Description

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

Technical field

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

Background technology

Terminal as portable terminal, household digital TV set-top box, car-mounted terminal, sector application terminal etc., has been penetrated into aspect of social life by various product form as a kind of networked communication device that is widely used.

The processing module of terminal generally can be installed various application programs in (being called terminal processing module), usually these application programs can be passed through TCP/IP (Transmission Control Protocol/Internet Protocol, transmission control protocol/internet interconnection protocol) and carry out connected network communication.For example, portable terminal can be installed browser program, music program, video reproduction program, photo browser, games etc.; Car-mounted terminal can be installed GPS (Global Positioning System, global positioning system) communication navigation program, digital television program playing program, music program, games etc.

Along with the maturation of digital broadcasting technology, terminal can be passed through integrated digital broadcast reception module, as CMMB (China Mobile Multimedia Broadcasting, China Mobile multimedia broadcasting) module, the broadcasting data of coming the receiving digital broadcast network to provide.The digital broadcasting technology has high bandwidth, real-time, the advantage that can carry all kinds of multi-medium datas, and increasing terminal is obtained colourful digital information the digital broadcast network by integrated digital broadcast reception module from digital broadcast network.Digital broadcast network can be the wired broadcasting network, also can be wireless broadcast network.

Fig. 1 shows the schematic diagram of integrated digital broadcast reception module in terminal, as shown in Figure 1, the digital broadcasting receiver module mainly is connected with terminal processing module, this digital broadcasting receiver module mainly comprises broadcasting data receiving element 101, data resolution unit 102 and datagram controller 103, wherein, broadcasting data receiving element 101 is mainly used in receiving digital broadcast signal, and the digital broadcast signal that receives is carried out preliminary treatment, output broadcast data transmission stream (TS) code stream; Data resolution unit 102 is mainly used in receiving the TS code stream that broadcasting data receiving element 101 is exported, and TS code stream demultiplexing is obtained multiplexed frame or multiplexed sub frame; Datagram controller 103 mainly provides the interface channel with terminal processing module, data resolution unit 102 is handled the broadcasting payload user data that obtains transfer to terminal processing module and play or show.

Can there be the problem of following two aspects in actual applications in the terminal processing module of integrated digital broadcasting receiver module shown in Figure 1:

One, the application program in the terminal processing module can not participate in the processing to the broadcasting data of digital broadcast reception module reception.

Application program is example with the music program, when obtaining data by ICP/IP protocol networking, is that communication pattern and the IP communication network by " asking/reply " carries out alternately.In order to obtain the data in the IP network, as certain music file, application program in the terminal processing module is wanted designated tone music file download address, as IP address or URL (Uniform/Universal Resource Locator, URL(uniform resource locator)) address, initiate the music file download request to network side again, the download request that the music file download service program response in the network is sent by application program sends music file to application program by the mode of replying.And for the integrated terminal processing module of digital broadcasting receiver module, radio network can be sent to terminal processing module with music file by the mode that pushes, and the music program need not to initiate communication request to radio network again and obtains music file.Like this, existing is that the application program of representative just exists a defective with the music program, lacks a suitable communication plan and makes music program can extract the music file that is received by the digital broadcasting receiver module.

Exist an aspect reason of above-mentioned defective to be, existing music program adopts the communication pattern of ICP/IP protocol " asking/reply ", the address designator that a communication cohesion must be arranged, as IP address or URL address, could initiate communication request, and radio network is not deferred to ICP/IP protocol architecture desired " asking/reply " communication pattern, the digital broadcasting receiver module is the basic communication capacity of the desired ICP/IP protocol of support application program directly, as sign or appointment physical communication address or logic communication address.Further, the digital broadcasting receiver module generally has own independent CPUs (Central Processing Unit, central processing unit) and computing environment, receives and handle the broadcasting data that the broadcast singal demodulation is come out.Simultaneously, the digital broadcasting receiver module is the ancillary equipment of terminal processing module, can only transmit the broadcasting data of receiving to terminal processing module by physical interface and the driver thereof of peripheral communication, even all understand less than whether supporting ICP/IP protocol in the terminal processing module, more do not understand whether the music program that uses the ICP/IP protocol networking is installed.

As seen, the broadcasting data of digital broadcasting receiver module reception are just play or show to the terminal processing module of above-mentioned integrated digital broadcast reception module simply, and can not participate in the processing to digital broadcast data by the application program that comprises in the terminal processing module.

Two, terminal processing module can not participate in the processing to the broadcasting data of digital broadcast reception module reception.

Terminal processing module for integrated digital broadcast reception module, in order to promote electric-saving efficiency, the average battery consumption of terminal processing module when reducing receiving broadcast signal as far as possible, at present, have radio frequency amplifying circuit and be fit to the mobile CMMB demodulator power consumption that receives about between the 0.73mW to 1.3mW, and the personal hand-held portable terminal requires to adopt powered battery, and consider heat dissipation problem, power consumption is less than 100mW, just can satisfy terminal use's needs.Time slicing techniques is the power-saving technology of introducing in the mobile digital broadcast, can reduce the average power consumption that portable terminal received and handled broadcast singal effectively.

Because the transmitting terminal of broadcast system transmits with the burst type data, the concentrated area sends the broadcasting data service in each burst time, and this business is monopolized whole bandwidth.Receiving terminal receives information in the timeslice at selected professional place, and (being idling cycle) makes energy-efficient treatment between two timeslices, thereby reduces the receiving terminal average power consumption effectively.Certainly, transmitter of front end is worked always during this, can transmit other business datum between two timeslices of identical services, and broadcast singal is exactly to be made up of so many timeslices.From the angle of receiver, the business datum that receives not is to be traditional continuous input mode of constant rate of speed, and data arrive at interval in discrete mode, therefore is called burst and transmits.Simultaneously, time slicing techniques provides the mechanism of from TS code stream extraction time parameter information, counts the Delta-T time, and this relative time has pointed out that the current business burst is to next relative time with timeslice of identical services.Therefore, receiving terminal can be transformed into operating state from power save mode according to this parameter when next timeslice arrives.Time slicing techniques by the radio frequency amplifying circuit of optimization receiving terminal and the operating state of demodulator, reduces average power consumption that receiving terminal received and handled broadcast singal thereby reach by the broadcast singal transmission mode is optimized.

The broadcast system data link layer adopts the multiplex/demultiplex technology to carry out transfer of data.The transmitter of front end adopts multiplex technique to carry out digital broadcasting.The multiplexing a plurality of multiplexed frames of broadcast channel frame, each multiplexed frame is multiplexing a plurality of multiplexed sub frame again, is filled by multiplex frame head, one or more multiplexed sub frame again and forms.Each multiplexed sub frame is made up of subframe head, video-frequency band, audio section and data segment again, wherein, comprises some control informations again and keep the position in the subframe head.Receiving terminal will carry out multiplexing reverse process (being demultiplexing), solves multiplexed sub frame from multiplexed frame, solves video-frequency band, audio section and data segment from multiplexed sub 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 the receiving terminal receiving broadcast signal is called " preprocessing process " to the process of output TS transport stream, radio frequency amplifying circuit in the broadcasting data receiving element 101 converts the broadcast singal that receives to baseband signal and sends the demodulator of broadcasting in the data receiving element 101 to, demodulator carries out OFDM rectification, Veterbi decoding, convolution de-interleaving and RS decoding successively, exports decoded TS code stream afterwards; After the preprocessing process, data resolution unit 102 is carried out the demultiplexing processing procedure.

In the practical application, in order to satisfy the real-time requirement of broadcasting data, the broadcasting data reception module can carry out preprocessing process and carry out the demultiplexing processing procedure by data resolution unit 102 by broadcasting data receiving element 101 simultaneously, and these two processes can only be handled respectively in real time in the mode of serial, and the problem of Cun Zaiing is can not really bring into play the time cutting techniques to bring potential power savings to terminal processing module like this.Because: the broadcasting data reception module is when carrying out preprocessing process, for receiving broadcast signal, need make radio frequency amplifying circuit and demodulator in running order, it is in running order namely to broadcast data reception module, and the time cutting techniques is at the performance energy-saving effect, requirement is after preprocessing process finishes, and radio frequency amplifying circuit and demodulator are in power save mode., the broadcasting data reception module also will carry out demultiplexing to be handled, and is to finish the back at preprocessing process to carry out in the mode of serial.This just requires to broadcast data reception module and still is in non-energy-conservation operating state.Therefore, the time cutting techniques provides an idling cycle that enters power save mode for the broadcasting data reception module after preprocessing process, but in this idling cycle, the restriction of the demultiplexing process of carrying out because of serial, the broadcasting data reception module will carry out demultiplexing to be handled, can't enter power save mode

In sum, the application program in existing terminal processing module or the terminal processing module can not be handled the broadcasting data, thereby has reduced the utilance of terminal processing module in the processing procedure of broadcasting data.
