At the 2013 NAB Show, Contemporary Research will highlight its ATSC+SDI HDTV tuner. The professional HDTV tuner features an onboard HD-SDI port and is controllable via RS-232, IP and IR commands.
Additional features include an onboard web page, which enables remote web control; a new menu-driven display designed to simplify set-up; and a new compact enclosure that allows mounting of two tuners in a single rack space. The ATSC+SDI is field-updatable via USB.
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.
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.
