Embodiment Construction

[0016] The improved control method of the digital image hard disk video recorder of the present invention adopts an embedded system or a PC-type system, and adds an analog switch to RS232 device inside the embedded system or the PC-type system, or a device that converts to the PC1 bus There are several ways for equipment or plug-in cards, corresponding to each operation button. There are 50 channels, for example. Each operating button is converted to RS232 device via analog switch, or converted to PCI bus or plug-in card corresponding to a signal sent to the PC, the DVR software in the PC will instruct the PC to take corresponding actions after receiving the signal.

[0017] The operation buttons are arranged on the panel. The operation buttons include buttons for pan / tilt control, lens control, and screen display mode, among which: the pan / tilt control has up, down, left, right, and auto buttons; the lens control has zoom, focus, and iris buttons; Screen button, high-definition d...

Abstract

The invention relates to an improved control method of a digital video recorder. The method includes arranging a device for connecting an analog switch to RS232 or arranging a device or a plug card for connecting the analog switch to a PCI bus in an embedded system or a PC system, and the device or plug card has routes corresponding to operation buttons. Each button can charge a signal to a PC via the device for connecting an analog switch to RS232 or the device or plug card for connecting an analog to a PCI bus, DVR software installed in the PC receives the signal and controls the PC to execute corresponding operation. The operation buttons are arranged on a panel and include platform control, lens control, and image display mode, and also include a function selecting button and a menu button. The invention is an improvement based on PC-type DVR control, has the advantages of high clearness and variability of PC-type DVR output, and has the convenience as the embedded DVR which adopts operation buttons for normal control.

Description

Technical field [0001] The invention relates to a digital image hard disk video recorder (DVR), in particular to an improved control method of a digital image hard disk video recorder. Background technique [0002] Digital image hard disk video recorder (DVR) has two basic forms, one is DVR with embedded system, and the other is DVR with Microsoft software platform and PC hardware platform. Comparing the two, the main differences are as follows: [0003] In terms of operation and control mode: the embedded type is a button, which is convenient to operate; the PC type is a keyboard and a mouse, which is inconvenient to operate. [0004] The speed of entering the DVR function: the embedded type is faster; the PC type is slower. [0005] Output definition: the embedded type is poor; the PC type is higher. [0006] Variability (such as adding other functional programs): Embedded type is impossible; PC type is easy and feasible. Summary of the invention [0007] The task of the prese...
