Broadcast transmission relay circuit
First Claim
1. A transmission relay circuit for relaying a broadcast signal generated by a broadcast provider to a local loop provider, the transmission relay circuit comprising:
- a microcontroller; and
a broadcast signal sensing and discerning circuit communicating with the microcontroller and configured for sensing and reporting a broadcast signal type of the signal received from the broadcast provider, wherein the broadcast signal sensing and discerning circuit comprises;
an isolation/buffer amplifier communicating with the broadcast signal generated by the broadcast provider;
a signal detector portion communicating with the isolation/buffer amplifier for detecting a type of broadcast signal generated by the broadcast provider;
a logic circuit portion communicating with the signal detector for receiving a signal from the signal detector corresponding to the type of broadcast signal detected by the signal detector; and
a relay responsive to the logic circuit and providing an output signal corresponding to the type of broadcast signal detected by the signal detector.

Abstract
A transmission relay circuit, a broadcast signal relay method, and a signal detection device are disclosed. Preferably, the transmission relay circuit includes a microcontroller, a broadcast signal sensing and discerning circuit configured for determining the broadcast signal selected from a group consisting of (NTSC, ASI, DS-3, SDI, and HD-SDI signals). The method preferably includes the steps of determining a signal type, directing the signal to an analog broadcast signal processing circuit when the signal is determined to be to be an analog video signal, directing the signal to a digital broadcast signal processing circuit when the signal is either a digital video signal, or a digital video transport signal, and relaying the processed signal to a local loop provider. The detection device preferably includes at least a multi-layer printed circuit board with an isolation/buffer amplifier and terminator, and a signal detection circuit for detecting and determining the broadcast signal type.
