IBC2017: GatesAir to offer IP data protection and bandwidth efficiency

GatesAir, a global provider of wireless, over-the-air content delivery solutions for radio and TV broadcasters, will unveil at IBC2017 enhancements to two of its recently introduced Intraplex intelligent networking solutions that will advance the possibilities of IP-based signal transport for radio broadcasters.

The two products, Intraplex IPConnect software and the IP Link MPXp codec, will receive their international debuts at booth 8.C30.

Intraplex IPConnect is a new software application designed to fortify data transport across IP networks. Available as an option in most Intraplex IP Link codecs, IPConnect solves the problem of reliable transport across complex networks that traditionally suffer data loss through dropped packets.

GatesAir will also demonstrate how IPConnect provides an added layer of reliability for DAB/DAB+ and DRM IP streams by employing a combination of packet-protection schemes with network/time diversity and packet-level forward error correction. In addition, IPConnect can now bridge local area network (LAN) segments across wide-area networks with seamless tunnelling to enhance reliability of program and signal transport across very large geographical regions with multiple receiving and transmitting sites — an especially attractive benefit for national DAB/DAB+ broadcasters and network operators.

“Digital radio streams are particularly vulnerable to packet loss, given the large amount of data moving over many paths and across very long distances,” explains Keyur Parikh, director, GatesAir Intraplex Business Unit.

“IPConnect plays an important role in minimising susceptibility to packet loss, ensuring that valuable on-air content and control-based commands are not lost along the way. Reliability is further improved through the ability to tunnel all IP data between one or more sites, without concern of outside interference.”

IPConnect’s software data gateway provides extra protection through packet encapsulation, which encloses the external IP data packets in a GatesAir protocol wrapper as it moves across IP networks. Unlike many similar applications, the company says IPConnect provides this protection for studio-generated data, as well as IP data from external sources. While the former might include RDS data or SNMP control signals to trigger a command at the transmitter site, the latter may incorporate program or control data coming from a network operations centre, satellite feed or advertising service.

As the next-generation GatesAir Intraplex IP Link codec, the award-winning Intraplex IP Link MPXp leverages the strengths of previous IP Link codecs and adds new efficiencies. This includes GatesAir’s Dynamic Stream Splicing technology to mitigate IP packet loss and eliminate off-air time, forward error correction, and a trio of network interfaces for optimal stream reliability while empowering broadcasters with more signal transport options from a single box at historically low bitrates.

While the initial release in April this year cut the industry-standard bandwidth consumption for uncompressed AES 192 digital composite signal transport in half, the latest release further reduces those bitrates from the already industry-low 1.8Mbps to an even more efficient 1.65Mbps. This bandwidth-efficiency opens more headroom for increased packet protection, as well as additional audio and data services.
