WAYNE, NJ (April 13, 2015)– JVC ProfessionalVideo, a division of JVCKENWOOD USA Corporation, today announced firmware upgrades that include adaptive bit rate technology for more reliable streaming, support for Real Time Messaging Protocol (RTMP), which allows a direct connection to a number of content distribution networks (CDNs) for live streaming, and a high quality 12 Mbps mode. The new features included in Version 4.0 for the GY-HM650 and Version 2.0 for GY-HM850 and GY-HM890 ProHDstreaming camcorders will be demonstrated at the 2015 NAB Show (Booth C4314), which runs April 13-16 in Las Vegas, Nev.
As proven by stations across the country, JVC cameras are a very reliable way to produce live HD reports on location when paired with a 4G LTE modem or hotspot. However, the Internet is often accessed through shared networks, which can be unpredictable. Adaptive bit rate streaming technology dynamically adjusts the quality of a video stream based on available bandwidth. The new feature is designed to maintain a live video feed from the field at reduced data rate and optimize quality based on available bandwidth.
“For many of our news customers who rely on ProHD cameras to deliver news reports from the field, live signals are essential for broadcast,” explained Edgar Shane, general manager of engineering, JVC Professional Video. “When there are changes in bandwidth due to increased Web activity or fluctuating signal strength, adaptive bit rate technology can automatically adjust the quality of the video to maximize the available bandwidth. Meanwhile, our cameras can continue to record footage to SDHC or SXHC cards in full resolution for archive.”
The GY-HM650, GY-HM850, and GY-HM890 already feature JVC’s Advanced Streaming Technology (AST) with support for secure FTP and a number of other protocols. RTMP support allows easy CDN connectivity. JVC recently announced a partnership with Ustream, the world’s live video platform leader, which allows easy input and storage of up to four Ustream credentials in JVC cameras. As a result, a live webcast can be initiated with by pressing a single button on the camera.
“The support of RTMP protocol is a significant upgrade for our ProHD cameras, because it allows our customers to connect directly to Ustream and other content distribution networks without a computer or video infrastructure,” explained Dave Walton, assistant vice president, marketing communications.
For streaming within closed networks, a 12 Mbps mode provides near-contribution quality images. The mode is ideal when multiple cameras are streamed to a switcher in a live broadcast environment, such as a sporting event. When combined with JVC's private wireless network system, the result is a highly reliable broadcast quality wireless production system.
JVC is also announcing that its BR-800 ProHD Broadcaster serverpowered by Zixi has been upgraded to provide multi-view status monitoring. Multiple live streams can now be viewed on a single monitor screen with drag-and-drop output switching.
Support for RTMP protocol and adaptive bit rate technology is included in the new GY-LS300 and GY-HM200 4KCAM camcorders, which will also be showcased at NAB. Version 4.0 and Version 2.0 upgrades are free to all current GY-HM650 and GY-HM850/80 owners, respectively, and will be available in June via a firmware update available through the JVC Web site.
