Abstract
The present invention discloses a multiplexing code stream analysis method suitable for a multiplexer and a device thereof. The device comprises a data acquisition module, a display module and an analytic statistics module. The method comprises the following steps of dispatching a request message for acquiring a multiplexing code stream to the multiplexer, wherein the request message comprises a filtration condition; the multiplexer returning a multiplexing code stream which conforms to the filtration condition; decoding the multiplexing code stream and displaying multiplexing code stream information; selecting a specific multiplexing code stream, analyzing and demonstrating the validity of the multiplexing code stream, and storing the analytic result; dispatching a request message for stopping the acquisition to the multiplexer; and the multiplexer stopping the return of the multiplexing code stream. By using the method and the device, the state of the code steam output of the multiplexer can be monitored in real time, and a statistical analysis also can be carried out in real time for the code stream. The real time ability and the flexibility of the analysis and the analytic statistics ability are improved so that relevant personnel can quickly position a failure. The debugging time and the starting time are saved, and the debugging efficiency and the starting efficiency are improved.

In mobile multimedia broadcast system, multiplexer is in front end, is used for efficiently encapsulating in real time and sending multimedia service.Figure 3 shows that the position of multiplexer, this shows that the effect of multiplexer is very important at the Mobile Multimedia Broadcasting front end system.
In whole multiplex process, have audio coding in the input, video coding, data or the like, and multiplexing output adopts PMS (Packetized Mutiplexing Stream, the multiplexing code stream of packing) bag to carry, the structure of PMS bag is as shown in Figure 4.
In multiplex process, break down when need getting rid of, need the multiplexing code stream of output be extracted and analyze, therefore obtain and analyze the structure of multiplexed frame fast, very necessary to the correctness of the normal operation that guarantees system and interface.
The method of structure of obtaining and analyze multiplexed frame in the prior art is for being to gather by hardware, off-line analysis then, and the defective of this method is that real-time is poor, very flexible, and can not store the multiplexing code stream of appointment; A little less than the function of analytic statistics.
Technical scheme
The technical problem to be solved in the present invention is, a kind of multiplexing code stream analytical method that is applicable to multiplexer is provided, and can obtain the structure of multiplexing code stream fast from multiplexer, improves real-time, flexibility and the analytic statistics ability analyzed.The present invention also provides a kind of multiplexing code stream analytical equipment that is applicable to multiplexer.
The multiplexing code stream analytical method that is applicable to multiplexer among the present invention comprises the steps:
Step S100: send the solicited message of gathering multiplexing code stream to described multiplexer, this solicited message comprises filtercondition;
Step S101: described multiplexer returns the multiplexing code stream that meets described filtercondition;
Step S102: the described multiplexing code stream that meets filtercondition is decoded, and show described multiplexing code stream information;
Step S103: from described decoded multiplexing code stream, select specific multiplexing code stream, the correctness of the described multiplexing code stream of analysis verification, and preserve analysis result;
Step S104: send the request message that stops to gather to described multiplexer;
Step S105: described multiplexer stops to return multiplexing code stream.
Wherein, among the step S100, also comprise acquisition time in the described request information.
Wherein, also comprise among the step S101: judge by described multiplexer whether filtercondition is suitable,, then before returning the multiplexing code stream that meets filtercondition, return a successful respond if suitable; Otherwise, return a failure and reply.
Wherein, among the step S103, preserve analysis result with file or diagrammatic form.
The multiplexing code stream analytical equipment that is applicable to multiplexer of the present invention comprises data acquisition module, display module and analytic statistics module;
Described data acquisition module is used for sending the solicited message of gathering multiplexing code stream to described multiplexer, comprises filtercondition in the described request information; Also be used for the multiplexing code stream that meets filtercondition that the described multiplexer of buffer memory returns, and transmission stops to gather solicited message;
Described display module is used for taking out from described data acquisition module and meets the multiplexing code stream of described filtercondition and described multiplexing code stream is decoded, and shows described multiplexing code stream information;
Described analytic statistics module is used for selecting specific multiplexing code stream from the decoded multiplexing code stream of described display module, the correctness of the described multiplexing code stream of analysis verification, and preserve analysis result.
Beneficial effect of the present invention is, output code flow situation that can the real time monitoring multiplexer, also can carry out statistical analysis to code stream in real time, real-time, flexibility and the analytic statistics ability analyzed have been improved, make related personnel's fault location fast, save debugging and beginning time, improved debugging and beginning efficient.

Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are described in detail.
Fig. 1 is an embodiment schematic diagram of the multiplexing code stream analytical equipment among the present invention.The multiplexing code stream analytical equipment comprises: data acquisition module, display module and analytic statistics module;
Described data acquisition module is used for sending the multiplexing code stream that the described multiplexer of solicited message, buffer memory of gathering multiplexing code stream returns to described multiplexer, and sends when the multiplexing code stream of gathering is much of that and stop to gather solicited message.
Described display module is used for decoding from described acquisition module taking-up multiplexing code stream with to described multiplexing code stream, and shows described multiplexing code stream information, comprises the kind and the summary info of multiplexing code stream;
Described analytic statistics module is used to select specific multiplexing code stream, the correctness of the described multiplexing code stream of analysis verification, and preserve analysis result.
Fig. 2 is the multiplexing code stream collection analysis schematic flow sheet in one embodiment of the present of invention.The flow process of multiplexing code stream collection analysis is:
