Embodiment
For achieving the above object, at the automatic channel conversion method of the broadcasting of upgrading by regular channel, with reference to the accompanying drawings, describe useful embodiment of the present invention in detail with mobile communication terminal.
Fig. 1 is the block diagram that shows the DMB multiplet that comprises in the MCI (MCI:Multiplex Configuration Information).
The multiplet of DMB (DMB:Digital Multimedia Broadcasting), constitutes by service (Service), serviced component (Service Component) order for going up most level structure with ensemble (Ensemble).The broadcasted content physical load that DMB provides is transmitted in a plurality of subchannels (Sub-channel) of main service channel (MSC:MainService Channel).Wherein, ensemble is meant the broadcasting station, and service refers to the kind of broadcast program.And the broadcast program that provides when selecting service is provided serviced component.Fast information channel in dab receiver (FIC:Fast Information Channel) is by MCI, information on services (Service Information, SI), TMC (TMC:Traffic Message Channel) constitutes, MCI comprises information such as the type service, position, form of main service channel, is used for main service channel is resolved.Information on services comprises service caption and channel information, and TMC provides the emergence message data, services.
Fig. 2 a is fast information group (FIG:Fast InformationGroup) transmission frame-form that shows in the digital multimedia broadcasting system.
The FIB (FIB:Fast Information Block) that constitutes fast information channel in dab receiver has a plurality of fast information group in the data field (data field) of 30 bytes (bytes).Each fast information group is made of fast information group head and fast information group data field, in the fast information group head, has separated the snap information set type (type) of 3 bits and the length (Length) of 5 bits.The expansion (extension) that in the fast information group data field, has distributed 3 bits.
Fig. 2 b is the table that shows the formation of the fast information group transmission frame in the digital multimedia broadcasting system.
The snap information set type is used in reference to shows fast information group comprises which kind of information in MCI, information on services and the snap information data channel (FIDC:Fast Information Data Channel).Below, when showing as FIG m/n, m represents the snap information set type, n represents expansion (extension).FIG type 0 datafield provides polynary formation (MCI), basic service information.FIG type 1 data field assigned picture show label (label) and be used for the sign (label) of display message content.FIG type 5 data field definition paging (Paging), TMC, emergency warning system emergence message data channel (FIDC such as (EWS:Emergency Warning System); Fast Information Data Channel).FIG type 6 data field definition is about the control and the management information transmission of the serviced component (Service Component) of process scramble.
Fig. 3 is of the present invention by the regular channel renewal of DMB recipient, and the broadcasting of translated channel constitutes block diagram with the inside of mobile communication terminal automatically.
RF Department of Communication Force 10 receives the ensemble transmission frame signal that comprises multiple service, serviced component.Coded Orthogonal Frequency Division Multiplexing (COFDM) (COFDM) decoder 20 is removed frequency interleave, exports original signal, and frequency interleave makes the mistake of above-mentioned transmission frame on frequency axis of RF Department of Communication Force 10 inputs become randomization, is output as original signal.Service multichannel (Service Multiplexer) detector 40 detects all ensembles in the set frequency range from through the transmission frame of decoding.At this moment, detect ensemble, service, the serviced component of listening to the broadcast program in watching.Channel decoder (Channel Decoder) 50 is decoded into a plurality of subchannels of detected ensemble (Ensemble) by the FIG m/n data of fast information channel in dab receiver (FIC) the transmission line output of going forward side by side.The fast information channel in dab receiver (FIC) that comprises in the transmission frame is resolved maximum 64 subchannels of output and 2
23Service.The multiple service identifier (Service ID) that MCI database 60 is preserved the ensemble of the FIG m/n data of decoding.
Fig. 4 is the automatic channel conversion method flow chart of the broadcasting of passing through regular channel renewal of the embodiment of the invention with mobile communication terminal.
Detect the service identifier (Service ID) of the ensemble configuration information of reception, step S400.Differentiate and detect whether the service identifier of removing is the service identifier of registering in the MCI, step S401.When the service identifier of registering in detected compound identifier and the MCI is same service identifier, do not upgrade, directly receive broadcast program, step S402; The service identifier of preserving in the delete database (DB:Data Base), step S403.When the service identifier of registering in detected service identifier and the MCI is inequality, in the MCI database, register new database more, step S404.At this moment, when subchannel (sub-channel) when change, the subchannel that frequency information is set to change (Sub-channel), by with service identifier (Service ID) the corresponding broadcast channel program receiving of reception, step S405～step S407.When service, when subchannel all changes, with service, the subchannel of change, in same frequency, receive broadcasting, upgrade the channel information database.Press some cycles, upgrade above-mentioned broadcast channel information, be stored in service MCI database, step S408～step S409.The some cycles that upgrades channel information was that unit is provided with 1 minute.Differentiate whole variations of subchannel, serviced component by service identifier.
Beneficial effect of the present invention is that regular update comprises fast information channel in dab receiver (the Fast Information Channel of service identifier (Service ID); FIC) channel information is automatically converted to the frequency band that same ensemble (Ensemble) is provided to channel, makes the user can more safely use the effect of mobile broadcast receive channel.
Above embodiment only is used to implementation process of the present invention is described, is not to be used to limit protection scope of the present invention.
