JVC presented at NAB 2007 a camera system that introduces, for the first time, HD capture and microwave transmission capacity, in one solution affordable to the ENG/VET segment. The ProHD Libre system offers native HD 60P capture, recording and streaming via a Compact transmitter attached to the camera, developed for JVC by Broadcast Microwave Services, Inc. (BMS). A complete system composed of camera, lenses, microwave transmitter and Receiver can be assembled for less than $30,000. Systems previous with this capacity had a cost not less than US$100,000.
The teams of electronic news collection -ENG- now have the freedom to cover live news from locations than before were out of reach due to typical limitations of wired. A team in the coverage of an exhibition of gardening, for example, can now do remote from places that have colorful images in HD, different from those close to the mobile. While the system is ideal for collection Electronic news, ProHD Free is also useful in other demanding HD VET applications, including sporting events live.
The ProHD Libre system has a JVC ProHD 200 series camera and with a super encoder Built-in that generates a high-quality MPEG-2 stream. The BMS Mini-Coder High Definition Transmitter Attached to Camera accepts compressed camera signal to 20Mbps via a IEEE 1394 connection and modulates it to 64-QAM, then transmits COFDM with a bandwidth of 8MHz on the 2GHz channel. All the Transmitter is the size of a small external battery and uses the same mount hardware. The Complete Wireless Package offers excellent weight distribution for both use and shoulder as for a hand operation. In a typical configuration ENG, the BMS receiver would feed the ASI encoded signal directly to the microwave of the mobile to send it to the station.
The GY-HD200U and GY-HD250 are
the only HD camcorders currently capable of delivering a
60p transport encoded stream, broadcast quality and
1280x720 frame over an IEEE 1394 connection at a rate of
bits less than 21Mbps.
Besides, the BMS HD Mini-coder ProHD set, which includes both
the transmitter as the receiver, is currently available to
through both BMS and JVC.
