From Bonded Cellular ENG to BAS, new systems use variety of transmission methods
James Careless of TV Technology wrote a great article on Bonded Cellular ENG published in the July issue of TV Technology magazine. Here is an excerpt:
“OTTAWA—One good idea begets another: cellular bonding— sending compressed H.264 video from the field over multiple cellular telecom channels, to provide master control with a reliable live feed—has provided TV broadcasters with a highly portable, low-cost alternative to microwave and satellite transmission for a decade. It’s proven to be such a good idea that broadcasters and transmitter manufacturers alike have not only embraced “cellular ENG,” but taken it to the next level.
Today, this includes converting the outgoing feeds into IP video (making it seamlessly transportable across Wi-Fi and Ethernet networks), and also sending out these signals via licensed radio bands, allowing broadcasters to create their own private cellular ENG networks. For broadcasters of all sizes, this means that cellular ENG equipment is doing much more than just providing cost-effective, highly portable live TV feeds from anywhere; including places that microwave/SNG trucks just can’t go…”
“…Vidovation has partnered with France’s Aviwest to distribute the Aviwest bonded IP and bonded cellular platform in the United States. Aviwest is the most popular ENG supplier in Europe, according to Jim Jachetta, executive vice president of engineering and CTO for Vidovation. “Their equipment is the best in the market, and it conforms to European RF safety standards, which are tougher than ours.” Aviwest’s cellular ENG transmitter comes with dual hardware encoders for two independent transmission paths (one variable for bonded cellular transmission, and one fixed-rate); on-camera video recording for store and forward; and the ability to receive, decode and play out live streams from multiple field units.”
