SSM-ATSC HDTV Modulator Card

The SSM-ATSC SignStream Modulator Card broadcasts 1080i and 720p ATSC Transport Stream files as an ATSC HDTV channel over standard RF coax systems.

Taking advantage of broadcasting's shift to digital HDTV technology, the SSM-ATSC is essentially a TV station on a PCI card. Unlike a conventional signage server, a SignStream server can support up to six SSM-ATSC cards, delivering up to six simultaneous HDTV signage channels. Moreover, each HDTV channel serves media at a full 19.4 Mbps data rate, far higher than most "HD" signage from conventional digital signage media servers.
