JVC Professional Products Company unveiled its new KA-AS790G ASI module, which facilitates a camera’s built-in encoder and provides a compressed MPEG-2 output that is ideal for microwave transmission and long cable runs for outside broadcast (OB) vans, the company says in a written statement.

The module attaches to the back of the GY-HM790U or new GY-HM750U camera without external wiring or adapters, outputs the live signal from the camera, even while recording, via a standard BNC connector, JVC says.

Both high-definition (HD) video and audio are compressed using the camera’s built-in encoder (running at either 19.7 Mbps or 35 Mbps), which creates an MPEG-2 signal and then provides lossless transcoding to DVB-ASI, JVC says. The module. 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,” said Craig Yanagi, JVC Professional Products Company’s national marketing and brand manager. It “eliminates the need for an external encoder on location, which simplifies the transmission process and helps reduce clutter,” he said, adding, “It’s a great tool for broadcasters that need a reliable way to uplink video from the field.”

The KA-AS790G module will be available in February 2011 and be demonstrated at the 2011 NAB Show, which runs April 11 through 14 at the Las Vegas Convention Center in Las Vegas.
