OMVC Publishes Use Cases to Demonstrate Broadcaster Opportunities with Non-Real-Time Content

The Open Mobile Video Coalition (OMVC) today released a new report showing broadcasters how to take Mobile TV to an entirely new level of functionality through transmission of non-real-time content. A standard for delivery of non-real-time (NRT) content, recently finalized by the Advanced Television Systems Committee (ATSC), broadens the scope of Mobile TV by allowing viewers to pre-load favorite shows into the memory of a mobile device for playback later, among other uses. The OMVC has outlined these uses in a new document available at

“This is a natural evolution of the Mobile TV standard,” explained Sterling Davis, chairman of the OMVC’s Technical Advisory Group (OTAG). “Storing programs in memory, clipcasting, digital signage, video-on-demand and micro-websites are ways for the broadcast industry to improve the array of services provided to users of Mobile TV. These are examples of Mobile TV functionality that we have outlined in the use case document,” Davis added.

Clipcasting Pushes Favorite Content to You

Clipcasting would consist of short form video and audio clips, similar to podcasts, that are broadcast periodically by the broadcaster and captured in the consumer’s device. The viewer would select from clipcast services in a preference menu and be alerted when new content is available. The clips are tagged with title and metadata information. The Mobile TV standard supports the ability to do both subscription-based and advertiser-supported clipcasting, with content automatically refreshed and deleted if not played in a timely manner or when a newer version has been captured. Viewer measurement and ad targeting are also possible.

Popular clipcasting might include short segments about news, weather, radar, sports, sports scores, financial markets updates, school closings, and traffic information.

Broadcaster-delivered Video-On-Demand, Micro-websites, and Digital Signage

Video-On-Demand (VOD) from TV broadcasters would allow the user to choose content that will be transmitted to their Mobile TV device and stored on that device for later viewing (much the same as is done today with living room viewing and on-demand services.) VOD content might include short-form videos, sports or news programs, and standard length TV shows and movies. Other content might include articles, electronic books, and even video games.

Mobile TV can also deliver data to populate micro-website pages, viewable on the portable device. Information can be broadcast to populate a station’s microsite without having to rely on traditional Internet connectivity.

Digital signage is another capability of Mobile TV, and is already being demonstrated by some broadcasters. Digital signs in public transportation can offer local news, relevant advertising, weather (including radar images), and other information delivered by local TV stations to buses, cabs, trains, and stations. Mobile TV has other applications and could even be utilized as a delivery mechanism for device software updates or to manage centralized utility or local government needs by remote transmission.

Mobile TV As Emergency Beacon

ATSC is now in the latter stages of standardizing how Mobile TV can be utilized for a Mobile Emergency Alert System, delivering headline overlays as warnings, rich media transmissions such as video or weather updates, and specific instructions during weather emergencies or other homeland security situations. Both the real-time and non-real-time capability of the Mobile TV standard make it an ideal adjunct to existing emergency alert mechanisms used by TV broadcasters and mobile network operators. Mobile TV could display safe evacuation routes during floods, chemical spills, and bomb threats and provide a direct link to viewers by public safety officials.

Mobile TV played a key role in the safety of millions of people during last year’s Japan earthquakes, with virtually every cell phone in Japan serving as a Mobile TV warning device seconds before the earthquake reached heavily populated areas.

The cloud. Like a comic book superhero, there seems to be no problem it can’t fix or cost it can’t slash. Yet making the transition is not always easy and production environments are still largely on premise. Taking some practical and sensible steps to reduce risk can also help provide a basis for a successful cloud transition. A plethora of surveys from the likes of IDG and Gartner show that more than 70 percent of enterprises have deployed at least one or more cloud application or workload. Yet a closer inspection at the data reveals less than half of these cloud projects involve production...
Countless business models have spawned from the IaaS industry – resell Web hosting, blogs, public cloud, and on and on.

In his general session at 17th Cloud Expo, Harold Hannon, Sr. Software Architect at SoftLayer, an IBM Company, broke down what we have to work with, discussed the benefits and pitfalls and how we can best use them to design hosted applications.
Discussions of cloud computing have evolved in recent years from a focus on specific types of cloud, to a world of hybrid cloud, and to a world dominated by the APIs that make today's multi-cloud environments and hybrid clouds possible. In this Power Panel at 17th Cloud Expo, moderated by Conference Chair Roger Strukhoff, panelists addressed the importance of customers being able to use the specific technologies they need, through environments and ecosystems that expose their APIs to make true change and transformation possible.
Microservices are a very exciting architectural approach that many organizations are looking to as a way to accelerate innovation. Microservices promise to allow teams to move away from monolithic "ball of mud" systems, but the reality is that, in the vast majority of organizations, different projects and technologies will continue to be developed at different speeds. How to handle the dependencies between these disparate systems with different iteration cycles? Consider the "canoncial problem" in this scenario: microservice A (releases daily) depends on a couple of additions to backend B (re...
Container technology is shaping the future of DevOps and it’s also changing the way organizations think about application development. With the rise of mobile applications in the enterprise, businesses are abandoning year-long development cycles and embracing technologies that enable rapid development and continuous deployment of apps. In his session at DevOps Summit, Kurt Collins, Developer Evangelist at, examined how Docker has evolved into a highly effective tool for application delivery by allowing increasingly popular Mobile Backend-as-a-Service (mBaaS) platforms to quickly crea...
Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.
We all know that data growth is exploding and storage budgets are shrinking. Instead of showing you charts on about how much data there is, in his General Session at 17th Cloud Expo, Scott Cleland, Senior Director of Product Marketing at HGST, showed how to capture all of your data in one place. After you have your data under control, you can then analyze it in one place, saving time and resources.
The Internet of Things is clearly many things: data collection and analytics, wearables, Smart Grids and Smart Cities, the Industrial Internet, and more.
