Maximising Signal Integrity And Reliability During Video Changeovers

In many broadcast applications, the ability to switch between two inputs or to choose between two outputs is essential, whether responding to a power failure or simply providing viewers with the most interesting shots from a fast changing outside broadcast.

LEN's 3G SDI Relay (L3GR01) for coaxial cables, supports data rates up to 3 GBits/sec and can be set-up to allow easy switching on failure of an incoming SDI signal from a remote source, ensuring the continuous broadcast quality feed, which is critical to the successful broadcast of a live event.

This cost effective, reliable relay switch is transparent to all 3G, HD, SD and ASI formats and can be utilised in conjunction with LEN's LMPR01 1U Rack Frame allowing up to 8 relays to be mounted on a 19 inch panel. As a leading provider of signal enhancement products, LEN products are trusted by professionals throughout the world and the LEN team pride themselves on offering the industry a portfolio of products well-suited to even the most demanding environments and LEN's relay switch range is no exception.

Unlike conventional matrix switchers, where maintaining the matrix requires good isolation, wide bandwidth and a low effect on current, LEN relay switches benefit from a higher open state, leading to lower leakage between contacts, which in turn means that signal integrity is safeguarded. This results in a highly reliable, broadcast quality feed during both planned and unexpected change-overs.
