NetFront™ Browser NX 3.0 DTV Profile

An advanced, high performance WebKit-based HTML5 Browser for Digital Television and capable of delivering advanced UX on lower power STB/DTV platforms

NetFront™ Browser NX DTV Profile is an advanced WebKit-based HTML5 browser that features efficient memory usage, high stability, high portability and wide support for DTV standards or specifications including HbbTV 1.5, HbbTV 2.0, UK Freeview Play, YouTube on TV and CE-HTML. NetFront Browser NX DTV Profile is an ideal solution for DTVs, set-top boxes, game consoles, Blu-ray Disc™ players and automotive infotainment systems.

NetFront Browser NX DTV Profile was designed and optimized to address the real world shortcomings that affect WebKit-based browsers, including poor performance in resource constrained STB platforms. Typically, in-house solutions show instability in embedded environments and have platform-dependent implementation/porting layers and lack DTV-specific extensions, leading to a large engineering investment by set-top box manufacturers and middleware providers to develop and maintain. NetFront Browser NX DTV Profile is provided as an embedded SDK pre-configured for the target platform and incorporates ACCESS technologies deployed in over 1.5 billion units worldwide. These include enhanced stability in low memory situations enabling devices to perform for longer without needing to be rebooted. Also, flexible porting APIs enable cross platform support for multiple SoC vendors whilst still allowing access to hardware accelerated functions. ACCESS SDKs can support standardized APIs such as OpenGL-ES for higher end platforms and software engines such as Cairo for lower power platforms without hardware graphics processing units (GPUs).

Advanced HTML5 and DTV Standards Support

NetFront Browser NX DTV Profile delivers high levels of HTML5 and CSS3 support as well as wide support for DTV specifications such as HbbTV 1.5, HbbTV 2.0, Freeview Play, YouTube and CE-HTML, all provided as an embedded software development kit (SDK). Platform agnostic APIs and DVB middleware-independent DTV extensions provide high portability ensuring improved time-to-market for DTV and STB manufacturers. Browser application APIs enable free and flexible UI customization to ensure that the operator receives the branded solution they demand. NetFront Browser NX DTV Profile is offered as a configurable SDK based solution that includes software components, world-class engineering support, professional services, documentation, regular software updates and product roadmaps.
