20110063507 | AUTOMATIC VIDEO FORMAT IDENTIFICATION SYSTEM - A video format identification system includes a master clock circuit which provides timing and counting signals, a synchronization activity detector operatively coupled to the master clock circuit, and a synchronization width qualifier configured to filter out noise or reference burst signals from showing up as sync signals. The system also includes a synchronization detector which regulates the rate of the incoming sync signal, a color burst sampler providing a window for sampling a reference color burst after the sync signal has occurred, and a color burst detector which looks for at least three transitions from a burst signal before it qualifies the as an appropriate reference color burst. A format sample timer generates sample clock signals. A format sample counter produces “take format” signals which are utilized by a set of format counter. The system further includes a video format identifier which enables a particular video format to be directed to a respective video connector. | 03-17-2011 |
20110069236 | METHOD AND APPARATUS FOR DC RESTORATION USING FEEDBACK - A feedback circuit for restoration of DC in video signals is presented. A sample pulse representing the back porch of an incoming video signal is generated from the horizontal sync signal. The sample pulse triggers a sample and hold circuit to acquire the correct offset voltage in the output signal during this back porch period. The offset voltage feeds back through a summing node upstream of either the circuit causing the offset or an input amplifier thereby restoring the video signal to the desired DC voltage level with respect to ground. | 03-24-2011 |
20110128447 | METHOD AND APPARATUS FOR AUTOMATIC REDUCTION OF NOISE IN SIGNALS TRANSMITTED OVER CONDUCTORS - A method and apparatus for automatic reduction of noise in video signals transmitted over conductors is presented. The present invention provides an adjustable amount of noise filtering matched to the amount of gain provided by an adjustable gain amplifier to a received video signal. One or more stages of a multi-stage discrete gain amplifier is provided with a corresponding noise filter circuit. The filter circuit is matched to the frequency response of and the amount of gain provided by the discrete gain amplifier stage. When the amplifier stage is applied to the received signal, the corresponding noise filter for that stage is invoked as well. In that manner, the amount of noise filtering applied to a video signal automatically varies with the amount of amplification provided to that signal. | 06-02-2011 |
20120194746 | METHOD AND APPARATUS FOR DC RESTORATION USING FEEDBACK - A feedback circuit for restoration of DC in electrical signals is presented. A sample pulse representing a DC portion of an electrical signal is generated. The sample pulse triggers a sample and hold circuit to acquire the correct offset voltage in the electrical signal during this DC portion. The offset voltage feeds back through a summing node to the electrical signal thereby restoring the video signal to the desired DC voltage level with respect to ground. | 08-02-2012 |
20140055680 | METHOD AND APPARATUS FOR AUTOMATIC COMPENSATION OF SIGNAL LOSSES FROM TRANSMISSION OVER CONDUCTORS - A method and apparatus for automatic compensation of insertion loss in signals transmitted over conductors is presented. The present invention is particularly applicable to the transmission of signals over long lengths of CAT-5 or similar twisted-pair cables. A reference signal having a known form and strength (e.g. a pulse signal) is provided to each pair of conductors carrying a component of a signal from a transmitter to a receiver. The receiver includes adjustable gain amplifiers for each conductor pair over which a component of the signal is transmitted. The gains of the amplifiers are initially set at an initial level (e.g., their maximum gain) to allow detection of the reference signal. Once the reference signal is detected in a conductor pair, the amplifier gains are adjusted such that the level of the reference signal is restored approximately to its original form and strength. | 02-27-2014 |
