Dejero unveils 1U vehicle-mounted transmitter

Designed to suit a variety of satellite and microwave truck applications, the LIVE+ VSET is new from video uplink technology specialist Dejero.  The newest member of Dejero’s LIVE+ platfrom, LIVE+ features an adaptive bit-rate encoder that provides ENG teams with a flexible way of reducing the latency and improving the reliability of IP-based satellite video feeds.

Essentially a rackmount version of Dejero’s portable LIVE+ 20/20 Transmitter, the LIVE+ VSET is designed for mounting in transmission trucks to provide a powerful supplement to satellite and microwave links. The LIVE+ VSET features Dejero’s Intelligent Bonding and Connection Management systems, which take advantage of the beneficial characteristics of all available connection types — cell, satellite, or microwave — to provide maximum throughput and optimal picture quality for each transmission. On startup, the LIVE+ VSET uses Dejero’s patent-pending approach to auto-detect the presence of available streams and the required video formats, with the ability to switch seamlessly between satellite and cellular or a combination of both in order to maintain the quality of the signal. During a typical satellite transmission, the LIVE+ VSET automatically combines a high-latency satellite connection with multiple low-latency cellular connections, resulting in the delivery of high-quality video with latencies of 1.5 seconds or less.

During rain fade and other atmospheric conditions that cause Ka-band satellite bandwidth to decrease, the LIVE+ VSET will automatically pick up the drop in bandwidth and continue the transmission over the cellular networks. Even in ideal conditions when the bulk of data is being sent over satellite, the LIVE+ VSET takes advantage of the lower latency of a cellular connection to check for and send missing packets, thereby leading to an overall decrease in latency on the entire Ka-based system.

The Dejero LIVE+ VSET also includes an easy-to-use front panel LCD display and an optional asynchronous serial interface (ASI) that supports a wide range of bit-rates, paving the way for quick and easy interconnection with microwave systems.
