Abstract

A surveillance digital video recorder system comprises a microprocessor, a principal real-time picture processor module, a picture processor module, and a data storage module. The microprocessor controls the operations of the surveillance digital video recorder system. The principal real-time picture processor module receives a plurality of picture signals that are processed into a real-time multi-frame video signal. The picture processor module receives and processes the real-time multi-frame video signal and outputs a picture signal under the control of the microprocessor. The data storage module stores motion picture computer data obtained by the picture processor module from the real-time multi-frame video signal under the control of the microprocessor.

Claims

1. A surveillance digital video recorder system used to monitor a site, comprising:

a monitor that shows the monitored site;

a microprocessor that controls the operations of the surveillance digital video recorder system by outputting a control signal;

a principal real-time processor module that receives and processes a plurality of picture signals into a real-time multi-frame video signal;

a picture processor module that receives and processes the real-time multi-frame video signal and outputs a picture signal to the monitor, wherein the processing of the real-time multi-frame video signal and the picture signal output by the picture processor module depends on the control signal output by the microprocessor; and

a data storage module that stores pictures of the monitored site filmed by the surveillance digital video recorder system.

2. The system of claim 1, wherein the picture processor module comprises:

a motion picture computer data module that transforms the real-time multi-frame video signal into a motion picture computer data that can be stored in the data storage module;

a data storage interface that serves as a data transmission interface between the picture processor module and the data storage module; and

a multiplexer that designates the picture signal output by the picture processor modules as either the real-time multi-frame video signal or a picture signal obtained from the reading of the motion picture computer data stored in the data storage module, depending on the control signal output by the microprocessor.

3. The system of claim 1, wherein the data storage module is a hard disk.

4. The system of claim 1, further comprising a network interface component through which the motion picture computer data can be put onto a network.

5. The system of claim 2, wherein operations of the surveillance digital video recorder system controlled by the microprocessor comprise:

a record operation, a fast forward operation, a fast reverse operation, a normal play operation, and a stop operation.

6. The system of claim 5, wherein during a record operation, the picture signal output by the picture processor module via the multiplexer is the real-time multi-frame video signal, wherein the real-time multi-frame video signal also is transformed into motion picture computer datum that are stored in the data storage module.

7. The system of claim 5, wherein during a normal play operation, the picture signal output by the picture processor module via the multiplexer is from the motion picture computer datum stored in the data storage module.

8. The system of claim 5, further comprising a command board, the command board comprising:

a key that commands the record operation;

a key that commands the fast forward operation;

a key that commands the fast reverse operation;

a key that commands the normal play operation; and

a key that stops the fast forward operation, the fast reverse operation, the normal play operation or the record operation.

9. The system of claim 1, further comprising a plurality of real-time picture processor modules from which the picture signals are output to the principal real-time picture processor module.
