Description
The present invention be on December 2nd, 2004 attorney docket that submit to, that assigned be the continuation application of common pending application 004770.00311, " Enhanced Electronic Service Guide Container (enhanced electron service service guide container) " by name, be incorporated into this for your guidance at the full content of first to file.
Technical field
The present invention relates generally to communication network.More particularly, the signal that the present invention relates to the data aggregate in the broadcast system transmits.
Background technology
Usually, electronic service guide (Electronic Service Guide ESG) makes terminal can pass on the terminal use and how to visit described service with which service.The ESG fragment be ESG independently have a part.Typically, the EGS fragment comprises XML document, but they have comprised large quantities of projects, for example SDP (Session Description Protocol) description, text or image recently.The ESG fragment is described current (or following) available service or one or several aspect of broadcast program.Described aspect for example can comprise: free textual description, schedule, geographical availability, price, purchasing method, type, and supplemental information---for example preview picture or montage.The data that include audio frequency, video and other type of ESG fragment can send by various types of network based multiple different agreements.For example, agreement (for example Internet protocol (IP) and User Datagram Protoco (UDP) (UDP)) that can the internet usage protocol suite sends data by the collection of network that is commonly called " the Internet ".Usually send data by the Internet that is addressed to unique user.Yet data can be addressed to one group of user, are commonly referred to multicast.Be addressed in data under all users' the situation, this is called as broadcasting.
A kind of mode of broadcast data is to use IP data broadcasting (IPDC) network.IPDC is the combination of digital broadcasting and Internet protocol.By so IP-based radio network, one or more providers can provide dissimilar IP services, are included in report from a liner periodical, radio broadcasting, TV.These IP services are organized as one or more Media Streams with the form of the data of audio frequency, video and/or other type.In order to determine when these streams where occur, the user is with reference to electronic service guide (ESG).An example that is used for digital video broadcasting (DVB) stream is electronic program guides (EPG).One type DVB is hand-held digital video broadcast (DVB-H), and this is a kind of technology of recent exploitation, and it has increased available ability and service on small hand held devices (for example mobile phone).DVB-H is designed to the data passes of 10Mbps is arrived with battery powered terminal equipment.
Dvb transport stream transmits network via the third party audio frequency, video and the data passes of compressing is arrived the user.Motion Picture Experts Group (MPEG) is to be the technology of transport stream (TS) with video, audio frequency and the data of the coding in the single program and other program multiplexing.TS is packetized data flow, has the grouping of the regular length that comprises head.Carry each element of program, i.e. each in the Voice ﹠ Video with grouping with unique group character (PID).In order to make receiver device can locate the different elements of the specific program among the TS, provide the Program Specific Information (PSI) that embeds described TS.In addition,, promptly be attached to one group of table of the privately owned part sentence structure of MPEG, merge to described TS additional information on services (SI).Make like this receiver device correctly pack processing be contained in data among the described TS.
Yet the present invention also can be used for other conventional digital mobile broadcast systems, for example T-DAB, T/S-DMB, ISDB-T, ATSC, MediaFlow, and non-traditional systems, for example 3GPPMBMS (multimedia broadcast/multi broadcast service) and 3GPP2 BCMCS (broadcast).
Because image and other mass files account for main flow in ESG transmits, therefore need pass required network effectively and transmit the ESG fragment to terminal receiver.Yet, Previous System sent head before described ESG, efficient is very low like this, this is because if the container of carrying EGS was sent out before head, information can't be accessed till described head arrives so, and existence is not received the risk of described head thereby caused the described information in the container invalid.Current effort concentrates on a plurality of fragments is associated, yet, owing to lack the unique identification of described fragment, effective head or index structure, maybe needing to provide repeated parameter, described effort is mostly unsuccessful.
Summary of the invention
Various aspects of the present invention consider that the formation by container sends the ESG fragment to receiver efficiently.In this sense, container comprises at least one ESG fragment, but can hold a plurality of fragments.Perhaps, fragment can be carried in a plurality of containers.Described container is transmitted to receiver, for example by using asynchronous layer coding (ALC)/hierarchical coding to transmit (LCT) thus make single ALC/LCT transmission object corresponding to single container.The firm entire container that receives, described fragment just can be used by described receiver.Various aspects of the present invention have been used the simple and extendible head construction that separates with fragment, and are irrelevant with the type and the form of independent fragment.In a further embodiment, compression is used to entire container, comprises fragment and any head.In embodiment further, for example other of 3GPP metadata envelope are sealed and can be carried in the described container, repeat and need not unnecessary parameter, for example version, life span and sign.
In 3GPP (third generation partnership relation project) seals or can comprise specific channel, specific program and/or specific channel-group with other any type of metadata.The metadata of other types can comprise: grouped data, purchase data---as be used to finish as described in the Operator ID data and the technical data of affairs, for example address, agreement, based on grouping/sky, channel/minute, program/minute price data; Channel data---as be used for user's textual description, content supplier's brand message/logo, classification and level data---as type and parents' classification, channel SDP data---as use as described in the description of the required ability of service, for example Voice ﹠ Video form and bitrate information, start and end time, address, synchronized supplementary are supplied with address, attribute expansion; And program data, as quoting of user's textual description, start and end time, the interactive service relevant with program.Described metadata can be written into by operator or be finished automatically.

In the exemplary embodiment, head 310 can have a plurality of ESG fragment descriptor entries 330, ESG fragment 340 in the described descriptor entry sign container payload 320 makes receiver can determine the definite position and/or the length of each ESG fragment 340 of being comprised.For example, in one embodiment, the starting position of described specific ESG in container payload 120 specified by for example deviant 550, beginning and end point or similar are provided in the territory.In other embodiments, metadata 350 can be associated with single ESG fragment 340, near or be positioned among head 310, descriptor entry 330, ESG fragment 340 or its mix.In one exemplary embodiment, the 3GPP metadata envelope can replace or cancel demand relevant specific ESG fragment, that be arranged in the additional metadata of head 310 with the related of ESG fragment 340.
Fig. 4 shows and sends the method that a plurality of single objects transmit, and wherein said transmission is according at least one aspect of the present invention.As shown in Figure 4, transmission object of the present invention (TO) can be carried on, for example, and in FLUTE (file transfers of one-way transmission) session or the pure ALC session.In the example of Fig. 4, ESG root channel data, for example IP address, portal number and transmission Session ID (TSI) are stated in described IP/MAC notification table (INT table).The FLUTE session of ESG root channel comprises File Delivery Table and one or more transmission object (TO) of described session.Described transmission object is included in the mapping between the access parameter of dissimilar ESG and the different ESG sessions that wherein send the ESG data.ESG can be different, for example, adopts different language and/or have different coding and type.Described access parameter comprises IP address, portal number, TSI, start and end time, or the like.Described FLUTE session therefore statement how with the ESG data allocations to different sessions.The TO of the FLUTE session of carrying mapping (enum) data describes in the FDT of this FLUTE session.The ESG mapping (enum) data can transmit in one or more TO.Described mapping can be used XML diagram, simple ASCII text, structuring ASCII text---for example many parts MIME or MIME head, as the binary system of cited type or by other different modes known in the art, realize.In the present embodiment, transmit among one or more TO of ESG data in the ESG session, wherein said ESG session can be pure ALC session.Described ESG data can transmit in one or more ESG sessions.In certain embodiments of the invention, ESG data or its part can transmit in one or more FLUTE sessions except the ACL session or alternative ALC session.
Fig. 5 shows the block diagram according to the example frame of electronic service guide (ESG) fragment descriptor entries of at least one aspect of the present invention.Frame 500 shows the form of the protocol frame that is used for head 310.Frame 502A-D with descriptor entry is an illustrative examples, and it comprises the type of indicating clauses and subclauses 330 and the type field 505 of characteristic.Described type field can be expanded to allow to be used to increase new types of entries.By in territory 505, importing entry type, can offer the different information of receiver.We for frame example 502A-D pre-defined the certain metadata that is associated with fragment.For example in 502B, offset domain, beginning territory, end territory and basic URI territory are the metadata that is used for the associated clip of described payload.On the contrary, there is not to be any metadata of fragment association of its expression among the frame example 502C.
As mentioned above, payload can comprise to be sealed, perhaps type is the clauses and subclauses of predefine parameter that the ESG fragment that is arranged in described payload is provided, and wherein said sealing is associated self metadata and fragment (both be included in and seal in) or the indication metadata is arranged in head.And shown in frame 502C, single descriptor entry can be configured to describe a plurality of ESG fragments by its type, perhaps even the different editions of same ESG fragment.For example, frame 502A is marked as the Class1 clauses and subclauses, and comprises the information about described ESG fragment, for example position, form, version information, unique identifier.For this point is described, frame 502 can provide the additional information fields about ESG fragment 340, for example form 510, version 520, and unique identifier 530.In the exemplary embodiment, whether format field 510 regulation ESG fragments 500 are text, video and/or picture.Yet, those skilled in the art will recognize any information that format field 510 can stipulate to be included in the medium type in the ESG fragment 340 in fact.
Can comprise version field 520 to allow to upgrade the ESG that had before received.For example, newer ESG version can be detected automatically and be carried out, otherwise the expired ESG fragment of version field 520 defineds can not be performed or be performed according to receiver user's indication.But when the local service time spent, this also always of great use.For example, when portable terminal when a geographic area moves to another geographic area, some service may be still available, some may be no longer available, and some may become available.Therefore, some ESG object in new geographic area with the same effective in original geographic area.In an embodiment, terminal can be discerned described ESG object available in new geographic area, and can the no longer valid object of store/buffer.In another embodiment, terminal can receive and the storing ESG object from different frequency, IP platform and Virtual network operator, and afterwards these objects and ESG object from current network is incorporated among the unified ESG.
Alternatively, version field 520 can combine or alternative domain of validity 570 with domain of validity 570.Whether version field 520 can be indicated the ESG fragment that received is latest edition or is arranged to and determines whether to exist compatibility issue, and domain of validity 570 can further be distinguished the ESG fragment of useless or lower priority.As shown in Figure 5, one or more domain of validity 570 can be indicated the effective time period of associated fragment.Perhaps, validity can be based on the appearance of the hardware of receiver, user-defined setting and/or other ESG.For example, the appearance of position that node is loaded or basic URI no matter be in domain of validity 570 or other territories, can allow to verify received ESG fragment.In other embodiments, basic URI can allow receiver combination or alternative ESG fragment to use the information that is positioned at URI.
The sign that unique identifier territory 530 allows the ESG fragment, and no matter the information in the vessel head 310.For example, when a plurality of ESG are received, carry out, perhaps no longer be associated with head, it is overall when discernible perhaps needing, and described information is very useful.Except other employed territories, each in the above-mentioned information field 510,520,530 can comprise region filling 540 does not satisfy the byte rule of described clauses and subclauses with compensation part alternatively.For example, if the position of ESG fragment comprises the basic URI that enough bits are not provided for described clauses and subclauses, then can use ascii character (for example 0) to fill requisite space to satisfy the bit requirement.As disclosed, each ESG fragment can be encoded as the bit rate different with other ESG fragments.In another embodiment, different bit rates can be used to the different parameters among the single ESG, for example in different information fields 510,520,530.
