Abstract
A bidirectional telemetry system for data transfer over relatively long distances such as, for example, within an oil or gas well. Data is transferred via cable such as a single conductor cable used for the transmission of various types of logging data including, but not limited to, video signals, pressure and temperature information. A video or other signal can be electronically converted into an amplified current modulated telemetry equivalent, transmitted along a cable having a varied impedance characteristics, and electronically converted back into a compliant voltage modulated composite video standard.
Claims1
A method for data telemetry comprising:
- a) converting a video signal electronically into an amplified current modulated telemetry equivalent;
- b) traversing a cable having a length and varied impedance characteristics with said current modulated telemetry equivalent;
- and
- c) converting said current modulated telemetry equivalent electronically into a compliant voltage modulated composite video standard.
