The size of the data that the needs that step 20, STB program are come out according to the controll block information analysis are accepted; Dynamic assignment goes out size of data 1.5-2.5 internal memory doubly from system, is the memory configurations that distributes to accept the reception buffering area of the demultiplexing module of data;
Step 30, write some bytes in the place of the terminal segment distance of the internal memory that obtains from dynamic assignment data as buffer tag;
Step 40, demultiplexing module is set receives all block datas, receiving mode is uninterrupted receiving mode, and before demultiplexing module stops, directly sending into the data that receive in the corresponding buffering area of module;
Step 50, STB program real time monitoring buffer tag if find that buffer tag is rewritten, think that then the data that receive have surpassed the scope that needs reception, then stop the Data Receiving of demultiplexing module through the STB program;
Step 60, the dynamic assignment of STB routine call at this moment function are used for storing final data to be assigned to and will to receive the corresponding internal memory of size of data; Data in the analysis buffers simultaneously after each section data analyzed, are placed on data on the relevant position of internal memory of final storage data; After receiving all section data in buffering areas and all having analyzed, add up and also have which section not to be received, perhaps data are damaged, carry out record to these section numbers, set up one need reception the section segment table;
Step 70, release receive the internal memory of buffering area; The size that the reception buffer of each demultiplexing module is set simultaneously is the size of a section; Being configured to receive section data just stops to receive automatically; And call call back function analysis, the section segment table that receives as required, a plurality of demultiplexing module of parallel starting;
Step 80, etc. the reception of pending data; When receiving data; Analyzing the back inserts it on the relevant position of internal memory of final storage data; Discharge its shared demultiplexing module simultaneously, demultiplexing module is set starts obtaining of the section that describes in the section segment table that the next one is received, all receive up to all data and finish; Be filled on the relevant position of internal memory of final storage data, the data of at this moment finally storing in the internal memory of data are exactly the big data that provide of needed certain function.
Wherein, In the said step 30; The place that is used to write buffer tag is greater than more than 1 times and less than 70% the place of removing remaining space beyond 1 times of space of reception size of data, prevents that the buffer tag position from excessively before causing the data of reception incomplete, after the buffer tag position; Owing to certification mark is destroyed the time delays of closing between the demultiplexing module, cause the data of reception to overflow whole buffering area and cause destruction to the STB program.
The present invention has following advantage: this mode has been utilized data use wheel broadcast mode broadcast in DVB (DVB) transfer of data, the characteristics that homogeneous data general continuous of the same race is play, and the principle of having used waterfall to receive receives the overwhelming majority's data.Signal can not be interfered when maximum conditions and in the process of the data of reception, in the time of at this moment can realizing receiving data and surpass buffer tag, reception be exactly whole data, only need to analyze, filling can obtain desired final data.In the ordinary course of things, the process signal of transmission might be interfered, and causes when receiving data above buffer tag; Some data is not received; The 1.5-2.5 that the perhaps situation of corrupted data, the buffering area that is provided with among the present invention are generally real data doubly lets receive data repeatability is arranged exactly; Guarantee can reduce as far as possible that twinkling signal disturbs and the data that cause are not received, perhaps the situation of corrupted data.Even finally data are not received or along bad, used parallel mode to carry out special reception according to the data of data of not receiving or damage more in addition, reached the purpose of complete reception data.
