The ATSC+SDI is the first HDTV Tuner that features an onboard HD-SDI port. A professional HDTV tuner, the ATSC+SDI is controllable via RS-232, IP, and IR commands. An onboard Web page enables remote Web control. A new menu-driven display simplifies setup, and a front-panel USB port makes firmware updates a snap. The new compact enclosure allows mounting of two tuners in a single rack space.
Having a built-in HD-SDI port offers several advantages over HDMI to SDI interfaces:
  • 708 captioning data is included in the stream (HDMI does not pass captioning data)
  • Audio can be set to AES stereo or AC3 regardless of channel audio
  • An internal scaler locks SDI output to a fixed standard; 1080i, 720p, or 480i
A universal TV tuner, the ATSC+SDI  can receive both analog and digital channels, in ATSC, NTSC, and clear QAM formats. Using an optional RF switcher, the tuner can switch between Antenna and Cable feeds.
The tuner displays broadcasts through simultaneous HD-SDI, Component, and Composite video outputs, as well as digital optical/coax ports, and variable-level stereo audio outputs.
