The ATSC-SDI 4 is the first HDTV Tuner that features a native HD-SDI port, as well as MPEG2 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.
