Venice is a media platform designed to manage complex signal processing and storage requirements, particularly in live studio production applications. It provides uninterrupted operations including scheduled recording, clip transforms and playouts, across a network of processors and both Rohde & Schwarz storage and third-party qualified storage sub-systems. It also bridges the SDI and IP environments. Venice servers can now be configured for multiple HD and Ultra HD signals, and units can work together as a single resource from a single user interface.
The high bandwidth of Ultra HD signal demands special handling, beyond the traditional 3G environment. Ultra HD infrastructures today are typically built around either 12G – a single, very high-bandwidth connection which has some technical limitations – or 2SI, which spreads the signal pixel-by-pixel across four conventional SDI cables. 2SI also provides a degree of resilience, as the loss of one channel simply means a drop in resolution, not a complete loss of all or part of the picture.
The Rohde & Schwarz Venice media platform now supports both 12G and 2SI, enabling it to fit comfortably into any environment. Because each Venice processor is software defined, a channel can easily switch between an Ultra HD signal and HD signals. With Venice sharing resources across a network from a single management user interface, it means resources can be allocated for maximum efficiency and utilisation.
The ability to achieve performance by making efficient use of the available hardware is one of the chief benefits of the Venice architecture. It allows resources to be shared, for instance through a method called Transform Channel Assignment, which allows a source to be recorded, viewed and processed – trimmed, merged or edited, for example – simultaneously, while making the optimum use of available resources. Using Record Scheduler, Venice looks ahead to ensure there are sufficient channels for planned recordings while serving current requests for access.
