Just what the world needs: another consortium promoting a wireless technology for the transmission of HD content in the home. The latest is the Wireless Home Digital Interface (WHDI), launched today by Sony, Samsung, Hitachi, Motorola and Sharp. WHDI's technology comes from Israeli company Amimon. It uses the 5GHz band to transmit uncompressed 1080p video, audio and control signals around the home from multiple sources to multiple receivers. All this data is beamed at up to 3Gb/s.
Amimon claimed WHDI's range is 30.5m. It can go through walls and has a latency of less than a millisecond. The technology was developed specifically for video, Amimon said. It "takes the uncompressed HD video stream and breaks it into elements of importance. The various elements are then mapped onto the wireless channel in a way that give elements with more visual importance a greater share of the channel resources".
