Patent ID: 8823878

Claim:
A broadcast signal detection device comprising: a multi-layer printed circuit board; an isolation/buffer amplifier and terminator communicating with the multi-layer printed circuit board, the isolation/buffer amplifier and terminator appearing as a terminated device to a broadcast signal provided to the isolation/buffer amplifier; and a signal detection circuit comprising a first signal detector communicating with the isolation/buffer amplifier and attached to the multi-layer printed circuit board for detecting and reporting a type of broadcast signal provided to the isolation/buffer amplifier and selected from a group consisting of (ASI digital video signals, and SDI and HD-SDI digital video transport signals), the first signal detector further providing an ASI status line, a SDI status line, and a HD-SDI status line for reporting the type of signal detected when a signal is detected by the first signal detector; a second signal detector communicating with the isolation/buffer amplifier and attached to the multi-layer printed circuit board for detecting a NTSC analog video signal as the type of broadcast signal provided to the isolation/buffer amplifier, the second signal detector further providing a NTSC status line for reporting the type of signal detected when a signal is detected by the second signal detector; and a logic circuit attached to the multi-layer printed circuit board and communicating with each the NTSC, ASI, SDI, and HD-SDI status lines, and providing a NTSC output line.
