Abstract
Systems and methods are provided for communicating a data signal. A data signal is transmitted along a communications line. The transmitted data signal is split among a plurality of routers, each router configured to receive the data signal and forward the data signal along one or more output data paths. The data signal is received at a destination, and flat-band amplification is provided to the received data signal via a selectable gain amplifier. A frequency dependent amplification is provided to the received data signal via an equalizer. The amplified received signal is then decoded.
Claims20
A method of communicating a data signal, comprising:
- transmitting the data signal along a communications line;
- splitting the transmitted data signal among one or more routers, each router configured to receive the data signal and forward the data signal along one or more output data paths;
- receiving the data signal at a destination;
- providing flat-band amplification to the received data signal via a selectable gain amplifier;
- providing frequency dependent amplification to the received data signal via an equalizer;
- and
- decoding the amplified received data signal.
A method of receiving a serial digital interface (SDI) signal at a launch swing independent receiver, comprising:
- receiving an SDI signal transmitted at a launch swing below a prescribed launch swing standard;
- detecting that the received SDI signal was transmitted at the launch swing below the prescribed launch swing standard;
- providing flat-band amplification to the received SDI signal via a selectable gain flat-band amplifier;
- providing frequency dependent amplification to the received SDI signal via an equalizer;
- and
- decoding the amplified received SDI signal.
A system for communicating a data signal, comprising:
- a transmitter configured to transmit a data signal along a communications line;
- one or more routers among which the transmitted data signal is split, each router configured to receive the data signal and forward the data signal along one or more output data paths;
- a receiver configured to receive the data signal at a destination;
- a selectable gain amplifier configured to provide flat-band amplification to the received data signal;
- an equalizer configured to provide frequency dependent amplification to the received data signal;
- and
- a decoder configured to decode the amplified received data signal.
A system for applying selectable pre-amplification to a serial digital interface (SDI) signal, comprising:
- an launch swing independent SDI signal receiver configured to receive an SDI signal from a connected co-axial cable transmission line, the SDI signal receiver further including:
- a transmission launch swing detector configured to detect whether the received SDI signal was transmitted at a launch swing below a prescribed launch swing standard;
- a flat-band amplifier configured to amplify the received SDI signal according to a selectable gain upon detection that the received SDI signal was transmitted at the launch swing below the prescribed launch swing standard;
- an equalizer configured to provide frequency dependent amplification to the received SDI signal;
- and
- a decoder for decoding the amplified received SDI signal.
