Embodiment
Basic thought of the present invention is: read the data and the parsing of active and standby multiplexing equipment output in real time, obtain configuration data, determine configured data difference, obtain difference results, dispose the configuration data of standby multiplexing equipment according to difference results.
The present invention is described in detail below by accompanying drawing and specific embodiment.
The method that a kind of configuration data is synchronous, as shown in Figure 1:
Switch receives the data of active and standby multiplexing equipment output in real time, i.e. Da Bao multiplex stream (PMS, Packetized Mutiplexing Stream) code stream, resolve the PMS code stream that receives, obtain the configuration data of active and standby multiplexing equipment, wherein, described PMS code stream is the data flow of binary form, comprise the configuration data of active and standby multiplexing equipment and other media data etc., described configuration data comprises network data, business datum etc.
The PMS code stream that described parsing receives, the configuration data that obtains active and standby multiplexing equipment comprises: switch converts the multi-frame data to according to the PMS code stream of CMMB agreement with binary form; Described multi-frame data are data flow of frame format, and the numbering of its Frame circulates, and preserve configuration data in the 0th frame.The described multi-frame data that are converted to comprise: in the PMS code stream in per 1 second, first PMS bag is time data, is that the PMS bag that comprises the multi-frame data of description is formed with the PMS packet interleaving that comprises data of some then; Described multi-frame data of description comprises: form the quantity of the PMS bag of a multi-frame, described some is the quantity of the PMS bag in the multi-frame data of description.According to the multi-frame data of description, read the valid data in the PMS bag follow-up and multi-frame data of description respective numbers, form according to the data of the multi-frame of CMMB agreement regulation then, form a multi-frame, read the PMS bag that the next one comprises the multi-frame data of description then, form next multi-frame, and the like, the PMS code stream is converted to the multi-frame data, and read the fixed position that the valid data in the described PMS bag can wrap according to the PMS of CMMB agreement regulation.Read the configuration data in 0 frame of active and standby multiplexing equipment and preserve.
