The HHD264 family of economical HDMI over LAN senders and receivers from Hall Research are designed to provide unparalleled power and ease of distributing one or more HDMI sources to multiple displays on any LAN. Up to 64 independent senders can be simultaneously connected to the network and up to 256 receivers can be accommodated. Full-HD (1080p/60) video is transmitted with user-definable bit rate.
For a perfect image Full-HD uses 15 Mbps where as HD (1080i or 720p) uses 12 Mbps. However if the content is mostly static (such as slide shows), users can encode with lower data rates to save bandwidth and still have a perfect image.
HDMI video and audio are extended along with bi-directional RS-232 data. Video routing from the senders to the receivers can be pre-assigned (using multi-cast group dip switch), but the system can also behave as a Dynamic Virtual Matrix Switch. For fixed signal routing from senders to receivers the dip switches can be set to route senders to any one or group of receivers. However, users can also switch the source shown on any receiver on the fly (dynamically). This is done by going into each receiver's IP address and accessing the WebGUI, or by using Hall Research's free Dynamic Virtual Matrix Windows software.
Both PoE and standard (non-PoE) senders and receivers are offered. The PoE versions do not come with power supply as they get their power from a PoE network switch.
