ALEXANDRIA, VA. Two decades ago, it was a struggle to get full-resolution standard-definition video to play smoothly on a computer. Today, a well-equipped modern PC bought at Costco can handle resolutions up to 4K without glitches, yielding inexpensive processing power that simply needs software to do whatever video task you require.
To get some idea of why your next infrastructure upgrade might be more about software than hardware, Broadcast Engineering Extra spoke to Keith Wymbs, chief marketing officer for Elemental Technologies.
Keith has 20 years' experience in the video, IPTV and telecommunications industries. As chief marketing officer at Elemental, Keith leads the development and implementation of the company's worldwide marketing strategy and oversees its marketing functions, ranging from product management to outbound communications.
Prior to joining Elemental, Keith led the marketing team of IPTV pioneer Tut Systems (acquired by Motorola), and the business development efforts of Viagate Technologies (acquired by Tut Systems).
BE Extra: What is software defined video and why should we take note of it?
Wymbs: Though fixed-function hardware may continue to provide high performance and good picture quality for specific applications such as standard definition TV over traditional networks, long product lifecycles mean the technology has a low likelihood of keeping pace with market changes. Software running on general purpose processors can now surpass task-specific video processing equipment in terms of both picture quality and performance, while simultaneously adapting to market change.
SDV is an infrastructure-agnostic approach to implementing flexible, scalable and easily upgradable video architectures. Unlike legacy solutions, this advancement allows video providers to deploy software across an optimal combination of dedicated and virtualized resources in both private and public data centers.
Software-defined video provides a new way for media enterprises to engage customers with innovative services such as timeshift and multiscreen TV; offer viewers better video experiences; and reduce capital expenditures. Broadcasters and pay TV operators rolling out premium streaming services can strengthen their competitive position and speed time to market by deploying software-defined video processing architectures as the core of their next-generation infrastructures.
BE Extra: Now that computers can handle HD easily without pricey dedicated graphics systems, it looks like many people are jumping on the 4K bandwagon. Will software defined video always be chasing the complexity of video?
Wymbs: SDV is the only approach that can help media enterprises reduce can handle the demands of an increasing complex video landscape!
Software defined video minimizes technology risk, while maximizing innovation speed and return on investment. For example, the flexibility unique to SDV solutions is vital to the continued expansion of services like 4K and UHD services. SDV solutions used to process MPEG-2 video can offer a more seamless migration path to H.264 and high-efficiency video coding (HEVC/H.265) than dedicated hardware equipment.
Proven in major global live production events, including the Sochi Winter Olympics and 2014 World Cup, software-defined solutions can offer full frame rate 4K/HEVC video processing support.
BE Extra: What are a couple of powerful things that SDV can do today to make the lives of broadcasters easier?
Wymbs: The software-based approach to video processing enables media enterprises to lead and manage the transition to new video codecs such as high-efficiency video coding (HEVC/H.265), advanced audio codecs, advanced color spaces, increased color bit-depth, object-oriented audio specifications, forensic watermarking and new display formats such as 4K Ultra HD.
Video infrastructure complexities and expense are daunting for broadcasters deploying new multiscreen TV and OTT services. SDV mitigates that by unifying head-ends and workflows, while assuring broadcast-grade performance and reliability.
BE Extra: What about the future? As regulations and standards change, how easy is it to update an SDV product to maintain its function?
Computer graphics cards now have considerable processing power that can be harnessed for SDV applications.
Wymbs: A software-defined approach frees video providers from the constraints of dedicated equipment by allowing for the best architecture and processor combination to be used for a particular application, even if that application changes over time. Support for new services and video formats can be integrated seamlessly through simple software upgrades and API integration of third-party software, enabling video providers to immediately respond to changes in consumer demand.
Broadcasters and pay TV operators who choose software-defined video solutions don't have to wait for new custom video chips to be released to market, they can continually update and enhance their platform in line with increased consumer demand and technology advancements to create new revenue generating video services.
BE Extra: In the new world of video, content is watched on a variety of devices. How does SDV fit into that picture?
Wymbs: With SDV, live-to-VOD features such as nPVR and catch-up TV can be integrated at any time, allowing for even more flexibility and scalability. In dedicated hardware environments, trying to integrate third-party ad messaging or forensic watermarking capabilities means enabling communication with legacy video processing equipment. With its ability to support third-party integrations, a software platform allows all sorts of advanced features and capabilities to be fully integrated into a single unified system.
