Method and system for synchronizing data between IPTV system modules

Abstract

The present invention discloses a method for synchronizing data between IPTV system modules, wherein the method comprises the following steps: updating the record in a dynamic table by a master control module according to the changed dynamic data; transmitting synchronizing information to a service processing module; after the service processing module receives the synchronizing information, updating the record in the internal memory database of service processing module corresponding with the list name and record number carried in the synchronizing information according to operation style carried by the synthesizing information, or the operation style, field changing mark and changing content carried by the synthesizing information, and reverting the answering synchronizing information of master control module. The invention also discloses a system for synchronizing data between IPTV system modules, wherein the system comprises the master control module and the service processing module. The method and the system according to the invention can increase the real-time property of synchronizing and reduces the data volume needing synchronization.

Description

technical field [0001] The invention relates to a data synchronization technology of an internal memory database, in particular to a method and system for data synchronization between modules of an IPTV (Interactive Network Television) system. Background technique [0002] The relevant data of the IPTV system is divided into static data and dynamic data. Among them, static data refers to the data that does not change during the operation of the system; dynamic data refers to the data that changes during the operation of the system. The topological relationship among the background, main control module and service processing module in the IPTV system is as follows: figure 1 As shown, wherein, the background is generally a PC, which is used for configuring and changing the static data, and synchronizing the configured or changed static data to the main control module; the main control module is used for receiving the static data Synchronized to each business processing module...

AI Technical Summary

Problems solved by technology

This method requires a large amount of data to be synchronized, and if this method is used to synchronize the main control module and multiple business processing modules, it is necessary to allocate an out-of-sync queue for each business processing module in the main control module, so as to mark whether It is necessary to synchronize the data to the business processing module and whether the data is successfully synchronized to the business processing module, that is, if there are several business processing modules in the system, several out-of-sync queues need to be allocated, which will take up a lot of memory Space, it can be seen that this method is not suitable for synchronization between the main control module and multiple business processing modules
