V__remote4 – The all-in-one solution for IP-based remote productions

Lawo's V__remote 4 is designed to provide a onebox-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  immediately brings IP infrastructure advantages and cost savings, providing an unparalleled degree of fl exibility and scalability.

Remote production for realizing tomorrow's visions already today.
With the performance and maturity of today’s IP network technology, video-, audio- and control-over-IP are becoming the solution of choice for many applications. In remote live production, which is increasingly regarded as the next major evolution of broadcast production, IP is becoming a fundamental requirement. Getting reliable, low latency and high-quality video from venues back to studios at reasonable cost is an absolute necessity for this.
The Lawo V__remote 4 is the ideal tool for achieving this vision of IP-based remote broadcast production today. The device combines a bi-directional, four-channel Video-over-IP interface, four local SDI inputs and outputs, along with all the processing tools usually needed when contributing video and audio via WAN or LAN to a broadcast production.

Video-over-IP Contribution via WAN

The Lawo V__remote 4 provides four 3G / HD/ SD SDI inputs and four 3G / HD / SD SDI outputs for interfacing to external video equipment. The device is designed to convert 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 via 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 a real network technology with multi-cast 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 in video quality and signal transport reliability.
The unit’s extremely robust J2K codec (with a special protection algorithm for signal transport even on unreliable WAN connections) and its SMPTE2022-7 compatible port redundancy ensure signal availability and quality. Lawo’s EPS technology for enhanced protection switching goes even further and enables system designs with true hardware and network redundancy. Format and quality of the IP video streams can be configured individually to meet the optimal ratio between picture quality, latency and bandwidth. The 6 Ethernet ports are connected to an internal switch allowing to “tunnel” through the 10GBit any IP traffic such as camera control, RAVENNA streams or even office and internet IP traffic.
