A method for configuring data synchronization, as shown in Figure 1:

Step 101, read and analyze the data output by the master-standby multiplexing device in real time, and obtain the configuration data;

The switcher receives in real time the data output by the active/standby multiplexing equipment, that is, the packaged multiplexing stream (PMS, Packetized Multiplexing Stream) code stream, parses the received PMS code stream, and obtains the configuration data of the active/standby multiplexing equipment, wherein the The PMS code stream is a data stream in binary form, including configuration data of active and standby multiplexing devices and other media data, and the configuration data includes network data, service data, and the like.

The PMS stream received by the parsing and obtaining the configuration data of the master/standby multiplexing device comprises: the switcher converts the PMS stream in binary form into multi-frame data according to the CMMB protocol; the multi-frame data is a data stream in a frame format , the number of its data frame is cyclic, and the configuration data is saved in the 0th frame. The conversion to multiframe data includes: in the PMS code stream of every 1 second, the first PMS packet is time data, and then PMS packets containing multiframe description data and a certain number of PMS packets containing data are alternately formed; The multiframe description data includes: the number of PMS packets forming a multiframe, and the certain number is the number of PMS packets in the multiframe description data. According to the multiframe description data, read the valid data in the subsequent PMS packets corresponding to the number of multiframe description data, and then form a multiframe according to the data composition of the multiframe specified by the CMMB protocol, and then read the next multiframe containing The PMS packet describing the data forms the next multiframe, and so on, the PMS code stream is converted into multiframe data, and the valid data in the PMS packet can be read according to the fixed position of the PMS packet specified by the CMMB protocol. Read and save the configuration data in frame 0 of the active/standby multiplexing device.

Step 102, determine the configuration data difference of the active and standby multiplexing devices, and obtain the result of the difference;

The switcher compares the parameter values corresponding to the same parameters in the configuration data of the active and standby multiplexed devices in turn. If the parameter values corresponding to all the parameters of the active and standby multiplexed devices are the same, there is no difference in the configuration data; otherwise, the configuration data of the active and standby multiplexed devices has The difference is to obtain a difference result, and the difference result includes parameters with different parameter values, the parameter values of the standby multiplexing equipment and the parameter values of the active equipment corresponding to the parameters.

Step 103, configure the configuration data of the standby multiplexing device according to the difference result.

The switcher sends the difference result to the standby multiplexing device, and the standby multiplexing device receives the difference result, queries the local configuration data according to the parameters in the difference result, and overwrites the local configuration data with the parameter value of the primary multiplexing device in the difference result, The parameter value for the same parameter as the parameter in the diff result. So far, the configuration data in the active and standby multiplexing devices are consistent. Wherein, the standby multiplexing equipment in the multiplexing equipment can be determined according to the local configuration of the switch.

The configuration analysis module 202 is specifically used to compare the parameter values of the same parameters in the master-standby multiplexing device configuration data, if the parameter values of all parameters are the same, then the master-standby multiplexing device configuration data is the same, and no processing is performed; if any The parameter values of the parameters are different, and the parameters with different parameter values, the parameter values of the active multiplexing equipment and the parameter values of the standby multiplexing equipment corresponding to the parameters, that is, the difference results are sent to the difference synchronization module 203 .
