High Density SDI/IP Gateway for Densité 3 Platform
Densité IP Gateway (IPG-3901) plug-and-play modules seamlessly bridge hybrid SDI/IP production environments. As broadcasters migrate to IP-based transport, these space-saving, low-power cards are easily added to existing Densité signal processing platforms, converting real-time, uncompressed, baseband video using SMPTE 2022-6 protocol for distribution over 10 GigE networks, and vice versa. The gateways support any mix of 3G/HD/SD-SDI production workflows over IP networks. With bidirectional I/O in combinations of 5 in/6 out or 6 in/5 out, the cards offer full redundancy in either unicast or multicast workflows to ensure uninterrupted service. The IPG-3901 with purchasable TICO option provides either two (2) encodes OR two (2) decodes OR one (1) encode and one (1) decode per card.
