Broadcasters, from local-area TV stations to program channels such as Mercury Studios, NBC, Fox News, CBS, Disney, ABC, WWE, TMZ, and The Home Shopping Network, employ HD-SDI as the standard for the studio. However, up to recently, they didn’t have a vehicle to deliver the HD studio feed to the rest of the facility. For most sites, the high-resolution studio feed was reduced to a low-resolution analog TV for distribution over RF.

With the introduction of our dual channel HDTV Modulators the QMOD-SDI 2 HDTV Modulator IPTV Encoder and the QMOD-SDI HDMI HDTV Modulators IPTV Encoder, broadcasters can share their live feed throughout their facility as an HDTV channel over Coax and IPTV. For the first time, guests, studio execs and staffers can view their programming in the same HD quality as their viewers. Applications can be as simple as one HD-SDI feed for the RF system, or a number of channels delivering HD video to multiple studios or green rooms.

Local broadcasters also use 232-ATSC 4 or ATSC+SDI 4  HDTV tuners to monitor the quality of their signal. The ATSC+SDI 4 has a native HD-SDI output that supports embedded captioning and audio. Both feature an IP Web page to easily support remote control and status.
