JVC Professional Products Company is demonstrating its new KA-AS790G ASI module at NAB. It provides a compressed MPEG-2 output for microwave transmission and long cable runs for OB vans with no additional encoding required. The module attaches to the back of the GY-HM790U or new GY-HM750U ProHD camera without external wiring or adapters.
Both HD video and audio are compressed using the camera’s built-in encoder (running at either 19.7 or 35 Mbps), which creates an MPEG-2 signal and then provides lossless transcoding to DVB-ASI. The module outputs the live signal from the camera, even while recording, via a standard BNC connector. When the camera automatically detects the presence of the KA-AS790G module, it switches to low-latency mode.
“The KA-AS790G is another example of how our elegant modular approach brings added versatility to our ProHD camcorders. It’s a great tool for broadcasters that need a reliable way to uplink video from the field,” says Craig Yanagi, national marketing and brand manager, JVC Professional Products Company. “It also eliminates the need for an external encoder on location, which simplifies the transmission process and helps reduce clutter.”
JVC will also be presenting the GY-HM750U ProHD compact shoulder-mount camcorder. It delivers 1920×1080 images in a small, lightweight form factor and records at selectable data rates up to 35 Mbps. The camcorder can also record HD footage in 720p, 1080p, and 1080i, as well as SD footage (480i). Stand C4314
