The J-Tech Digital ProAV HDMI Extender/H.264 Encoder and Decoder features the most innovative technology and easy-to-use design. It is an ideal solution for different applications in different environments including home theater, church projection systems, bar screens, advertising screens, broadcasting stations, and public theaters etc. This model features three working modes. These three modes include a point-to-point, point-to-many & many-to-many configuration. Using the point-to-point mode, an HDMI signal can be extended up to 120m (394ft) over a single Cat5E/6 cable. With a Bi-Directional RS-232 passthrough, users can control RS-232 enabled devices, such as rotatable cameras, from a PC connected to their Transmitter. This extender encodes and decodes HDMI signals using H.264 compression, which significantly reduces the bandwidth usage while maintaining high video quality. These H.264 extenders can be used on your home network as long as your network router supports IGMP functionality.
