JVC continues to push the envelope of embedded connection products with the new GY-HC900’s complete IP workflow includes streaming performance up to 20 Mbps and built-in Wi-Fi (2.4GHz/5GHz) with dual external antennas. The camera also features Zixi error correction with automatic repeat request (ARQ) and SMPTE 2022 forward error correction for reliable transmission. Beyond ENG, the GY-HC900 could be an ideal choice for high-end EFP and studio fibre applications. It works with the FS-900 camera module, which attaches to the camera via a 68-pin interface, and feeds 3G-SDI signals, control, audio, sync, and intercom to a base station via fibre. An integrated 3G-SDI pool feed input allows the GY-HC900 operator to capture video and stream it live simultaneously. Camera functions can also be controlled via web browser or the JVC RM-LP100 remote camera control. The camera also boasts an IPX2 water-resistant rating for operation in challenging conditions. Other features include a genlock input, time code in/out, dual 3G-SDI outputs and an HDMI output, three XLR audio inputs, Ethernet and USB ports, wireless audio module slot, and an additional slot for future expansion. Equipped with an industry standard B4 lens mount and four-position optical filter. The 2/3in CMOS sensors, each with 1920x1080 pixels, combine with an f/1.4 prism to produce full HD images. The camera also offers an HDR mode for creative flexibility, as well as up to 120fps 1080p slow-motion recording. With dual memory card slots for SDHC/SDXC media, the GY-HC900 offers redundant, relay and backup recording modes. It also records proxy resolution video clips for offline editing or online posts. The camera includes a 3.26in OLED colour viewfinder, as well as a 3.5in LCD panel for menu navigation.
American company Niagara is known for the quality of its encoding but has now entered the on-camera streaming ‘straight to air’ world with its GoStream range. Niagara is already known for its high-end IP encoding for closed networks, but the company has seen the evolution of on- camera systems and brought its encoding knowledge to bear on the market. GoStream boxes can stream HD now and will soon be able to stream 4K. Niagara’s big claim to fame is the real-time aspect, which you would expect from an encoding specialist. The system comes with the Niagara SCX Encoder Remote Management software that includes enhanced audio features for adaptive and non-adaptive encoders. Additional options include an optional audio input card. Niagara products support the most popular content delivery networks (CDN) including Akamai, DaCast, Ustream and YouTube. GoStream is also compatible with streaming media servers such as Adobe Media Server, Microsoft IIS, the Wowza Streaming Engine and PC players such as VLC and IP Set Top Boxes. GoStream uses standard Internet to get to a user or a full platform; it’s interestingly also a recorder at a data rate good enough to broadcast from. The system will pick up Internet wherever it is but also has the ability to jump on a 4G data connection. Although GoStream is Niagara’s new on-camera system, companies like the BBC have many of their higher end rack-mounted IP streaming boxes. Corporations are also looking to these solutions for huge IP encoding projects which allow any person in a company to go live on-air without installing heavy fibre or typical broadcast infrastructures. So think ‘super conferencing’, but actually much more than that.
What do you really need from a generation- two on-camera wireless device? It would help if it was smaller, lighter and tougher. Well, what do you know, the new Paralinx Tomahawk2 is all those things as well as remaining the same long-range HD video system that offers you real-time wireless HD transmission for your television, film, broadcast, industrial and UAV/UAS application. It’s a video receiver and transmitter combo with a wide input voltage range of 6-28V, a dual input transmitter (HD-SDI and HDMI) and is lighter and 60% smaller than the first-generation Tomahawk1 so has a great small form factor. The Tomahawk2 is also compatible with the Teradek Bolt 2000, Sidekick 1 and Paralinx Tomahawk1. Tomahawk2 claims a range of up to 2000 feet (609m) and maintains a less than one millisecond latency glass-to-glass. The Tomahawk2 system features both 3G-SDI input (with loop-out) and HDMI input on the transmitter and a 3G-SDI output on the receiver. It transmits full-HD video (up to 1080p/60 4:2:2) and is capable of sending video to up to four receivers simultaneously. The transmitter weighs approximately 208g and the receiver weighs only 252g (both weights are without antennae). The Paralinx Tomahawk2 system is available for one transmitter and receiver pair. Battery plates, antennae, mounting brackets, power cables and custom cases are all available as accessories to help customise your set-up. Other features include 128-bit AES Encryption to make sure you get the ultimate secure transmission. Operation on 5GHz frequency band is guaranteed and Paralink is committed to conforming to major technical and environmental standards.
