Abstract

Prior art methods of receiving, organizing, and implementing the data transmitted to mobile devices, such as ESG fragments, have a great impact on mobile device performance and battery lifetime. Furthermore, in order to keep server side and client side ESG fragments in synch, any change in content of ESG fragments needs to be indicated. Additionally, any change in how ESG fragments are distributed requires the client side to verify if all the fragments are still available and valid in any new distribution set up and if their content has not changed. Aspects of the invention provide a protocol for prioritizing the ESG fragments to ensure the end user of a destination device receives more pertinent ESG data in a timely manner. Other aspects of the invention minimize the number of updates required on a client side or destination device caused by the re-distribution of the ''unchanged'' ESG fragments into different carousels.

Description

The priority ordering of the ESG data in the radio network

The application requires the priority in the provisional application of the sequence number 60/663,066 of submission on March 18th, 2005.Its disclosure is all quoted as a reference at this.

Technical field

The present invention relates generally to communication network.More specifically, the present invention relates to the signalling of the data aggregate in the broadcast system.

Background technology

Generally speaking, electronic service guidebooks (ESG) makes terminal can pass on what service to can be used for the terminal use and how can visit described service.The ESG fragment is independent of existing ESG sheet (piece).Routinely, the ESG fragment comprises XML document, but they have contained clauses and subclauses such as the enormous amount of for example SDP (Session Description Protocol) description, text or image recently.Described ESG fragment is described the service of current available (or following) or one or several aspect of broadcast program.These aspects can comprise, for example: free textual description, timetable, geographical availability (geographicalavailability), price, purchasing method, style and such as the side information of preview image or montage.The data that comprise audio frequency, video or other type of ESG fragment can send by the various types of networks according to many different agreements.For example, the set of the network that data can be by being commonly called " internet " sends the agreement of the internet protocol suite of described network utilisation such as Internet Protocol (IP) and User Datagram Protoco (UDP) (UDP).Data usually send by the internet at unique user.Yet it can be known as multicast usually at one group of user.Under the situation of described data pin, it is called broadcasting to all users.

A kind of mode that data are broadcasted is to utilize IP data broadcasting (IPDC) network.IPDC is the combination of digital broadcasting and Internet Protocol.By this IP-based radio network, one or more service providers can provide and be included in report from a liner paper, radio and TV in interior dissimilar IP services.With the form of audio frequency, video and/or other types data with these IP service organizations in one or more Media Streams.In order to determine when and where these streams occur, and the user can be with reference to electronic service guidebooks (ESG).An example of using in digital video broadcasting (DVB) stream is electronic program guides (EPG).One type of DVB is handheld digital video broadcasting (DVB-H), a kind of technology of nearest exploitation, and it has increased ability and the service that can be used for such as the small hand-held formula equipment of mobile phone.Described DVB-H is designed to transmit the data of 10Mbps to battery powered terminal equipment.

Dvb transport stream transmits the Voice ﹠ Video and the data of compression to the user via third party's delivery network.Motion Picture Experts Group (MPEG) a kind ofly can be multiplexed to technology in the transport stream (TS) with other programs with video, audio frequency and the data of the coding in the single program by it.Described TS is the data flow of packing that comprises the grouping with regular length of header.Each element of program, Voice ﹠ Video, each leisure has in the grouping of unique packet identifier (PID) and is transported.In order to make receiver apparatus can in described TS, locate the different elements of specific program, provide the program specific information that is embedded among the described TS (PSI).In addition, additional service information (SI) promptly in accordance with one group of form of the proprietary part of MPEG (private section) grammer, is included among the described TS.This makes receiver apparatus can correctly handle the data that comprise among the described TS.

Yet, the present invention also is applicable to other, (comprise T/S-DMB such as for example T-DAB, DMB, T-DMB and DMB-T), traditional digital mobile broadcast system of ISDB-T, ATSC, Media Stream, and such as the non-traditional systems of 3GPP MBMS (multi-medium broadcast/group broadcast service) and 3GPP2BCMCS (broadcast/multicast service).

Because the transmission of described ESG is in the majority with image and other mass files, there is the demand that required network is transferred to described ESG fragment the terminal receiver effectively of crossing.Yet, previous system is transmit head before described ESG, because if before described header, send the container (container) that is used to transport ESG, thereby before described header arrives described information be inaccessible and exist and do not receive described header and cause the useless risk of data in the container, so this is very inefficient.Current effort concentrates on arrives several fragment association together, yet owing to lack the unique identifier of described fragment, effective header or index structure, the existence of perhaps required repeated parameter, these effort mostly are unsuccessful.

As mentioned above, can on such as the network of for example DVB-H, described ESG fragments for transport be arrived destination device by IPDC.Described then destination device must be determined the order of described ESG fragment once more and it is assembled into Useful Information.Receive, organize and realize that the method for the prior art of described ESG fragment all has very big influence to mobile device performance and battery life.In addition, keep synchronously, need any variation in the indication ESG segment contents in order to make server side and client's side ESG fragment.In addition, how through conveyer belt distribute any variation in the ESG fragment need described client's side checking in any new distribution is provided with all fragment whether still for available and effectively and their content whether be not changed.The result of current system and scheme is that unaltered ESG fragment and the fragment of having upgraded are carried out unnecessary distribution again together.At last, do not exist the agreement that is used for ESG fragment differentiation order of priority to receive more relevant ESG data in time with the described terminal use who guarantees destination device.

Therefore, it seems, have a kind of minimized demand of quantity that is distributed to the required renewal of caused client in the different conveyer belts or destination device by described " unaltered " ESG fragment again that makes in the prior art from above-mentioned situation.Also show to have described ESG fragment is carried out the demand that the system that most important ESG fragment is transmitted is in time guaranteed in priority ordering and realization.

Summary of the invention

The formation that each side of the present invention takes into account by container transmits the ESG fragment effectively to receiver.On this meaning, a container comprises at least one ESG fragment, but can comprise a plurality of fragments.Alternatively, fragment can be transported in more than one container.For example, described container is sent to described receiver, makes single ALC/LCT connection object corresponding to single container by utilizing asynchronous layer coding (ALC)/hierarchical coding transmission (LCT).Described fragment can be utilized by described receiver when receiving described entire container.Each side of the present invention is except that utilizing described fragment, and the type and the form that also are independent of described each fragment utilize a simple and open-ended header structure.In a further embodiment, compression is used on the entire container, comprise described fragment and any header, more further among the embodiment, other are sealed, for example the 3GPP metadata envelope can be transported in described container, and need not the unnecessary repetition of parameter such as for example version, effective time and sign.

Metadata among the 3GPP (third generation partner program) seal or other any type of sealing can comprise specific channel, specific program and/or specific channel bundle (channelbundles).The metadata of other types can comprise: set meal data (package data), purchase data, such as the operator's identity data and the technical data that are used to conclude the business, for example, address, agreement, can based on set meal/day, channel/minute, program/minute price data; Channel data, textual description, content supplier's label information/sign such as the user, classification and ranked data, such as style and father and mother's classification, channel SDP data, such as the description of using described service desired properties, for example, address, the proprietary expansion of Voice ﹠ Video form and bitrate information, starting and ending time, address, auxiliary data service synchronously; And program data, such as textual description to the user, starting and ending time, the reference of the interactive service relevant with program.This metadata can load or can automatically be carried out by operator.

Receive, tissue and implement art methods such as the data that will be sent to mobile device of ESG fragment, the performance and the battery life of mobile device had very big influence.In addition, keep synchronously, need any variation in the indication ESG segment contents in order to make server side and client's side ESG fragment.In addition, distribute any variation in the ESG fragment how and require described client's side checking, in any new distribution is provided with all fragment whether still for available and effectively and their content whether be not changed.Aspect of the present invention provides a kind of agreement, and it is used for that described ESG fragment is carried out priority ordering and in time receives more relevant ESG information with the terminal use who guarantees destination device.Other aspects of the present invention make, minimize the number in the required renewal of client's side or destination device that causes in the different conveyer belts by described " unaltered " ESG fragment is distributed to again.

Fig. 3 is the schematic diagram according to the example transport object of at least one aspect of the present invention.Generally speaking, single connection object 300 comprises container header 310 and container loads 320.By header 310 and load 320 are merged into single object 300, utilize and the relevant information in the location of each container in different connection objects, no longer need to reconfigure each header.In addition, no longer there is the problem that sends earlier as which that is occurred in the previous system.Container header 310 can comprise the configuration information about described header and/or described container loads 320.In one embodiment, described header 310 is encoded and is notified to receiver with the entry length with described header.

In described exemplary embodiment, header 310 has a plurality of ESG fragment descriptor entries 330 of the ESG fragment 340 in the sign container loads 320, so that described receiver can be determined the definite position and/or the length of the ESG fragment 340 that each is involved.For example, in one embodiment, field (field) is by providing, for example, deviant 550, starting and ending point etc., specify specific ESG in described container loads 120 from where.In other embodiments, can metadata 350 is relevant with independent ESG fragment 340, its be positioned at header 310, descriptor entry 330, ESG fragment 340 or its mix within or approaching with it.In one exemplary embodiment, the associating of 3GPP metadata envelope (metadata envelope) and ESG fragment 340 can replace or negate needs about the attaching metadata that is arranged in header 310 of specific ESG fragment.

Fig. 4 shows the method that sends a large amount of single object transmission, and wherein said transmission is according at least one aspect of the present invention.As shown in Figure 4, connection object of the present invention (TO) can, for example, FLUTE (file transfers on the one-way transmission) session, or be transported in the pure ALC session.In the example of Fig. 4, the ESG root channel data of statement such as IP address, port numbers and transport session identifier (TSI) in IP/MAC notification table (INT Table).The FLUTE session of described ESG root channel (root channel) comprises file delivery table (FDT) and one or more connection object (TO) of described session.These connection objects be included in dissimilar ESG with for the mapping between the access parameter of the different ESG sessions that send the ESG data therein.Described ESG can differ from one another, and for example is in the different language and/or has different codings or style.Described access parameter comprises IP address, port numbers, TSI, starting and ending time or the like.Described FLUTE session thereby statement how with described ESG data allocations in different sessions.The TO of the described FLUTE session of transporting this mapping (enum) data is described in the FDT of described FLUTE session.Described ESG mapping (enum) data can transmit in one or more TO.Can utilize the XML pattern, pure ASCII text, such as the structuring ASCII text of many parts MIME or MIME head, the binary file of enumeration type or carry out described mapping by other known modes in the prior art.Utilize the ESG session to transmit described ESG data in this example in one or more TO, described ESG session can be pure ALC session.Identical ESG data can be transmitted in one or more ESG sessions.In some embodiments of the invention, except the ALC session or replace described ALC session, can in one or more FLUTE sessions, transmit described ESG data or its part.

Fig. 5 is a block diagram, and it shows the example frame of electronic service guidebooks (ESG) fragment descriptor entries according at least one aspect of the present invention.Frame 500 shows the form of the protocol frame of header 310.Frame with descriptor entry 502A-D is exemplary example, and it comprises type and the feature of type field 505 with indication clauses and subclauses 330, and described type field can be expanded to allow to add new entry type.By a kind of entry type is input in this field 505, different information can be used for described receiver.In the example 502A-D of frame we predefine the certain metadata relevant with fragment.For example in 502B, described fields offset, initial, end and benchmark URI (BaseURI) are the metadata of corresponding fragment in the described load.Frame example 502C is then not relevant with the fragment of its expression with any metadata.

As mentioned above, described load can comprise to be sealed, it is arranged in metadata relevant with described fragment itself (all being included in described the sealing) or indication metadata in header, or described alternatively type provides the clauses and subclauses of the predefine parameter of the ESG fragment that is positioned at described load.In addition, shown in frame 502C, single descriptor entry can be configured to by a plurality of ESG fragments of its type specification, or even the different editions of identical ESG fragment.For example, frame 502A is marked as the Class1 clauses and subclauses, and comprises the information about described ESG fragment such as position, form, version information, unique identifier.For this point is described, frame 502 can provide, such as the extra information field about ESG fragment 340 of form 510, version 520 and unique identifier 530.In described exemplary embodiment, format fields 510 specifies whether ESG fragment 500 is text, video and/or picture.Yet, those skilled in the art will recognize that, format fields 510 in fact can specify any be comprised in ESG fragment 340 in the relevant information of type of medium.

Version field 520 can be included to allow to upgrade the ESG that had before received.For example, can automatically detect and carry out the version of the renewal of ESG, and can not be performed or can whether decide execution in its sole discretion by the user of described receiver by the expired ESG fragment of version field 520 appointments.Local service be available place this usually be useful.For example, when portable terminal when a region moves to another region, it is available that some services can keep, some can no longer be available then, and other services then can become available.Therefore, to follow in new region in described old region equally be effective to some in the described ESG object.In one embodiment, terminal can be discerned those effective ESG objects and can those no longer valid objects of store/cache in described new region.In another embodiment, terminal can receive and store from the ESG object of different frequency, IP platform and Virtual network operator and then these objects and the ESG group of objects from current network be synthesized unified ESG.

Alternatively, version field 520 can be connected with validity field 570 or be substituted by it.Whether can indicate the ESG fragment that received when version field 520 is latest edition or when being configured to determine whether that compatibility issue exists, validity field 570 can further be separated ESG fragment useless or lower priority.As shown in Figure 5, one or more validity field 570 can indicate relevant fragment in this effective period.Alternatively, validity can be based on the appearance of the hardware of described receiver, user-defined setting and/or other ESG.As an example, the existence of position that described node is loaded or benchmark URI whether in validity field 570 or in another field, can allow the checking of the ESG fragment that receives.In other embodiment, benchmark URI can so that described receiver can in conjunction with or substitute described ESG fragment and utilize the information that is positioned at described URI.

No matter unique identifier field 530 takes into account the identification of ESG fragment and information in the container header 310.Such information will be useful, for example, and when several ESG are received, carry out or no longer relevant with described header or when needing can to discern at large.Each of above information field 510,520,530 between other fields that are utilized, can comprise alternatively and fill field 540, to utilize the unsuitable alignment of byte rule compensation of described clauses and subclauses.For example, if the position of ESG fragment comprises the benchmark URI that enough bits are not provided for described clauses and subclauses,, can be used to fill necessary space to satisfy described bit demand then such as zero ascii character.As disclosed, each ESG fragment can be to be different from the bit rate coding of other ESG fragments.More further among the embodiment, can for example, in different information field 510,520,530, utilize different bit rates to the different parameters in the single ESG.

Can be by utilizing offset field 550 separately or combining the position that obtains the ESG fragment with entry length field 560, the skew of wherein said fragment can be measured from the starting point described header, the described load or other any points in the described connection object.Described field offset and length value can with bit, byte or any similarly quantitatively system measure.Just as discussed previously, utilize the field of different systems (i.e. 6 bits, 10 bits, 32 bits) can be coded in the identical descriptor entry.Each descriptor entry 500 has the fragment identification field 530 that identifies described ESG fragment uniquely.In described exemplary descriptor entry 500C, 500D, 500E, described benchmark URI is appended in the sign of the described fragment in the described load container, to create globally unique identifier.

Fig. 6 shows the exemplary containers according to a plurality of ESG fragments of having of at least one aspect of the present invention.Connection object 600 has the container header 610 before container loads 620, forms single connection object together.Header 610 comprises the coding section about header length 630.Header 610 can comprise signaling mechanism or transfer encoding mechanism alternatively, and it is configured to, and informs that with signal described connection object or its part are encoded or are compressed.In one embodiment, the LCT code-point is positioned at the beginning of header 610, can inform with signal, comprises that the whole transmission of described header is compressed.In other embodiment, reserved field can comprise with signal informs the code-point that described connection object 600 is encoded.As an example, GZIP can be used to this purpose; Yet, those skilled in the art will recognize that many other selections will realize the purpose compressed by this way.In having the embodiment of reserved field, extra information can be introduced into alternatively, and it is relevant to, for example, and described ESG, described header itself or extra compression or coded message.Container loads 620 comprises at least one ESG fragment 640, and it comprises the some or all of (see figure 3)s in the described fragment with metadata.In some instances, described fragment does not have metadata, and the metadata of any needs can find in the header 610 relevant with suitable descriptor entry on the contrary.Described connection object can be stored in the memory of transmitter, intermediate transmission node and/or various receivers.

Fig. 7 is a block diagram, and it shows the further exemplary frame of electronic service guidebooks (ESG) fragment descriptor entries according at least one aspect of the present invention.Frame 700,710,720,730 and 740 comprises the type field 750 of the type that is used to indicate received frame.As discussed above, type field 750 can be expanded to allow adding new entry type, and frame 700 shows simple ESG descriptor entry, and it provides the position of ESG fragment in the described load.In the illustrated embodiment, utilize the deviant of described ESG fragment to locate described fragment.

Frame 710,720 and 730 shows not relevant with any container loads various types of descriptor entrys.On the contrary, frame 710,720 and 730 can be used to make the ESG fragment that has received to come into force.In a further embodiment, shown in frame 740, described descriptor entry can comprise the statement for the benchmark URI of entire container.

More on the one hand, the present invention includes system and method, utilize it to determine, whether the container of up-to-date transmission is effective renewal of the container that before received, and need not to decode or handle information in the described container loads in addition.In at least one embodiment, transmitter is configured to many fragments are upgraded as individual unit.The container of described transmission can be configured to order further and be upgraded all object segmentation.Still, the present invention includes system and method, utilize its single instance of only requiring Container Type, to determine the mutual combination of the fragment in the possible example of same type more on the one hand.

Fig. 8 is the block diagram according to the containment system of the simplification of one embodiment of the present of invention, and described containment system is configured to the renewal of the fragment that is used for before having received.Described system is configured to determine that whether the container of up-to-date transmission is effectively to upgrade to need not to decode or read information in the described container loads in addition.Upgrade container 800 and generally include container header 810 and container loads 820.In described exemplary embodiment, header 810 comprises information relevant with the number of fragment in the load 820 and relevant deviant, yet, comprise the information relevant within the scope of the invention with header 810 and/or load 820.Described load comprises the data item 830,840 with fragment update.When described embodiment showed two data item, additional data item was expected and is sent independent data item.Each data item comprises the indication 850 of its type.

Described container can further be indicated the existence of payload header.For example, the data item of Class1 can be, and is relevant with predetermined fragment, the as directed binary envelope that has metadata in header.Type 2 can be indicated the 3GPP textual envelope relevant with different fragments.Therefore described metadata, is unfixed on transport layer.Except these examples, can also define other Container Types.

By the configuration of fragment and container instance and the update system of the described novelty of management realization." example of fragment " or " fragment instance " relate to the fragment with particular type and version, and wherein " example of container " or " container instance " relate to the container of the fragment instance that keeps specific.Fig. 9 is a block diagram, and it shows container and fragment management in the update system according to an embodiment of the invention.In described exemplary embodiment, file delivery table (FDT) 900 and 910 has been announced the instantiation of fragment packet.When receiving first container instance at first, described receiver determines clip types in each Container Type by it.All different vessels examples of same type use identical signature, and for example FDT content-position (Content-Location), but use different connection object identifiers (TOI).In described exemplary embodiment, FDT 900 has TOI=5 and FDT 910 has TOI=6, thereby indicates different container instances, yet described content type (Content-Type) and content-position remain unchanged.Two different container instances can be used different codings, and promptly they have different content (Content) type.For example, the container of the fragment B of the Segment A of the container of Segment A that keeps version A1 and the fragment B of version B1 and a maintenance version A2 and version B2 has identical Container Type.In addition, one keeps the container of Segment A (no matter its version why) will have and the visibly different Container Type of container that keeps (any version) Segment A, B and C.Additional optional field such as content-coding, depends on the preference of described transmitter, also the state that can remain unchanged.For example, if utilize text meta-data, can utilize, for example, other known mechanism are encoded to entire container in GZip or the prior art.Alternatively, have only part to be encoded.

The container coding can be stated by different mechanism with forward error correction (FEC).For example, the FDT parameter can be stated described encoding mechanism.In one embodiment, be used for stating described coding and FEC by making of LCT expansion.Described container is encoded so that described receiver can be determined, whether described container need not visit or read described container in addition decoded with handling.Figure 10 is a block diagram, and it shows the container that carries out according to one embodiment of the present of invention and upgrades.In described giving an example, FDT1010 has TOI=1 and corresponding to the type A container 1020 with example A1, wherein example A1 can comprise for example fragment 1: example 4 and fragment 2: example 3.FDT 1010 and relevant container 1020 are received in terminal, and it is processed or refusal at this.File delivery table 1030 is represented the renewal to FDT1010, and is received after receiving FDT 1010.FDT is still corresponding to type A container 1040, yet it comprises the example A2 of alternate example A1, and can comprise that such as for example, fragment 1: example 4 is constant, and fragment 2: example 3 becomes the variation of example 5.In case receive, described terminal determines that example A2 comprises one or more fragment updates with respect to example A1.Described terminal can determine further that A2 comprises the fragment with the A1 same type.In one embodiment, described terminal determines further based on all factors whether A2 should be implemented.

When about comprising when realizing that specifically having described for example of current preference pattern of the present invention is of the present invention, those skilled in the art will notice, have the many modification and the displacement of the said system and the technology that fall into the spirit and scope of the present invention of advocating as claims.Generally speaking, electronic service guidebooks (ESG) makes terminal what service of can communicating by letter can be used for the terminal use and how could visit described service.The ESG fragment is self-existent of ESG.Routinely, the ESG fragment comprises XML document, but they have been contained such as for example recently, the clauses and subclauses of the enormous amount of SDP (Session Description Protocol) description, text or image.Described ESG fragment is described the service of current available (or following) or one or several aspect of broadcast program.These aspects can comprise, for example: free textual description, timetable, geographical availability, price, purchasing method, style and such as the side information of preview image or montage.

The further embodiment of the present invention relates to broadcasting and upgrades described ESG fragment.Just as discussed previously, a kind of mode that data are broadcasted is to utilize IP data broadcasting (IPDC) network.IPDC is the combination of digital broadcasting and IP agreement.By this IP-based radio network, one or more service providers can provide and be included in report from a liner paper, radio broadcasting and TV in interior dissimilar IP service.With the mode of the form of audio frequency, video and/or other types data with these IP service organizations in one or more Media Streams.In order to determine when and where these streams occur, and the user can be with reference to electronic service guidebooks (ESG).An example of using in digital video broadcasting (DVB) stream is electronic program guides (EPG).One type of DVB is handheld digital video broadcasting (DVB-H), a kind of technology of nearest exploitation, and it has increased ability and the service that can be used for such as the small hand-held formula equipment of mobile phone.Described DVB-H is designed to transmit the data of 10Mbps to battery powered terminal equipment.

Figure 11 shows an embodiment of the improvement system that arranges the ESG fragments for transport.By many such as for example T-DAB, T/S-DMB, ISDB-T, the digital mobile broadcast system of ATSC, Media Stream and such as unconventional system of 3GPP MBMS (multi-medium broadcast/group broadcast service) and 3GPP2BCMCS (broadcast/multicast service) carries out described transmission.Receive, organize and realize that the method for the prior art of described ESG fragment causes the performance of mobile device and the adverse effect of efficient and battery life.In addition, keep synchronously any variation in the content of needs indication ESG fragment in order to make server end and client ESG fragment.In addition, how through any variation in the conveyer belt distribution ESG fragment need described client bring in checking in any new distribution is provided with all fragment whether still for available and effectively and their content whether be not changed.The result of current system and solution is that unaltered ESG fragment is carried out unnecessary distribution again with the fragment of having upgraded.At last, lacking one is used for described ESG fragment is carried out priority ordering in time receives more relevant ESG data with the terminal use who guarantees destination device agreement.

As shown in Figure 11, the ESG arrangement of fragments is become a series of repetition " conveyer belt " so that described fragment is transferred to client's side or destination device from server side.For example, a host-host protocol, the file transfers on the one-way transmission (" FLUTE ") on one-way system be suitable for wireless and the mode of putting multiple spot (broadcasting or multicast) system with the ESG fragments for transport to receiver.Figure 11 shows one embodiment of the present of invention, and can carry out priority ordering to information by utilization in the arrangement of this ESG fragment and carry out, described information description, the time frame of for example described ESG fragment and sub-time frame (sub-time frame).

As shown in Figure 11, the described arrangement of ESG fragment can be carried out with the information of prioritization by utilizing, described information description for example, the time frame of described ESG fragment and sub-time frame.The figure shows two the ESG series of carousels (1105,1125) that are arranged on described server side.Arranged and united described series of carousels 1105,1125 by first order precedence portion ground.In exemplary embodiment, described first order priority is determined by the time descriptor relevant with described serial 1105,1125.For example, series 1105 comprises the conveyer belt with ESG fragment relevant with " the 1st day ", and series 1125 comprises the conveyer belt with ESG fragment relevant with " the 2nd day " or " the 3rd day ".Therefore, series 1105 can have first order priority=1 and serial 1125 and have first order priority=2.

When the described series in the described exemplary embodiment comprises information on the three, it will be understood by those skilled in the art that the ESG fragment can be used for the longer period in other embodiments, such as the TV program list information.In these embodiments, can wish a plurality of series of carousels, each has different first order priority.More further among the embodiment, described time frame (exemplary first order priority) can include only the part of the ESG fragment that can be used for broadcasting or distribute.This will be especially favourable when may not have memory or bandwidth to broadcast with the mobile device of the transmission that receives a large amount of ESG fragments.

In addition, be appreciated that usually the ESG fragment in conveyer belt is few more, can be more quickly the content of described conveyer belt be sent to terminal use or equipment.In described exemplary embodiment, series (series) 1105 comprises " fast conveyer belt ", because they comprise less ESG fragment, they can be transmitted away with the shorter period by the conveyer belt slower with respect to (described below) therein.For example, each conveyer belt in the series 1105 comprises and 8 hours relevant ESG fragments of programme information (programminginformation), yet slower conveyer belt in the series 1125 is as described below, comprises the ESG fragment of 24 hours programme informations.Therefore, in other embodiments, can completely or partially determine a priority value by the length of the ESG fragment in the conveyer belt.It will be understood by those skilled in the art that described first order priority (and extra priority) can be based on a plurality of factors of the information that more may need or utilize such as for example terminal use.

In addition, as shown in FIG., series 1105 comprises each FLUTE session, and it has comprised conveyer belt 1110,1115 and 1120.In described exemplary embodiment, each all comprises a conveyer belt (therefore can be hereinafter referred to as conveyer belt 1110,1115 and 1120) described FLUTE session, yet, in other enforcement, in each FLUTE session, can comprise a plurality of conveyer belts.Arrange described each FLUTE session (conveyer belt) 1110,1115,1120 by second level priority.In described exemplary embodiment, described second level priority value is based on the time descriptor relevant with described conveyer belt or FLUTE session.As shown in FIG., conveyer belt 1110 is marked as " fast conveyer belt #1 " and describes the 1st day first 8 hours.Therefore, conveyer belt 1110 is assigned with one than " fast conveyer belt #2 " (1115) higher priority, and described " fast conveyer belt #2 " is when describing same day 8-16.Similarly, session 1115 is assigned with a ratio and comprises " fast conveyer belt 3# " (session 1120) higher priority with last 8 hours of the 1st day relevant ESG fragments.

FLUTE session collection 1125 comprises session (conveyer belt) 1130,1135,1140.As explained above, owing to have first order priority=2, because the ESG fragment in the conveyer belt 1130,1135,1140 comprises the ESG fragment of time frame subsequently, session series 1125 sends after being arranged on the conveyer belt of session series 1105, or compares with it and to have lower priority.The same with the session in the series 1105, by each conveyer belt of second level priority arrangement series 1125.For example, conveyer belt 1130 comprises and relevant ESG information on the 2nd, and conveyer belt 1135 comprises and relevant ESG information on the 3rd.Explain in more detail that as following the use of distinguishing priority allows specific conveyer belt is upgraded and need not to upgrade all conveyer belts.

Figure 12 shows one embodiment of the present of invention, wherein shows the renewal of described conveyer belt.An announcement carousel 1205 is sent to terminal use or equipment.Announcement carousel 1205 provides the information of any variation in the described conveyer belt to described terminal use or equipment.In described exemplary embodiment, described announcement carousel comprises that a series of Session Description Protocols (SDP) are to indicate the variation in the described conveyer belt.For example, the SDP#1 indication in the announcement carousel 1205, optional static objects carousel 1210 is followed in described announcement carousel back.Described static objects carousel is described nature and is the object of " static state ", and therefore unlikelyly is updated in the period of expansion or changes.This exemplary object can comprise, for example ordering information, sign or main introductory instruction.

Figure 12 shows the renewal such as those conveyer belts in Figure 11 according to 8 hour period in the past.Announcement carousel 1205 is provided to indicate conveyer belt 1215 (conveyer belt 1110 among Figure 11) no longer relevant (see SDP#2, it is available indicating different versions).For example, conveyer belt 1215 had before provided and had comprised the ESG fragment that is used for ongoing 8 hours information, no longer relevant through described information after the described specific period.Conveyer belt 1220, it comprises that the appointment based on its first and second grades of priority values becomes the highest priority about 8 hours ESG fragment next.Similarly, conveyer belt 1225 becomes the second preferential conveyer belt in the series 1105 subsequently.Because described exemplary embodiment can be announced three " soon " conveyer belts (the short conveyer belt that promptly comprises 8 hours programme informations on given date), according to removing of conveyer belt 1215, a new conveyer belt can be loaded in " bottom " position of the conveyer belt in the described series.For example, described new conveyer belt can have first order priority=1, second level priority=3.

In one embodiment, the conveyer belt that is currently located in another series is loaded, and for example, has the conveyer belt of lower first order priority.In such embodiments, the conveyer belt (i.e. series 1125) with ESG fragment of the information that comprises another day can be loaded into " bottom " position of series 1105.In described exemplary embodiment, the conveyer belt (1130, have first order priority=2) with different first order priority is divided into a plurality of independent conveyer belts, and at least one of the conveyer belt of wherein said up-to-date establishment is reassigned to be " soon ".In described exemplary embodiment, create conveyer belt 1230 and 1240 from conveyer belt 1130.Before, conveyer belt 1130 had been a slow conveyer belt (first order priority=2), and it comprises the ESG fragment that has with the 2nd day whole 24 hours relevant information.New conveyer belt 1230 comprises and first 8 hours of the 2nd day relevant ESG fragments.Because 1230 of conveyer belts have the ESG fragment corresponding to 8 hours programs, described conveyer belt is reassigned to be " soon " and is re-classified as has first order priority=1.Conveyer belt 1230 is placed on " bottom " position (under conveyer belt 1220 and 1225) of described " soon " conveyer belt then.Because conveyer belt 1230 has the ESG fragment of the information that is included in conveyer belt 1220 and 1225 time period afterwards, so it is placed on described bottom position.Therefore, conveyer belt 1230 is assigned to second level priority=3.

In described exemplary embodiment, 1130 of conveyer belts from remaining ESG fragment be retained in and have first order priority=2, in " slowly " conveyer belt 1235 of second level priority=1.Conveyer belt 1235 back then are conveyer belt 1240 and 1245, and it has the ESG fragment that comprises the information that relates to farther period program.For example, conveyer belt 1245 comprises 24 hours ESG fragment (first order priority=2 for the 3rd day, and conveyer belt 1250 comprises first 8 hours the ESG fragment (first order priority=2, second level priority=3) for the 4th day second level priority=2).When the relevant period through out-of-date, the ESG fragment of describing those periods be have nothing to do and therefore no longer be sent out.Therefore, when bandwidth to extra " soon " but conveyer belt become the time spent, can be dispensed in littler " soon " conveyer belt from the ESG fragment of big " slowly " conveyer belt.Equally, comprise that described user maybe needs the conveyer belt of the ESG fragment utilized probably, can be assigned with first higher or a second level priority.

Shown in preceding figure, no longer need to stride across conveyer belt and rearrange the ESG fragment to improve their transmission priority separately.On the contrary, the content of conveyer belt can be determined described conveyer belt is transferred to higher or lower priority.Therefore, terminal use or equipment can based on described first or second level priority read each FLUTE session or conveyer belt.

Figure 13 shows an example system of the present invention that is used for as ESG conveyer belt as described in the performed renewal of Figure 12.The set 1305 of computer-readable medium stores ESG data.The time frame that relates to by described ESG data is arranged the set 1305 of described exemplary ESG data.For example, ESG data 1310 comprise the conveyer belt that relates to about the electronic service guidebooks information of " the 1st day ".ESG data 1315 comprise the conveyer belt that relates to about the electronic service guidebooks information of " the 2nd day ".Therefore, ESG data 1310 can the value of being considered to have be that 1 first order priority and ESG data 1315 can the value of being considered to have be 2 first order priority.Therefore, all conveyer belts in the ESG data 1310 can be by prioritization on ESG data 1315.Yet in one embodiment, the ESG data with different first order priority values may be downloaded simultaneously or be visited.In such an embodiment, can provide bigger bandwidth to transmit for the data of higher priority.A plurality of extra ESG data, such as ESG data 1320 and 1322, it relates separately to illustrative " the 3rd day " and " the 4th day ", also can be accommodated in the set 1305 of data.

Also each of exemplary ESG data set 1310,1315,1320,1322 is carried out priority ordering according to second level priority value.Seen in described figure, described second level priority value can be determined in each ESG data 1310,1315,1320,1322 order at the conveyer belt of transmission.For example, can be from having comprised the second level priority value that the information instruction relevant with related time period of programme information the ESG fragment of encapsulation obtains described distribution.Note ESG data 1310, for example, hour 0-8 is endowed the priority on hour 8-16, and it is endowed the priority on hour 16-24 successively.Be used for distributing the instruction of described first and second grades of priority values can be positioned at any computer-readable medium, described medium has the computer-readable instruction that is used to carry out required step, such as controller 1325.

Controller 1325 can also be created announcement carousel 1330, and wherein said announcement carousel 1325 comprises the precedence information (seeing Figure 12) of described ESG conveyer belt.As mentioned above, described controller can be created a static objects carousel 1335 alternatively.Controller 1325 distributes one than the higher priority of described ESG conveyer belt in the ESG data 1310,1315,1320,1322 can further for described static objects carousel 1335, yet, give priority on all ESG conveyer belts in other embodiments, can be not for static objects carousel 1335.

In described exemplary embodiment, transmit described conveyer belt according to described conveyer belt first and second grades value separately as seen in Fig..For example, by conveyer belt 1340,1345 and 1350 findings, utilize higher priority transmission ESG DS 1310 (having the highest first order priority), wherein, when determining the priority of the described conveyer belt of transmission, can consider the value of described second level priority for each conveyer belt 1340,1345 and 1350.This arrangement makes the bandwidth of the improvement system be used to upgrade described conveyer belt and the less renewal of being devoted to described ESG fragment become possibility.

In one embodiment, when a conveyer belt was expired, new announcement carousel was sent out, and indicated described expired conveyer belt no longer to be sent out.For example, the 1st day 0-8 hour over and done with after, such as the announcement carousel of announcement carousel 1330, will be sent out with indication conveyer belt 1340 and no longer be sent out.Described conveyer belt with identical first order priority value, be rearranged such as conveyer belt 1345 and 1350 second level priority values based on its distribution, the content that wherein has been in the conveyer belt 1345,1350 in the described series is not changed, thereby does not need the renewal of the ESG fragment of the packaged conveyer belt 1345,1350 of terminal use or equipment inspection.Once more, other standard can be used to select conveyer belt receiving higher first order priority, and such as for example, comprising more may be by the conveyer belt of the ESG fragment of described terminal use or equipment utilization.Described reallocation can be sent to described terminal use or equipment by announcement carousel such as announcement carousel 1330.

The conveyer belt of the first order priority value that the conveyer belt that has and remove 1340 is different can be reallocated with the identical first order preferred value of the conveyer belt that has and remove 1340.In described exemplary embodiment, conveyer belt with the highest second level priority value has been broken down in conveyer belt 1355 and 1360, wherein conveyer belt 1355 is " soon " conveyer belt, it comprises 8 hours programs and has first order priority=1, second level priority=2, and conveyer belt 1360 is " slowly " conveyer belt, and it comprises " the 2nd day " remaining 16 hours and has first order priority=2, second level priority=1.Although the information of " the 2nd day " is divided in two conveyer belts now, described ESG fragment keeps identical order, has therefore got rid of the necessity that rearranges described ESG information and check its validity in terminal one side (terminal use or equipment).Therefore, in described exemplary embodiment, can receive by controller 1325 and upgrade 1375.Described controller carries out priority ordering to described renewal also can be with described ESG storage in ESG data set 1305.As discussed previously, controller 1325 can be arranged announcement carousel 1330 and ESG conveyer belt 1345-1370, being distributed to terminal use or equipment, and need not to rearrange each ESG fragment in the conveyer belt to improve its transmission priority separately.On the contrary, the content of conveyer belt can be determined described conveyer belt is transferred to higher or lower priority.Therefore, terminal use or equipment can read described each FLUTE session or conveyer belt based on first and second grades of priority.
