H-HDSDI-RF Wireless Video Portable Transmitter and Receiver
The H-HDSDI-RF is a wireless digital video transmission system. The unit supports input of High Definition video and audio and transmits the signal up to 2 miles. Supported inputs are HD-SDI, SD-SDI, DVB-ASI, A/V, and S-Video. The H-HDSDI-RF is based on COFDM technology and incorporates MPEG-2 or MPEG-4/H.264 based video encoding. The transmitter and receiver have built in systems to compensate for high speed movement. Real time Synchronous transmission of broadband date is possible at speeds of up to 100 mph. The H-HDSDI-RF system is ideal for high quality long distance wireless transmission of multimedia broadband information. This is useful for countless applications such as event media broadcast, police services, military command, and government monitoring.
