Zenterio OS

The uniqueness of Zenterio’s Linux-based operating system has its origin in Nokia’s vision from the 1990s. Interactivity, speed and hardware independence have always been the guiding principles for developing Zenterio products.

True independence for TV operators

Zenterio’s uniform operating system makes TV operators independent in their choices of hardware, middleware and back-end solutions. This freedom of choice helps them avoid vendors dictating the rules as well as overly complicated, non-standard solutions. With Zenterio OS, operators are free to focus on service development as an independent business driver rather than staying locked in by current ecosystem limitations. Zenterio OS is built with minimal dependency on other partners. The system features an extensive framework architecture, which enables fast adaptations to market needs and introductions of new “must have” features.


World-class performance on millions of boxes

In the early phases of development in the 1990s, Nokia faced tough hardware limitations. This led to an in-depth analysis and search for the optimal architecture and programming language. Nokia chose an event-based approach and C++. At the time, this was a bold decision, years ahead of the competition. The modular capability and the strict use of limited software abstraction layers resulted in a product that has given Zenterio a strong reputation for providing a world-class software.

Performance has been at the core of each new generation of Zenterio OS, enabling the operator to make the most out of whichever hardware they deploy. Zenterio has improved the performance of legacy set-top boxes in harmonization projects and created opportunities for TV operators to offer services not previously believed to work on a particular hardware. This significantly improves revenue generation from new services as they can be offered to the entire customer base. Performance continues to be the cornerstone for development of Zenterio OS. This focus has made Zenterio OS the core of millions of stable set-top boxes in the global market.

Swap-out of existing software


Having worked on most of the deployed chipsets in the market for the last 10 years, Zenterio OS has a unique ability to replace proprietary operating systems used by other manufactures. For an operator to reap the full benefits of a harmonization of operating systems, Zenterio OS can be deployed not only on new set-top boxes, but also to the base of boxes already in use by the operator’s customers. Zenterio can, through a unique offering called “swap-out,” remotely replace proprietary operating systems that are already in use. The swap-out is a vital part of Zenterio’s total offering and highly appreciated by pay-TV operators stuck with a diversified base of propitiatory STBs in their customer base.

The legacy swap-out is a core component for most of our larger customers and often one of their key enablers for venturing into service profitability. We expect this to grow in demand as the problems caused by the current parallel proprietary systems in combination with an increased service roll-out demand become more evident for the operators.

Leveraging the service explosion

A unified software platform for an operator means a far better environment for application development. Zenterio maintains several application interface technologies, which give the operator an open choice of how to build and deliver services. In cases where limited hardware is available, native applications most often improve performance significantly. Different browsers provide different benefits and Zenterio supports several major browsers, including Opera, Web Kit and Ekioh. For third-party application developers, Zenterio offers an application interface. As part of the application interface, Zenterio also offers tools and libraries to developers. Further development of these tools, libraries and interfaces are crucial in order to provide incentives for the application development community. Today, operators who have selected Zenterio OS already benefit from the interest of major application companies that wish to offer their services to the TV screen. Zenterio believes this will be key to continuing to creating great value for both Zenterio’s customers as well as Zenterio itself, since these applications will independently add value to the offer provided by the Zenterio OS.

Embracing social TV

The introduction of social media has been a game shifter for how media is consumed online and is already changing the pathways of how users discover new content. Its rapid evolution can also serve to illustrate the ever-changing environment that today’s operators have to adapt to in order to keep their current customers in the future. Without a solution that allows for rapid service deployment and a structure to embrace the infrastructure that social media creates, TV operators will be stuck on the sidelines in tomorrow’s competitive landscape.

Zenterio OS represents the key to transforming increasing internet connectivity and rapid service evolution from a threat into an unparalleled opportunity for growing revenues and increasing customer loyalty.
