Inca Networks announced enhancements to extend Emergency Alert System (EAS) support in the company's IP-to-analog and IP-to-QAM Tangram modules for cable TV and IPTV operators. The expanded EAS support includes integration with Trilithic EAS and other manufacturers supporting the Common Alerting Protocol (CAP).
The upgrades are designed to let operators monitor and send out EAS signals to specific chosen video streams on both their analog and digital RF video networks.
Each Inca GT21 analog edge decoder, part of the modular WISI Tangram platform, is designed to ingest multiple HD or SD IP streams in either MPEG-2 or MPEG-4 format and convert them to NTSC modulated RF analog outputs for delivery to legacy analog TV networks. It's intended to allow operators to support legacy analog tiers of service while simplifying headend equipment and power consumption and integrating with IP video headend architectures.
Each Inca GT23 QAM modulator is designed to receive multiple IP single program transport stream (SPTS) or multiple program transport stream (MPTS) and distribute them on digital QAM carriers for use by digital TV sets. The GT23 EdgeQAM can co-exist in the same chassis as the GT21 analog edge card, allowing operators to support both legacy and IP video networks from a 1RU chassis.
