Appl. No.:

10/392658

Inventors:

Mohammad Alkhalili - Dumont NJ, US
David Rowe - Campbell Hall NY, US

Assignee:

Pelco - Clovis CA

International Classification:

H04N 5/04
H04N 5/06

US Classification:

348537, 348536, 348512, 327156

Abstract:

A pixel clock generating circuit is provided in which a digital circuit generates a first signal corresponding to the relative frequency of the pixel clock as compared with a predetermined desired pixel clock frequency. An analog circuit is electrically coupled to the digital circuit in which the analog circuit has a reverse biased variable capacitance device, an integrator and a comparator circuit. The reverse biased variable capacitance device has an anode and a cathode. The integrator has an input coupled to the digital circuit and an output coupled to the cathode of the reverse biased variable capacitor. The integrator is arranged to integrate the first signal received from the digital circuit and produce an output voltage across the reverse biased variable capacitance device such that the output voltage causes the capacitance of the reverse biased capacitor to change if the pixel clock is not operating at the predetermined desired pixel clock frequency. The comparator circuit is electrically coupled to the anode of the reverse biased variable capacitor and produces the pixel clock having a frequency based on the capacitance of the reverse biased capacitor.

Appl. No.:

10/115113

Inventors:

David Rowe - Campbell Hall NY, US

Assignee:

Pelco

International Classification:

H04N017/00
H04N007/18

US Classification:

348/181000, 348/143000

Abstract:

A device and method are provided device for generating a test pattern on a video display unit having a first quantity of raster scan lines, in which there is a logic processor and a memory. The memory is electrically connected to the logic processor. The memory stores test pattern data corresponding to a second quantity of raster scan lines in which the second quantity of raster scan lines is less than the first quantity of raster scan lines. The memory provides a digital video signal output.

International Classification:

H04N005/76

US Classification:

348/231200

Abstract:

A synchronization signal generating apparatus and method in which an input circuit is inductively coupled to an alternating current signal line. The input circuit generates a rectified signal. A switch has a switch input and a switch output in which the switch input is electrically connected to the input circuit and is enabled when the voltage of the rectified signal is greater than a predetermined voltage and is disabled when the rectified signal voltage is less than the predetermined voltage. A pulse generating circuit has a pulse generating circuit input and a pulse generating circuit output. The pulse generating circuit input is electrically connected to the switch output. The pulse generating circuit generates a pulse each time the switch is enabled. The synchronization signal generating apparatus is used in a synchronized television display system to signal a video switch to switch the video signal generated by a camera to a monitor based on the occurrence of the synchronization signal.

Abstract:

A video switching and control system is described that provides compatibility with conventional analog cameras while also accepting network IP type cameras. The system offers reduced control latency, improved recording efficiency, and more flexible display features with greatly improved performance and update rates.The system offers greatly reduced wiring and installation complexity thus improving reliability. The architecture is scalable and expandable in either the analog camera count or the IP camera count. The system integrates these two camera technologies so that the camera source or recorder is transparent to the user. Each user can control all video sources, analog, IP, or recorded, from one keyboard and one or more monitors at each work station.The unique all digital solution provides digital reliability and broadcast quality performance. The solution is significantly smaller and substantially lower cost the previous solutions, and offers higher monitor output capacity without the need for expensive down framing approaches currently used in the industry.
