Description

A kind of processing method of broadcast data, treatment system and device

Technical field

The present invention relates to communication technical field, particularly relate to a kind of processing method of broadcast data, treatment system and device.

Background technology

Terminal, as a kind of networked communication device be widely used, as mobile terminal, household digital TV set-top box, car-mounted terminal, sector application terminal etc., has penetrated into the various aspects of social life by various product form.

Generally various application program can be installed in the processing module (being called terminal processing module) of terminal, usually these application programs carry out connected network communication by TCP/IP (TransmissionControlProtocol/InternetProtocol, transmission control protocol/Internet Protocol).Such as, mobile terminal can install browser program, music program, video reproduction program, photo browser, games etc.; Car-mounted terminal can install GPS (GlobalPositioningSystem, global positioning system) communication navigation program, digital television program playing program, music program, games etc.

Along with the maturation of digital broadcast technologies, terminal can pass through integrating digital broadcast receiver module, as CMMB (ChinaMobileMultimediaBroadcasting, China Mobile multimedia broadcasting) module, carry out the broadcast data that receiving digital broadcast network provides.Digital broadcast technologies has high bandwidth, real-time, the advantage that can carry all kinds of multi-medium data, and increasing terminal obtains colourful digital information digital broadcast network by integrating digital broadcast receiver module from digital broadcast network.Digital broadcast network can be wired broadcasting network, also can be wireless broadcast network.

Fig. 1 shows the schematic diagram of integrating digital broadcast receiver module in the terminal, as shown in Figure 1, Digital Broadcasting Receiver module is mainly connected with terminal processing module, this Digital Broadcasting Receiver module mainly comprises broadcast data reception unit 101, Data Analysis unit 102 and datagram controller 103, wherein, broadcast data reception unit 101 is mainly used in receiving digital broadcast signal, carries out preliminary treatment to the digital broadcast signal received, and exports broadcast data transmission stream (TS) code stream; Data Analysis unit 102, is mainly used in the TS code stream receiving the output of broadcast data reception unit 101, and obtains multiplexed frame or multiplexed sub frame to TS code stream demultiplexing; Datagram controller 103 mainly provides the interface channel with terminal processing module, Data Analysis unit 102 is processed broadcast data payload transmission to the terminal processing module obtained and carries out playing or showing.

The problem of following two aspects can be there is in actual applications in the terminal processing module being integrated with Digital Broadcasting Receiver module shown in Fig. 1:

One, the application program in terminal processing module can not participate in the process to the broadcast data that Digital Broadcasting Receiver module receives.

Application program, for music program, when obtaining data by ICP/IP protocol networking, is undertaken alternately by the communication pattern of " request/response " and IP communication network.In order to obtain the data in IP network, as certain music file, application program in terminal processing module wants designated tone music file download address, as IP address or URL (Uniform/UniversalResourceLocator, URL(uniform resource locator)) address, initiate music file download request to network side again, the music file download service program in network responds the download request sent by application program, sends music file to application program by the mode of response.And for being integrated with the terminal processing module of Digital Broadcasting Receiver module, music file can be sent to terminal processing module by the mode pushed by radio network, music program is without the need to obtaining music file to the request of radio network initiating communication again.Like this, be existingly representative with music program application program just exists a defect, lack a suitable communication plan and make music program extract the music file received by Digital Broadcasting Receiver module.

The reasons that there is above-mentioned defect is, existing music program adopts the communication pattern of " request/response " of ICP/IP protocol, the address designator of a communication cohesion must be had, as IP address or URL address, the request of ability initiating communication, and " request/response " communication pattern required by ICP/IP protocol architecture do not deferred to by radio network, Digital Broadcasting Receiver module cannot the Base communication ability of ICP/IP protocol directly required by support application program, as mark or assign physical communication address or logic communication address.Further, Digital Broadcasting Receiver module generally has oneself independently CPU (CentralProcessingUnit, central processing unit) and computing environment, receives and process broadcast singal demodulation broadcast data out.Simultaneously, Digital Broadcasting Receiver module is the ancillary equipment of terminal processing module, the broadcast data received can only be forwarded to terminal processing module by the physical interface of peripheral communication and driver thereof, even all understand and whether support ICP/IP protocol less than in terminal processing module, more do not understand the music program whether being provided with and using ICP/IP protocol networking.

Visible, the terminal processing module of above-mentioned integrating digital broadcast receiver module, just play or show the broadcast data that Digital Broadcasting Receiver module receives simply, and the application program do not comprised by terminal processing module participates in the process to digital broadcast data.

Two, terminal processing module can not participate in the process to the broadcast data that Digital Broadcasting Receiver module receives.

For the terminal processing module of integrating digital broadcast receiver module, in order to lifting section electrical efficiency, the average battery consumption of terminal processing module during to reduce receiving broadcast signal as far as possible, at present, with the CMMB demodulator power consumption of radio frequency amplifying circuit and applicable mobile reception between 0.73mW to 1.3mW, and personal hand-held mobile terminal requires to adopt powered battery, and considers heat dissipation problem, power consumption is less than 100mW, just can meet the needs of terminal use.Time slicing techniques is the power-saving technology introduced in mobile digital broadcast, effectively can reduce the average power consumption that mobile terminal receives and processes broadcast singal.

The burst oriented data transmission of transmitting terminal due to broadcast system, intensively sends broadcast data business in each time burst, and this business monopolizes whole bandwidth.The timeslice of receiving terminal at selected business place receives information, and between two timeslices, (i.e. idling cycle) makes energy-efficient treatment, thus effectively reduces receiving terminal average power consumption.Certainly, during this, the transmitter of front end works always, can transmit other business datum between two timeslices of identical services, and broadcast singal is exactly be made up of so many timeslices.From the angle of receiver, the business datum received is not traditional continuous input mode of constant rate of speed, and data in a discrete fashion interval arrive, and are therefore called burst mode transmission.Meanwhile, time slicing techniques provides the mechanism of from TS code stream extraction time parameter information, counts the Delta-T time, and this relative time indicates that current business burst has the relative time of the timeslice of identical services to the next one.Therefore, receiving terminal can be transformed into operating state when next timeslice arrives from power save mode according to this parameter.Time slicing techniques, by being optimized broadcast singal transmission mode, by optimizing the radio frequency amplifying circuit of receiving terminal and the operating state of demodulator, thus reaches the average power consumption reducing receiving terminal and receive and process broadcast singal.

Broadcast system data link layer adopts multiplex/demultiplex technology to carry out transfer of data.The transmitter of front end adopts multiplex technique to carry out digital broadcasting.The multiplexing multiple multiplexed frame of broadcast channel frame, each multiplexed frame is multiplexing multiple multiplexed sub frame again, is filled again form by multiplex frame head, one or more multiplexed sub frame.Each multiplexed sub frame is made up of subframe head, video-frequency band, audio section and data segment again, wherein, comprises again some control informations and retain position in subframe head.Receiving terminal will carry out multiplexing reverse process (i.e. demultiplexing), solves multiplexed sub frame, solve video-frequency band, audio section and data segment from multiplexed sub frame from multiplexed frame.As a rule, video-frequency band and audio section carrying audio frequency and video TV service, data segment carrying digital broadcast service.For convenience of description, follow-up receiving terminal receiving broadcast signal to be called " preprocessing process " to the process exporting TS transport stream, the broadcast singal received is converted to baseband signal and sends demodulator in broadcast data reception unit 101 to by the radio frequency amplifying circuit in broadcast data reception unit 101, demodulator carries out OFDM demodulation system, Veterbi decoding, convolution de-interleaving and RS decoding successively, exports decoded TS code stream afterwards; After preprocessing process, Data Analysis unit 102 carries out demultiplexing processing procedure.

In practical application, in order to meet the requirement of real-time of broadcast data, broadcast data reception module can be carried out preprocessing process by broadcast data reception unit 101 simultaneously and carry out demultiplexing processing procedure by Data Analysis unit 102, and these two processes can only process in a serial fashion respectively in real time, such Problems existing really can not play time division technology to bring potential power savings to terminal processing module.Because: broadcast data reception module is when carrying out preprocessing process, in order to receiving broadcast signal, need to make radio frequency amplifying circuit and demodulator in running order, namely broadcast data reception module is in running order, and time division technology is at performance energy-saving effect, require after preprocessing process terminates, radio frequency amplifying circuit and demodulator are in power save mode., broadcast data reception module also will carry out demultiplexing process, and is carry out in a serial fashion after preprocessing process terminates.This just requires that broadcast data reception module is still in non-energy-conservation operating state.Therefore, time division technology is that broadcast data reception module provides the idling cycle entering power save mode after preprocessing process, but in this idling cycle, because of the restriction of the demultiplexing process that serial is carried out, broadcast data reception module will carry out demultiplexing process, power save mode cannot be entered

In sum, the application program in existing terminal processing module or terminal processing module can not process broadcast data, thus reduces the utilance of terminal processing module in the processing procedure of broadcast data.
