Data format structures

Meanwhile, the data structure used in mobile broadcast technology according to the embodiment of the present invention can include data Group structure and RS frame structures, will be described in detail now.

Example arrangements of the Fig. 2 exemplified with the data group according to the present invention.Fig. 2 is shown the data knot according to the present invention The data group of structure is divided into an example of 10 M/H blocks (that is, M/H blocks 1 (B1) arrive M/H blocks 10 (B10)).In this example, Each M/H block length is 16 sections.Reference picture 2,5 sections and M/ before that RS parity datas are only distributed to M/H blocks 1 (B1) 5 sections of part after H blocks 10 (B10).Do not include RS parity datas in region A to the D of data group.More specifically, , can be according to the characteristic of each M/H block in the data group when assuming that a data group is divided into region A, B, C and D Each M/H block is included in from region A to any one of region D.

Herein, data group is divided into multiple regions by different purposes are used for.More specifically, with compared with Compare in the region of high interference degree, it is believed that do not interfere with or the region of main business data with extremely low annoyance level has (or stronger) receptivity of greater resistance.In addition, when the system for using insertion and transmission given data in data group When (it is known that data are known based on the agreement sent between system and reception system), and when will be in mobile service number When successive longer given data is periodically inserted in, the given data with predetermined length can be periodically inserted In the region disturbed to not acceptor's business datum (that is, the region that main business data are not mixed with).However, due to main business data Interference, it is difficult to by given data be inserted periodically into acceptor's business datum interference region, and be also difficult to by it is successive compared with Long given data is inserted into the region of acceptor's business datum interference.

Reference picture 2, M/H blocks 4 (B4) to M/H blocks 7 (B7) correspond to the region of not acceptor's business datum interference.Shown in Fig. 2 Data group in M/H blocks 4 (B4) correspond to the region of the interference for not occurring carrying out autonomous traffic data to M/H blocks 7 (B7). In the example, longer given data sequence has been all inserted into the starting and ending of each M/H block.In the description of the invention, The region representation that M/H blocks 4 (B4) to M/H blocks 7 (B7) will be included is " region A (=B4+B5+B6+B7) ".Should as described above, working as When data group includes the region A of the longer given data sequence with starting and the ending for being inserted in each M/H block, reception system Equilibrium can be performed by using the channel information that can be obtained from the given data.Therefore, from one in region A to region D (or obtaining) most strong equalization performance can be obtained in individual region.

In the example of the data group shown in Fig. 2, M/H blocks 3 (B3) and M/H blocks 8 (B8) come from corresponding to seldom The region of the interference of main business data.Herein, only longer given data sequence is inserted in each M/H block B3 and B8 one end Row.More specifically, due to carrying out the interference of autonomous traffic data, longer given data sequence is inserted in the ending of M/H blocks 3 (B3) Row, and insert another longer given data sequence in the starting of M/H blocks 8 (B8).In the present invention, will be including M/H The region representation of block 3 (B3) and M/H blocks 8 (B8) is " region B (=B3+B8) ".As described above, when the data group includes having only During the region B for the longer given data sequence for being inserted in one end (starting ends up) of each M/H block, reception system can pass through Equilibrium is performed using the channel information that can be obtained from the given data.Therefore, compared with the C/D of region, can obtain (or To) stronger equalization performance.

Reference picture 2, M/H blocks 2 (B2) and M/H blocks 9 (B9) carry out autonomous traffic number corresponding to compared with the B of region with stronger According to interference region.Longer given data sequence can not be inserted in the either end of M/H blocks 2 (B2) and M/H blocks 9 (B9). Herein, the region for including M/H blocks (B2) and M/H blocks 9 (B9) is referred to as " region C (=B2+B9) ".Finally, shown in Fig. 2 In example, M/H blocks 1 (B1) and M/H blocks 10 (B10) carry out the dry of autonomous traffic data corresponding to compared with the C of region with stronger The region disturbed.Similarly, it is impossible to insert longer given data sequence in the either end of M/H blocks 1 (B1) and M/H blocks 10 (B10). Herein, the region for including M/H blocks 1 (B1) and M/H blocks 10 (B10) is referred to as " region D (=B1+B10) ".Due to region C/D It is separated by with the given data sequence farther, therefore when channel circumstance is subjected to frequent and unexpected change, connecing for region C/D can be made Receive performance degradation.

In addition, the data group includes specifying (or distribution) signaling information region of signaling information.In the present invention, signaling Information area can be since 4M/H blocks (B4) first paragraph untill a part for second segment.According to the reality of the present invention Mode is applied, the signaling information region for inserting signaling information can be since 4M/H blocks (B4) first paragraph to second segment Untill a part.More specifically, 276 (=207+69) individual bytes of the 4M/H blocks (B4) in each data group are appointed as Signaling information region.In other words, signaling information region is by the 1st section of 207 bytes of 4M/H blocks (B4) and preceding the 69 of the 2nd section Individual byte composition.The 1st section of 4M/H blocks (B4) corresponds to the 17th section or the 173rd section of VSB.

Herein, can be according to two distinct types of signaling channel data (that is, configured transmission channel (TPC) data With fast information channel in dab receiver (FIC) data) come be identified by signaling information region transmission signaling data.

Moreover, TPC data include the main parameter used in physical layer block.Also, because TPC data are non-interleaved And be transmitted, TPC data can be accessed in units of time slot in reception system.There is provided FIC data is to receive System is able to carry out fastext acquisition.Herein, FIC data include the cross-layer information between physical layer and upper strata.With subframe FIC data are interleaved for unit and are then sent to.

For example, as shown in Fig. 2 when data group includes 6 given data sequences, signaling information region is located at known to first Between data sequence and the second given data sequence.More specifically, first is inserted in last 2 sections of 3M/H blocks (B3) Primary data sequence, and insert the second given data sequence in the 2nd and the 3rd section of 4M/H blocks (B4).In addition, the 4th, 5th, the 6th and 7M/H blocks (B4, B5, B6 and B7) in each latter 2 sections in be respectively inserted into the 3rd given data sequence to 6 given data sequences.1st given data sequence and the 3rd given data sequence are separated by 16 between the 6th given data sequence Section.

Fig. 3 is exemplified with the RS frames according to an embodiment of the invention.

Under conditions of reception system to be switched to time slicing pattern, RS frames are received for each M/H frame.Each RS frame IP including each mobile service data or signaling data flows, and business mapping table (SMT) sector data may reside in entirely In portion's RS frames.SMT sector datas can be IP stream types, or different data types.By RS frame data distribute to it is many The corresponding region of individual data group, and send to reception system.

RS frames according to the embodiment of the present invention are made up of at least one M/H transmission bags (TP).Herein, M/H TP Including M/H headers and M/H payload.

M/H payload may include mobile service data and signaling data.More specifically, M/H payload can be with Mobile service data is only included, or signaling data can be only included, or can not only include mobile service data but also including signaling number According to.According to the embodiment of the present invention, M/H headers can be identified to being included in the data type in M/H payload (or Distinguish).More specifically, when M/H TP include the first M/H headers, this represents that the M/H payload only includes signaling data. In addition, when M/H TP include the 2nd M/H headers, this represents that the M/H payload had not only included signaling data but also including mobile industry Business data.Finally, when M/H TP include the 3rd M/H headers, this represents that the M/H payload only includes mobile service data. In the example depicted in fig. 3, RS frames are assigned for SMT IP datagram (IP datagram 1) and for two kinds of types of service IP datagram (IP datagram 2 and IP datagram 3).

Data transmission structure

Fig. 4 is exemplified with the structure for being used to send and receive the M/H frames of mobile service data according to the present invention.In Fig. 4 institutes In the example shown, a M/H frame is made up of 5 subframes, wherein each subframe includes 16 time slots.In this case, according to this The M/H frames of invention include 5 subframes and 80 time slots.In addition, in bag grade, a time slot (that is, is passed by 156 packets Defeated stream bag) constitute, in symbol level, a time slot is made up of 156 data segments.Here, the size of a time slot corresponds to The half (1/2) of VSB.More specifically, due to 207 bytes packet have with data segment identical data volume, Therefore, the packet before being interleaved is also used as data segment.Herein, two VSB are carried out in groups forming VSB frames.

Fig. 5 exemplified with VSB frames example arrangement, wherein, a VSB frame is by 2 VSB (that is, odd fields and even number ) composition.Herein, each VSB all includes field synchronization segments and 312 data segments.Time slot corresponds to mobile service number According to the basic time unit being multiplexed with main business data.

Herein, a time slot can either include mobile service data or only can be made up of main business data. If preceding 118 packets in time slot correspond to data group, remaining 38 data is bundled into as main business data packet.Another In individual example, when data group is not present in a slot, corresponding time slot is made up of 156 main business packets.

Meanwhile, the mobile service data of a RS frame in can be assigned to the Zone Full A/B/ in corresponding data group C/D, or at least one being assigned in the A/B/C/D of region.In embodiments of the present invention, can be by a RS frame Interior mobile service data is assigned to Zone Full A/B/C/D, or is assigned in region A/B and region C/D at least One.If distributing mobile service data by latter event (that is, one in region A/B and region C/D), then it is designated RS frames to region C/D of the RS frames with being assigned in corresponding data group of the region A/B in corresponding data group are different from each other.

According to the embodiment of the present invention, for sake of simplicity, the RS frames for the region A/B being assigned in corresponding data group are claimed For " main RS frames ", the RS frames for the region C/D being assigned in corresponding data group are referred to as " auxiliary RS frames ".In addition, main RS frames with it is auxiliary Queue of RS frames formation (or composition).More specifically, it is assigned to accordingly when by the mobile service data of a RS frame in During Zone Full A/B/C/D in data group, a queue sends a RS frame.On the contrary, working as the mobile industry of a RS frame in When business data are assigned to any one in region A/B and region C/D, most 2 RS frames can be transmitted in a queue.More specifically Say, RS frame patterns indicate whether queue sends a RS frame, or whether queue sends two RS frames.Using this RS frame patterns as TPC data are transmitted.Below, table 1 shows an example of RS frame patterns.

【Table 1】

Table 1 is exemplified with two bits of distribution to represent the example of RS frame patterns.For example, referring to table 1, when RS frame pattern values etc. When ' 00 ', this represents that a queue sends a RS frame.Also, when RS frame patterns value is equal to ' 01 ', this represents a team Row send two RS frames, i.e. main RS frames and auxiliary RS frames.More specifically, when RS frame patterns value is equal to ' 01 ', region will be directed to The data of A/B main RS frames are assigned to the region A/B of corresponding data group and are transmitted.Similarly, by for the auxiliary of region C/D The data of RS frames are assigned to the region C/D of corresponding data group and are transmitted.

As data group specify described in, also queue is designated as in subframe to separate as far as possible each other.Cause And, reception system can rapidly and efficiently be responded to any burst error that may occur in subframe.In addition, specifying team The method of row can be applied to whole M/H frames in the same manner, or differently be applied to each M/H frame.According to the embodiment of the present invention, Can be for each M/H frame difference ground specified queue, and for whole subframes specified queue in the same manner of M/H frame ins.More Say, M/H frame structures can be changed in units of M/H frames body.It therefore, it can more frequently and neatly adjust assemblage speed (ensemble rate)。

That is, the concept of M/H assemblages is applied in embodiments of the present invention, so as to define the set (or group) of business. Each M/H assemblage carries identical QoS, and it is encoded with identical FEC code.Moreover, each M/H assemblage has phase With unique identifier (that is, assemblage ID) and corresponding with continuous RS frames.

Fig. 6 is exemplified with the data transmission structure in physical layer according to the embodiment of the present invention.More specifically, Fig. 6 Show an example for being included in the FIC data in each data group and sent.As described above, by about 0.968 second M/H frames are divided into 5 subframes, wherein, the data group corresponding with multiple assemblages is present in each subframe in combination.And And, a pair data group corresponding with each assemblage is interleaved in units of M/H frames, to be carried out to the RS frames for belonging to an assemblage Configuration.In figure 6, there are two kinds of assemblages (wherein, NoG=4 and NoG=3) in each subframe.In addition, each data group Predetermined part (for example, 37 byte/data groups) is used to discretely individually transmit encoded FIC with RS frame data channel Data.Distribution to the FIC regions of each data group include one FIC sections.Herein, to entering to each FIC sections in units of subframe Row interweaves.For example, RS codings and SCCC coded treatments are applied to RS frame data, and should by RS codings and PCCC coded treatments With to FIC data.Moreover, it is identical with FIC data, RS codings and PCCC coded treatments are applied to TPC data.More specifically Say, (187+P, 187)-RS coded treatments applied to RS frame data, (51,37)-RS coded treatments are applied to FIC data, And (18,10)-RS coded treatments are applied to TPC.Herein, P is parity byte quantity.

It is classified signaling structure

Fast information channel in dab receiver (FIC)

In order to more rapidly (or more quickly) access the business currently broadcasted, adopted according to the reception system of the present invention With fast information channel in dab receiver (FIC).

More specifically, 121 pairs of Fig. 1 FIC processors are configured from FIC sections of FIC blocks.Then, in parsing FIC After block, the result of parsing is output to Service Manager 122 by FIC processors 121.

Syntactic structures of the Fig. 8 exemplified with the FIC blocks that the relation between mobile service and assemblage is mapped by FIC.Herein, FIC blocks include FIC blocks header and FIC block payload.

Syntactic structures of the Fig. 9 exemplified with the FIC block headers according to an embodiment of the invention.

Herein, FIC blocks header represents that the master agreement version of the non-back compatible in corresponding FIC blocks changes with signal, and And the secondary protocol version change of back compatible is also represented with signal.In addition, also represented with signal can be by secondary agreement for FIC blocks header Length, the length of the extension of assemblage circulation header and the mobile service circulation of the extension for the FIC block headers that version changes to produce Extension length.

According to an embodiment of the invention, the receiver that can be changed using corresponding secondary protocol version (or connect Receipts system) corresponding extended field can be handled, and can not connecing using tradition (routine) of corresponding secondary protocol version change Corresponding extended field can be skipped by using each corresponding length information by receiving device.For example, can receive in reception system In the case that corresponding secondary protocol version changes, the direction provided in corresponding extended field can be known.In addition, connecing Receipts system can perform operation according to the direction provided in corresponding extended field.

According to an embodiment of the invention, by being included in the FIC block reports of previous secondary protocol version FIC blocks respectively Insert added field to perform the secondary agreement in FIC blocks at ending, assemblage circulation header and the mobile service circulation of head Version changes.According to the embodiment of the present invention, in the case of any other, or when can not be by each in FIC block headers Extension length representing during the length of (or instruction) added field, or lose when the specific fields in FIC block payload (or Can not find) when, or when the definition for the bit number or corresponding field for distributing to corresponding field changes (or change), Update the master agreement version of corresponding FIC blocks.

Moreover, FIC blocks header represents whether the data of corresponding FIC blocks payload carry current M/H frames with signal Map information between interior assemblage and mobile service, or corresponding FIC blocks payload data whether carry it is next Map information between the assemblage and mobile service of M/H frame ins.In addition, FIC blocks header also represents to send current with signal The transport stream ID of the mobile service of FIC blocks quantity and the quantity by the assemblage transmitted by corresponding mobile service.

Therefore, therefore, FIC blocks header can include FIC_major_protocol_version fields, FIC_minor_ Protocol_version fields, FIC_chunk_header_extension_length fields, ensemble_loop_ Header_extension_length fields, M/H_service_loop_extension_length fields, current_ Next_indicator fields, transport_stream_id fields and num_ensembles fields.

FIC_major_protocol_version fields correspond to 2 bits of the main release level for representing FIC block grammers Unsigned integer field.The change of main release level will indicate the change of non-back compatible rank.Work as FIC_major_ When protocol_version fields update, the reception of the tradition (routine) of the previous key plate sheet of FIC block agreements can be handled Device will be avoided handling FIC blocks.

FIC_minor_protocol_version fields correspond to 3 bits of the subedition rank for representing FIC block grammers Unsigned integer field.When assuming that main release level keeps identical, the change of subedition rank will indicate back compatible rank Change.More specifically, when updating FIC_minor_protocol_version fields, identical key plate sheet can be handled The receivers of tradition (routine) of FIC block agreements can handle a part of FIC blocks.

FIC_chunk_header_extension_length fields correspond to the length of identification FIC block header extension bytes 3 bit unsigned integer fields of degree, update to generate the field by the secondary protocol version of corresponding FIC blocks.Herein, it will expand Byte additional (or increase) is opened up at the ending of corresponding FIC blocks header.

Ensemble_loop_header_extension_length fields correspond to identification assemblage header extension byte 3 bit unsigned integer fields of length, update to generate the field by the secondary protocol version of corresponding FIC blocks.Herein, will Extended byte additional (or increase) is at the ending that corresponding assemblage circulates header.

Moreover, M/H_service_loop_extension_length fields correspond to identification assemblage header extension byte Length 4 bit unsigned integer fields, update to generate the field by the secondary protocol versions of M/H service cycles.Herein, By extended byte additional (or increase) at the ending of corresponding M/H service cycles.

Current_next_indicator fields correspond to 1 bit indicator, wherein, when being set to " 1 ", it is indicated Corresponding FIC blocks are currently applicable.Alternatively, when current_next_indicator fields are set into " 0 ", Current_next_indicator fields indicate that corresponding FIC blocks will be applied to next M/H frames.Herein, when by current_ When next_indicator fields are set to " 0 ", transmitted with being set to the current_next_indicator fields of " 1 " The nearest version of FIC blocks will be current applicable.More specifically, set when by current_next_indicator fields When being set to " 1 ", this indicates that corresponding FIC blocks send the signaling data of current M/H frames.In addition, working as current_next_ When indicator fields are set to " 0 ", this indicates that corresponding FIC blocks send the signaling data of next M/H frames.When occur again During configuration, wherein, the map information between the assemblage and mobile service of current M/H frame ins is different from the assemblage of next M/H frame ins Map information between mobile service, is referred to as current M/H frames, and will reconfigure it by the M/H frames before reconfiguring M/H frames afterwards are referred to as next M/H frames.

Transport_stream_id fields correspond to 16 bit unsigned integer fields, and it is served as recognizing correspondence M/H broadcast mark.The value of corresponding transport_stream_id fields is by equal to including broadcasting in main ATSC Program Association Table (the PAT of mpeg 2 transport stream：Program association table) in transport_stream_ The value of id fields.

Num_ensembles fields correspond to 8 bit unsigned integer fields, and its instruction is believed by corresponding physical transfer The quantity for the M/H assemblages that road is carried.

Figure 10 is exemplified with agreement version when using FIC blocks grammer and protocol version structure according to the embodiment of the present invention This example is sexually revised.

Figure 10 illustrates structure include 2 assemblages (that is, assemblage 0 and assemblage 1).Herein, two are sent by assemblage 0 Mobile service, and a mobile service is sent by assemblage 1.At this moment, when the secondary protocol version of FIC blocks changes, FIC_ The value increase of minor_protocol_version fields, and indicate this increase.Moreover, passing through FIC block headers respectively FIC_chunk_header_extension_length fields, ensemble_loop_header_extension_length words Section, M/H_service_loop_extension_length fields represent to be increased by corresponding secondary protocol version with signal Plus FIC block headers extended byte, assemblage circulation header extended byte and mobile service circulation extended byte it is respective Length information.More specifically, each length information is represented with signal so that corresponding secondary protocol version can not be continued to use and changed Traditional receiver can skip corresponding extended byte.

In the case of Figure 10, the value of the FIC_minor_protocol_version fields of FIC blocks changes extremely from " 000 " “001”.Also, by FIC_chunk_header_extension_length fields, ensemble_loop_header_ Extension_length fields and M/H_service_loop_extension_length fields increase (or additional) extremely change Secondary protocol version FIC block headers.Now, when FIC blocks 1 byte of header extension, FIC_chunk_header_ Extension_length fields are marked as " 001 ".In this case, by extended field (that is, the FIC_ of 1 byte Chunk_header_extension_bytes fields) increase to the ends of FIC block headers.Moreover, traditional receiver is skipped Increase the extended field of 1 byte at the end of FIC block headers, without handling corresponding extended field.

In addition, when the assemblage in FIC blocks circulates 2 bytes of header extension, FIC_chunk_header_extension_ Length fields are marked as " 010 ".In this case, by extended field (that is, the Ensemble_loop_ of 2 bytes Header_extension_bytes fields) end of the circulation header of assemblage 0 and the end of the circulation header of assemblage 1 are increased to respectively Tail.Moreover, traditional receiver skip be increased respectively in assemblage 0 circulation header end at and assemblage 1 circulate header end The extended field of 2 bytes at place, the extended field without handling corresponding 2 bytes.

In addition, when 1 byte of mobile service cyclic extensions of FIC blocks, M/H_service_loop_extension_ Length fields are marked as " 001 ".In this case, by extended field (that is, the M/H_service_loop_ of 1 byte Extension_bytes fields) increase at the end that 2 mobile services being recycled by assemblage 0 are circulated and lead to respectively Cross at the end of 1 mobile service circulation of the cyclic transfer of assemblage 1.Also, traditional receiver, which is skipped to increase to respectively, to be passed through What 1 mobile service being recycled at the end for 2 mobile services circulation that assemblage 0 is recycled and by assemblage 1 was circulated The extended field of 1 byte at end, the extended field without handling corresponding 1 byte.

Figure 11 handles the exemplary of FIC blocks exemplified with when the secondary protocol version information change of FIC blocks as shown in Figure 10 Process.When FIC_minor_protocol_version field changes, the receiver of tradition (or, conventional) is (i.e., it is impossible to continue to use The receiver that secondary protocol version in corresponding FIC blocks changes) handle the field separated from extended field.Thereafter, it is traditional Receiver uses FIC_chunk_header_extension_length fields, ensemble_loop_header_ Extension_length fields, M/H_service_loop_extension_length fields, to skip corresponding extension word Section, without handling corresponding field.When the reception system changed using the corresponding secondary protocol version that can continue to use FIC blocks, respectively Individual length field is used to handle even corresponding extended field.

Exemplary syntax structures of the Figure 12 exemplified with the FIC block payload according to an embodiment of the invention.It is right In each corresponding assemblage of the num_ensembles fields in the FIC block headers with Fig. 9, FIC blocks payload includes each The configuration information of assemblage and on the information of the mobile service sent by each assemblage.FIC block payload is followed including assemblage Mobile service circulation under ring and assemblage circulation.FIC block payload allows a receiver to determine which assemblage passed through To send (or desired) mobile service of request.(by between ensemble_id fields and M/H_service_id fields Map to perform the processing).Thus, receiver can receive the RS frames for belonging to corresponding assemblage.

Therefore, the assemblage circulation of FIC block payload can include ensemble_id fields, ensemble_ Structure_major_version fields, ensemble_structure_minor_version fields, SLT_ Ensemble_indicator fields, GAT_ensemble_indicator fields, M/H_service_configuration_ Version fields and num_M/H_services fields, they are common repeat as num_ensembles field values more than it is secondary Number.Mobile service circulation can include multi_ensemble_service fields, M/H_service_status fields and SP_ Indicator fields, they are common repeat as num_M/H_services field values more than number of times.

Ensemble_id fields correspond to 8 bit unsigned integer fields, and it indicates unique mark of corresponding assemblage Symbol.For example, can be to the value in the range of ensemble_id field distributions " 0x00 " to " 0x7F ".Ensemble_id fields will Mobile service is carried out in groups (or association) with each assemblage.Herein, it is preferred that carried (or transmission) by TPC data Parade_id fields obtain the value of ensemble_id fields., will most if sending corresponding assemblage by main RS frames High significance bit is set to " 0 ", and by remaining low order be used as corresponding queue parade_id field values.Meanwhile, such as Fruit sends corresponding assemblage by auxiliary RS frames, then is set to highest significant position " 0 ", and remaining low order is used as The parade_id field values of corresponding queue.

Ensemble_major_protocol_version fields correspond to 2 bit unsigned integer fields, its expression pair The other version of main (specifically, corresponding RS frame structures and mobile service structure) for the assemblage structure answered.Herein, master agreement version Change will indicate the change of non-back compatible rank.

Ensemble_minor_protocol_version fields correspond to 3 bit unsigned integer fields, its expression pair The secondary version (specifically, each RS frame structure and each M/H traffic signalings channel) for the assemblage structure answered.Assuming that main revision level Do not keep constant, then the change of secondary protocol version level will indicate the change of back compatible rank.Herein, can have from FIC blocks Imitate and ensemble_structure_major_version fields and ensemble_structure_minor_ are omitted in load Version fields.

SLT_ensemble_indicator fields correspond to 1 bit indicator, wherein, when being set to " 1 ", it will indicate The bearer service label list (SLT) in the M/H traffic signaling channels of corresponding assemblage.

GAT_ensemble_indicator fields correspond to 1 bit indicator, wherein, when being set to " 1 ", it will indicate Guide is carried in the signaling flow of corresponding assemblage and accesses table (GAT).

M/H_service_configuration_version fields correspond to 5 bit fields, and it indicates corresponding M/H The version number of each M/H traffic signaling channel of assemblage.The value of M/H_service_configuration_version fields is " to 32 modulus ", and when changing any table carried in the M/H traffic signaling channels of corresponding assemblage, the word The value of section is incremented by (or increase) in units of 1.

Num_M/H_services fields correspond to 8 bit unsigned integer fields, and it represents to pass through corresponding M/H assemblages The quantity of the M/H business carried.For example, when the secondary protocol version of FIC blocks changes, and if extended field is increased to Assemblage circulates header, then increases extended field after num_M/H_services fields.

For example, being reported when the secondary protocol version in FIC block headers changes, and when extended field is increased into assemblage circulation During head, extended field increases after num_M/H_services fields are followed closely.According to another implementation of the invention, such as Fruit num_M/H_services fields are included in mobile service circulation, then will want increased extension word in assemblage circulation header Duan Zengjia is after M/H_service_configuration_version fields are followed closely.

The M/H_service_id fields of mobile service circulation correspond to 16 bit unsigned integer fields, and it recognizes correspondence M/H business.The value (or, number) of M/H_service_id fields is unique in movement (M/H) broadcast.When M/H business exists When having composition in multiple M/H assemblages, the set of the IP stream corresponding with the business in each assemblage will be considered as being used for signaling Single business, except that in FIC for corresponding business entry all have identical M/H_service_id words Segment value.Thus, identical M/H_service_id field values can be appeared in more than one num_ensembles circulations.And And, therefore, M/H_service_id field values will represent the business of all combinations, so as to keep M/H_service_id field values Uniqueness.

Multi_ensemble_service fields correspond to the field that 2 bits are calculated, and it identifies whether by more than one Individual M/H assemblages carry corresponding M/H business.Moreover, multi_ensemble_service fields identify whether only with passing through A part of M/H business that corresponding M/H assemblages are carried purposefully expresses M/H business.

M/H_service_status fields correspond to 2 bit enumerated fields, and it recognizes the state of corresponding M/H business. For example, the highest significant position of M/H_service_status fields indicates that corresponding M/H business is activation (when being set to " 1 " When) or inactive (when being set to " 0 ").In addition, least significant bit indicates whether corresponding M/H business is hiding It is (when being set to " 1 ") or no hiding (when being set to " 0 ").SP_indicator fields correspond to 1 bit field, its In, when being set to " 1 ", it indicates whether service protection is applied to needed for the important presentation for providing corresponding M/H business At least one composition.

For example, when the secondary protocol version of FIC blocks changes, and if extended field is increased to mobile service circulation, Then extended field is increased to after SP_indicator fields.

Moreover, FIC blocks payload can include FIC_chunk_stuffing () field.In order that the border of FIC blocks Keep aliging with last FIC section boundary in the FIC sections of FIC blocks are belonged to, FIC_chunk_stuffing () field Filling (stuffing) may reside in FIC blocks.By being left after whole FIC blocks payload is parsed before filling How many space come determine filling length.

Now, as shown in figure 13, according to the present invention transmission system (not shown) FIC blocks are divided into it is multiple FIC sections, from And by the FIC sections output of division to reception system in units of FIC sections.Each FIC sections of size is 37 bytes, and each The FIC section payload of the FIC sections of FIC section headers for including 2 bytes and 35 bytes.More specifically, as shown in Figure 13 (a), FIC Block includes FIC blocks header and FIC block payload, and shown in such as Figure 13 (b), FIC blocks are segmented in units of 35 bytes. Moreover, as shown in Figure 13 (c), FIC sections are configured to above to increase the FIC section headers of 2 bytes in each section of 35 byte units.

According to an embodiment of the invention, the length of FIC block payload is variable.Herein, the length of FIC blocks Change be determined by the quantity of the assemblage transmitted by corresponding used physical transmission channel and the movement being included in each assemblage The quantity of business.

Moreover, FIC blocks payload can include filling data.In this case, according to the embodiment of the present invention, Filling data is used for FIC blocks and last FIC section boundary alignment in the FIC sections of FIC blocks are belonged to.Therefore, by inciting somebody to action The length for filling data is minimized, it is possible to reduce FIC sections of unnecessary waste.

Herein, the quantity for the filling data inserted in FIC blocks can be calculated by using following equation 1.

Equation 1

Fill quantity=35-j of data byte

J=(5+ is inserted in the quantity of the signaling data byte in FIC block payload) is to 35 modulus

For example, when institute's header of increased 5 bytes in FIC blocks and the letter of payload being inserted in FIC blocks When making the total length of data equal to 205 byte, because j can include 5 in equation 1 equal to the payload of 30, FIC blocks The filling data of individual byte.Moreover, the length of the FIC block payload including filling data is equal to 210 bytes.Thereafter, will FIC blocks are divided into 6 FIC sections, are then sent to.Herein, segment number is sequentially assigned to 6 FIC sections divided from FIC blocks Each section.

In addition, as shown in figure 14, the present invention can send the FIC sections divided from single FIC blocks to single subframe, or The FIC sections of division can be sent at most individual subframe.If the situation behind as shown in figure 14 is like that divided FIC blocks And send to multiple subframes, even if when the quantity of the data sent by FIC blocks is more than the FIC sections sent by single subframe During quantity (such case corresponds to when performing multiple business with low-down bit rate), required signaling data can be with All it is transmitted by FIC blocks.

Figure 14 passes through the 4 FIC sections FIC blocks being transmitted exemplified with when the TNoG of corresponding mobile broadcast is equal to " 6 " Data an example.

More specifically, Figure 14 shows an example for being transmitted repeatedly FIC blocks twice.Reference picture 14, from All FIC sections that FIC blocks are divided are divided by 2 subframes (subframe 1 and subframe 2) to be transmitted, and from FIC blocks All FIC sections be only transmitted by one (subframe 1) of 2 subframes.More specifically, the present invention points out to lead to Single subframe is crossed to send multiple FIC blocks.In fig. 14, the content of 2 FIC blocks can be with mutually the same or can each other not Together.

Herein, the numbering of indicated FIC sections represents the numbering of the FIC sections in each FIC block in fig. 14, is not FIC segment numbers in each subframe.Therefore, it is possible to eliminate the subordinate relation between FIC blocks and subframe, so as to reduce FIC sections Excessive waste.

In addition, the present invention can increase empty FIC sections.No matter the transmission of the repetition of FIC blocks, and when in corresponding M/H frames In when needing to be filled, handled using empty FIC sections remaining FIC sections.For example, it is assumed that TNoG is equal to " 3 " and by FIC blocks It is divided into 2 FIC sections.Herein, when repeatedly sending FIC blocks by 5 subframes of single M/H frame ins, by 5 subframes A subframe (for example, with time sequencing be located at last tagmeme subframe) only send two FIC sections.In this case, One FIC sections of sky is distributed into corresponding subframe, so as to be transmitted.More specifically, FIC sections of the sky is used for FIC blocks Border and the border of M/H frames are aligned.Now, because empty FIC sections is not the FIC sections that are divided from FIC blocks, so will FIC segment numbers distribute to FIC sections of sky.

In the present invention, when single FIC blocks are divided into multiple FIC sections, and when divide after FIC sections be included in When in each data group of at least one subframe of M/H frame ins to be transmitted, with from the last subframe of corresponding M/H frame ins The opposite order-assigned started is corresponding FIC sections.According to the embodiment of the present invention, if there is empty FIC sections, then sky FIC Section is located in the subframe of M/H frame ins, so corresponding empty FIC section can be transmitted as last (or finally) section.

Figure 15 is exemplified with the data when the TNoG of corresponding mobile broadcast is equal to " 6 " by 8 FIC sections of transmission FIC blocks An example.In this case, the data volume sent by FIC blocks is more than the number of the FIC sections sent by single subframe Amount.Herein, as shown in figure 15, by sending the FIC sections divided from FIC blocks by 2 subframes, single FIC can be passed through Block sends all required signaling datas.Moreover, in this case, distributing to each FIC sections of numbering and corresponding to includes Each FIC sections of the numbering in FIC blocks.More specifically, even if being sent out when the quantity of FIC block number evidences is more than by single subframe During the quantity for the FIC segment datas sent, all FIC block numbers evidences can be also sent without leaving any data division not sent.

At this moment, in order that reception system can abandon empty FIC sections without handle it is corresponding empty FIC sections, it is desirable to be able to know The not other identification information of (or distinguish) FIC sections of sky.

According to one embodiment of the present invention, the present invention is made using the FIC_type fields in empty FIC sections header For for recognizing empty FIC sections identification information.In this embodiment, by the value of the FIC_type fields in empty FIC sections of header " 11 " are set to, to recognize corresponding empty FIC sections.More specifically, when the value quilt of the FIC_type fields in empty FIC sections of header When being set to " 11 " and being sent to reception system, reception system can abandon FIC_type field values and be arranged to " 11 " FIC sections of payload, without handling corresponding FIC sections of payload.Herein, value " 11 " is only to provide to promote and simplify The exemplary value of the understanding of the present invention., can be right as long as establishing being pre-configured between reception system and transmission system FIC_type fields, which are specified, any can recognize empty FIC sections value.Therefore, the present invention is not only limited to be showed in specification Example collection.In addition it is also possible to indicate that empty FIC sections identification letter can be recognized using another field in FIC sections of headers Breath.

Exemplary syntax structures of the Figure 16 exemplified with the FIC section headers according to an embodiment of the invention.Herein, FIC sections of headers can include FIC_type fields, error_indicator fields, FIC_segment_num fields and FIC_ Last_segment_num fields.Each field is described below.

FIC_type fields correspond to 2 bit fields, when being set to " 00 ", indicate corresponding FIC sections of carrying one Part FIC blocks.Alternatively, when FIC_type fields are set into " 11 ", FIC_type fields indicate that corresponding FIC sections is hair Send filling data empty FIC sections.Herein, its residual value retains for the use in future.

Error_indicator fields correspond to 1 bit field, its indicate transmission during in corresponding FIC sections whether Generation mistake.Herein, when errors occur, error_indicator fields are set to " 1 ".And ought be not present (or do not have Occur) mistake when, error_indicator fields are set to " 0 ".More specifically, during FIC sections of processing is configured, When there is the mistake do not repaired, error_indicator fields are set to " 1 ".More specifically, error_ Indicator fields enable reception system to recognize the presence or appearance of the mistake in corresponding FIC sections.

FIC_segment_num fields correspond to 4 bit unsigned integer fields, and it indicates corresponding FIC sections of numbering. For example, if corresponding FIC sections is first FIC sections of FIC blocks, the value of FIC_segment_num fields will be set as “0x0”.In addition, if corresponding FIC sections is second FIC sections of FIC blocks, then the value of FIC_segment_num fields will be by It is set to " 0x1 ".More specifically, FIC_segment_num fields with one will be with each additional FIC section in FIC blocks Incremented.Herein, if FIC blocks are divided into last FIC sections of FIC_ in 4 FIC sections, FIC blocks Segment_num field values will be indicated as " 0x3 ".

FIC_last_segment_num fields correspond to 4 bit unsigned integer fields, and it is indicated in complete FIC blocks Last FIC sections (that is, the FIC sections with highest FIC_segment_num field values) numbering.

In traditional method, (or distribution) FIC sections of volumes are sequentially designated for each FIC sections of a sub- frame in Number.Therefore, in this case, last FIC sections of numbering always matches (that is, last FIC sections of volume with TNoG Number always it is equal to TNoG).But, when using according to FIC numbering distribution methods of the invention, last FIC sections of numbering Not always match with TNoG.More specifically, last FIC sections of numbering can match with TNoG, or finally One FIC sections of numbering can not match with TNoG.TNoG represents distribution (or specifying) the extremely data group of single subframe Sum.For example, when TNoG is equal to " 6 ", and when FIC blocks are divided into 8 FIC sections, TNoG is equal to " 6 ", and finally One FIC segment number is " 8 ".

, can be by using the FIC_segment_num fields in FIC sections of headers according to another embodiment of the present invention Value it is empty FIC sections to recognize.More specifically, due to empty FIC sections distribution FIC segment number, not sending system by empty data Distribution is to empty FIC sections FIC_segment_num field values, and reception system can allow to make sky data distribution to FIC_ The FIC sections of segment_num field values are identified as FIC sections of sky.Herein, reception system and transmission system can be pre-set Data distribution to FIC_segment_num field values, to replace empty data.

As described above, FIC blocks are divided into it is multiple FIC sections, so as to be sent by single subframe or by many height Frame is sent.Furthermore, it is possible to send the FIC sections divided from single FIC blocks by single subframe, or single son can be passed through Frame sends the FIC sections divided from multiple single FIC blocks.Now, numbering and corresponding FIC of the distribution to each FIC sections Numbering (that is, FIC_seg_number values) in block is corresponding, without corresponding with the numbering in corresponding subframe.Moreover, can It is aligned with sending the FIC sections of borders with the border to M/H frames and FIC blocks of sky.Now, FIC segment numbers are not distributed to sky FIC sections.

As set forth above, it is possible to send a FIC block by multiple subframes, or send multiple by single subframe FIC blocks.However, according to the embodiment of the present invention, FIC sections being interleaved and being transmitted in units of subframe.

Figure 17 exemplified with as shown in Figure 13 to Figure 15 when sending single FIC blocks by multiple subframes or when logical When crossing the single multiple FIC blocks of subframe transmission, an example of the reception system of one or more FIC blocks is received and recovered.

More specifically, the data for each subframe are collected according to the signaling decoder 118 of the reception system of the present invention The FIC data in the signaling information region in group, to be interleaved in units of subframe to collected data.Thereafter, signaling The FIC sections of 118 pairs of decoder deinterleaving carry out RS decodings, so that by the data output by RS decodings to FIC processors 121. The FIC segment buffers interim storage of FIC processors 121 passes through the FIC sections that RS is decoded, and then exports the FIC sections of interim storage To FIC section resolvers.FIC section resolvers are extracted and analyze FIC sections of headers.Subsequently, based on the result of analysis, FIC section resolvers Collect the FIC sections for constituting single FIC blocks.Thereafter, FIC section resolvers remove the FIC sections report of the FIC sections collected by (or discarding) Head, so as to recover (or formation) single FIC blocks.

For example, FIC section resolvers utilize the FIC_segment_num fields and FIC_last_ in FIC sections of headers Segment_num fields constitute the FIC sections of a FIC block to collect.Then the FIC blocks of recovery are exported to FIC block resolvers. FIC block resolvers extract and analyzed the header for the FIC blocks being transfused to.Then, the result based on analysis, FIC block resolvers The signaling data being included in the payload of corresponding FIC blocks is extracted, so that the signaling data of extraction is exported to business pipe Manage device 122.

More specifically, the header for the FIC sections being then fed into by buffering is extracted and analyzed to FIC section resolvers.Thereafter, FIC section resolvers search (or positioning) FIC_segment_num field values are the FIC sections (that is, the including FIC block number evidences of " 0 " The FIC sections of one byte).Once FIC section resolvers located first FIC sections of FIC blocks, FIC section resolvers are sequentially received Collection is since first FIC sections to identical FIC_segment_num field values and FIC_last_segment_num words The data of the FIC sections of segment value.Thereafter, FIC section resolvers remove the FIC section headers of collected FIC sections, to constitute FIC blocks, from And export the FIC blocks of composition to FIC block resolvers.

For example, as shown in figure 17, it is assumed that the TNoG of corresponding mobile broadcast is equal to " 6 ", and FIC blocks are divided into 5 FIC sections to be transmitted.Reference picture 17, either transmits the FIC sections of FIC block or by 2 FIC blocks by 2 subframes FIC sections be sent to a subframe.It will, however, be evident that being deinterleaved processing in units of subframe.Moreover, collect from FIC_segment_num field values are that the FIC sections of " 0 " start to FIC_segment_num field values to be 5 of the FIC sections of " 4 " FIC sections.Thereafter, when removing each FIC sections of FIC section headers, a FIC block has been recovered.More specifically, when have collected When having 5 FIC sections of payload, recover (or composition) FIC block.Now, by corresponding empty FIC sections of header FIC_type fields identify FIC sections of sky.However, FIC sections of sky is dropped, without being used in FIC blocks recovery processing.

Figure 18 exemplified with when by 8 FIC sections to transmit FIC blocks when, and when the TNoG of corresponding mobile broadcast is equal to When " 6 ", reception system receives a FIC sections of examples to recover FIC blocks.

Moreover, in figure 18, although the FIC sections of a FIC block are transmitted by 2 subframes, it will be obvious that with son Frame is that unit is deinterleaved processing.Due to Figure 18 FIC blocks, to recover processing identical with the recovery processing of Figure 17 FIC blocks, can be with Reference is carried out to Figure 17, and in order to succinctly by specific descriptions of the omission to same section.

More specifically, collect since FIC_segment_num field values are the FIC sections of " 0 " to FIC_segment_ Num field values are 8 FIC sections of the FIC sections of " 7 ".Thereafter, when removing each FIC sections of FIC section headers, one has been recovered Individual FIC blocks.More specifically, when have collected 8 FIC sections of payload, (composition) FIC block is recovered.Now, lead to The FIC_type fields crossed in corresponding empty FIC sections of headers identify FIC sections of sky.However, FIC sections of sky is dropped, without in FIC Used in block recovery processing.

Simultaneously, it is assumed that multiple FIC blocks each with different protocol versions are transmitted by a M/H frame, and are connect Receipts system can handle all FIC blocks each with different protocol versions.Now, when being divided from multiple FIC blocks When each the FIC sections with different protocol versions are received normally without any mistake, reception system can be to each tool The multiple FIC blocks for having different protocol versions perform normal recover.If however, each there is different protocol versions There is the mistake caused by burst noise in multiple FIC blocks, then reception system can not be to each having different protocol versions Multiple FIC blocks perform normal recover.

For example, it is assumed that the FIC blocks that FIC blocks and master agreement version that master agreement version is " 00 " are " 01 " are sent extremely simultaneously One FIC (that is, one M/H frame).Also, as shown in Figure 19 (a), also assume that the mistake caused due to burst noise causes transmission Master agreement version is the section 7 of FIC sections 4 to FIC of the FIC blocks of " 00 " and the FIC sections 0 for sending the FIC blocks that master agreement version is " 01 " Do not received to FIC sections 3 by reception system.

In this case, reception system is also using the FIC_segment_num fields and FIC_ in FIC sections of headers Last_segment_num fields, using collecting since FIC_segment_num field values as the FIC of " 0 " sections to FIC_ Segment_num field values are 8 FIC sections of the FIC sections of " 7 ".Thereafter, as shown in Figure 19 (b), 8 FIC sections of removal is respective FIC sections of headers, so as to constitute a FIC block.In this case, due to FIC of the FIC_segment_num field values for " 0 " Duan Yucong master agreements version is corresponding for the FIC sections that the FIC blocks of " 00 " are divided, so reception system is by the FIC blocks constituted Master agreement version be identified as " 00 ", such as shown in Figure 19 (b).

However, in the case of the FIC blocks shown in Figure 19 (b), the section 3 of FIC sections 0 to FIC is " 00 " with master agreement version The FIC sections transmission data of FIC blocks are corresponding, and the section 7 of FIC sections 4 to FIC and FIC section of the master agreement version for the FIC blocks of " 01 " Transmit data corresponding.Therefore, when due to burst noise is lost in FIC sections when, reception system can will transmission have 2 kinds The set of the FIC sections of the FIC blocks of different protocol versions is identified as the FIC sections of FIC block of the transmission with single protocol version Set so that recover FIC blocks when produce problem.In addition, when being gone wrong as described above in FIC blocks recovery processing, Reception system, which cannot recognize that, is not appropriately carried out the recovery of FIC blocks.Therefore, reception system can obtain the mobile industry with being asked The corresponding RS frames of the assemblage of business, so that the problem of causing very serious.

In order to solve the above problems, the present invention transmits the protocol version of FIC blocks by each FIC sections of FIC section headers Information.According to the embodiment of the present invention, the protocol version information of the FIC blocks transmitted by FIC sections of headers and corresponding FIC At least one in the master agreement version information of block and secondary protocol version information is corresponding

Syntactic structures of the Figure 20 exemplified with the FIC section headers according to another embodiment of the present invention.Herein, by FIC_ Chunk_major_protocol_version fields increase to the syntactic structure of the FIC section headers shown in Figure 16 in addition.

More specifically, Figure 20 FIC sections header can include FIC_type fields, FIC_Chunk_major_ Protocol_version fields, error_indicator fields, FIC_segment_num fields and FIC_last_ Segment_num fields.In addition to FIC_Chunk_major_protocol_version fields, in remaining field and Figure 16 The field of description is identical.Therefore, for simplicity, the specific descriptions of identical content will be omitted in fig. 20.

According to an embodiment of the invention, FIC_Chunk_major_protocol_version fields correspond to 2 Bit field, it indicates the master agreement version of corresponding FIC blocks.More specifically, the FIC_Chunk_ in FIC sections of headers Major_protocol_version fields have and the FIC_major_protocol_version in corresponding FIC blocks header Field identical value.The description of the FIC block headers in Fig. 9 is referred to for the master agreement version of FIC block grammers.Therefore, it is The concise specific descriptions that will omit identical content herein.

Figure 21 is exemplified with the FIC sections received with FIC section headers as shown in figure 20 and an example of recovery FIC blocks. In this case, also assume that multiple FIC blocks (for example, 2 FIC blocks) are sent to a FIC (that is, one M/H frame), two Each master agreement version of FIC blocks is different from each other, and reception system can be handled each with different master agreement versions Two FIC blocks.

More specifically, as shown in Figure 21 (a), it is assumed that be for the FIC blocks and master agreement version of " 00 " by master agreement version The FIC blocks of " 01 " are sent to a FIC (that is, one M/H frame), and the mistake caused by burst noise simultaneously, are received System is not received by for sending master agreement version for the section 7 of FIC sections 4 to FIC of the FIC blocks of " 00 " and for sending master agreement Version is the section 3 of FIC sections 0 to FIC of the FIC blocks of " 01 ".

Now, reception system utilizes the FIC_segment_num fields in FIC sections of headers, FIC_last_segment_ Num fields and FIC_Chunk_major_protocol_version fields recover FIC blocks.

More specifically, due to originating the FIC_Chunk_major_protocol_version to FIC sections 3 from FIC sections 0 Field value with from FIC sections 4 originate to FIC sections 7 FIC_Chunk_major_protocol_version field values it is respectively different, Although FIC segment numbers are continuous, if FIC block protocol versions are different from each other, then data can not constitute single FIC blocks.

As shown in Figure 21 (b), collected according to the FIC processors 121 of the reception system of the present invention from FIC_segment_num Field value is that the FIC sections starting of " 0 " arrives 4 FIC sections of the FIC sections that FIC_segment_num field values are " 3 ".Thereafter, remove 4 FIC sections of respective FIC sections of headers, so as to constitute the FIC blocks that master agreement version is " 00 ".In addition, FIC processors 121 are collected Originated from the FIC sections that FIC_segment_num field values are " 4 " to the 4 of the FIC sections that FIC_segment_num field values are " 7 " It is individual FIC sections.Thereafter, 4 FIC sections of respective FIC sections of headers are removed, so as to constitute the FIC blocks that master agreement version is " 01 ".

Accordingly it is possible to prevent problems with：When due to burst noise is lost in FIC sections when, reception system can be by The set of the FIC sections of FIC block of the transmission with 2 kinds of different protocol versions is identified as FIC of the transmission with single protocol version The set of the FIC sections of block.

More specifically, by even distributing the protocol version information of corresponding FIC blocks in FIC sections of headers, even if connecing Receive multiple FICs section of the mixture corresponding from the FIC blocks with different protocol versions in single M/H frames, the present invention The FIC section corresponding with identical protocol version can also be only collected, so as to recover FIC blocks.

Now, when FIC blocks are resumed, as shown in figure 21, FIC blocks are not always completely recovered.For example, master agreement version is The FIC lost blocks of " 00 " are originated to FIC_segment_num fields from FIC_segment_num field values for the FIC sections of " 4 " It is worth 4 FIC sections of the FIC sections for " 7 ".In addition, master agreement version for " 01 " FIC lost blocks from FIC_segment_num Field value is that the FIC sections starting of " 1 " arrives 4 FIC sections of the FIC sections that FIC_segment_num field values are " 3 ".

Therefore, according to the embodiment of the present invention, FIC blocks are not resumed in this case.More specifically, receipts are worked as When having collected all FIC sections with identical master agreement version, and when the quantity of collected FIC sections is less than from corresponding During the quantity for the FIC sections that FIC blocks are divided, then corresponding FIC blocks are not resumed.

Collect FIC sections to recover one at this point it is possible to perform in units of single subframe or in units of single M/H frames The processing of FIC blocks.Because identical FIC blocks can be repeated, then transmitted in single subframe, and it is because identical FIC blocks can repeat, then transmitted in single M/H frame ins.In addition it is also possible to make a reservation for (or preassigned) quantity Subframe be unit or to perform collect FIC sections of processing using the M/H frames of predetermined (or preassigned) quantity as unit.

In addition, according to an embodiment of the invention, it is assumed that in single M/H frame ins while and depositing with another master agreement The FIC blocks of version, and reception system can handle two kinds of FIC blocks each with different master agreement versions.In this feelings Under condition, each FIC sections of current FIC segment numbers, the numbering of last FIC sections and master agreement version is checked, it is possible to collect With the FIC sections with the master agreement version identical master agreement version of reception system, so as to constitute FIC blocks.

Alternatively, when assuming that there is the FIC blocks with another master agreement version simultaneously in single M/H frames, and it is false If reception system can only handle one in two kinds of master agreement versions, from representing its accessible master agreement version with signal FIC sections recover FIC blocks.

Meanwhile, as described above, the present invention uses FIC blocks, to send the mapping between assemblage and mobile service in M/H frame ins (or configuration) information.Herein, when reconstructing, wherein, the mapping letter between the assemblage and mobile service of current M/H frame ins Breath is different from the map information between the assemblage and mobile service of next M/H frame ins, and the present invention can be before corresponding reconstruct Using at least one FIC block from M/H frames, to represent reflecting between M/H frame ins assemblage and mobile service with signal in advance Information (or performing signaling in advance) is penetrated, is reconstructed in the M/H frame ins.In the description of the invention, before reconstruct is occurred M/H frames are referred to as current M/H frames, and are referred to as next M/H frames in the M/H frames reconstructed after occurring.

In addition, according to the embodiment of the present invention, current M/H frame ins are alternately sent in signal table from single M/H frames Show the FIC blocks of the map information between assemblage and mobile service with representing assemblage and mobile service in next M/H frame ins with signal Between map information FIC blocks.Herein, according to the embodiment of the present invention, will be in next M/H frames according to time order and function order The interior FIC blocks that the map information between assemblage and mobile service is represented with signal, which are placed at current M/H frame ins and represented with signal, is After the FIC blocks of the comprehensive map information between mobile service, and assemblage and mobile service are represented with signal in current M/H frame ins Between map information FIC blocks after transmitted.More specifically, reception system receive first current M/H frame ins with Signal represents the FIC blocks of the map information between assemblage and mobile service, receives then later in next M/H frame ins with signal table Show the FIC blocks of the map information between assemblage and mobile service.

Now, when receiving FIC blocks and it being recovered, the FIC processors 121 of reception system utilize the FIC recovered Current_next_indicator fields in block header, to determine the signaling being included in the payload of each FIC block Map information that information is corresponded between the assemblage in current M/H frames and mobile service, also correspond in next M/H frames In assemblage and mobile service between map information.For simplicity, following by between the assemblage and mobile service in M/H frames Map information is also referred to as the assemblage configuration information of M/H frames.

Figure 22 exemplified with the exemplary situation reconstructed, wherein, the assemblage configuration informations of current M/H frames is different from next The assemblage configuration information of M/H frames.Reference picture 22, the part indicated by " ..., k-1, k, k+1, k+2, k+3 ... " represents each M/H Frame.Also, in this example, reconstruct occurs in (k+2) individual M/H frames.As shown in figure 22, the M/H frames before reconstructing Including two assemblages and seven TNoG.Also, the M/H frames after reconstructing include three assemblages and seven TNoG

As shown in figure 22, when the assemblage due to being sent to each M/H frame quantity, the mobile service for being sent to each assemblage Quantity and each subframe TNoG quantity change and when occurring reconstruct, the master agreement version information of FIC blocks and secondary assist Discuss version information and keep constant.However, the FIC_version field values in TPC data change.

Figure 22 shows that the FIC_version field values increase in the TPC data in (k+1) individual M/H frames (or is passed Increase) " 1 " is updated to the example of " 6 " afterwards, and show in the FIC block headers in (k+1) individual M/H frames Current_next_indicator field values are changed to the example of " 0 ".

Figure 23 exemplified with when being reconstructed in (k+2) individual M/H frames and when from (k+1) individual M/H frames alternately Transmit current M/H frames assemblage configuration information and next M/H frames assemblage configuration information when exemplary RS frames acquisition processing.

(k+1) individual M/H frames of reference picture 23, sent with signal current M/H frames assemblage configuration information FIC blocks earlier than The FIC blocks that the assemblage configuration information of next M/H frames is sent with signal are received, so as to be resumed.

Now, as shown in figure 23, the physical channel including required assemblage is entered when at the middle part of (k+1) individual M/H frames During row tuning, the assemblage configuration information of (k+2) individual M/H frames can be obtained from (k+1) individual M/H frames.More specifically, hair is worked as During raw reconstruct, it will be sent out in advance with the FIC blocks that signal transmission is carried out to the assemblage configuration information of the M/H frames reconstructed by performing M/H frames before giving corresponding reconstruct change the map information between the assemblage in mobile broadcast and mobile service, this hair It is bright promptly to obtain the assemblage for the M/H frames (that is, the M/H frames that there occurs corresponding reconstruct) that wherein there occurs corresponding reconstruct Configuration information.Moreover, by using the assemblage configuration information from (k+2) individual M/H frames acquired in (k+1) individual M/H frames, sheet Invention can obtain the RS frames for being sent to (k+2) individual M/H frames, so as to recover acquired RS frames completely.

Reference picture 24, except the tail portion in k-th of M/H frame performs tuning to the physical channel including required assemblage In addition, remaining tuning process is identical with the process step shown in Figure 23.Now, when reception system can not be received and about M/ During the part of 20% corresponding RS frames of H frames, it can recover whole by using RS-CRC decodings and SCCC decoding process RS frames.For example, it is assumed that the tail portion in k-th of M/H frame performs tuning to the physical channel including required assemblage, and from Intactly (or fully) obtains the signaling information of (k+1) individual M/H frames to first FIC block of (k+1) individual M/H frames.

In this case, when receiving first FIC block of (k+1) individual M/H frames, it can not yet receive and be sent to (k + 1) the RS frames of individual M/H frames.However, when the part not received about 20% equivalent to (k+1) individual M/H frames, by using RS-CRC decodings recover to be sent to the whole RS frames of (k+1) individual M/H frames with SCCC decoding process.In addition, even in (k+ 1) reconstructed in individual M/H frames, the present invention can use the letter from (k+2) individual M/H frames acquired in (k+1) individual M/H frames Information is made, intactly to recover the RS frames for being sent to (k+2) individual M/H frames.

As described above, the tuning point based on physical channel and the FIC block numbers in the M/H frames before reconstructing are according to knot Structure, the present invention can promptly obtain and recover RS frames, so as to provide a user required RS frames.

However, as described above, work as assemblage and the shifting for existing in single M/H frames and current M/H frame ins being transmitted with signal simultaneously Mapping between the FIC blocks of map information between dynamic business and assemblage and mobile service that next M/H frame ins are transmitted with signal During the FIC blocks of information, also occur in this case as FIC of the reception with different protocol versions in single M/H frames Occur during block it is identical the problem of.More specifically, from transmission with signal transmit current M/H frame ins assemblage and mobile service it Between map information FIC blocks FIC sections and transmission reflecting between the assemblage and mobile service of next M/H frame ins is transmitted with signal The FIC sections for penetrating the FIC blocks of information recover a FIC block, and mistake occurs among these.As described above, when the recovery in FIC blocks When being gone wrong in journey, the assemblage configuration information of next M/H frames can not be suitably obtained from the FIC blocks recovered.Therefore, also without Method suitably obtains and recovers to be sent to the RS frames of next M/H frames.

For example, being transmitted when with being received sequentially for mixing with signal between the assemblage and mobile service of current M/H frame ins Map information between the FIC sections of the FIC blocks of map information and assemblage and mobile service that next M/H frame ins are transmitted with signal During the FIC sections of FIC blocks, reception system can not determine that received corresponding FIC sections transmit current M/H frames with belonging to signal The FIC sections of the FIC blocks of map information between interior assemblage and mobile service are corresponding, or transmit next with belonging to signal The FIC sections of the FIC blocks of map information between the assemblage and mobile service of M/H frame ins are corresponding.Therefore, it may appear that above-mentioned asks Topic.

In addition, when mistake makes FIC sections of loss caused by due to burst noise, reception system be able to not can also determine to be received To corresponding FIC sections and the map information belonged between assemblage and mobile service that current M/H frame ins are transmitted with signal FIC The FIC sections of block are corresponding, or with belonging to the map information between assemblage and mobile service that next M/H frame ins are transmitted with signal FIC blocks FIC sections it is corresponding.Therefore, in this case, the problem of also occurring above-mentioned.

Similarly, when receiving TPC data and FIC sections as shown in figure 23, above mentioned problem can also occur.More specifically Say, as Figure 25 1. shown in, in the FIC that the map information between the assemblage and mobile service of next M/H frame ins is transmitted with signal In first FIC sections of block, the FIC_version field values in TPC data are added " 1 ".Correspondingly, such as Figure 25 2. institute Show, reception system can be exited from time slicing pattern, so as to collect FIC sections of (or, collection).

In addition, as Figure 25 3. shown in, reception system using collected FIC sections each FIC sections of header in FIC_ Segment_num fields and FIC_last_segment_num fields, only to collect the FIC sections for being constituted single FIC blocks, so that Each FIC sections is adjusted with the order of each FIC segment number.Thereafter, reception system removes header from each FIC section adjusted. Correspondingly, as Figure 25 4. shown in, constitute single FIC blocks.Then, reception system is from what the FIC blocks of composition obtained M/H frames Comprehensive configuration information.Then, as Figure 25 5. shown in, according to acquired assemblage configuration information, reception system entry time burst Pattern.

However, with reference to as Figure 25 3. shown in collection FIC sections, it is clear that the assemblage of current M/H frame ins is transmitted with signal The FIC sections of the FIC blocks of map information between mobile service and the assemblage and mobile service that next M/H frame ins are transmitted with signal Between map information FIC blocks FIC sections be mixing (simultaneous).More specifically, 3. Figure 25 shows not just Really collect FIC sections of example.Because reception system can not determine that corresponding FIC sections is to belong to transmit current M/ with signal The FIC sections of the FIC blocks of the assemblage configuration information of H frame ins, still fall within the assemblage configuration information that next M/H frame ins are transmitted with signal FIC blocks FIC sections.

In addition, when as Figure 25 4. shown in constitute FIC blocks when, reception system determines corresponding FIC blocks with signal Transmit the assemblage configuration information of next M/H frames.Match somebody with somebody however, FIC blocks include in the assemblage that current M/H frame ins are transmitted with signal Partial data in the FIC blocks of confidence breath.More specifically, Figure 25 4. show when FIC blocks include mistake (incorrect) An example being resumed during information.Accordingly, due to the assemblage configuration information correspondence acquired in the FIC blocks from incorrect recovery In incorrect information, so being sent to the RS frames of next M/H frames correctly will not be obtained and be recovered.

According to the embodiment of the present invention, in order to solve this problem, passed in the FIC section headers by each FIC sections When sending M/H frame identification informations, M/H frame identification informations inform that corresponding FIC sections is that the assemblage for transmitting current M/H frame ins with signal is matched somebody with somebody The FIC sections of the FIC blocks of confidence breath, or with the FIC sections of the FIC blocks of the assemblage configuration information of the next M/H frame ins of signal transmission.Root According to embodiments of the present invention, the M/H frames identification information transmitted by FIC sections of headers and current_next_indicator Field is corresponding.

Syntactic structures of the Figure 26 exemplified with the FIC section headers according to another embodiment of the present invention.More specifically, Current_next_indicator fields are additionally included in the syntactic structure of the FIC section headers shown in Figure 20.According to the present invention, Current_next_indicator fields are appointed as 1 bit.

More specifically, Figure 26 FIC sections header can include FIC_type fields, FIC_Chunk_major_ Protocol_version fields, current_next_indicator fields, error_indicator fields, FIC_ Segment_num fields and FIC_last_segment_num fields.Due to for FIC_type fields, error_ Indicator fields, the description of FIC_segment_num fields and FIC_last_segment_num fields are referred to figure 16, so in order to which simplicity will omit the specific descriptions of identical content.

FIC_Chunk_major_protocol_version fields correspond to 2 bit fields, and it indicates corresponding FIC blocks Master agreement version.Now, FIC_Chunk_major_protocol_version fields should with corresponding FIC blocks header FIC_major_protocol_version fields value it is identical.Due to retouching for the FIC block headers that are referred to shown in Fig. 9 State, for simplicity, by omit FIC block grammers master agreement version specific descriptions.

Current_next_indicator fields correspond to 1 bit indicator, wherein, when being set to " 1 ", it will indicate Corresponding FIC sections carry the FIC blocks suitable for current M/H frames a part.Alternatively, when by current_next_ When indicator fields are set to " 0 ", current_next_indicator fields will indicate FIC sections carry and be applied under A part for the corresponding FIC blocks of one M/H frames.In the previous case, to be set to the current_next_ of " 1 " Indicator field values will be currently available come the nearest version of the FIC blocks transmitted.

In addition, in signaling information region in data group, the TPC data then transmitted are together distributed with FIC data Including the parameter mainly used in physical layer block.Also, transmitted, reception system because TPC data are non-interleaved TPC data can be accessed in units of time slot.According to the embodiment of the present invention, by using making to include FIC_version The characteristic that the TPC data of field can be received in units of time slot, when updating FIC blocks, reception system can use TPC numbers According to FIC_version fields to determine the more new state of corresponding FIC blocks.Moreover, when the renewal for detecting corresponding FIC blocks During state, reception system is exited from time slicing pattern, so that FIC sections can be integrated (or combination).

An examples of the Figure 27 exemplified with the syntactic structure of TPC data.TPC data can include sub_frame_number Field, slot_number fields, parade_id fields, starting_group_number (SGN) field, number_of_ Groups (NoG) field, parade_repetition_cycle (PRC) field, RS_frame_mode fields, RS_code_ Mode_primary fields, RS_code_mode_secondary fields, SCCC_block_mode fields, SCCC_outer_ Code_mode_A fields, SCCC_outer_code_mode_B fields, SCCC_outer_code_mode_C fields, SCCC_ Outer_code_mode_D fields, FIC_version fields, parade_continuity_counter fields, TNoG fields With TPC_protocol_version fields.

Slot_number fields are the current time slots numberings in subframe, and it is to carry out M/H frame synchronization to be transmitted.Its Value will be in the range of 0 to 15.

Parade_id fields recognize the queue belonging to the group.The value of the field can be the value of any 7 bit.In M/H Each queue in transmission will have unique parade_id.In this case, it will be performed using ensemble_id Communications of the parade_id between physical layer and management level, wherein, by increasing by a bit to the parade_id left side come shape Into ensemble_id.If ensemble_id is to be directed to that the principal series transmitted by the queue is comprehensive, increased highest is effective Position (MSB) will be " 0 ".Otherwise, if ensemble_id is to be directed to the auxiliary assemblage transmitted by the queue, it is increased most High significance bit (MSB) will be " 1 ".

Starting_group_number (SGN) field is queue belonging to the group (group) (in order to be computed All preceding queues time-gap number after) first slot_number.

Number_of_groups (NoG) field is that the quantity of the group in subframe to the queue assignment belonging to the group subtracts 1, for example, NoG=0 represents that a group is allocated to the queue in subframe.The scope of NoG value will be from 0 to 7.Can root Distribution is calculated according to SGN and NoG to the timeslot number of corresponding queue.

Parade_repetition_cycle (PRC) field is the circulation of transmission queue to specify in units of M/H frames Time subtracts 1.

RS_frame_mode fields indicate that single queue carries single RS frames and still carries two RS frames.

RS code pattern of the RS_code_mode_primary fields indicator to main RS frames.

RS code pattern of the RS_code_mode_secondary fields indicator to auxiliary RS frames.

SCCC_block_mode fields indicate how to distribute the M/H blocks in data group to SCCC blocks.

SCCC_outer_code_mode_C fields indicate to be directed to region C SCCC external schema codes in data group.

SCCC_outer_code_mode_D fields indicate to be directed to region D SCCC external schema codes in data group.

FIC_version fields indicate the version of FIC data.More specifically, FIC_version fields represent FIC blocks The version of data structure.The value of the field will be arranged to all TPC data structures phases with being transmitted by a M/H frame Together, and whenever there is current_next_indicator fields in the subframe in transmission TPC data structures it is arranged to " 0 " FIC sections when, the value of the field will be incremented by 1.For example, when the numbering for the mobile service being included in assemblage 0 changes into 3 from 2, The value of FIC_version fields is constant.

Parade_continuity_counter fields are incremented to 0 to 15, and for being incremented by per (PRC+1) individual M/H frames 1.If for example, PRC=011, parade_continuity_counter field are incremented by for every four M/H frames.

TNoG fields indicate the sum of the data group transmitted in subframe.In other words, it is all queues in subframe NoG sum.Its value will be in the range of 0 to 16 (including 1 and 16).The use of TNoG fields both for current M/H frame informations or For signaling in advance.

TPC_protocol_version fields correspond to 5 bit unsigned integers, and represent corresponding TPC grammers knot The version of structure.2 highest significant positions are main release levels；Three least significant bits are subedition ranks, are read as：Key plate The change of this rank will indicate the change of non-back compatible rank.Assuming that main release level keeps constant, then subedition rank Change the change by back compatible rank is indicated.The initial value of the field will be " 11111 ".The version in the future of the standard each time During this change TPC structures, at least one bit will be altered to be formed the former original value of the field.Other versions It is worth the change for the grammer that can be used in future for reserved bit or for definition.First this change will be changed into " 00 " or " 000 ", so the field is with incremental for later change with other field identical modes.

However, the information being included in TPC data presented at this is only exemplary.Also, because this area is common Technical staff easily can be adjusted and change to the increase and deletion for being included in the information in TPC, therefore this not sent out The bright example being defined in illustrated by this paper.

Due to for each queue TPC data (except Sub_Frame_number fields and Slot_number fields with Value outside) does not change during M/H frames, therefore by belonging to all M/H groups of corresponding queue in M/H frames come repeatedly Transmit identical information.This allows very healthy and strong and reliably receives TPC data.Because Sub_Frame_number and Slot_ Number is incremental Counter Value, due to transferring the desired value of rule, therefore this Sub_Frame_number and Slot_ Number is also healthy and strong.

Figure 28 is exemplified with the FIC sections received each with FIC section headers as shown in figure 26 and with as shown in figure 27 The TPC data of structure, an example so as to recover FIC blocks.More specifically, as Figure 28 1. shown in, when TPC data structures FIC_version field values increase " 1 " when, reception system determines that the data structure of corresponding FIC blocks is updated.Then, such as Figure 28's is 2. shown, and reception system is exited from time slicing pattern, to collect FIC sections of (or collection).

Thereafter, as Figure 28 3. shown in, reception system using collected FIC sections each FIC sections of header in FIC_ Segment_num fields, FIC_last_segment_num fields and current_next_indicator fields, only to receive Collection constitutes the FIC sections of a FIC block.Then, reception system adjusts the FIC of each collection with the order of each FIC segment number Section.Then, as Figure 28 4. shown in, reception system removes each FIC sections of header, so as to constitute FIC blocks.Then, such as Figure 28 It is 5. shown, reception system obtains the assemblage configuration information of M/H frames from the FIC blocks of composition, with according to acquired assemblage configuration Information entry time fragmentation schema.

Figure 28 3. in the case of, when only collecting the FIC sections for constituting FIC block, can be reported in addition using FIC sections FIC_Chunk_major_protocol_version fields in head.More specifically, reception system can be used Segment_num fields, FIC_last_segment_num fields, current_next_indicator fields and FIC_ Chunk_major_protocol_version fields, with only collect with signal transmission it is corresponding with identical protocol version under The FIC sections of the FIC blocks of the assemblage configuration information of one (or, current) M/H frames.Then, reception system is with the suitable of each FIC segment number Sequence adjusts the FIC sections of each collection.Then, reception system removes each FIC sections of header, so as to constitute FIC blocks.Such as Figure 28 4. it is shown, can be only by the FIC of the assemblage configuration information with transmitting next M/H frames with signal when constituting FIC blocks as described above Block corresponding FIC sections constitute FIC blocks.

Therefore, reception system can prevent from belonging to the assemblage configuration information for transmitting current M/H frame ins with signal by collecting FIC blocks FIC sections and belong to the FIC sections of FIC blocks of assemblage configuration information that next M/H frame ins are transmitted with signal and construct list The problem of individual FIC blocks.More specifically, the present invention distributes M/H frame identification informations to each FIC sections of headers.Herein, M/H frames Identification information can recognize that the signaling information for the payload for being transferred into each FIC sections is the signaling information with current M/H frames It is corresponding or corresponding with the signaling information of next M/H frames.Thus, reception system without any mistake from FIC blocks Obtain the assemblage configuration information of next M/H frames.Correspondingly, reception system can correctly obtain and recover to be sent to next The RS frames of M/H frames.

Figure 29 and Figure 30 illustrate respectively the processing from FIC sections of recovery FIC blocks according to an embodiment of the invention Flow chart.Reference picture 29 and Figure 30, it is assumed that the FIC with identical FIC block master agreement versions is received in single M/H frames Block.Also assume that reception system can receive and handle the FIC blocks of FIC block protocol versions.

More specifically, when reception system is tuned to include the used physical transmission channel of the mobile service of user's selection (S501), reception system from be tuned to used physical transmission channel identification transmission user selection mobile service mobile broadcast letter Number (S502).Then, reception system finds out the subframe and distribute to the subframe that recognized mobile broadcasting is sent to Time slot (S503).

Then, collect by the data group (S504) received by the time slot of the subframe found in step 503.So Afterwards, the FIC data that are received in each signaling information region of collected data group are performed with PCCC decodings, using subframe as Unit by the PCCC FIC data decoded to performing deinterleaving, so as to perform the RS decodings as the inversely processing of transmission system (S505).It therefore, it can recover FIC sections for each subframe.Here, TPC not to being received in signaling information region Data are deinterleaved.However, performing the PCCC decodings and RS decodings as the inversely processing of transmission system.

After step 505 is performed, the section header of the FIC sections of first reception is analyzed, then, first is received In the FIC sections of FIC segment buffers that are stored in FIC processors 121 (S506).More specifically, to being included in first reception To FIC sections header in FIC_segment_num fields and FIC_last_segment_num fields parsed so that The quantity of the FIC sections divided by FIC segment numbers, the FIC segment numbers of last and from the FIC block corresponding with the FIC sections It is stored in FIC segment buffers.

Thereafter, next FIC sections of reception system capture, to analyze next FIC sections of the header captured, so as to check FIC Segment number (S507).In other words, by by being parsed to the FIC_segment_num fields in next FIC sections header, Reception system extracts corresponding FIC sections of FIC segment numbers.

Then, whether reception system is examined FIC sections and is had stored in FIC segment buffers (S508).The information can be from The FIC segment numbers (that is, FIC_segment_num fields) extracted in step 507 are known.

When confirming that corresponding FIC sections has stored in FIC segment buffers in step 508, (or deletion) is abandoned right The FIC sections answered and without storing (S509).However, ought confirm that corresponding FIC sections is not stored in FIC sections in step 508 When in buffer, corresponding FIC sections is stored in FIC segment buffers (S510).

After step 509 or step 510 is performed, reception system examine the FIC sections of FIC blocks whether all received and It is stored in FIC segment buffers (S511).Can be by the quantity and FIC_ of the FIC sections to being stored in FIC segment buffers The value of last_segment_num fields is compared to verify the information.

When all FIC sections that not FIC blocks are confirmed in step 511 are stored in FIC segment buffers, system is received System return to step 507, with repetition and next FIC sections of corresponding process step.

On the other hand, when all FIC sections of the confirmation FIC blocks in step 511 are stored in FIC segment buffers When, reception system is adjusted with the order of FIC segment numbers to the FIC sections being stored in FIC segment buffers, is then sequentially moved FIC sections of header (S512) unless each.So as to recover a FIC block (S513).

It is apparent to one skilled in the art that, under conditions of without departing from the spirit or scope of the present invention, Various modifications and variations can be made to the present invention.Therefore, appended claims and its equivalent are fallen into it is contemplated that covering In the range of these modifications and modified example of the invention.
