Technical field

The present invention relates to the field of communications technologies, and in particular, to a data synchronization method and a digital media server. Background technique

DLNA (DIGITAL LIVING NETWORK ALLIANCE) is designed to enjoy music, pictures and videos anywhere, anytime. At present, DLNA technology is a relatively new business. Products supporting DLNA standards, such as TVs, stereos, set-top boxes, mobile phones, tablets (tablets), PCs (personal computers) and other home appliances, can be easily connected via wired or wireless networks. Interoperability and high resource sharing. For the user, there is no need to make complicated settings.

UPnP (Universal Plug and Play) is the core part of the DLNA network protocol suite designed for ease of use. It is the most common way for devices to connect to DLNA networks. It is a common device for devices to communicate over DLNA networks. protocol. UPnP is built on widely accepted and commonly used Internet protocols, and devices from different vendors can work together very easily, enabling content sharing and computing "anytime, anywhere." UPnP defines the interoperability mechanism between DLNA network devices in terms of addressing, searching, controlling, event, and performance.

Preferred embodiment of the invention

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments in the present application may be arbitrarily combined with each other.

FIG. 1 is a flowchart of a method for data processing according to an embodiment of the present invention. As shown in FIG. 1, the method in this embodiment includes:

Step 11. The DMS receives the data operation requested by the DMR.

Step 12: Determine, according to the type of the data operation, whether to initiate a synchronization operation to another DMR.

According to the method of the embodiment, multi-screen real-time synchronization update data can be realized.

A method for data processing according to an embodiment of the present invention is described in detail below with reference to a specific embodiment, including the following steps: Step 101: When the DMS is started, the DMS operation classification table and the DMR operation correspondence table are initialized, wherein the initial record of the DMR operation correspondence table is empty, and the record is added only after the DMR performs the actual operation, and the actual operations may include: Types such as deletion, modification, query, and check judgment; DMS operation classification table initialization includes the types of operations that can be supported on the DMS and the nature of the operation types.

The types of operations that can be supported on the DMS include: types such as: add, delete, modify, query, and check; the nature of the type of operation, that is, whether the operation requires DMS real-time synchronization update.

Table 1 is a DMS operation correspondence table. As shown in Table 1, the DMR records the operation record of a certain data type on the DMS on the DMS. Only when the DMR successfully operates the data on the DMS increases the operation record of the DMR. The operation record of the DMR is added, and when the DMR device is offline, the operation record of the DMR device is deleted.

Table 1

Table 2 shows the operation classification table. The DMS classifies the data services provided by the DMS, records the types of operations that can be performed by the same type of data, and this type of operation requires the DMS to synchronously notify other DMR devices, such as adding, deleting, and modifying. The operation requires DMS real-time synchronization to notify other DMR devices, and the query, check and judgment operations do not require DMS real-time synchronization to notify other DMR devices.

Table 2

Step 102: When the DMR requests a data operation from the DMS, and the DMS checks that it can provide a service to the DMR, the response to the DMR is successful. If the DMR operation request cannot be satisfied, the response to the DMR fails.

Step 103: If the DMS responds successfully to the requested DMR, add an operation record to the DMR operation correspondence table, record the address of the DMR, the data type of the operation, and the operation type.

Step 104: After recording the DMR operation correspondence table, the DMS needs to query its own operation classification table to confirm whether the DMR operation needs to initiate a DMR real-time data synchronization update operation. If the DMR operation is a query and check. Type, you do not need to initiate real-time data synchronization update operation; otherwise, if the DMR operation is an operation such as adding, deleting, modifying, etc., it is necessary to initiate a real-time data synchronization update operation.

Step 105: If a real-time synchronous update operation needs to be initiated, the DMS needs to query the DMR operation correspondence table, query the record with the same data type as the current processing, and find other multi-screen DMR addresses, where the multi-screen DMR refers to multiple terminals or multiple Client

The DMR operation record is recorded in the DMR operation correspondence table, but this operation record may record the user-operated collection data, and may also record the user-played play bookmark record data, and may also record the user operation. Query VOD (Video On Demand) list data. The synchronous update operation is corresponding to the same type of data. For example, if a user operates the play record record data, it needs to notify other users to play the bookmark data and needs to be updated, and if other users have not operated the bookmark data yet, This user notification.

Step 106: The DMS sends an event notification DMR update data according to the queried DMR address;

Step 107: The multi-screen DMR receives the data update notification, and updates the display of the data according to the actual page display.

FIG. 2 is a schematic diagram of a DMS according to an embodiment of the present invention. As shown in FIG. 2, the DMS of this embodiment includes:

a receiving module 21 configured to receive a data operation requested by the digital media receiver; The synchronization processing module 22 is configured to determine whether to initiate a synchronization operation to other digital media receivers based on the type of data operation.

In a preferred embodiment, the DMS further includes:

The recording module 23 is arranged to record the address of the digital media receiver and the type of the data operation in a preset operational correspondence table.

The synchronization processing module is configured to query a preset operation classification table according to the type of the data operation. If the type corresponding to the type of the data operation is queried to be synchronized, the synchronization is initiated to other digital media receivers. Operation, otherwise no synchronization is initiated to other digital media receivers.

The type of the data operation queried by the synchronization processing module is a type of data operation to be synchronized, including: adding, deleting, and modifying.
