The NTVH4K is an Ultra High Definition H.264 and H.265 video and audio encoder that is capable of offering full 4K UHD video and audio encode as multicast or unicast streams. It can also encode are a variety of other resolutions including 1080P, 720P and 360P.

The encoder can be used as an Ultra High Definition (UHD) IP video encoder where video and audio sources are connected to it via a HDMI cable and the unit is connected to a network. Any PC that can reach it over the network can view the UHD Video, listen to the audio and access all of its control features via the NetworkTV Management Interface.

The NTVH4K encoder also supports 3G-SDI via bayonet connection and will encode at 1080P HD quality. The encoder also provides local output of the HDMI, 3G-SDI and audio sources.

The encoder can stream video directly onto an IP network, creating channels from the output of a wide range of sources, including satellite TV set- top boxes, cameras, digital signage systems and computers. Combining NetworkTV Encoders with the NetworkTV management system to create HLS channels can also extend video streams outside the LAN for direct delivery to mobile devices or contribute to Content Delivery Networks.

The encoder is capable of providing dual streams in different formats so for example it will provide a multicast high bit rate and an HTTP stream low bit rate. The NTVH4K encoded stream can also be recorded on the NetworkTV Management Server and published in the NetworkTV Library Archive. It will also provide the capability to add logo’s, watermarks, timestamp, as well the ability to add existing IP streams into a multi-stream mosaic layout.
