The ATSC-SDI 4 is the first HDTV Tuner that features a native HD-SDI port, as well as MPEG-2 and H.264 decoding. It 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.

The integral HD-SDI output allows inclusion of 708/608 captioning, choice of PCM stereo or AC-3 audio, and scaled output set to a constant 1080p, 1080i, 720p, or 480i resolution.

A universal TV tuner, the ATSC-SDI 4 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.
