Broadcast Sports Inc (BSI) is to unveil its new Pan Tilt Roll Zoom remote-controlled wireless camera system at IBC (stand 5.B20). The PTRZ is a waterproof 1080i HD camera designed for rental and for mounting on sailing vessels. The company says it is also adapting the camera for land-based applications that would benefit from its robust functionality. It has a 10x optical zoom lens with dimensions 210mm x 165mm, weighing 2kg. All aspects of the camera are adjustable remotely via the UHF channel to a built-in data receiver: most importantly the pan tilt roll and zoom functions, also the red/blue gain, iris, focus, shutter speed, saturation, master gain and master pedestal. The operator can also change the RF parameters of transmission frequency and modulation scheme, and switch from standby to operational mode. It uses COFDM wireless encoding at H.264 MPEG-4 and MPEG 1 Layer II with QPSK and 16QAM modulation, and operates on frequencies from 1.4 – 1.5GHz or 2.0 – 2.5GHz. BSI can supply models for other frequencies. BSI is also showing a new 3D wireless camera package for live broadcast, featuring return vision, camera control and remote convergence. It will be demonstrated on an integrated Panasonic 3D camera, with low delay encoding, and full camera control. BSI uses its own dual-stream mini encoder/transmitter, a tiny device little larger than a cell phone, to carry the two signals simultaneously. This ensures synchronous signals from the two cameras used to capture the pictures from the left and right lenses. BSI has added its own in house-developed UHF camera control, which allows the operator to adjust the parameters of the camera and control convergence between the left and right eyes using the manufacturer’s control panels. This means that the images from the 3D rig can be matched to the images from other cameras on the production. www.broadcastsportsinc.com By Adrian Pennington
