Embodiment Construction

[0016] The improved control method of a digital image hard disk video recorder of the present invention adopts an embedded system or a PC system, and an analog switching value is added to the RS232 device inside the embedded system or the PC system, or a device for converting the PC1 bus There are several channels for equipment or plug-in cards, corresponding to each operation button. The number of paths is, for example, 50. Each operation button is transferred to the RS232 device through the analog switch, or the device or card transferred to the PCI bus corresponds to a signal sent to the PC, and the DVR software in the PC will instruct the PC to take corresponding actions after receiving the signal.

[0017] Operation buttons are provided on the panel. The operation buttons include PTZ control, lens control, screen display mode and other buttons, among which: PTZ control has up, down, left, right, automatic buttons, lens control has zoom, focus, aperture buttons, and scree...

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 for a digital image hard disk video recorder. Background technique [0002] There are two basic forms of digital video recorder (DVR), one is a DVR using an embedded system, and the other is a DVR using a Microsoft software platform and a PC hardware platform. Comparing the two, the main differences are as follows: [0003] In terms of operation control mode: the embedded one is a button, which is easy to operate; the PC type is a keyboard plus a mouse, which is inconvenient to operate. [0004] The speed of entering the DVR function: the embedded one is faster; the PC one is slower. [0005] Output clarity: Embedded is worse; PC-style is higher. [0006] Variability (such as adding other functional programs): Embedded is not possible; PC-style is easy and feasible. Contents of the invention [0007] The task of the present inventi...
