The Zx4430 is an Android TV compliant DVB platform which uses the latest technologies to reduce power consumption and increase processing capabilities.

High Quality Video Experience - Ultra-HD, 10-bit colour and High Dynamic Range deliver four times the resolution of full HD, improved colour reproduction and a wider luminance range for an image that’s even closer to reality, all at frame rates that allow fast-moving action with reduced blurring. The Zx4430 includes HDR<>SDR conversion for video and graphics, allowing the seamless use of legacy UIs on HDR displays, and the viewing of HDR content on conventional displays without the need for simulcasting.

Enables a wide choice of User Experience – a high-performance processor, 3D OpenGL and fast DDR4 memory give the platform the power to support a wide range of middlewares including Android TV to deliver a modern user experience.

Connectivity - the Zx4430 is a highly-connected unit with integrated IEEE 802.11ac dual band wireless and Fast Ethernet. USB 2.0 allows the connection of additional storage devices for functions such as time-shift TV. The Bluetooth Low Energy remote control option supports voice search and allows for hidden installation.
