The AVerCaster HD Duet streams live HD video from cameras and TV set-top boxes to numerous users in a LAN environment. Compared to conventional coaxial cable or aerial based TV/video distribution systems, it provides a cost-effective solution for small and medium-sized enterprises. Featuring multicasting over an IP network, the AVerCaster HD Duet encodes and simultaneously distributes high-definition video content from devices with an HDMI or component output (Blu-Ray players, TV set-top boxes and camcorders) to an unlimited number of users over the same network. Simultaneous streaming includes the ability to stream up to two HD video broadcasts. This single box streams HD contents via standard protocols. Thus, live video information or entertainment broadcasts can be delivered to a wide range of client devices including computers, IP-STB, kiosks, digital signage and hospital infotainment terminals. It can be easily deployed into existing network environments and common systems without extra cost or effort. Besides, the AVerCaster HD Duet adopts H.264 compression, which can prevent the dilemma of high video quality versus efficient bandwidth usage. The AVerCaster HD Duet is equipped with an intuitive web-based content control interface for easy configuration. In addition, any PC under the same domain can access the controls.
