Further, above-mentioned digital media server also has feature below:
Described synchronous processing module, the character of the described correspondence of inquiry is need the type of synchronous data manipulation to comprise: increase, delete and amendment.
To sum up, the invention provides a kind of method and digital media server of data syn-chronization, can solve in current family DLNA device Interconnection Environment, multi-screen shares DMS data display can not the problem of real-time synchronization, realizes the real-time synchronization of multi-screen data.
Accompanying drawing explanation
Fig. 1 is the flow chart of the method for a kind of data processing of the embodiment of the present invention.
Fig. 2 is the schematic diagram of a kind of DMS of the embodiment of the present invention.
Embodiment
For making the object, technical solutions and advantages of the present invention clearly understand, hereinafter will be described in detail to embodiments of the invention by reference to the accompanying drawings.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combination in any mutually.
Fig. 1 is the flow chart of the method for a kind of data processing of the embodiment of the present invention, and as shown in Figure 1, the method for the present embodiment comprises:
Step 11, DMS receive the data manipulation of DMR request;
Step 12, type according to described data manipulation, determine whether initiate simultaneous operation to other DMR.
Multi-screen real-time synchronization more new data can be realized according to the method for the present embodiment.
Be described in detail with the method for a specific embodiment to a kind of data processing of the present invention below, comprise the steps:
When step 101:DMS starts, initialization DMS activity classification table and DMR operate mapping table, wherein, it is empty that DMR operates mapping table original records, only have and increase record again after DMR has carried out practical operation, actual operation can comprise: increase, delete, revise, inquire about and check the types such as judgement; Namely the initialization of DMS activity classification table comprises the character the action type that DMS can support and action type.
The action type that the upper energy of DMS is supported such as comprises: increase, delete, revise, inquire about and check the types such as judgement; The character of action type, namely this kind of operation upgrades the need of DMS real-time synchronization.
Table 1 is DMS operation mapping table, as shown in table 1, DMS records the operation note of DMR equipment to certain data type on DMS, the data on DMS have been only had when DMR Successful Operation just to increase the operation note of this DMR, just increase the operation note of this DMR, and after DMR equipment rolls off the production line, just the operation note of this DMR equipment is deleted.
Table 1
Table 2 is activity classification table, the data, services that DMS provides for self is classified, record the executable action type of data of the same type, and this kind of action type needs other DMR equipment of DMS synchronization notice, such as increase, delete, amendment action need DMS real-time synchronization notify other DMR equipment, and inquire about, check judgement operation do not need DMS real-time synchronization to notify other DMR equipment.
Table 2
| Data type | Data manipulation Class1 | Data manipulation type 2 | ...... |
| User collects data | Inquiry | Amendment | |
| User's subscription data | Delete | Increase |
Step 102: when DMR is to DMS data operation request, DMS checks and finds self to provide service to DMR, then to DMR response success, if can not meet the operation requests of DMR, then respond unsuccessfully to DMR;
Step 103: if DMS is to the DMR response success of request, then operates in mapping table to DMR, increase an operation note, record the address of DMR, the data type of operation, action type.
Step 104:DMS increases DMR and to operate in mapping table after record completing, need to inquire about self activity classification table, confirm that the operation of this DMR is the need of initiation DMR real-time data synchronization renewal rewards theory, if this time operation of DMR is inquiry and inspection judge type, then do not need to initiate real-time data synchronization renewal rewards theory; This time DMR operation is the operation of the types such as increase, deletion, amendment else if, needs to initiate real-time data synchronization renewal rewards theory.
Step 105: if need to initiate real-time synchronization renewal rewards theory, DMS needs inquiry DMR to operate mapping table, and inquire about the record the same with this deal with data type, find other multi-screen DMR address, multi-screen DMR refers to multiple terminal or multiple client here;
The operation note that have recorded DMR in mapping table is operated at DMR, but the collection data of user operation that what this operation note may be recorded is, what also likely record is the broadcasting bookmark record data of user operation, that also likely record is the inquiry VOD(Video On Demand of user operation, video request program) table data.Synchronized update operation is corresponding same type data, such as user operation broadcasting bookmark record data, then need to notify that other users play bookmark data and need to upgrade, and if the current bookmark data that all do not operate of other users, then do not need to this user notification.
Step 106: according to the DMR address inquired, DMS sends event notice DMR more new data to it;
Step 107: multi-screen DMR receives Data Update notice, shows, the more display of new data according to actual pages.
Fig. 2 is the schematic diagram of a kind of DMS of the embodiment of the present invention, and as shown in Figure 2, the DMS of the present embodiment comprises:
Receiver module, for receiving the data manipulation of digital media receiver request;
Synchronous processing module, for the type according to described data manipulation, determines whether initiate simultaneous operation to other digital media receivers.
In a preferred embodiment, described DMS also comprises:
Logging modle, for by the class record of the address of described digital media receiver and described data manipulation in preset operation mapping table.
Wherein, described synchronous processing module, specifically for the activity classification table preset according to the type queries of described data manipulation, character as corresponding in the type of data manipulation as described in inquiring is synchronous for needing, then initiate simultaneous operation to other digital media receivers, otherwise do not initiate simultaneous operation to other digital media receivers.
Wherein, described synchronous processing module, the character of the described correspondence of inquiry is need the type of synchronous data manipulation to comprise: increase, delete and amendment.
The all or part of step that one of ordinary skill in the art will appreciate that in said method is carried out instruction related hardware by program and is completed, and described program can be stored in computer-readable recording medium, as read-only memory, disk or CD etc.Alternatively, all or part of step of above-described embodiment also can use one or more integrated circuit to realize.Correspondingly, each module/unit in above-described embodiment can adopt the form of hardware to realize, and the form of software function module also can be adopted to realize.The present invention is not restricted to the combination of the hardware and software of any particular form.
These are only the preferred embodiments of the present invention; certainly; the present invention also can have other various embodiments; when not deviating from the present invention's spirit and essence thereof; those of ordinary skill in the art are when making various corresponding change and distortion according to the present invention, but these change accordingly and are out of shape the protection range that all should belong to the claim appended by the present invention.
