Lawo's V__remote 4 is designed to provide a one-box solution for all the requirements of video and audio signal transport and processing in WAN-based remote productions. It includes everything from Video-over-IP coding to various monitoring and processing tools. All designed for one purpose: to provide a tool that increases the flexibility of any broadcast application, while saving valuable rack-space, set-up time and production costs. With its virtual cabling capability, V__remote 4 leverages IP infrastructure advantages and cost savings to provide an unparalleled degree of flexibility and scalability.
In remote live production, IP is becoming a fundamental requirement, and getting reliable, low latency and high-quality video from venues back to studios at reasonable cost is an absolute necessity. The Lawo V__remote 4 achieves this by combining a bi-directional, four-channel Video-over-IP interface, four local SDI inputs and outputs, and all the processing tools usually needed when contributing video and audio via WAN or LAN to a broadcast production, into a compact 1RU devices.
V__remote 4 provides four 3G / HD/ SD SDI inputs and four 3G / HD / SD SDI outputs for interfacing to external video equipment, and converts these signals into IP streams (and vice-versa). These streams can be transported via standard Layer 3 IP LANs or WANs. V__remote 4 provides parallel encoding in multiple streaming formats, making the same signal available to different applications – e.g. RAW for local production, JPEG2000 for remote sites, MJPEG and H.264 for monitoring applications, and H.264 for internet distribution. The IP-based approach allows easy signal routing via Lawo’s VSM control and monitoring system or other external master control systems. No rewiring is needed as long as all devices are connected to the network. Since the device is based on real network technology with multicast capability, it allows easy transmission of signals to multiple outputs within the network.
The V__remote4’s coding engines are designed to meet the highest demands for video quality and signal transport reliability. The extremely robust J2K codec (with a special protection algorithm for signal transport even on unreliable WAN connections) and ST2022-7 port redundancy ensure signal availability and quality. Lawo’s EPS technology for enhanced protection switching goes even further, enabling system designs with true hardware and network redundancy. Format and quality of the IP video streams can be configured individually to provide the optimum balance of picture quality, latency and bandwidth. Its 6 Ethernet ports are connected to an internal switch allowing “tunneling” of IP traffic such as camera control, RAVENNA streams or even office and Internet IP, through the 10GBit interface.
