It crosses network and reaches the earth other end, and the viewer of distal end is not required to any professional software, as long as the web browser of standard is (such as
" Microsoft IE or Netscape) or matched client software can monitor its image.An embedded core built in IPC
Piece, using embedded real-time operating system.It is compressed after the video signal digitization of acquisition by Efficient Compression chip, it is total by network
Line sends client or management server to.
It is attached between NVR and IPC by IP tunnel.IP tunnel is the digital channel of NVR, can correspond to access IPC.One
A NVR can receive simultaneously the video record data from multiple IPC by multiple channels.
After NVR carries out the storage of video record data, client can obtain the data needed from NVR.As shown in Figure 1, being existing
There is the process flow of multi-channel video Video data:
NVR receives the video record data from each IP tunnel, is stored by the way of following: by each channel
Video record data are respectively stored in independent file according to the period, as shown in Fig. 2, channel 1 (i.e. IPC channel1)
Data be stored in m file, i.e., the record file-1 to record file-m of IPC channel2 is corresponded in figure；Class
As, the data storage of channel 2 (i.e. IPC channel2) also in m file, i.e., corresponds to IPC channel2's in figure
Record file-1 to record file-m；What is stored in the record file-1 file in each channel is that the period 1 is corresponding
Video record data, what is stored in record file-2 file is the corresponding video record data of period 2, and so on,
What is stored in record file-m file is the corresponding video record data of period m.
In the prior art, local video file includes multiple independent files, and each unique file stores a certain channel
The video record data of one period.When client need to carry out some or the multiple channel datas in some period it is long-range

As shown in figure 5, for the storage schematic diagram example of multi-channel video of the present invention video recording, HD recording equipment in the example
Body is NVR, and the data in channel 1 to N are constantly stored in local video file using time slice size as interval.And the time
The interval range of section can be set as needed, and include the video record data of at least one time slice in a period；Such as
Example shown in fig. 6 includes m seconds video record data in one period.In the example, NVR is in storage video file
When being stored, the bit stream data of multichannel is recycled according to very small time slice (1 second) and is successively stored, i.e., to every
Picture group data corresponding to 1 second Video data (GOP, Group of Pictures) data successively store；At the same time, exist
The corresponding channel information of affix in the GOP data, to identify the number for this second corresponding to GOP bit stream data being which IP tunnel
According to.According to this rule, NVR constantly adds the bit stream data that each channel is written to the tail portion of big file.
Step 403, the request of data from client is received, the request of data includes designated time period and dedicated tunnel
Mark.
When client needs to obtain data, request of data is sent to hard disk video recorder.The finger that the request of data includes
Routing is identified as one or more.

The bit stream data of channel or some combination of channels, therefore the video file being stored on local PC may also include multiple channels
Bit stream data.The data information of file is richer.
E, client parses and plays back video recording bit stream data:
It, may the code stream number comprising single channel or some combination of channels in bit stream data received by client
According to；At this point, client upper layer is additional to the correlated identities on each IP tunnel when can store video recording bit stream data according to NVR, know
Bit stream data that is other and parsing each corresponding channel in the code stream is then fed into decoding library and carries out data readback.
F, multichannel video recording synchronized playback:
Because NVR equipment, when storing bit stream data, the code stream information in each channel is by very small time slice pair
Code stream, which is recycled, successively to be stored, and is transmitted in transmission, and by this rule.If it is multi-channel data, client
It opens multiple threads to be decoded certain section of video recording code stream received, parses the bit stream data on all channels.Again to solution
The bit stream data separated out is played back (broadcasting) using multithreading, and the corresponding time segment information of the bit stream data on each channel can
To think almost actually to only exist extremely small error close to synchronization.
