In September, the AJA Video Systems BRIDGE LIVE v1.12 debuted. It’s a new software update for AJA’s turnkey multi-channel live video solution for remote production, contribution, collaboration, streaming, and delivery. The release features bi-directional NDI (Network Device Interface) input, output, and transcode; HLS output; video preview; and user interface updates for more intuitive configuration. The bi-directional NDI support makes it easy to encode SDI inputs for NDI output to the network and/or to receive NDI for outputting SDI. The ability to also transcode H.264/H.265 streams to NDI and/or transcode NDI inputs to H.264/H.265 enables a host of new workflow possibilities. Bringing bi-directional NDI I/O and HLS output to BRIDGE LIVE supports broader hardware and software integration

AJA Video Systems also has the first 12GSDI embedded audio-to-Dante audio bridge. Targeted at live event and Pro AV workflows, the AJA OGDANTE-12GAM is an openGear, Dante audio embedder and disembedder, with dual 12G-SDI ports, 64 channels of audio, and DashBoard control software integration. The high-density solution bridges 12G/6G/3G SDI sources with embedded audio to and from the Dante audio ecosystem. OG-DANTE12GAM features industry-wide compatibility with openGear frames, allowing for up to 640 channels of SDI/Dante audio bridging within a single 2RU frame housing ten cards.

The Altinex TP315-101 HDMI over AnyWire transmitter carries 1080P HDMI signals up to 300 meters using a simple 2-conductor cable; the transmitter can use up to four receivers connected directly through unbundled wire or in a daisy-chain pattern. There is also an IR pass-through for receiver end to transmitter end control. For transmitter output confidence monitoring, a video output is provided to support a local monitor.

Apantac has a unique KVM over IP solution for the popular openGear platform – the Apantac OG-KVM-IPTx. This KVM over IP card is compact, modular, hot-swappable, and hot pluggable. Up to twenty OG-KVM-IP-Tx boards can fit into a single 2RU frame with built-in redundant power supplies and network management. Since it is based on the openGear standard, system integrators can also mix and match different cards from multiple manufactures in a single frame.

It handles multicast encoding and decoding at origination and destination, and comes in several hardware configurations depending on the number of simultaneous streams required.

A set of audio distribution “problem solvers” from RTI consists of digital audio converters (DACs), a delay module, and an extender kit. The products are purpose-built to resolve common audio challenges. New RTI DACs include the ADA-1 Dolby Digital-toAnalog Downmixer and the VDM1x HDMI Downscaler With Downmixer. The ADA-1 decodes audio signals from sources with S/ PDIF coaxial or TOSLINK optical outputs— such as Blu-ray players and media streamers—and converts them to standard stereo output for analog sound systems. The VDM1x is well suited for multi-zone installations featuring a mix of both HD and 4K sources and displays. In addition to downscaling or upscaling for displays of different resolutions, the unit down-mixes incoming Dolby Digital to stereo PCM audio. To address lip-sync issues and the challenges of long-distance signal distribution, RTI offers the ADM-1 Audio Delay Module and AXP-1 Digital Audio Extender Kit, respectively. To compensate for delays caused by differences in the audio processing speed of output devices, the ADM-1 allows integrators to delay audio from 20ms to 340ms using a 16-way selector dial. The AXP-1 seamlessly transmits audio over distances surpassing 650 feet using a standard Cat-5e/6 cable. The unit supports coaxial and S/PDIF digital audio signals, stereo and multi-channel digital audio, two-channel PCM sources, and 5.1 compressed audio.

The SnapOne Binary 520 Series 1080p HDBaseT conference room extender and scaler can convey HDMI or VGA with stereo audio signals over distances up to 230 ft. along with bidirectional IR, RS-232 and IP over a single Cat-X cable. Priority can be given to either HDMI or VGA video input via DIP switch settings. For more installation versatility, a single 12VDC power supply can operate the transmitter and receiver units. Source equipment can be operated on the same link with system’s bi-directional IR, RS-232, and IP capability. For longer runs, the Binary 560 series carries up to 18Gbps of [email protected] 4:4:4 and bi-directional IR and RS-232 up to 330 ft. It also supports 2-channel PCM, Dolby Digital, Dolby Digital Plus, Dolby TrueHD, Dolby Atmos, DTS, DTS-HD Master Audio, and DTS-X. A front panel DIP switch provides control for different modes of operation.
