This fifth generation HDTV Tuner builds on the previous model, 232-ATSC 4, with video output scaling up to 4K, the ability to decode channels up to 1080p, and, in a future free firmware release, the option for IP streaming via Ethernet output. The 232-ATSC 4K is a commercial HDTV tuner that can receive both analog and digital off-air, analog, and clear QAM cable channels, controllable via RS-232, Ethernet, and IR. Full interactive control and configuration is also available from onboard Web pages. The 232-ATSC 4K is compatible with control systems from AMX, Crestron, Extron, RTI and others. At the same time, the new 232-ATSC 4K tuners are fully compatible with RS-232, Telnet, and IR commands for previous ATSC tuners. The 232-ATSC 4K HDTV Tuner replaces the 232-ATSC 4 HDTV Tuner and is now shipping.
