Abstract: We have developed a 42-GHz wireless HDTV camera that has bi-directional wireless transmission in the main and return links. We implemented a main link using a millimeter-wave wideband and Multiple-Input Multiple-Output (MIMO) technology with two transmit and four receive antennas to transmit high quality (data rate of 320 Mbps) and low latency (less than 1 picture frame) high definition television (HDTV) video. In addition, we also implemented a return link using a millimeter-wave wideband and a Space Time Block Coding (STBC) technique with four transmit and one receive antennas to transmit return high link reliability and low delay HDTV video. We also achieved camera functions equivalent to those of cable-connected cameras, such as precise camera control, genlock and intercom communication, using the bi-directional transmission. These performances make it possible to switch seamlessly between pictures from cable-connected cameras and this camera with the same operability as cable-connected cameras. This wireless camera has been used in several productions without any interruption while moving freely within a range of several hundred meters.
