We have been researching a wireless camera system called "Millimeter-wave Mobile Camera", whose performance and functionality match those of cable-connected High Definition Television (HDTV) cameras. HDTV pictures transmission with high-capacity and low delay for main link and HDTV camera control signals transmission with high link reliability for return link are required for the wireless camera. To fulfill these requirements, millimeter-wave (42/55-GHz) band and Multiple-Input Multiple-Output (MIMO) multiplexing technology enable main link to wirelessly transmit compressed HDTV video at rates of up to 160 [Mbps] with a latency of less than one picture frame. In addition, the millimeter-wave band and Space-Time Block Coding (STBC) technique are also used for return link to realize important camera functions such as highly precise HDTV camera control. This paper describes the feature of the wireless camera system and MIMO technologies for main link and return link, and operation example of the wireless camera in the 61st NHK Red and White Year-End Song Festival.
