Problems solved by technology

[0006] However, the above-mentioned method has the following problems: although the images of many channels can be recorded once by linking video recording, it is not known which channel is linked to each other when playing, and each channel must be retrieved and played, so it is not only a waste of time, but also quite expensive. cumbersome
Especially, when an intruder is generated, it takes a lot of time until the intruder is identified from the video image

Abstract

A play control method for a digital video recorder connected with a monitoring camera is provided, which comprises: a step of generating link information related to the link channel when a user selects the link channel; a step of contacting the selected channel according to the link information when the user selects the video channel and recording the monitoring image of the channel linked thereof and the link information to a recording medium; and a step of reading and playing the selected channel and video image of the channel linked thereof according to the link information when the user selects the play channel. When a plurality of linked channels are recorded, the link information is stored at the same time and a plurality of linked videos are searched to play, so that the invention can solve the problem that the linked channel should be searched to play every day, resulting in time waste and complex operation; and can rapidly discriminate the invader from the video when the invader attacks.

Description

technical field [0001] The present invention relates to a playback control method of a digital video recorder, more specifically refers to: a digital video recorder connected with a monitoring camera can perform a search and playback of video images of many channels according to the link information for the link channel. method. Background technique [0002] Usually, surveillance cameras are installed in specific places (for example: banks, museums, etc.) that need to be monitored, so as to photograph relevant areas. For example, if figure 1 As shown, the surveillance camera (Camera) 100 photographs the object to be irradiated in the relevant area, and outputs it to a remote digital video recorder (DVR) 200 . [0003] Furthermore, the digital video recorder 200 outputs and displays the monitoring video captured by the monitoring camera 100 through a monitor screen, and at the same time records and stores it on a hard disk (HDD) or the like installed in the device. [0004...
