live Production
Customer feedback on 4K UHD tells us that more pixels alone will not satisfy market expectations for a next-generation broadcasting format. Having better pixels with a higher dynamic range is therefore a hot topic of discussion.

A UHD 2/3-inch CMOS imager with Dynamic Pixel Management - an Enabler for New Format Flexibility
The broadcast market currently faces changes which are very challenging for imaging solutions; the change from HD to UHD, and the introduction of HDR. In phases of change, more flexible solutions are needed. The Dynamic Pixel Management (DPM) technology already available in some FT-CCDs offered a unique solution for lossless switching between 4:3/16:9 aspect ratios, as well as between all the different HD formats, including 2.37:1 widescreen.
Changes in Technology and Viewership – Grass Valley Is Ready
Depending on where a media organization or broadcaster is geographically located, they are dealing with a myriad of technological and viewership changes, from HD to 4K, SDR to HDR, even SD to HD, with the television set being relegated to a piece of furniture with people watching "TV" on a variety of devices (including traditional TVs) based on their own schedules.
We asked Marco Lopez to address the changing television and media business as the industry approaches NAB 2017.
The Broadcast Data Center: Changing the Way We Think About Broadcast.
Looking at the success stories found in new media companies that are leveraging IT solutions to achieve new levels of agility and capturing increasing market share, you find that the agility they achieved was a direct result of the Modern Data Center technologies they were deploying. They are using distributed, scalable networks and virtualized computation to achieve this level of agility which gives them a competitive edge versus the traditional SDI based broadcasters of today. The Broadcast Data Center is a concept developed to characterize new, innovative solutions evolving in the broadcast market.
Using IP to Solve the Multiformat (HD, 4K & HFR) Truck Challenge
Today's live production space is in a state of change, again. The progression of UHD 4K deployments marches on in many geographies. Other technological changes including HDR and WCG which were seeing proof of concepts in the past year are now seeing production deployment. At Grass Valley we have been working hard behind the scenes to support those tests and bring to market products that will add value to these technologies in real world production.
Evolution of 10 GigE and Beyond
The maturity and affordability of 10 Gigabit per second Ethernet has enabled the broadcast industry to move towards an IP technology platform. The volume of conversation about IP and 10 GigE will reach a new high this year at NAB 2017.
The Power of Choice Meeting the Challenges of 4K UHD Acquisition
Image acquisition for live broadcast applications faces many challenges in a multiformat landscape. The increase in spatial resolution required by 4K UHD, in combination with the additional requirements of UHD standards, including a potential increase in frame rate and high dynamic range with good sensitivity and S/N ratio will require some compromises and design decisions on the part of manufacturers, and camera selection on the part of camera users.
Raising the Drawbridge
Part two of two. To continue Scott's analogy from the last post, broadcast facilities may have once have been isolated islands, but today they are solidly linked by the bridges of technology. Let's look at why this connectivity is an advantage, the risks it brings, and what we can do to minimize them to pull up the drawbridge! We will look at three points of view: the broadcaster's, the consumer's, and the hacker's.
How Secure is Your Broadcast?
Part one of two. On November 22nd 1987, viewers in Chicago watching WGN-TV's nine o'clock news were interrupted by a strange character appearing on screen. The attacker, wearing a Max Headroom mask, had hijacked the studio link. The event lasted for less than a minute, and was the first widely publicized hack of a broadcast TV station. The hacker has never been identified.
The Content Revolution –
What will the broadcast experience look like in five, ten or twenty years?
It took about 26 years to make the transition from broadcasting black and white to color TV (although color TV would not become popular for almost 10 years as the price of televisions and producing in color became more affordable). Then another 44 years to move from standard to high definition (HD). Then only 18 years to see 4K, and fast forward four years to 8K or 16K or whatever else is on the horizon. And I'm not even including markers for HFR, HDR, increased metadata…
