Figure 10 is exemplified with the exemplary change of protocol version in the time using FIC piece grammer and protocol version structure according to the embodiment of the present invention.
Structure shown in Figure 10 comprises 2 assemblages (, assemblage 0 and assemblage 1)., send two mobile services by assemblage 0 herein, and send a mobile service by assemblage 1.At this moment,, in the time that the secondary protocol version of FIC piece changes, the value of FIC_minor_protocol_version field increases, and indicates this increase.And, respectively the FIC_chunk_header_extension_length field by FIC piece header, ensemble_loop_header_extension_length field, M/H_service_loop_extension_length field with signal indication by extended byte, the extended byte of assemblage circulation header and the extended byte of the mobile service circulation length information separately of the corresponding FIC piece header that secondary protocol version was increased.More particularly, represent each length information with signal, make the traditional receiver that can not continue to use corresponding secondary protocol version change can skip corresponding extended byte.
In the situation of Figure 10, the value of the FIC_minor_protocol_version field of FIC piece changes to " 001 " from " 000 ".And, FIC_chunk_header_extension_length field, ensemble_loop_header_extension_length field and M/H_service_loop_extension_length field are added to (or additional) FIC piece header to the secondary protocol version changing.Now, in the time of 1 byte of FIC piece header extension, FIC_chunk_header_extension_length field is marked as " 001 ".In this case, the extended field of 1 byte (, FIC_Chunk_header_extension_bytes field) is added into the end of FIC piece header.And traditional receiver is skipped the extended field of 1 byte at the end place that is increased in FIC piece header, and does not process corresponding extended field.
In addition,, in the time of 2 bytes of assemblage circulation header extension in FIC piece, FIC_chunk_header_extension_length field is marked as " 010 ".In this case, the extended field of 2 bytes (, Ensemble_loop_header_extension_bytes field) is added into respectively to the end of assemblage 0 circulation header and the end of assemblage 1 circulation header.And traditional receiver is skipped the extended field of 2 bytes that are increased in respectively the end place of assemblage 0 circulation header and the end place of assemblage 1 circulation header, and do not process the extended field of 2 corresponding bytes.
In addition,, in the time of 1 byte of mobile service cyclic extensions of FIC piece, M/H_service_loop_extension_length field is marked as " 001 ".In this case, the end place of 1 the mobile service circulation that the extended field of 1 byte (, M/H_service_loop_extension_bytes field) is added into respectively to the end place of 2 mobile service circulations that send in cycles by assemblage 0 and send in cycles by assemblage 1.And, traditional receiver is skipped the extended field of 1 byte at the end place of 1 the mobile service circulation that is added into respectively the end place of 2 mobile service circulations that send in cycles by assemblage 0 and send in cycles by assemblage 1, and does not process the extended field of 1 corresponding byte.
Figure 11 is exemplified with the example process of processing FIC piece in the time that the secondary protocol version information of FIC piece as shown in figure 10 changes.In the time of FIC_minor_protocol_version field change, the receiver of tradition (or, routine) (receiver that, can not change along the secondary protocol version being used in corresponding FIC piece) is processed the field separating from extended field.Thereafter, traditional receiver uses FIC_chunk_header_extension_length field, ensemble_loop_header_extension_length field, M/H_service_loop_extension_length field, to skip corresponding extended field, and do not process corresponding field.In the time using the receiving system of corresponding secondary protocol version change that can continue to use FIC piece, each length field is for the treatment of even corresponding extended field.
Figure 12 is exemplified with according to the example syntax structure of the FIC piece payload of an embodiment of the invention.For each assemblage corresponding with num_ensembles field in the FIC piece header of Fig. 9, FIC piece payload comprises the configuration information of each assemblage and the information about the mobile service sending by each assemblage.FIC piece payload comprises the mobile service circulation under assemblage circulation and the circulation of this assemblage.(or expectation) mobile service that FIC piece payload can be determined receiver by which assemblage to send request.(carrying out this processing by the mapping between ensemble_id field and M/H_service_id field).Thereby receiver can receive the RS frame of the assemblage that belongs to corresponding.
For this reason, the assemblage circulation of FIC piece payload can comprise ensemble_id field, ensemble_structure_major_version field, ensemble_structure_minor_version field, SLT_ensemble_indicator field, GAT_ensemble_indicator field, M/H_service_configuration_version field and num_M/H_services field, and they repeat number of times many as num_ensembles field value jointly.Mobile service circulation can comprise multi_ensemble_service field, M/H_service_status field and SP_indicator field, and they repeat number of times many as num_M/H_services field value jointly.
Ensemble_id field is corresponding to 8 bit unsigned integer fields, and it indicates unique identifier of corresponding assemblage.For example, value in, can be to ensemble_id field distribution " 0x00 " to the scope of " 0x7F ".Ensemble_id field is carried out in groups (or associated) by mobile service with each assemblage.Herein, preferably, the parade_id field of carrying (or send) by TPC data obtains the value of ensemble_id field.If send corresponding assemblage by main RS frame, highest significant position is set to " 0 ", and remaining low order is used as to the parade_id field value of corresponding queue.Meanwhile, if send corresponding assemblage by auxiliary RS frame, highest significant position is set to " 0 ", and remaining low order is used as to the parade_id field value of corresponding queue.
Ensemble_major_protocol_version field is corresponding to 2 bit unsigned integer fields, and it represents the other version of main (corresponding RS frame structure and mobile service structure particularly) of corresponding assemblage structure.Herein, the change of master agreement version is by the change of the non-back compatible rank of instruction.
Ensemble_minor_protocol_version field is corresponding to 3 bit unsigned integer fields, and it represents the secondary version (each RS frame structure and each M/H traffic signaling channel particularly) of corresponding assemblage structure.Suppose that main release level remains unchanged, the change of secondary protocol version rank is by the change of instruction back compatible rank.Can from FIC piece payload, omit ensemble_structure_major_version field and ensemble_structure_minor_version field herein.
SLT_ensemble_indicator field, corresponding to 1 bit indicator, wherein, in the time being set to " 1 ", will be indicated bearer service label list (SLT) in the M/H of corresponding assemblage traffic signaling channel.
GAT_ensemble_indicator field, corresponding to 1 bit indicator, wherein, in the time being set to " 1 ", is carried instruction of guide access list (GAT) in the signaling flow of corresponding assemblage.
M/H_service_configuration_version field is corresponding to 5 bit fields, and it indicates the version number of each M/H traffic signaling channel of corresponding M/H assemblage.The value of M/H_service_configuration_version field is " to 32 deliverys ", and when any table carrying in the M/H of corresponding assemblage traffic signaling channel changes, the value of this field is taking 1 as incremented (or increase).
Num_M/H_services field is corresponding to 8 bit unsigned integer fields, and it represents the quantity of the M/H business of carrying by corresponding M/H assemblage.For example, in the time that the secondary protocol version of FIC piece changes, and if extended field is added into assemblage circulation header, after num_M/H_services field, increase extended field.
For example, in the time that the secondary protocol version in FIC piece header changes, and in the time extended field being added into assemblage circulation header, after extended field is increased in and follows num_M/H_services field closely.According to another implementation of the invention, if num_M/H_services field is included in mobile service circulation, after the extended field that will increase in assemblage circulation header being increased in and following M/H_service_configuration_version field closely.
The M/H_service_id field of mobile service circulation is corresponding to 16 bit unsigned integer fields, and it identifies corresponding M/H business.The value of M/H_service_id field (or, number) be unique moving in (M/H) broadcast.In the time that M/H business has composition in multiple M/H assemblages, the set of the IP stream corresponding with business in each assemblage is the independent business being regarded as for signaling, exception be that the entry for corresponding business all has identical M/H_service_id field value in FIC.Thereby identical M/H_service_id field value can appear in more than one num_ensembles circulation.And therefore, M/H_service_id field value will represent all business of combination, thereby keeps the uniqueness of M/H_service_id field value.
The field that multi_ensemble_service field is calculated corresponding to 2 bits, whether its identification carries corresponding M/H business by more than one M/H assemblage.And whether the identification of multi_ensemble_service field only uses a part of M/H business of carrying by corresponding M/H assemblage on purpose to express M/H business.
M/H_service_status field is corresponding to 2 bit enumerated field, and it identifies the state of corresponding M/H business.For example, the highest significant position of M/H_service_status field indicate corresponding M/H business be activate (in the time being set to " 1 ") or nonactivated (in the time being set to " 0 ").In addition, least significant bit indicates whether corresponding M/H business is (in the time being set to " 1 ") or not hiding (in the time being set to " 0 ") of hiding.SP_indicator field is corresponding to 1 bit field, and wherein, in the time being set to " 1 ", whether its indicating services protection is applied to the M/H business that provides corresponding important presents at least one required composition.
For example,, in the time that the secondary protocol version of FIC piece changes, and if extended field is added into mobile service circulation, after extended field being added into SP_indicator field.
And FIC piece payload can comprise FIC_chunk_tuffing () field.In order to make the border of FIC piece and to keep aliging at last the FIC section boundary belonging among the FIC section of FIC piece, the filling (stuffing) of FIC_chunk_stuffing () field may reside in FIC piece.Determine the length of filling by remaining how many spaces resolve whole FIC piece payload before filling after.
Now, as shown in figure 13, FIC piece is divided into multiple FIC sections by transmitting system (not shown) according to the present invention, thereby export the FIC section of division to receiving system taking FIC section as unit.The size of each FIC section is 37 bytes, and each FIC section comprises the FIC section header of 2 bytes and the FIC section payload of 35 bytes.More particularly, as shown in Figure 13 (a), FIC piece comprises FIC piece header and FIC piece payload, as shown in Figure 13 (b), taking 35 bytes as unit, FIC piece is carried out to segmentation.And, as shown in Figure 13 (c), FIC section is configured to increase at each section of 35 byte unit to the FIC section header of 2 bytes above.
According to an embodiment of the invention, the length of FIC piece payload is variable.Herein, the quantity and the quantity that is included in the mobile service in each assemblage of the assemblage sending by corresponding used physical transmission channel is depended in the variation of the length of FIC piece.
And FIC piece payload can comprise padding data.In this case, according to the embodiment of the present invention, padding data is aimed at for FIC piece with at last the FIC section boundary belonging among the FIC section of FIC piece.Therefore,, by the length of padding data is minimized, can reduce the unnecessary waste of FIC section.
Herein, by utilizing following equation 1 can calculate the quantity of the padding data inserting in FIC piece.
equation 1
Quantity=the 35-j of padding data byte
J=(5+ is inserted in the quantity of the signaling data byte in FIC piece payload) is to 35 deliverys
For example, in the time that the header of 5 bytes that increase in FIC piece and the total length that is inserted in the signaling data of the payload in FIC piece equal 205 byte, because j equals 30 in equation 1, so the payload of FIC piece can comprise the padding data of 5 bytes.And, comprise that the length of the FIC piece payload of padding data equals 210 bytes., FIC piece be divided into 6 FIC sections, then by its transmission thereafter.Segment number is sequentially distributed to each section of 6 FIC sections of dividing from FIC piece herein.
In addition, as shown in figure 14, the present invention can be sent to single subframe by the FIC section of dividing from single FIC piece, or the FIC section of division can be sent to multiple subframes.If multiple subframes are divided and be sent to situation below as shown in figure 14 by FIC piece like that, even in the time that the quantity of the data that send by FIC piece is greater than the quantity of the FIC section sending by single subframe (this situation is corresponding in the time carrying out multiple business with low-down bit rate), required signaling data can all send by FIC piece.
Figure 14 is exemplified with in the time that the TNoG of corresponding mobile broadcast equals " 6 ", an example of the data of the FIC piece sending by 4 FIC sections.
More particularly, Figure 14 shows an example of the FIC piece that has repeatedly been sent twice.With reference to Figure 14, all FIC sections of dividing from FIC piece send by 2 subframes (subframe 1 and subframe 2), and all FIC sections of dividing from FIC piece only send by one (subframe 1) of 2 subframes.More particularly, the present invention points out to send multiple FIC pieces by single subframe.In Figure 14, the content of 2 FIC pieces can be mutually the same or can be differed from one another.
Herein, in Figure 14, the number table of indicated FIC section is shown in the numbering of the FIC section in each FIC piece, is not the FIC segment number in each subframe.Thereby, can eliminate the subordinate relation between FIC piece and subframe, thereby reduce the excessive waste of FIC section.
In addition, the present invention can increase empty FIC section.No matter the transmission of the repetition of FIC piece, and in the time needing to fill, process remaining FIC section by empty FIC section in corresponding M/H frame.For example, suppose that TNoG equals " 3 " and FIC piece is divided into 2 FIC sections.In the time repeatedly sending FIC piece by 5 subframes in single M/H frame, for example, only send two FIC sections by the subframe (, being positioned at the subframe of last tagmeme with time sequencing) in 5 subframes herein.In this case, an empty FIC section is distributed to corresponding subframe, thereby send.More particularly, this sky FIC section is for aiming at the border of the border of FIC piece and M/H frame.Now, because empty FIC section is not the FIC section of dividing from FIC piece, so FIC segment number is not distributed to sky FIC section.
In the present invention, in the time that single FIC piece is divided into multiple FIC section, and the FIC section after dividing is included in each data group of at least one subframe in M/H frame when transmitting, FIC section corresponding to contrary order-assigned starting with the last subframe in the M/H frame from corresponding.According to the embodiment of the present invention, if there is empty FIC section, empty FIC section is arranged in the subframe of M/H frame, sends so corresponding empty FIC section can be used as last (or final) section.
Figure 15 is exemplified with an example that sends the data of FIC piece in the time that the TNoG of corresponding mobile broadcast equals " 6 " by 8 FIC sections.In this case, the data volume sending by FIC piece is greater than the quantity of the FIC section sending by single subframe.As shown in figure 15, owing to sending the FIC section of dividing from FIC piece by 2 subframes, can send all required signaling datas by single FIC piece herein.And, in this case, distribute to the numbering of each FIC section corresponding to the numbering that is included in each FIC section in FIC piece.More particularly, even in the time that the quantity of FIC blocks of data is greater than the quantity of the FIC segment data sending by single subframe, all FIC blocks of data also can be sent out and do not stay any do not send data division.
At this moment, do not need to process corresponding empty FIC section in order to make receiving system can abandon sky FIC section, need to identify the identifying information of (or differentiation) empty FIC section.
According to one embodiment of the present invention, the present invention uses FIC_type field in the header of empty FIC section as the identifying information for identifying empty FIC section.In this embodiment, the value of the FIC_type field in empty FIC section header is set to " 11 ", to identify corresponding empty FIC section.More particularly, in the time that the value of the FIC_type field in empty FIC section header is set to " 11 " and is sent to receiving system, receiving system can abandon FIC_type field value and be set to the payload of the FIC section of " 11 ", and does not need to process corresponding FIC section payload.Herein, value " 11 " is only the exemplary value that provides to promote and simplify understanding of the present invention.As long as set up pre-configured between receiving system and transmitting system, can specify any value that can identify empty FIC section to FIC_type field.Therefore the example collection that, the present invention is not only limited to represent in specification.In addition, also can indicate the identifying information that can identify empty FIC section by another field in FIC section header.
Figure 16 is exemplified with according to the example syntax structure of the FIC section header of an embodiment of the invention.Herein, FIC section header can comprise FIC_type field, error_indicator field, FIC_segment_num field and FIC_last_segment_num field.Each field will be described below.
FIC_type field, corresponding to 2 bit fields, in the time being set to " 00 ", indicates corresponding FIC section to carry a part of FIC piece.Alternatively, in the time that FIC_type field is set to " 11 ", it is the empty FIC section that sends padding data that FIC_type field is indicated corresponding FIC section.Herein, its residual value is that use in the future retains.
Whether error_indicator field, corresponding to 1 bit field, there is mistake between its instruction transmission period in corresponding FIC section.Herein, in the time there is mistake, error_indicator field is set to " 1 ".And in the time not there is not (or not occurring) mistake, error_indicator field is set to " 0 ".More particularly, during the processing of configuration FIC section, in the time there is the mistake of not repairing, error_indicator field is set to " 1 ".More particularly, error_indicator field makes receiving system can be identified in existence or the appearance of the mistake in corresponding FIC section.
FIC_segment_num field is corresponding to 4 bit unsigned integer fields, and it indicates the numbering of corresponding FIC section.For example, if corresponding FIC section is first FIC section of FIC piece, the value of FIC_segment_num field will be set as " 0x0 ".In addition, if corresponding FIC section is second FIC section of FIC piece, the value of FIC_segment_num field will be set as " 0x1 ".More particularly, FIC_segment_num field by each the additional FIC section along with in FIC piece taking one as incremented.Herein, if FIC piece is divided into 4 FIC sections, the FIC_segment_num field value of last the FIC section in FIC piece will be indicated as " 0x3 ".
FIC_last_segment_num field is corresponding to 4 bit unsigned integer fields, and it indicates the numbering of last the FIC section (, having the FIC section of the highest FIC_segment_num field value) in complete FIC piece.
In traditional method, sequentially specify (or distribution) FIC segment number for each FIC section in a subframe.Therefore, in this case, the numbering of last FIC section always match with TNoG (, the numbering of last FIC section always equals TNoG).But in the time using according to FIC numbering distribution method of the present invention, the numbering of last FIC section does not always match with TNoG.More particularly, the numbering of last FIC section can match with TNoG, or the numbering of last FIC section can not match with TNoG.TNoG represents to distribute (or appointment) sum to the data group of single subframe.For example, in the time that TNoG equals " 6 ", and in the time that FIC piece is divided into 8 FIC sections, TNoG equals " 6 ", and last FIC segment number is " 8 ".
According to another embodiment of the present invention, can be by utilizing the value of the FIC_segment_num field in FIC section header to identify empty FIC section.More particularly, owing to empty FIC section not being distributed to FIC segment number, transmitting system is the FIC_segment_num field value to empty FIC section by empty data allocations, and receiving system can allow to make sky data allocations to the FIC section of FIC_segment_num field value to be identified as sky FIC section.Herein, the data allocations that receiving system and transmitting system can be set in advance, to FIC_segment_num field value, replaces empty data.
As mentioned above, FIC piece is divided into multiple FIC sections, thereby sends or send by multiple subframes by single subframe.And, can send the FIC section of dividing from single FIC piece by single subframe, or can send the FIC section of dividing from multiple independent FIC pieces by single subframe.Now, the numbering that is dispensed to each FIC section is corresponding with the numbering (, FIC_seg_number value) in corresponding FIC piece, and not corresponding with the numbering in corresponding subframe.And, can send empty FIC section and aim at the border of the border to M/H frame and FIC piece.Now, FIC segment number is not dispensed to sky FIC section.
As mentioned above, can send a FIC piece by multiple subframes, or send multiple FIC pieces by single subframe.But, according to the embodiment of the present invention, taking subframe as unit, FIC section is interweaved and sent.
Figure 17 exemplified with as shown at Figure 13 to Figure 15 in the time sending single FIC piece by multiple subframes or in the time sending multiple FIC piece by single subframe, receive and recover an example of the receiving system of one or more FIC piece.
More particularly, collect the FIC data for the signaling information region in the data group of each subframe according to the signaling decoder 118 of receiving system of the present invention, to collected data are interweaved taking subframe as unit.Thereafter, signaling decoder 118 carries out RS decoding to the FIC section of deinterleaving, thereby will export FIC processor 121 to through the data of RS decoding.The FIC segment buffer of FIC processor 121 is stored the FIC section through RS decoding temporarily, then exports the FIC section of storage temporarily to FIC section resolver.FIC section resolver extracts and analyzes FIC section header.Subsequently, based on the result of analyzing, FIC section resolver is collected the FIC section that forms single FIC piece.Thereafter, FIC section resolver removes the FIC section header of (or abandoning) collected FIC section, thereby recovers (or formation) single FIC piece.
For example, FIC section resolver utilizes FIC_segment_num field and FIC_last_segment_num field in FIC section header to collect the FIC section that forms a FIC piece.Then export the FIC piece of recovery to FIC piece resolver.FIC piece resolver extracts and analyzes the header of the FIC piece being transfused to.Then,, based on the result of analyzing, FIC piece resolver extracts the signaling data in the payload that is included in corresponding FIC piece, thereby exports the signaling data of extraction to Service Manager 122.
More particularly, FIC section resolver extracts and analyzes the header that is cushioned the FIC section being then transfused to.Thereafter FIC section resolver search, (or location) FIC_segment_num field value is the FIC section (, comprising the FIC section of first byte of FIC blocks of data) of " 0 ".Once FIC section resolver has been located first FIC section of FIC piece, FIC section resolver is sequentially collected from first FIC section and is started to the data of FIC section with identical FIC_segment_num field value and FIC_last_segment_num field value.Thereafter, FIC section resolver removes the FIC section header of collected FIC section, to form FIC piece, thereby exports the FIC piece of formation to FIC piece resolver.
For example, as shown in figure 17, suppose that the TNoG of corresponding mobile broadcast equals " 6 ", and FIC piece is divided into 5 FIC sections to transmit.With reference to Figure 17, or transmit the FIC section of a FIC piece by 2 subframes, or the FIC section of 2 FIC pieces is sent to a subframe.But, be apparent that, carry out deinterleaving processing taking subframe as unit.And it is 5 FIC sections of the FIC section of " 4 " that the FIC section that collection is " 0 " from FIC_segment_num field value starts to FIC_segment_num field value.,, in the time removing the FIC section header of each FIC section, recovered a FIC piece thereafter.More particularly, in the time having collected the payload of all 5 FIC sections, the FIC piece that recovered (or form).Now, identified empty FIC section by the FIC_type field in corresponding empty FIC section header.But empty FIC section is dropped, and does not use in FIC piece Recovery processing.
Figure 18 is exemplified with in the time transmitting FIC piece by 8 FIC sections, and in the time that the TNoG of corresponding mobile broadcast equals " 6 ", receiving system receives FIC section to recover an example of FIC piece.
And, in Figure 18, although transmit the FIC section of a FIC piece by 2 subframes, be apparent that, carry out deinterleaving processing taking subframe as unit.Because the FIC piece Recovery processing of Figure 18 is identical with the FIC piece Recovery processing of Figure 17, can carry out reference to Figure 17, and for simplicity by the specific descriptions of omitting same section.
More particularly, it is 8 FIC sections of the FIC section of " 7 " that the FIC section that collection is " 0 " from FIC_segment_num field value starts to FIC_segment_num field value.,, in the time having removed the FIC section header of each FIC section, recovered a FIC piece thereafter.More particularly, in the time having collected the payload of 8 FIC sections, recover (formation) a FIC piece.Now, identified empty FIC section by the FIC_type field in corresponding empty FIC section header.But empty FIC section is dropped, and does not use in FIC piece Recovery processing.
Meanwhile, suppose to transmit multiple FIC pieces separately with different protocol versions by a M/H frame, and receiving system can be processed all FIC pieces separately with different protocol versions.Now, when the FIC section separately with different protocol versions of dividing from multiple FIC pieces is normally received, during without any mistake, receiving system can be carried out normal recovery to having separately multiple FIC pieces of different protocol versions.But if there is the mistake being caused by burst noise in multiple FIC pieces separately with different protocol versions, receiving system can not be carried out normal recovery to having separately multiple FIC pieces of different protocol versions.
For example, the FIC piece that to suppose master agreement version be " 01 " for the FIC piece of " 00 " and master agreement version is sent to a FIC (, a M/H frame) simultaneously.And, as shown in Figure 19 (a), also suppose because the mistake that burst noise causes causes sending FIC section 4 to the FIC sections 7 of the FIC piece that master agreement version is " 00 " and send the not received system of FIC section 0 to FIC section 3 that master agreement version is the FIC piece of " 01 " receiving.
In this case, receiving system is also used FIC_segment_num field and the FIC_last_segment_num field in FIC section header, starts 8 FIC sections of the FIC section to FIC_segment_num field value as " 7 " to collect FIC section from FIC_segment_num field value as " 0 "., as Figure 19 (b) as shown in, remove 8 FIC sections FIC section header separately, thereby form a FIC piece thereafter.In this case, because the FIC section that the FIC_segment_num field value FIC section that is " 0 " is divided with the FIC piece that is " 00 " from master agreement version is corresponding, so the master agreement version of formed FIC piece is identified as " 00 " by receiving system, as shown in Figure 19 (b).
But, in the case of the FIC piece shown in Figure 19 (b), FIC section 0 to FIC section 3 and master agreement version are that the FIC section transmission data of FIC piece of " 00 " are corresponding, and FIC section 4 to the FIC sections 7 FIC section that is the FIC piece of " 01 " with master agreement version to transmit data corresponding.Therefore, in the time occurring in FIC section due to burst noise to lose, the set that receiving system can have transmission the FIC section of the FIC piece of 2 kinds of different protocol versions is identified as the set of the FIC section of transmitting the FIC piece with single protocol version, thereby has problems in the time recovering FIC piece.In addition,, in the time going wrong in FIC piece Recovery processing as mentioned above, receiving system can not identify and correctly not carry out the recovery of FIC piece.Therefore, receiving system can be obtained the RS frame corresponding with the assemblage of asked mobile service, thereby causes very serious problem.
In order to address the above problem, the present invention transmits the protocol version information of FIC piece by the FIC section header of each FIC section.At least one in master agreement version information and the secondary protocol version information of the protocol version information of the FIC piece transmitting by FIC section header according to the embodiment of the present invention, and corresponding FIC piece is corresponding.
Figure 20 is exemplified with according to the syntactic structure of the FIC section header of another embodiment of the present invention.FIC_Chunk_major_protocol_version field is added in addition to the syntactic structure of the FIC section header shown in Figure 16 herein.
More particularly, the FIC section header of Figure 20 can comprise FIC_type field, FIC_Chunk_major_protocol_version field, error_indicator field, FIC_segment_num field and FIC_last_segment_num field.Except FIC_Chunk_major_protocol_version field, all the other fields are identical with the field of describing in Figure 16.Therefore, for the sake of simplicity, in Figure 20, the specific descriptions of identical content will be omitted.
According to an embodiment of the invention, FIC_Chunk_major_protocol_version field is corresponding to 2 bit fields, and it indicates the master agreement version of corresponding FIC piece.More particularly, the FIC_Chunk_major_protocol_version field in FIC section header has the value identical with FIC_major_protocol_version field in corresponding FIC piece header.Master agreement version for FIC piece grammer can be with reference to the description of the FIC piece header in Fig. 9.Therefore, the specific descriptions of identical content will be omitted at this for the sake of simplicity.
Figure 21 has the FIC section of FIC section header as shown in figure 20 exemplified with reception and recovers an example of FIC piece.In this case, also (for example suppose multiple FIC pieces, 2 FIC pieces) be sent to a FIC (, a M/H frame), each master agreement version of two FIC pieces differs from one another, and receiving system can be processed two FIC pieces separately with different master agreement versions.
More particularly, as shown in Figure 21 (a), (the FIC piece that to suppose master agreement version be " 01 " for the FIC piece of " 00 " and master agreement version is sent to a FIC simultaneously, a M/H frame), and due to the mistake that burst noise causes, receiving system does not receive for sending FIC section 4 to FIC sections 7 that master agreement version is the FIC piece of " 00 " and for sending FIC section 0 to the FIC section 3 of the FIC piece that master agreement version is " 01 ".
Now, receiving system utilizes FIC_segment_num field, FIC_last_segment_num field and FIC_Chunk_major_protocol_version field in FIC section header to recover FIC piece.
More particularly, due to from FIC section 0 initial to the FIC_Chunk_major_protocol_version field value of FIC section 3 from different respectively from the initial FIC_Chunk_major_protocol_version field value to FIC section 7 of FIC section 4, although FIC segment number is continuous, if but FIC piece protocol version differs from one another, data can not form single FIC piece.
As shown in Figure 21 (b), collect 4 FIC sections for the initial FIC section that is " 3 " to FIC_segment_num field value of the FIC section of " 0 " from FIC_segment_num field value according to the FIC processor 121 of receiving system of the present invention.Thereafter, removing 4 FIC sections FIC section header separately, is the FIC piece of " 00 " thereby form master agreement version.In addition, FIC processor 121 is collected 4 FIC sections for the initial FIC section that is " 7 " to FIC_segment_num field value of the FIC section of " 4 " from FIC_segment_num field value.Thereafter, removing 4 FIC sections FIC section header separately, is the FIC piece of " 01 " thereby form master agreement version.
Therefore, can prevent following problem: in the time occurring in FIC section due to burst noise to lose, the set that receiving system can have transmission a FIC section of the FIC piece of 2 kinds of different protocol versions is identified as transmission and has the set of the FIC section of the FIC piece of single protocol version.
More particularly, by even distribute the protocol version information of corresponding FIC piece in FIC section header, even if receive the mixture of the multiple FIC sections corresponding from the FIC piece in single M/H frame with different protocol versions, the present invention also can only collect the FIC section corresponding with identical protocol version, thereby recovers FIC piece.
Now, in the time that FIC piece is resumed, as shown in figure 21, FIC piece is not recovered completely.For example, master agreement version be " 00 " FIC lost block from FIC_segment_num field value 4 FIC sections for the initial FIC section that is " 7 " to FIC_segment_num field value of the FIC section of " 4 ".In addition, master agreement version be " 01 " FIC lost block from FIC_segment_num field value 4 FIC sections for the initial FIC section that is " 3 " to FIC_segment_num field value of the FIC section of " 1 ".
Therefore, according to the embodiment of the present invention, FIC piece is not resumed in this case.More particularly, in the time having collected all FIC sections with identical master agreement version, and in the time that the quantity of collected FIC section is less than the quantity of the FIC section of dividing from corresponding FIC piece, corresponding FIC piece is not resumed.
Now, can carry out taking single subframe as unit or taking single M/H frame as unit and collect FIC section to recover the processing of a FIC piece.This is because identical FIC piece can repeat, and then in single subframe, transmits, and because identical FIC piece can repeat, then in single M/H frame, transmits.In addition, also can be taking the subframe of being scheduled to (or preassigned) quantity as unit or carry out the processing of collecting FIC section taking the M/H frame of (or preassigned) quantity of being scheduled to as unit.
In addition,, according to an embodiment of the invention, suppose in single M/H frame simultaneously and deposit the FIC piece with another master agreement version, and receiving system can be processed two kinds of FIC pieces separately with different master agreement versions.In this case, check the current FIC segment number of each FIC section, numbering and the master agreement version of last FIC section, thus the FIC section with the master agreement version identical with the master agreement version of receiving system can be collected, thus form FIC piece.
Alternatively, in the time supposing that existence has the FIC piece of another master agreement version simultaneously in single M/H frame, and suppose that receiving system only can process in two kinds of master agreement versions, recover FIC piece from the FIC section that represents its accessible master agreement version with signal.
Meanwhile, as mentioned above, the present invention uses FIC piece, to send mapping (or configuration) information between assemblage and mobile service in M/H frame.Herein, in the time there is reconstruct, wherein, assemblage in current M/H frame and the map information between mobile service are different from assemblage in next M/H frame and the map information between mobile service, the present invention can use at least one the FIC piece from M/H frame before corresponding reconstruct, to use in advance signal indication map information between assemblage and mobile service (or carrying out signaling in advance) in M/H frame, in this M/H frame, there is reconstruct.In description of the invention, by reconstruct occur before M/H frame be called current M/H frame, and reconstruct occur after M/H frame be called next M/H frame.
In addition, according to the embodiment of the present invention, from single M/H frame be alternately sent in current M/H frame with the FIC piece of the map information between signal indication assemblage and mobile service and in next M/H frame with the FIC piece of the map information between signal indication assemblage and mobile service.Herein, according to the embodiment of the present invention, according to time order and function order, the FIC piece with the map information between signal indication assemblage and mobile service in next M/H frame is placed in current M/H frame after the FIC piece with the map information between signal indication assemblage and mobile service, and after the FIC piece with the map information between signal indication assemblage and mobile service, transmits in current M/H frame.More particularly, first receiving system is received in the FIC piece with the map information between signal indication assemblage and mobile service in current M/H frame, is then received in after a while the FIC piece with the map information between signal indication assemblage and mobile service in next M/H frame.
Now, in the time receiving FIC piece and it recovered, current_next_indicator field in the FIC piece header that the utilization of the FIC processor 121 of receiving system is recovered, to determine that signaling information in the payload that is included in each FIC piece is corresponding to the assemblage in current M/H frame and the map information between mobile service or corresponding to the assemblage in next M/H frame and the map information between mobile service.For the sake of simplicity, below by the map information between the assemblage in M/H frame and mobile service the assemblage configuration information also referred to as M/H frame.
Figure 22 is exemplified with the situation of exemplary generation reconstruct, and wherein, the assemblage configuration information of current M/H frame is different from the assemblage configuration information of next M/H frame.With reference to Figure 22, by " ..., k-1, k, k+1, k+2, k+3 ... " part of instruction represents each M/H frame.And in this example, reconstruct occurs in (k+2) individual M/H frame.As shown in figure 22, the M/H frame before there is reconstruct comprises two assemblages and seven TNoG.And the M/H frame after there is reconstruct comprises three assemblages and seven TNoG.
As shown in figure 22, when when being sent to quantity, the change that is sent to the quantity of mobile service of each assemblage and the quantity of the TNoG of each subframe of assemblage of each M/H frame reconstruct is occurred, master agreement version information and the secondary protocol version information of FIC piece remain unchanged.But the FIC_version field value in TPC data changes.
Figure 22 shows FIC_version field value in the TPC data in (k+1) individual M/H frame to be increased (or increasing progressively) " 1 " and is updated to afterwards the example of " 6 ", and shows current_next_indicator field value in the FIC piece header in (k+1) individual M/H frame and change to the example of " 0 ".
Figure 23 obtains processing exemplified with exemplary RS frame when there is reconstruct in (k+2) individual M/H frame time and in the time alternately transmitting the assemblage configuration information of current M/H frame and the assemblage configuration information of next M/H frame from (k+1) individual M/H frame.
With reference to (k+1) individual M/H frame of Figure 23, the FIC piece that sends the assemblage configuration information of current M/H frame with signal is received early than the FIC piece of the assemblage configuration information that sends next M/H frame with signal, thereby is resumed.
Now, as shown in figure 23, when at the middle part of (k+1) individual M/H frame to comprising that the physical channel of required assemblage carries out when tuning, can obtain from (k+1) individual M/H frame the assemblage configuration information of (k+2) individual M/H frame.More particularly, in the time there is reconstruct, to send to corresponding reconstruct M/H frame before to change the map information between assemblage and the mobile service in mobile broadcast with the FIC piece that the assemblage configuration information of the M/H frame that reconstruct occurs is carried out to signal transmission by carrying out in advance, the present invention can promptly obtain the assemblage configuration information of the M/H frame (, the M/H frame of corresponding reconstruct has occurred) that corresponding reconstruct has wherein occurred.And, by utilizing the assemblage configuration information of (k+2) the individual M/H frame obtaining from (k+1) individual M/H frame, the present invention can obtain the RS frame that is sent to (k+2) individual M/H frame, thereby can recover obtained RS frame completely.
With reference to Figure 24, except the end part at k M/H frame to comprise required assemblage physical channel carry out tuning, remaining tuning processing is identical with the treatment step shown in Figure 23.Now, in the time that receiving system cannot receive the part of the RS frame corresponding with 20% of about M/H frame, can be by processing and recover whole RS frame with RS-CRC decoding and SCCC decoding.For example, suppose the end of k M/H frame part to comprise the physical channel of required assemblage carry out tuning, and from first FIC piece of (k+1) individual M/H frame intactly (or fully) obtain the signaling information of (k+1) individual M/H frame.
In this case, in the time receiving first FIC piece of (k+1) individual M/H frame, not yet can receive the RS frame that is sent to (k+1) individual M/H frame.But, when the part not receiving be equivalent to (k+1) individual M/H frame about 20% time, by recover to be sent to the whole RS frame of (k+1) individual M/H frame with RS-CRC decoding and SCCC decoding processing.In addition, even there is reconstruct in (k+1) individual M/H frame, the present invention can use the signaling information of (k+2) the individual M/H frame obtaining from (k+1) individual M/H frame, intactly to recover to be sent to the RS frame of (k+2) individual M/H frame.
As mentioned above, the FIC block data structure in the tuning point based on physical channel and the M/H frame before there is reconstruct, the present invention can promptly obtain and recover RS frame, thereby can provide required RS frame to user.
But, as mentioned above, when have the FIC piece of the assemblage that transmits with signal in current M/H frame and the map information between mobile service and transmit the assemblage in next M/H frame with signal and when the FIC piece of the map information between mobile service, also there will be in this case the identical problem occurring when receive the FIC piece with different protocol versions in single M/H frame time in single M/H frame simultaneously.More particularly, from transmit with signal transmit the assemblage in current M/H frame and the map information between mobile service FIC piece FIC section with transmit a FIC piece of FIC section recovery that transmits the FIC piece of the assemblage in next M/H frame and the map information between mobile service with signal, this wherein there will be mistake.As mentioned above, in the time going wrong, cannot obtain suitably the assemblage configuration information of next M/H frame from recovered FIC piece in the recovery process of FIC piece.Therefore, also cannot obtain suitably and recover to be sent to the RS frame of next M/H frame.
For example, when receive with the order of mixing the assemblage that transmits with signal in current M/H frame and the map information between mobile service FIC piece FIC section and transmit the assemblage in next M/H frame with signal and when the FIC section of the FIC piece of the map information between mobile service, receiving system cannot be determined received corresponding FIC section and belong to that to transmit the FIC section of FIC piece of the assemblage in current M/H frame and the map information between mobile service with signal corresponding, or to transmit the FIC section of FIC piece of the assemblage in next M/H frame and the map information between mobile service with signal corresponding with belonging to.Therefore, there will be above-mentioned problem.
In addition, in the time that the mistake causing due to burst noise is lost FIC section, receiving system also can determine received corresponding FIC section and belong to that to transmit the FIC section of FIC piece of the assemblage in current M/H frame and the map information between mobile service with signal corresponding, or with belong to that to transmit the FIC section of FIC piece of the assemblage in next M/H frame and the map information between mobile service with signal corresponding.Therefore, in this case, also can there is above-mentioned problem.
Similarly, in the time receiving as shown in figure 23 TPC data and FIC section, the problems referred to above also can occur.More particularly, as Figure 25 1. as shown in, in first FIC section of FIC piece that transmits the assemblage in next M/H frame and the map information between mobile service with signal, the FIC_version field value in TPC data has increased " 1 ".Correspondingly, as Figure 25 2. as shown in, receiving system can exit from time slicing pattern, thereby collects (or, gather) FIC section.
In addition, as Figure 25 8. as shown in, receiving system is utilized FIC_segment_num field and the FIC_last_segment_num field in each FIC section header of collected FIC section, only to collect the FIC section that forms single FIC piece, thereby adjust each FIC section with the order of each FIC segment number.Thereafter, receiving system removes header from the FIC section of each adjustment.Correspondingly, as Figure 25 4. as shown in, formed single FIC piece.Then, receiving system is obtained the assemblage configuration information of M/H frame from the FIC piece forming.Subsequently, as Figure 25 5. as shown in, according to obtained assemblage configuration information, receiving system entry time fragmentation schema.
But, with reference to as Figure 25 8. as shown in the FIC section of collection, obviously the FIC section that, transmits the FIC piece of the assemblage in current M/H frame and the map information between mobile service with signal is (simultaneous) mixing with the FIC section of the FIC piece that transmits the assemblage in next M/H frame and the map information between mobile service with signal.More particularly, Figure 25 8. the example of collecting improperly FIC section be shown.This is because receiving system cannot determine that corresponding FIC section is to belong to the FIC section that transmits the FIC piece of the assemblage configuration information in current M/H frame with signal, still belongs to the FIC section that transmits the FIC piece of the assemblage configuration information in next M/H frame with signal.
In addition, when as Figure 25 4. as shown in while forming FIC piece, receiving system determines that corresponding FIC piece is transmitting the assemblage configuration information of next M/H frame with signal.But FIC piece comprises to be included in signal and transmits the partial data in the FIC piece of the assemblage configuration information in current M/H frame.More particularly, Figure 25 4. the example being resumed in the time that FIC piece comprises (incorrect) information of mistake be shown.Correspondingly, the assemblage configuration information obtaining due to the FIC piece from incorrect recovery, corresponding to incorrect information, can correctly not obtained and be recovered so be sent to the RS frame of next M/H frame.
According to the embodiment of the present invention, in order to address this is that, in the time that the FIC section header by each FIC section transmits M/H frame identifying information, M/H frame identifying information informs that corresponding FIC section is to transmit the FIC section of the FIC piece of the assemblage configuration information in current M/H frame with signal, or transmits the FIC section of the FIC piece of the assemblage configuration information in next M/H frame with signal.According to the embodiment of the present invention, the M/H frame identifying information transmitting by FIC section header is corresponding with current_next_indicator field.
Figure 26 is exemplified with according to the syntactic structure of the FIC section header of another embodiment of the present invention.More particularly, current_next_indicator field is also included in the syntactic structure of the FIC section header shown in Figure 20.According to the present invention, current_next_indicator field is appointed as to 1 bit.
More particularly, the FIC section header of Figure 26 can comprise FIC_type field, FIC_Chunk_major_protocol_version field, current_next_indicator field, error_indicator field, FIC_segment_num field and FIC_last_segment_num field.Because the description for FIC_type field, error_indicator field, FIC_segment_num field and FIC_last_segment_num field can be with reference to Figure 16, so will omit the specific descriptions of identical content for the sake of simplicity.
FIC_Chunk_major_protocol_version field is corresponding to 2 bit fields, and it indicates the master agreement version of corresponding FIC piece.Now, FIC_Chunk_major_protocol_version field should be identical with the value of the FIC_major_protocol_version field in corresponding FIC piece header.Due to can be with reference to the description of the FIC piece header shown in Fig. 9, for the sake of simplicity, the specific descriptions of master agreement version of FIC piece grammer will be omitted.
Current_next_indicator field is corresponding to 1 bit indicator, wherein, in the time being set to " 1 ", the part that FIC section corresponding to instruction carried to the FIC piece that is applicable to current M/H frame.Alternatively, in the time that current_next_indicator field is set to " 0 ", the part that instruction FIC section has been carried the corresponding FIC piece that is applicable to next M/H frame by current_next_indicator field.In the previous case, with the nearest version that is set to the FIC piece that the current_next_indicator field value of " 1 " transmits by current be available.
In addition,, in the signaling information region in data group, together distribute the TPC data that are then transmitted to comprise the parameter mainly using in physical layer block with FIC data.And because TPC data non-interleaved transmits, receiving system can visit taking time slot as unit TPC data.According to the embodiment of the present invention, the characteristic that the TPC data that comprise FIC_version field can be received taking time slot as unit by use, in the time upgrading FIC piece, receiving system can be used the FIC_version field of TPC data to determine the more new state of corresponding FIC piece.And in the time the more new state of corresponding FIC piece being detected, receiving system exits from time slicing pattern, so that FIC section can be integrated (or combination).
Figure 27 is exemplified with an example of the syntactic structure of TPC data.TPC data can comprise sub_frame_number field, slot_number field, parade_id field, starting_group_number (SGN) field, number_of_groups (NoG) field, parade_repetition_cycle (PRC) field, RS_frame_mode field, RS_code_mode_primary field, RS_code_mode_secondary field, SCCC_block_mode field, SCCC_outer_code_mode_A field, SCCC_outer_code_mode_B field, SCCC_outer_code_mode_C field, SCCC_outer_code_mode_D field, FIC_version field, parade_continuity_counter field, TNoG field and TPC_protocol_version field.
Sub_frame_number field is indicated the numbering of the current subframe in corresponding M/H frame, is in order to carry out M/H frame synchronization by its transmission.The value of sub_frame_number field is by from 0 to 4 scope.
Slot_number field is the current time slots numbering in subframe, is in order to carry out M/H frame synchronization by its transmission.It is worth in from 0 to 15 scope.
Parade_id field is identified the queue that this group belongs to.The value of this field can be the value of any 7 bits.Each queue in M/H transmits will have unique parade_id.In this case, will utilize ensemble_id to carry out the communication of parade_id between physical layer and management level, wherein, form ensemble_id by increasing by a bit to the left side of parade_id.If ensemble_id combines for the principal series transmitting by this queue, the highest significant position (MSB) increasing will be " 0 ".Otherwise if ensemble_id is for the auxiliary assemblage transmitting by this queue, the highest significant position (MSB) increasing will be " 1 ".
Starting_group_number (SGN) field is first slot_number of the queue (after the time-gap number for all preceding queues as calculated) that belongs to of this group (group).
Number_of_groups (NoG) field is that the quantity of the group of the queue assignment that in subframe, this group belonged to subtracts 1, and for example, NoG=0 is illustrated in a group in subframe and is assigned to this queue.The scope of the value of NoG will be from 0 to 7.Can carry out the timeslot number of dispensed to corresponding queue according to SGN and NoG.
Parade_repetition_cycle (PRC) field is to subtract 1 the circulation timei of the transmission queue that specifies taking M/H frame as unit.
RS_frame_mode field instruction single queue carries single RS frame and still carries two RS frames.
The RS code pattern of RS_code_mode_primary field pointer to main RS frame.
The RS code pattern of RS_code_mode_secondary field pointer to auxiliary RS frame.
How the instruction of SCCC_block_mode field is dispensed to SCCC piece by the M/H piece in data group.
SCCC_outer_code_mode_A field is indicated the SCCC external schema code for region A in data group.
SCCC_outer_code_mode_B field is indicated the SCCC external schema code for region B in data group.
SCCC_outer_code_mode_C field is indicated the SCCC external schema code for region C in data group.
SCCC_outer_code_mode_D field is indicated the SCCC external schema code for region D in data group.
The version of FIC_version field instruction FIC data.More particularly, FIC_version field represents the version of FIC block data structure.The value of this field is identical by being set to all TPC data structures with transmitting by a M/H frame, and while existing current_next_indicator field to be set to the FIC section of " 0 " in the subframe that is transmitting TPC data structure, the value of this field will increase progressively 1.For example, in the time being included in the numbering of the mobile service in assemblage 0 and changing into 3 from 2, the value of FIC_version field is constant.
Parade_continuity_counter field is incremented to 0 to 15, and increases progressively 1 for every (PRC+1) individual M/H frame.For example, if PRC=011, parade_continuity_counter field increases progressively for every four M/H frames.
TNoG field is indicated the sum of the data group transmitting in subframe.In other words, it be all queues in subframe NoG and.Its value will (comprise 1 and 16) in 0 to 16 scope.The use of TNoG field both for current M/H frame information also for the signaling shifting to an earlier date.
TPC_protocol_version field is corresponding to 5 bit unsigned integer, and represents the version of corresponding TPC syntactic structure.2 highest significant positions are main release levels; Three least significant bits are subedition ranks, are read as: at the corresponding levels other of key plate changes the change of the non-back compatible rank of instruction.Suppose that main release level remains unchanged, the change of subedition rank is by the change of instruction back compatible rank.The initial value of this field will be " 11111 ".When the version in the future of this standard changes TPC structure each time, at least one bit will be changed to form the former original value of this field.Other version value can in the future used for reserved bit or for the change of the grammer that defines.First this change will be to change into " 00 " or " 000 ", so this field increases progressively for later change in the mode identical with other field.
But the information being included in TPC data presenting at this is only exemplary.And, because those of ordinary skill in the art can easily adjust and revise the increase and the deletion that are included in the information in TPC, therefore do not limit the invention to illustrated example herein.
Because the value of the TPC data for each queue (except Sub_Frame_number field and Slot_number field) does not change at M/H image duration, therefore repeatedly transmit identical information by all M/H groups that belong to corresponding queue in M/H frame.This allows very healthy and strong and receives reliably TPC data.Because Sub_Frame_number and Slot_number are the Counter Value increasing progressively, owing to having transmitted the desired value of rule, therefore this Sub_Frame_number and Slot_number are also healthy and strong.
Thereby Figure 28 is exemplified with an example that receives the TPC data recovery FIC piece that has separately the FIC section of FIC section header as shown in figure 26 and have structure as shown in figure 27.More particularly, as Figure 28 1. as shown in, when the FIC_version of TPC data structure field value increases when " 1 ", receiving system determines that the data structure of corresponding FIC piece is updated.Then, as Figure 28 2. as shown in, receiving system exits from time slicing pattern, (or collection) FIC section collecting.
Thereafter, as Figure 28 8. as shown in, receiving system is utilized FIC_segment_num field, FIC_last_segment_num field and the current_next_indicator field in each FIC section header of collected FIC section, only to collect the FIC section that forms a FIC piece.Subsequently, receiving system is adjusted the FIC section of each collection with the order of each FIC segment number.Then, as Figure 28 4. as shown in, receiving system removes the header of each FIC section, thereby forms FIC piece.Then, as Figure 28 5. as shown in, receiving system is obtained the assemblage configuration information of M/H frame from the FIC piece forming, with according to the assemblage configuration information entry time fragmentation schema being obtained.
In the case of Figure 28 8., when only collecting while forming the FIC section of a FIC piece, can use in addition the FIC_Chunk_major_protocol_version field in FIC section header.More particularly, receiving system can be used segment_num field, FIC_last_segment_num field, current_next_indicator field and FIC_Chunk_major_protocol_version field, only to collect the FIC section that transmits the FIC piece of the assemblage configuration information of next corresponding with identical protocol version (or, current) M/H frame with signal.Subsequently, receiving system is adjusted the FIC section of each collection with the order of each FIC segment number.Then, receiving system removes the header of each FIC section, thereby forms FIC piece.As Figure 28 4. as shown in, in the time of formation FIC piece described above, can be only form FIC piece by the FIC section corresponding with the FIC piece of assemblage configuration information that transmits next M/H frame with signal.
Therefore, receiving system can prevent by collection belong to signal transmit the assemblage configuration information in current M/H frame FIC piece FIC section and belong to the FIC section that transmits the FIC piece of the assemblage configuration information in next M/H frame with signal and construct the problem of single FIC piece.More particularly, M/H frame identifying information is dispensed to each FIC section header by the present invention.Herein, the signaling information that M/H frame identifying information can be identified the payload that is transferred into each FIC section is corresponding with the signaling information of current M/H frame, or corresponding with the signaling information of next M/H frame.Thereby, receiving system can without any mistake obtain the assemblage configuration information of next M/H frame from FIC piece.Correspondingly, the RS frame of next M/H frame can correctly be obtained and be recovered to be sent to receiving system.
Figure 29 and Figure 30 are exemplified with according to the flow chart for the treatment of the step of FIC piece that illustrates of an embodiment of the invention.
Suppose that the receiving system (or receiver) of applying corresponds respectively to the receiving system that cannot process FIC piece in the time that the master agreement version of corresponding FIC piece is updated in Figure 29 and Figure 30.Also hypothesis receiving system in the time that the secondary protocol version of corresponding FIC piece is updated only can be processed a part of FIC piece.In addition, suppose that the master agreement version of the FIC piece that can be processed by receiving system and secondary protocol version are stored in corresponding receiving system.
More particularly, in step 501, use and above-mentionedly recover FIC piece for any one of method of recovering FIC piece from multiple FIC section payload.In this article, FIC piece is made up of FIC piece header and FIC piece payload.And, suppose that the syntactic structure of FIC piece header is identical with the syntactic structure shown in Fig. 9, and the syntactic structure of FIC piece payload is identical with the syntactic structure shown in Figure 12.
In the time having recovered FIC piece in step 501, a part for FIC piece header is resolved to obtain the field information (S502) being included in FIC piece header.This field information can comprise the information of at least one extraction from FIC_major_protocol_version field, FIC_minor_protocol_version field, FIC_chunk_header_extension_length field, ensemble_loop_header_extension_length field, M/H_service_loop_extension_length field, current_next_indicator field, transport_stream_id field and num_ensembles field.
Whether the master agreement version of the FIC piece that subsequently, receiving system inspection recovers is updated (S503).Can compare and determine renewal with the master agreement version that is stored in the FIC piece receiving system by the master agreement version that the FIC_major_protocol_version field in the piece header of recovered FIC piece is obtained.According to an embodiment of the invention, if the value of the master agreement version corresponding with the FIC piece obtaining in step 502 is greater than the value of the master agreement version corresponding with being stored in FIC piece in receiving system, receiving system determines that the master agreement version of the FIC piece recovering is updated.
Then,, in the time that receiving system in step 503 determines that the master agreement version of the FIC piece recovering is updated, receiving system can not complete the processing (S504) of the FIC piece to recovering in step 501.In other words, the payload of the FIC piece recovering in step 501 is not processed.
Meanwhile, if receiving system determines that the master agreement version of the FIC piece recovering is not updated in step 503, whether the secondary protocol version of the FIC piece that receiving system inspection institute recovers is updated (S505).Can compare and determine renewal with the secondary protocol version that is stored in the FIC piece receiving system by the secondary protocol version that the FIC_minor_protocol_version field in the piece header of recovered FIC piece is obtained.
According to one embodiment of the present invention, if the value of the secondary protocol version corresponding with the FIC piece obtaining in step 502 is greater than the value of the secondary protocol version corresponding with being stored in FIC piece in receiving system, receiving system determines that the secondary protocol version of the FIC piece recovering is updated.
If receiving system determines that the secondary protocol version of FIC piece is not updated in step 505, receiving system is processed (S506) to the assemblage circulation header in the payload of the FIC piece recovering in step 501, thereby obtains about the information (S507) of quantity that is included in the mobile service in corresponding assemblage.Can know the quantity of mobile service by reference to num_MH_services field.
After execution step 507, whether the secondary protocol version of the receiving system FIC piece that inspection institute recovers is again updated.Because verification method is identical with the method described in step 505, for the sake of simplicity, the specific descriptions of identical content will be omitted.
If the secondary protocol version of receiving system definite corresponding FIC piece in step 508 is not updated, receiving system is processed being contained in the circulation of the mobile service in handled assemblage (, M/H cycle of business operations) in step 505.The step of processing M/H cycle of business operations repeats the number of times identical with the quantity that is included in the mobile service in assemblage.
More particularly, process M/H cycle of business operations in step 509 after, receiving system inspection in step 509 handled mobile service whether be contained in last M/H business corresponding (S510) in handled assemblage circulation header in step 505.Num_MH_services field by reference to assemblage circulation header can be verified this information.
If the mobile service of checking is corresponding to last M/H business, receiving system advances to according to the step 511 of data processing method of the present invention so that next assemblage circulation header is processed.On the other hand, if checking mobile service do not correspond to last M/H business, receiving system step back (or returning) to according to the step 508 of data processing method of the present invention so that next the M/H cycle of business operations being included in current assemblage circulation header is processed.
If determine that in step 510 mobile service of inspection is corresponding with last M/H business, whether receiving system is checked comprising the assemblage that has last M/H business with to pass through recovered FIC piece corresponding with the last assemblage of signal transmission in step 511.Can verify this information by reference to the num_ensembles field of FIC piece.
If determine that current assemblage, corresponding to last assemblage, has completed the processing (S512) to FIC piece.But if determine that current assemblage does not correspond to last assemblage, receiving system is stepped back (or returning) to according to the step 505 of data processing method of the present invention, processes with next assemblage in the FIC piece being recovered being included in.
Meanwhile, if determine that in step 505 the secondary protocol version of corresponding FIC piece is updated, the length information of receiving system based on be sent to the extended field of FIC piece with signal processed all the other fields except corresponding extended field.In this article, skip corresponding extended field.
More particularly, if the secondary protocol version of FIC piece is changed, the length information of the byte of the n1 based on obtaining from FIC_chunk_header_extension_length field (wherein, n1 >=0), skip the end that is added into corresponding FIC piece header n1 byte FIC piece header extension field and it is not processed to (S513).
In addition,, in the time that the secondary protocol version of FIC piece has been changed, the assemblage circulation header portion that can be decoded by receiving system is processed to (S514).Now, the information of the byte length of the n2 based on obtaining from ensemble_loop_header_extension_length field (wherein, n2 >=0), skip the end that is added into corresponding assemblage circulation header n2 byte assemblage circulation header extension field and it is not processed to (S515).
In addition,, in the time that the secondary protocol version of FIC piece has been changed, the M/H cycle of business operations part that can be decoded by receiving system is processed to (S516).Now, the information of the byte length of the n3 based on obtaining from M/H_service_loop_extension_length field (wherein, n3 >=0), skip the end that is added into corresponding M/H cycle of business operations n3 byte M/H cycle of business operations extended field and it is not processed to (S517).
After in step 516 and step 517, to M/H, cycle of business operations has been carried out processing, the mobile service that receiving system inspection is processed in step 516 with in step 517 whether with last the M/H business corresponding (S510) in assemblage circulation header that is included in of processing in step 514 and step 515.Can know this information by reference to the circulate num_MH_services field of header of assemblage.
If mobile service is corresponding to last M/H business, receiving system advances to step 511 so that next assemblage circulation header is processed.On the contrary, if mobile service does not correspond to last M/H business, receiving system is returned to step 508 and is processed with next M/H cycle of business operations of the assemblage circulation header to corresponding.
In step 511, once receiving system determines that in step 510 mobile service is corresponding to last M/H business, whether receiving system is then checked the assemblage of last M/H business of carrying corresponding with last assemblage transmitting by signal from the FIC piece recovering.Can check this information by reference to the num_ensembles field of FIC piece.
Thereafter, when receiving system determine assemblage corresponding to transmit by signal from recovered piece last assemblage time, complete the processing (S512) to FIC piece.But, if determining this assemblage, receiving system do not correspond to last assemblage transmitting by signal from recovered piece, receiving system is returned to step 505 to process next assemblage in the FIC piece that is included in recovery.
Meanwhile, if receiving system according to the present invention, corresponding to the receiving system that can be received in the change in FIC master agreement version, is carried out normal process to the FIC piece recovering from multiple FIC sections.
In addition, if receiving system according to the present invention is corresponding to the receiving system that can be received in the change in the secondary protocol version of FIC, and in the time confirming that the secondary protocol version of FIC piece has been updated, based on the length information that is sent to the extended field of FIC piece by signal, FIC piece is processed until complete the processing of corresponding extended field.
