  RF-503RX »

The HDTV Digital Wireless Camera System is the ultimate system combining various technologies Ikegami has developed and promoted for years such as high definition television camera technology, image compression and microwave transmission. By joint development with NHK and NHK Technical Services, Inc., it has become the first practical high definition digital wireless system using microwave band.

The system consists of HDTV transmission, HDTV receiving and back channel parts. The HDTV transmission part combines the HDL-0101 camera and the PP-53 RF unit. The back channel part includes the back channel transmitter “DMC-2511�Eand the receiver module built-in the camera. The HDTV receiving part is the PF-503 64QAM-OFDM FPU.

The system allows for three different ways for operation:

1. Without using the RF parts, the MPEG2 encoder built-in camera can directly connect to a network by ATM line via copper. In this way, the camera can transmit HDTV data directly from the site.

2. The camera and the docked RF unit can work together as a portable wireless camera and further the back channel part can be included for a handy wireless camera with communication system. The back channel part provides intercom communication, tally and camera control, which makes sports program productions easy and allows for the operating panel to be in the mobile production van.

3. The RF unit can be separated from the camera and connected to it by cable. Operation of the RF unit with battery and an electromagnetic horn antenna allows for long distance transmission.

The system offers distinctive merits. Using as an MPEG2 camera allows for direct transmission or direct feed where a copper cable is available. This will reduce the requirement for conventional short-distance FPU transmissions and tape delivery. When the RF unit is docked to the camera, the built-in OFDM system will maintain robust operation even in a multi-path environment, so the system can be used in an urban area or with a crowd. In a sports event, this allows for the camera to access areas where cable laying is not possible and gives program production unique capability.
