Enensys, designers and manufacturers of digital TV transmission technologies, as a
solution to the redundancy challenge provided by the huge growth in the use of IP
streams, has launched its new IPGuardV2. As well as its core redundancy
capabilities, the system also includes switching criteria specifically designed for the
broadcast and related media markets.
Jean-Baptiste Marie, product marketing engineer for Enensys said, “The whole
industry is now moving towards IP throughout the broadcast chain. A prime network
example is where once it was satellite from headend to transmitter, now it’s
increasingly IP. This is a global phenomenon. Of course, with increased usage
comes increased redundancy requirements. Successful redundancy is essential in
meeting service level agreements.’
IPGuardV2 provides automatic redundancy for all IP-based appliances and networks
and is designed for customers that need to secure IP stream transport or generation.
In order to provide the capacity and flexibility that the market now requires, IPGuardV2 is compatible with the company’s high density chassis and can be
purchased and installed in a modular way. In 1RU the chassis contains six product
modules, with each module able to handle 66 streams. This high density and huge
processing capabilities makes the product ideal for high stream count networks like
CATV and IPTV.
IPGuardV2 can provide 1+1 IP automatic stream redundancy for any IP-based
equipment (encoders, multiplexers, VoD servers, etc.). In the case of network
redundancy, IPGuardV2 can manage seamless redundancy of identical TS and T2-MI
streams coming from different network paths with different transport delays by
performing streams alignment. For instance, it can be used to provide redundancy
for streams to a remote site through both a fibre and an Ethernet network. It also
allows only specific affected streams to be replaced.
Finally, due to its bypass feature and the hot plug power supply, IPGuardV2
ensures 100 per cent service availability by preventing systems failures from
impacting successful delivery.
