ZT4505 UHD Zapper Terrestrial Set-Top

DVB-T2, HEVC, Ultra-HD Set-Top with 802.11ac Wi-Fi


The ZT4505 is a premium single-tuner broadcast terrestrial set-top box for market-leading operators and deployments. The zapper-style product is expected to compliment a PVR/home media server deployments and also to act as a whole-home client to these devices. However, they will also act as a stand-alone device for more cost-sensitive Ultra-High Definition (UHD) markets.

High Performance

The ZT4505 complements a media server and fills in all the customer’s next-generation UHD TV needs. A high-end, 12000-DMIPS processor, OpenGL 3.1 and DDR4 memory give the platform power into the future and allows the same premium UHD experience on multiple screens in the home.

High Quality

High Efficiency Video Coding (HEVC or H.265) is the next-generation of video codec, offering up to 50% bandwidth savings on the H.264 standard. HEVC can be used by operators to deliver a superior quality-of-experience within the same bandwidth or to increase their existing capacity by re-encoding existing assets.

UHD (or 4K) gives four times the resolution of full HD and improves colour reproduction for picture even closer to reality, all at the frame rates that allow fast-moving action with reduced blurring.

High Connectivity

The ZT4505 is a highly-connected unit with integrated IEEE 802.11ac dual-band wireless and gigabit Ethernet. This allows its use as a whole home client or as a client to a high-bandwidth broadband network. Network connection allows its use as a premium OTT device or even to implement network PVR in suitable deployments. Finally, USB 3.0 allows the connection of external peripherals and Bluetooth Low Energy allows an optional advanced remote control unit and features such as voice search to be supported.
