Grass Valley Opens Gateway to IP Migration at Broadcast Asia

The new NVISION 8500 IP Gateway input/output card converts and packetizes real-time, uncompressed, baseband video for multi-directional transport over 10 Gb Ethernet networks. SDI signals are then packetized, and can be distributed from rack-to-rack, truck-to-truck or between floors, buildings or campuses - over an IP network, supporting multiviewer, ingest, playout, modular and monitoring infrastructure. Frame-accurate switching from SDI to IP contributes to signal integrity, and the non-blocking architecture of the cards gives access to all crosspoints within the NVISION 8500 Series router.

Existing NVISION 8500 routers can be upgraded to support the new card. 10 GbE Ethernet tie lines between core and production island routers enable IP Gateway-equipped NVISION 8500 routers to establish a straightforward transformation to high-speed networking for data and content transport. An important aspect of the NVISION 8500 IP Gateway card is that broadcasters can make the IP transition with no loss of service, and it can be updated later whenever communications standards and requirements move on.


The new IRG-3401 IP Gateway has also been developed to support cable, satellite and IPTV operators' migration towards to IP. It is a very high density, flexible and integrated bi-directional DVB-ASI/IP gateway handling up to 120 gateways in a single 3 RU frame, which accommodates numerous potential applications including IP jitter removal, a major quality of service factor in network performance. It can bridge most types of MPEG transport stream from or to IP networks.
Grass Valley’s senior vice president for the Asia Pacific region Stephen Wong said, “Broadcast infrastructure requires the reliable performance of its components, but traditional SDI-based facilities have a potential for multiple points of failure when diverse systems need to work together. A properly specified IP-based infrastructure can not only reduce the potential for errors, but can also improve efficiency and flexibility.”

For IP infrastructure monitoring the updated, high density Kaleido-IP X310 multiviewer extends the level of monitoring support for this platform to 128 SD or 64 HD programs with double the number of simultaneous audio and video decodes as the previous version, at half the size. Decodes include MPEG-2, H.264/AVC, AAC, AC-3 and MPEG-1.

Kaleido-IP monitors local and remote IP multicast streams, either in single or multi-program transport stream formats, and it uses probing and alarming to keep track of video and audio faults including freeze, black and silence. A cluster function supports combining of multiple units to support larger monitoring requirements.
