[0079] see figure 1 , the flow chart of the first embodiment of the video recording method of the application DVR:

[0080] Step 101: Detect video input channels in real time.

[0081] Step 102: When it is detected that there is no video input in the channel, stop recording the channel, and when it detects that the video input resumes in the channel, start recording the channel, and end the current process.

[0082] Specifically, when it is detected that there is no video input in the channel, it is judged whether the channel continues to have no video data input within the preset time, and if there is no video data input continuously within the preset time and the channel starts recording, stop recording the channel ; When the video recording of the channel is stopped, if it is detected that the video input resumes in the channel, it is judged whether there is continuous video data input within the preset time, if there is continuous video data input within the preset time a...

[0083] see figure 2 , is the flow chart of the second embodiment of the video recording method of the application DVR:

[0084] Step 201: Preset the priority sequence of recording types, recording schedules and recording encoding parameters corresponding to each recording schedule.

[0085] Among them, the order of priority from high to low includes stop recording without video, manual recording, event recording and timing recording, corresponding to no video stopping recording mode, manual recording mode, event recording mode and timing recording mode respectively; the recording schedule includes timing recording Schedule and event recording schedule, recording encoding parameters include timing recording encoding parameters and event recording encoding parameters.

[0086] Step 202: Detect video input channels in real time.

[0087] Step 203: Determine whether no video input is detected in the channel, if yes, execute step 206; otherwise, execute step 204.

[0165] see Figure 10A , is the block diagram of the first embodiment of the application DVR:

[0166] The DVR includes: a detection unit 1010 and a control unit 1020 .

[0167] Wherein, the detection unit 1010 is used to detect the video input channel in real time;

[0168] The control unit 1020 is configured to stop video recording of the channel when no video input is detected in the channel, and start video recording of the channel when video input resumes in the channel is detected.

[0169] see Figure 10B ,for Figure 10A Example block diagram of the control unit:

[0170] The control unit 1020 includes:

[0171] The input judging subunit 1021 is used for judging whether the channel continues to have no video data input within a preset time when no video input is detected in the channel;

[0172] The video recording control subunit 1022 is configured to stop video recording of the channel if there is no video data input continuously within the preset time and the ...

Abstract

The invention discloses a recording method of a digital hard disk recorder (DVR) and a DVR. The method comprises the steps of: detecting the video input passage on real time; when video is not input in the channel during detecting, stopping recording the channel; when the video input is restored in the channel during detecting, starting to record the channel. In the embodiment of the invention, after starting the video and stopping recording, the record control can be flexibly carried out according to the condition that video is input in the channel, thereby saving the occupation of the unavailable record in the hard disk space; moreover, for respectively configuring a fixed-time recording schedule and an affair record schedule, and arranging the dispatch priority order of various recording mode, the recording type can be effectively classified and various recording mode cannot be overlapped, thus the flexibility and accuracy of recording are further improved.

Description

technical field [0001] The present application relates to the technical field of video processing, in particular to a DVR (Digital Video Recorder, digital video recorder) video recording method and the DVR. Background technique [0002] DVR is a monitoring device that can record video and audio data through the data hard disk. It has the functions of storing video, video playback, superimposing text, uploading alarm information and data, remote retrieval video, remote playback, remote download video, remote voice intercom, etc. . DVRs are divided into ordinary digital hard disk video recorders (only analog cameras can be connected), hybrid digital hard disk video recorders (Hybrid DVR) and network hard disk video recorders (NVR). In the prior art, when the DVR is recording, the recording compression encoding parameters and the recording schedule are preset. After the device is started, the device will automatically start or stop recording according to the time and condition...
