The accent platform order that described tune command is sent based on the user.
SourceFilter arranges frequency, bandwidth when control CMMB equipment carries out frequency modulation, in order to receive the program of different frequent points;
Step 2, SourceFilter controls CMMB equipment by the driver of CMMB equipment and carries out frequency modulation; After receiving play command, SourceFilter receives the CMMB multiplexed sub frame data that CMMB equipment sends, and exports the multiplexed sub frame data to the CMMB demodulation multiplexer by its output PIN;
SourceFilter carries out the basic procedure of tuning process referring to accompanying drawing 2, comprises the following steps:
The frequency-modulating process of CMMB equipment is prior art, repeats no more herein.
If frequency modulation mistake, direct execution in step 203.Situation about beginning again after for example stopping playing.
Judge whether to begin to play according to Play Control order or broadcast state sign, the Play Control order is to send to the CMMB demodulation multiplexer by upper level applications after the user clicks broadcast button.
After CMMB equipment frequency modulation is complete, if receive the play command that SourceFilter sends, receives the multiplexed sub frame data of network side broadcast transmission, and the multiplexed sub frame data that receive are sent to SourceFilter.SourceFilter carries No. SID in the play command of CMMB equipment transmission, so that CMMB equipment receives broadcast data.
If finish or the user sends and plays the order stop, SourceFilter stops message or judges whether to stop to play according to the broadcast state sign that the upper strata arranges according to what receive.
Step 3, the CMMB demultiplexer receives the multiplexed sub frame data of SourceFilter output PIN output, audio, video data is carried out demultiplexing and separates, the CMMB demodulation multiplexer transfers Audio and Video to audio/video flow from the multiplexed sub frame data, and PIN exports to corresponding decoder by output, uses out for the ESG resolver ESG data separating, after audio/video flow is decoded by decoder, play by display unit, idiographic flow comprises the following steps referring to accompanying drawing 3:
Described Play Control order is to send to the CMMB demodulation multiplexer by upper level applications after the user clicks broadcast button.
Step 302 judges whether to finish, and if so, flow process finishes, otherwise, execution in step 303;
Whether receive the message that broadcast stops or identifying to judge whether to finish by the judgement broadcast state by checking, that is determining whether to play.
Step 303 receives the multiplexed sub frame data that SourceFilter sends;
Step 304 is carried out separating treatment according to the difference of PID to the multiplexed sub frame data, and inhomogeneous data are delivered to respectively corresponding decoder element;
The PID of ESG data, voice data, video data and lteral data is different, therefore can separate Various types of data according to PID, obtains one or more in following data: ESG data, voice data, video data, lteral data.
Step 305 determines whether the ESG data, if so, and execution in step 306, otherwise, execution in step 307;
Data after the ESG resolver will be resolved send display unit to carry out the programme demonstration.
Step 307 determines whether sound, video data, if so, and execution in step 308, otherwise, execution in step 310;
Step 308 is assembled into respectively the Packet Generation of image, sound to corresponding decoder;
During assembling datagram, the CMMB demodulation multiplexer is encapsulated in video data in a plurality of MediaSample, and take out the timestamp of video data from multiplexed sub frame, get to respectively on corresponding video MediaSample, similarly, the CMMB demodulation multiplexer also is encapsulated in voice data in a plurality of MediaSample, and takes out the timestamp of voice data from multiplexed sub frame, gets to respectively on corresponding audio frequency MediaSample.Audio and Video data with identical time stamp will be play simultaneously, to guarantee the synchronous of sound and image.
Step 310 gives other decoders or resolver to process.
Except ESG data, sound, video data, may be also lteral data, send corresponding character decoder to process, the data after character decoder is processed send display unit to show.
SourceFilter is after receiving the ESG data, if find that data are more, for example a certain channel has two programs, and wherein only have a programs to watch for this user, can send the PID filter command to CMMB equipment by driver, make the data that CMMB equipment only sends to be needed when follow-up transmission data, thereby alleviate the load of CMMB equipment.
The ESG resolver receives the ESG data flow of CMMB demodulation multiplexer output.The ESG resolver receives the ESG data, and edge joint is received the limit and resolved, until complete the parsing of whole ESG data, presents at last user interface and shows, changes platform for the user.Its flow process comprises the following steps referring to accompanying drawing 4:
Step 402 is carried out the assembling of ESG data;
The ESG data be assembled into prior art, repeat no more herein.
Step 403 judges whether to harvest the ESG data, if so, and execution in step 404, otherwise, return to step 401;
Step 404 is shown to the interface with the data that assemble, and changes the platform operation for the user.
The present invention uses DirectShow architecture design CMMB Digital Television to play device, comprises from the multiplexed sub frame data of CMMB device drives collection CMMB separating ESG data, audio, video data, lteral data with the use demodulation multiplexer; Resolve the ESG programme; And the method that the decoder that uses image and sound is decoded and Synchronization Control is play.
Should be understood that; concerning the those of ordinary skill in field, the technology of the present invention place; can be equal to accordingly according to technical scheme of the present invention and design thereof and change or replace, and all these changes or replacement, all should belong to the protection range of claims of the present invention.
