Embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the embodiment of the invention is described in further detail below in conjunction with the drawings and specific embodiments.
The invention provides a kind of video recording playback method, as shown in Figure 2, comprise the steps:
S101, the mapping relations of sign ID, nas server IP address and the catalogue of configuration DVR;
S102 according to described mapping relations, searches nas server IP address and the catalogue corresponding with the ID of target DVR;
S103 is connected to corresponding nas server by described IP address, and the video file of selecting from the described catalogue of described nas server is play.
Below by specific embodiment said method is described in detail.
Embodiment one
Present embodiment provides a kind of video recording playback method, as shown in Figure 3, may further comprise the steps:
S201, the mapping relations of ID, nas server IP address and the catalogue of configuration DVR.
The ID of described DVR can be any numbering or the code that can distinguish DVR, for example the MAC of DVR (Media Access Control, medium access control) address, IP address, user-defined name etc.Described catalogue is the memory space of nas server for the video file of each DVR distribution.Described mapping relations can be configured on the network side data storehouse, are easy to realize the mapping relations data of storage are carried out dilatation; Also can be configured in monitor client this locality, seek rate can be sooner and is not subjected to the restriction of network side data storehouse fault thus.
Certainly, for the fixing supervisory control system of the corresponding relation of ID, nas server IP address and the catalogue of DVR, also can be when initial framework supervisory control system, for each DVR wherein specifies nas server and catalogue, and in monitor client or network side data storehouse the mapping relations of ID, nas server IP address and the catalogue of storage DVR.
S202 according to described mapping relations, searches nas server IP address and the catalogue corresponding with the ID of target DVR.
1) be configured in the situation in network side data storehouse for mapping relations, describedly search nas server IP address and catalogue specifically can comprise:
Monitor client sends the ID of described target DVR to the network side data storehouse;
Nas server IP address and the catalogue corresponding with the ID of target DVR are searched according to ID, the IP address of nas server and the mapping relations of catalogue of the DVR of configuration in the network side data storehouse;
Described monitor client is returned described nas server IP address and catalogue in the network side data storehouse.
2) be configured in the situation of monitor client this locality for mapping relations, describedly search nas server IP address and catalogue specifically can comprise:
Monitor client is searched nas server IP address and the catalogue corresponding with the ID of target DVR according to ID, the IP address of nas server and the mapping relations of catalogue of the DVR of this locality storage.
S203 is connected to corresponding nas server by described IP address, and the video file of selecting from the described catalogue of described nas server is play.
Wherein, described by the IP address be connected to corresponding nas server preferably can for: monitor client is by the path of the above catalogue of nas server of the described IP of mapping network driver carry address, for example set up mapping by API (Application Programming Interface, application programming interfaces).So after the operation, the described catalogue of described nas server can be mapped as local drive, be convenient to visit.
Afterwards, the user can see the catalogue at the video file place that described DVR records at monitor client, and then can select the video file in the catalogue to play.
Because the back method of present embodiment; pattern for DVR video recording, nas server storage; when the video file playback, need not visit DVR; monitor client can be according to ID, the IP address of nas server and the mapping relations of catalogue of the DVR that disposes; find nas server corresponding and catalogue, directly visit described nas server, from described catalogue, select video file to carry out playback with DVR; when monitor client can't connect DVR, ensured the normal playback of video file.The method of present embodiment can start when monitor client can't be connected with target DVR, also can all just often use at target DVR and network.
Before step S201, can also comprise step S201a: monitor client obtains nas server IP address and catalogue from described target DVR after connecting with target DVR.
Monitor client obtains nas server IP address and catalogue specifically can comprise from target DVR:
Monitor client sends the request of obtaining nas server IP address and catalogue to target DVR; Target DVR returns the nas server IP address of carrying promising its service and the response of catalogue.
Described request can be that monitor client sends to the message that target DVR plays video file, utilize the spare field in an extended field or the former message to carry the indication of obtaining nas server IP address and catalogue, extended field wherein can be positioned at the last of message body; Described request also can be a new message, and this message has the ID corresponding with obtaining nas server IP address and catalog function.Corresponding, described response can be after target DVR receives described request, what generate carries described ID, successful flag bit and is the nas server IP address of own service and the response message of catalogue, and the relevant information that described successful flag bit is used to notify monitor client to obtain nas server IP address and catalogue successfully.
During can normally be connected between monitor client and target DVR, monitor client can be by the mode of prior art, be that monitor client is to target DVR request video file Media Stream, target DVR is transmitted to monitor client read the Media Stream of video file from nas server after again, simultaneously, monitor client also can be to target DVR request nas server IP address and catalogue, according to nas server IP address and the catalogue that target DVR returns, the mapping relations of ID, nas server IP address and the catalogue of configuration target DVR.Monitor client can be regularly to nas server IP address of target DVR request and catalogue, also can connect with target DVR at every turn and afterwards ask once.This mode that dynamically updates can be adapted to the situation of the nas server change of target DVR service.
The back method of present embodiment; pattern for DVR video recording, nas server storage; when the video file playback, need not visit DVR; monitor client can be according to ID, the IP address of nas server and the mapping relations of catalogue of the DVR that disposes; find nas server corresponding and catalogue, directly visit described nas server, from described catalogue, select video file to carry out playback with DVR; when monitor client can't connect DVR, ensured the normal playback of video file.
