Embodiment

Below we will be in conjunction with the accompanying drawings, several embodiments of the present invention are described in detail.

At first in conjunction with Fig. 2, respectively an embodiment of content type requesting method of the present invention and an embodiment of content type preparation method are described.As shown in Figure 2, comprising:

Step S201: be identified for identifying the content identification of content.

The content identification here can only identify a content, and for example, every film can corresponding sign, and described sign only identifies a film.In the form, content identification can be a single character string, also can be the precomposed character string that several character strings are formed, as: " T-345246800-1 ", " 02-01-2005 03-01-2005 05-01-2005 ".The precomposed character string is not limited to concrete form, as "＜MyID type=" ISWC "〉T-034.524.680-1＜/MyID〉" content identification expressed is that type is that ISWC and value are the stowed value of T-034.524.680-1 in fact.Specifically, content identification can be the digital digest that MD-5, SHA-1, SHA-256 scheduling algorithm calculate, also can be the combination of the value of httpURI (URL) and entity tag, the combination of the value of unique video identification sign indicating number UMID of the value of the SMPTE of Society of Motion Picture and Television Engineers correspondence and its definition.

Determine that content identification has a variety of modes.First kind of mode wherein can be: according to content itself or content metadata or content itself and content metadata, generate content identification, the metadata of content itself, content, content itself and content metadata can be preserved in advance, also can obtain from other network entities, in addition, when generating content identification according to content itself, content identification can be to generate according to the full detail of described content itself, partial information or corresponding synopsis; When generating described content identification according to content itself and content metadata, described content identification is to generate according to the full detail of described content itself and content metadata; When generating described content identification according to content itself and content metadata, described content identification is to generate according to the partial information of described content itself and content metadata; When generating described content identification according to content itself and content metadata, described content identification is to generate according to described content itself corresponding synopsis and content metadata.The second way can be: extract content identification from the message of the metadata of content or the carrying content that received.The third mode can be: obtain content identification from other network entities, for example, the metadata of content itself or content can be sent to certain entity, this entity is according to the metadata returned content sign of content itself or content, again for example, content identification can be provided in advance by other network entities.In addition, can determine content identification, for example, determine the definite content identification of rule according to the Versatile content sign of acquiescence according to multiple rule; Again for example, determine content identification according to the indication information (for example having pointed out that what is the content identification string with) of related content sign in the message of content metadata or the carrying content that received; Again for example, the content identification that provides according to the classifying content provider is established rules really and is then come to determine described content identification; Again for example, establish rules really according to the indication information of related content sign in the message of content metadata or the carrying content that received and content identification that the classifying content provider provides and then determine described content identification.More specifically, indication information can be indicated and be used which kind of rule to determine content identification, receive this indication after, generate or extract content identification according to this indication and get final product.The classifying content provider can preserve between the content type of a content and the content identification only one-to-one correspondence, and can have content identification and establish rules really then, if obtain that such content identification is established rules really then, then can establish rules really and then determine content identification according to this content identification.Certainly, above-mentioned dual mode can also be used in the lump, for example, have a plurality of definite rules in the indication information that obtains, if reentry the classifying content provider at this content pairing content identification establish rules really then, then can determine use which rule to determine which type of content identification accurately.

Step S202: use described content identification to classifying content provider request content classification.

The content identification here can be carried on and offer the classifying content provider in the content type request message, also can be independent of described content type request message and offer the classifying content provider.

That more than introduce is an embodiment of content type requesting method, in actual applications, uses content identification after classifying content provider request content classification, can also the received content classification provider content type definite according to content identification.For this reason, the present invention also provides an embodiment of content type preparation method.Still be example with Fig. 2, after the step S202, also comprise:

Step S203: the content type that received content classification provider determines according to described content identification.

The classifying content provider can return content type after determining content type according to content identification, so, use content identification after classifying content provider request content classification, can receive content type.Need to prove, some content identification can corresponding identical content type, so, if provide different content identifications to the classifying content provider, might obtain identical content type, but because content identification is used to identify content, therefore, even different content identifications is provided and obtains identical content type to the classifying content provider, these content types also are correct.

Below in conjunction with Fig. 3, content type of the present invention is determined that embodiment of method and content type provide an embodiment of method to describe.As shown in Figure 3, comprising:

Step S301: received content classification requesting party uses the request of content identification request content classification.Described content identification is used to identify content.

Step S302: determine content type according to described content identification.

Concrete, can preserve the corresponding relation between content identification and the content type in advance.Before preserving, need the corresponding relation between acquisition content identification and the content type.For example, can obtain content itself, perhaps content metadata, perhaps content itself and content metadata, generate content identification, owing to obtain content itself, perhaps content metadata, perhaps behind content itself and the content metadata, also must need classifying content, so just obtained the corresponding relation between content identification and the content type, wherein, content itself, perhaps content metadata, perhaps content itself and content metadata can be provided by other network entities, in addition, when generating content identification according to content itself, content identification can be the full detail according to described content itself, partial information or corresponding synopsis generate; When generating described content identification according to content itself and content metadata, described content identification is to generate according to the full detail of described content itself and content metadata; When generating described content identification according to content itself and content metadata, described content identification is to generate according to the partial information of described content itself and content metadata; When generating described content identification according to content itself and content metadata, described content identification is to generate according to described content itself corresponding synopsis and content metadata.Again for example, can obtain the metadata of content, from the metadata of content, extract content identification again, equally, owing to after obtaining content metadata, also must need classifying content has so just been obtained the corresponding relation between content identification and the content type, wherein, content metadata can be provided by other network entities.Again for example, can obtain content itself and content metadata, content be classified, and from the message of content metadata or the carrying content that received, extract content identification according to content itself or content itself and content metadata.Again for example, can also obtain the corresponding relation of content identification and content type from other network entities.Again for example, can also obtain to carry the message of content; According to the information of related content in the message of described carrying content or the content of carrying, content is classified, and from the message of described carrying content, extract content identification.After obtaining the corresponding relation of content identification and content type, can preserve the corresponding relation of content identification and content type.

If receive the request that the classifying content requesting party uses content identification request content classification, then can search the content type that mates with described content identification, the content type consistent with described content identification coupling is definite content type.

Need to prove, some content identification can corresponding identical content type, so, if receive the different content identification that the classifying content requesting party provides, the content type that finds may be identical, but because content identification is used to identify content, therefore, even receive different content identifications and find identical content type, these content types also are correct.

That more than introduce is the embodiment that content type is determined method, in actual applications, determine content type according to content identification after, content type can also be offered received content classification requesting party or other network entities.For this reason, the present invention also provides content type that an embodiment of method is provided.Still be example with Fig. 3, after the step S302, also comprise:

Step S303: described content type is offered classifying content requesting party and/or other network entities.

Concrete, if the classifying content requesting party indicates which network entity content type is not offered, then can give tacit consent to content type is returned to the classifying content requesting party, also any one network entity can be at random content type offered, certain or some network entities can also be according to actual needs content type offered.For example, do not indicate under the situation that content type is offered which network entity the classifying content requesting party, can be according to the request of certain or some network entities, content type is offered this or these network entity.If the classifying content requestor requests offers own and/or other network entities with content type, then can content type be offered classifying content requesting party and/or other network entities according to request.

Below in conjunction with Fig. 4, an embodiment of content type exchange method of the present invention is described.As shown in Figure 4, comprising:

Step S401: the classifying content requesting party is identified for identifying the content identification of content.

Determine that content identification has a variety of modes.First kind of mode wherein can be: according to content itself or content metadata or content itself and content metadata, generate content identification, content itself or content metadata or content itself and content metadata can be preserved in advance, also can obtain from other network entities, in addition, when generating content identification according to content itself, content identification can be to generate according to the full detail of described content itself, partial information or corresponding synopsis; When generating described content identification according to content itself and content metadata, described content identification is to generate according to the full detail of described content itself and content metadata; When generating described content identification according to content itself and content metadata, described content identification is to generate according to the partial information of described content itself and content metadata; When generating described content identification according to content itself and content metadata, described content identification is to generate according to described content itself corresponding synopsis and content metadata.The second way can be: extract content identification from the message of the metadata of content or the carrying content that received.The third mode can be: obtain content identification from other network entities, for example, the metadata of content itself or content can be sent to certain entity, this entity is according to the metadata returned content sign of content itself or content, again for example, content identification can be provided in advance by other network entities.In addition, can determine content identification, for example, determine the definite content identification of rule according to the Versatile content sign of acquiescence according to multiple rule; Again for example, determine content identification according to the indication information (for example having pointed out that what is the content identification string with) of related content sign in the message of content metadata or the carrying content that received; Again for example, the content identification that provides according to the classifying content provider is established rules really and is then come to determine described content identification; Again for example, establish rules really according to the indication information of related content sign in the message of content metadata or the carrying content that received and content identification that the classifying content provider provides and then determine described content identification.More specifically, indication information can be indicated and be used which kind of rule to determine content identification, receive this indication after, generate or extract content identification according to this indication and get final product.The classifying content provider can preserve between the content type of a content and the content identification only one-to-one correspondence, and can have content identification and establish rules really then, if obtain that such content identification is established rules really then, then can establish rules really and then determine content identification according to this content identification.Certainly, above-mentioned dual mode can also be used in the lump, for example, have a plurality of definite rules in the indication information that obtains, if reentry the classifying content provider at this content pairing content identification establish rules really then, then can determine use which rule to determine which type of content identification accurately.

Step S402: the classifying content requesting party uses described content identification to classifying content provider request content classification.

The classifying content requesting party can be carried on content identification and offer the classifying content provider in the content type request message, also content identification can be independent of described content type request message and offer the classifying content provider.

Step S403: the classifying content provider determines content type according to described content identification.

Concrete, the classifying content provider can preserve the corresponding relation between content identification and the content type in advance.Before preserving, the classifying content provider need obtain the corresponding relation between content identification and the content type.For example, the classifying content provider can obtain content itself, perhaps content metadata, perhaps content itself and content metadata, generate content identification, owing to obtain content itself, perhaps content metadata, perhaps behind content itself and the content metadata, also must need classifying content, so just obtained the corresponding relation between content identification and the content type, wherein, content itself, perhaps content metadata, perhaps content itself and content metadata can be provided by other network entities, in addition, when generating content identification according to content itself, content identification can be the full detail according to described content itself, partial information or corresponding synopsis generate; When generating described content identification according to content itself and content metadata, described content identification is to generate according to the full detail of described content itself and content metadata; When generating described content identification according to content itself and content metadata, described content identification is to generate according to the partial information of described content itself and content metadata; When generating described content identification according to content itself and content metadata, described content identification is to generate according to described content itself corresponding synopsis and content metadata.Again for example, the classifying content provider can obtain the metadata of content, from the metadata of content, extract content identification again, equally, owing to after obtaining content metadata, also must need classifying content has so just been obtained the corresponding relation between content identification and the content type, wherein, content metadata can be provided by other network entities.Again for example, the classifying content provider can obtain content itself and content metadata, according to content itself or content itself and content metadata content is classified, and from the message of content metadata or the carrying content that received, extract content identification.Again for example, the classifying content provider can also obtain the corresponding relation of content identification and content type from other network entities.Again for example, can also obtain to carry the message of content; According to the information of related content in the message of described carrying content or the content of carrying, content is classified, and from the message of described carrying content, extract content identification.After the classifying content provider obtains the corresponding relation of content identification and content type, can preserve the corresponding relation of content identification and content type.

If the classifying content provider receives the request that the classifying content requesting party uses content identification request content classification, then can search the content type that mates with described content identification, the content type consistent with described content identification coupling is definite content type.

Step S404: the classifying content provider offers classifying content requesting party and/or other network entities with described content type.

Concrete, if the classifying content requesting party indicates which network entity content type is not offered, then the classifying content provider can give tacit consent to content type is returned to the classifying content requesting party, also any one network entity can be at random content type offered, certain or some network entities can also be according to actual needs content type offered.For example, do not indicate under the situation that content type is offered which network entity the classifying content requesting party, the classifying content provider can be according to the request of certain or some network entities, and content type is offered this or these network entity.If the classifying content requestor requests offers own and/or other network entities with content type, then the classifying content provider can offer classifying content requesting party and/or other network entities with content type according to request.

In actual applications, filtering technique might relate to the mutual of content type, and this class technology is commonly referred to as filtration (CBCS, the Categorization Based Content Screening) technology based on classification.Below in conjunction with Fig. 5, Fig. 6 and Fig. 7, the filtering technique of using content type exchange method embodiment of the present invention is described.

As shown in Figure 5, can comprise two parts based on classified content filter frame (also can be called): information filtering unit (Content Screening Component) and classifying content unit (Content CategorizationComponent) based on classified content filtering server (CSS, Content Screening Server).The classifying content unit provides CBCS-1 interface, and information filtering unit and outside classifying content requesting party (Content Categorization Requestor) all can obtain the classification information of certain or some contents by this interface.CBCS (mainly referring to the information filtering unit) has 2 kinds of use patterns: invocation pattern and proxy mode.In invocation pattern, content filtering request (Content ScreeningRequestor) sends to the information filtering unit by the PEM-1 interface with content, the information filtering unit to information filtering after, give content filtering request by PEM-1 interface return results, content filtering request will be filtered pass through interior according to the result who returns and perhaps be refused to point out to wait to send to the user.In proxy mode, the information filtering unit by proxy interface and to the interface of other resource to carrying out information filtering alternately between target resource requesting party (theTarget Resource Requestor) and the target resource (Target Resource), whether decision distributes its mutual content.

Need to prove, above-mentioned logically can be independent of other network entities based on the classified content filtering server, but may be integrated in physically on the existing equipment, also may be an independent equipment, two unit of its inside may centralized configuration, also possibility separate configuration.

Fig. 6 is based on the schematic diagram of first Application Example of the filtering technique of classification.As shown in Figure 6, comprise the steps:

Step S601: content providers (CP, Content Provider) sends to taxon (CC, Categorization Component) with content, and request is its classification.

Step S602: taxon is classified to content, uses the MD-5 algorithm to generate digital digest, and preserves the corresponding relation of digital digest and content type.

Step S603: content providers is to filter element (SC, Screening Component) request filtering content.

Step S604: filter element uses the MD-5 algorithm to generate digital digest according to the indication in the request.

Step S605: filter element carries the digital digest that generates to taxon request content classification in above-mentioned steps in the request.

Step S606: taxon is according to the digital digest received, and the digital digest that coupling has been preserved and the corresponding relation of classification are found out the content type of digital digest correspondence.

Step S607: taxon returns to filter element with content type.

Fig. 7 is based on the schematic diagram of second Application Example of the filtering technique of classification.In this Application Example, the version that the film " Great Dynasty " of supposing X film company is prepared issue on the net is GD_3W.As shown in Figure 7, comprise the steps:

The server of step S701:X film company (ServerX) sends to separated film administrative center (MCMC, Movie Categorization Management Center) with GD_3W, and request is its classification.

Step S702: separated film administrative center classifies, and extracted from the metadata of GD_3W that the third party provides with the unique corresponding sequence number GreatDynsty-DICAPRIO-WINSLET-1997 of content and third-party identifier MPAA sign as content, and preserve the corresponding relation of this sign and classification.

Step S703: separated film administrative center notice ServerX classifies successfully.

The server of step S704:X film company is added on the information of separated film administrative center in the metadata of GD_3W as the classification provider, and it is issued on the net, watches for the user.

Step S705: the terminal use has asked GD_3W, and GD_3W has been sent to the terminal use and has subscribed to the content filter server (CSS) of filtering services in being sent to terminal use's process.

Step S706: content filter server parses metadata, and this has data to find " classification provider ", so according to the sign create-rule of separated film administrative center, extract third party's identifier and content sequence number as sign.

Step S707: content filter server sends to sign separated film administrative center and asks classification.

Step S708: separated film administrative center mates according to the sign of receiving, finds corresponding class.

Step S709: separated film administrative center returns to content filter server with classification.

Step S710: content filter server filters according to the classification of receiving.

In addition, mentioned in the above, the classifying content requesting party can obtain content identification from other network entities, below in conjunction with Fig. 8, introduces the Application Example of the content type exchange method under a kind of this mode.

As shown in Figure 8, comprise step:

Step S801: server A (ServerA) is according to the default identification create-rule at webpage, obtain the sign of webpage to the server B of preserving web page resources (ServerB), its sign can be URI and entity tag, also can be URI and the last-update time, can also be URI, entity tag and the last-update time, wherein, the URI here is meant http URI, that is URL.

Step S802: server A is asked classification with sign to content classified service device (CCS, ContentCategorization Server).

Step S803: classifying content server matching identification and classification, wherein, the sign in the classifying content server and the corresponding relation of classification are provided by other network entities.

Step S804: the classifying content server returns to server A with classification.

Because method embodiment of the present invention can be realized by the device of various ways, so the present invention also provides a kind of embodiment of content type request unit, embodiment, the embodiment that content type is determined device, the embodiment of content type generator and the embodiment of content type interactive device that content type obtains device.

The embodiment of above-mentioned content type request unit can comprise: the content identification determining unit is used to be identified for identifying the content identification of content; Transmitting element is used to use the definite content identification of content identification determining unit to classifying content provider request content classification.

The content identification determining unit has a variety of modes can determine content identification.First kind of mode wherein can be: according to content itself or content metadata or content itself and content metadata, generate content identification, content itself or content metadata or content itself and content metadata can be preserved in advance, also can obtain from other network entities, in addition, when generating content identification according to content itself, content identification can be to generate according to the full detail of described content itself, partial information or corresponding synopsis; When generating described content identification according to content itself and content metadata, described content identification is to generate according to the full detail of described content itself and content metadata; When generating described content identification according to content itself and content metadata, described content identification is to generate according to the partial information of described content itself and content metadata; When generating described content identification according to content itself and content metadata, described content identification is to generate according to described content itself corresponding synopsis and content metadata.The second way can be: extract content identification from the message of the metadata of content or the carrying content that received.The third mode can be: obtain content identification from other network entities, for example, the metadata of content itself or content can be sent to certain entity, this entity is according to the metadata returned content sign of content itself or content, again for example, content identification can be provided in advance by other network entities.In addition, can determine content identification, for example, determine the definite content identification of rule according to the Versatile content sign of acquiescence according to multiple rule; Again for example, determine content identification according to the indication information (for example having pointed out that what is the content identification string with) of related content sign in the message of content metadata or the carrying content that received; Again for example, the content identification that provides according to the classifying content provider is established rules really and is then come to determine described content identification; Again for example, establish rules really according to the indication information of related content sign in the message of content metadata or the carrying content that received and content identification that the classifying content provider provides and then determine described content identification.More specifically, indication information can be indicated and be used which kind of rule to determine content identification, receive this indication after, generate or extract content identification according to this indication and get final product.The classifying content provider can preserve between the content type of a content and the content identification only one-to-one correspondence, and can have content identification and establish rules really then, if obtain that such content identification is established rules really then, then can establish rules really and then determine content identification according to this content identification.Certainly, above-mentioned dual mode can also be used in the lump, for example, have a plurality of definite rules in the indication information that obtains, if reentry the classifying content provider at this content pairing content identification establish rules really then, then can determine use which rule to determine which type of content identification accurately.

In addition, transmitting element can be carried on content identification and offer the classifying content provider in the content type request message, also content identification can be independent of described content type request message and offer the classifying content provider.

Above-mentioned content type obtains the embodiment of device, and can comprise: the content identification determining unit is used to be identified for identifying the content identification of content; Transmitting element is used to use the definite content identification of content identification determining unit to classifying content provider request content classification; Receiving element, the content type that the content identification that being used for received content classification provider provides according to described transmitting element is determined.

Explanation about content identification determining unit among the explanation of content identification determining unit and transmitting element and the foregoing classification request unit embodiment and transmitting element is identical, gives unnecessary details no longer one by one here.

After the classifying content provider determines content type according to content identification, content type can be returned to the foregoing classification and obtain device embodiment, so transmitting element uses content identification after classifying content provider request content classification, receiving element can receive content type.Need to prove, some content identification can corresponding identical content type, so, if transmitting element provides different content identifications to the classifying content provider, receiving element might obtain identical content type, but because content identification is used to identify content, therefore, even transmitting element provides different content identifications to the classifying content provider, and receiving element obtains identical content type, and these content types also are correct.

Above-mentioned content type is determined device embodiment, can comprise: receiving element is used for the request that received content classification requesting party uses content identification request content classification; The content type determining unit is used for determining content type according to the content identification that described receiving element obtains.

In addition, above-mentioned content type determines that device embodiment before determining content type, can preserve the corresponding relation between content identification and the content type in advance.Before preserving, need the corresponding relation between acquisition content identification and the content type.For example, can obtain content itself, perhaps content metadata, perhaps content itself and content metadata, generate content identification, owing to obtain content itself, perhaps content metadata, perhaps behind content itself and the content metadata, also must need classifying content, so just obtained the corresponding relation between content identification and the content type, wherein, content itself, perhaps content metadata, perhaps content itself and content metadata can be provided by other network entities, in addition, when generating content identification according to content itself, content identification can be the full detail according to described content itself, partial information or corresponding synopsis generate; When generating described content identification according to content itself and content metadata, described content identification is to generate according to the full detail of described content itself and content metadata; When generating described content identification according to content itself and content metadata, described content identification is to generate according to the partial information of described content itself and content metadata; When generating described content identification according to content itself and content metadata, described content identification is to generate according to described content itself corresponding synopsis and content metadata.Again for example, can obtain the metadata of content, from the metadata of content, extract content identification again, equally, owing to after obtaining content metadata, also must need classifying content has so just been obtained the corresponding relation between content identification and the content type, wherein, content metadata can be provided by other network entities.Again for example, can obtain content itself and content metadata, content be classified, and from the message of content metadata or the carrying content that received, extract content identification according to content itself or content itself and content metadata.Again for example, can also obtain the corresponding relation of content identification and content type from other network entities.Again for example, can also obtain to carry the message of content; According to the information of related content in the message of described carrying content or the content of carrying, content is classified, and from the message of described carrying content, extract content identification.After obtaining the corresponding relation of content identification and content type, can preserve the corresponding relation of content identification and content type.

If receiving element receives the request that the classifying content requesting party uses content identification request content classification, then the content type determining unit can be searched the content type that mates with described content identification, and the content type consistent with described content identification coupling is definite content type.

Need to prove, some content identification can corresponding identical content type, so, if receiving element receives the different content identification that the classifying content requesting party provides, the content type that the content type determining unit finds may be identical, but because content identification is used to identify content, therefore, even receiving element receives different content identifications and the content type determining unit finds identical content type, these content types also are correct.

Above-mentioned content type generator embodiment can comprise: receiving element is used for the request that received content classification requesting party uses content identification request content classification; The content type determining unit is used for determining content type according to the content identification that described receiving element obtains; Transmitting element is used for the content type that described content type determining unit is determined is offered classifying content requesting party and/or other network entities.

The explanation of determining receiving element among the device embodiment and content type determining unit about the explanation of receiving element and content type determining unit and foregoing classification is identical, gives unnecessary details no longer one by one here.

If the classifying content requesting party indicates which network entity content type is not offered, then transmitting element can be given tacit consent to content type is returned to the classifying content requesting party, also any one network entity can be at random content type offered, certain or some network entities can also be according to actual needs content type offered.For example, do not indicate under the situation that content type is offered which network entity the classifying content requesting party, transmitting element can be according to the request of certain or some network entities, and content type is offered this or these network entity.If the classifying content requestor requests offers own and/or other network entities with content type, then transmitting element can offer classifying content requesting party and/or other network entities with content type according to request.

The embodiment of above-mentioned content type interactive device, can comprise classifying content requesting party and classifying content provider, wherein, described classifying content requesting party is used to be identified for identifying the content identification of content, and uses content identification to described classifying content provider request content classification; Described classifying content provider is used for determining content type according to described content identification, and provides described content type to described classifying content requesting party and/or other network entities.

The classifying content requesting party determines that content identification has a variety of modes.First kind of mode wherein can be: according to content itself or content metadata or content itself and content metadata, generate content identification, content itself or content metadata or content itself and content metadata can be preserved in advance, also can obtain from other network entities, in addition, when generating content identification according to content itself, content identification can be to generate according to the full detail of described content itself, partial information or corresponding synopsis; When generating described content identification according to content itself and content metadata, described content identification is to generate according to the full detail of described content itself and content metadata; When generating described content identification according to content itself and content metadata, described content identification is to generate according to the partial information of described content itself and content metadata; When generating described content identification according to content itself and content metadata, described content identification is to generate according to described content itself corresponding synopsis and content metadata.The second way can be: extract content identification from the message of the metadata of content or the carrying content that received.The third mode can be: obtain content identification from other network entities, for example, the metadata of content itself or content can be sent to certain entity, this entity is according to the metadata returned content sign of content itself or content, again for example, content identification can be provided in advance by other network entities.In addition, can determine content identification, for example, determine the definite content identification of rule according to the Versatile content sign of acquiescence according to multiple rule; Again for example, determine content identification according to the indication information (for example having pointed out that what is the content identification string with) of related content sign in the message of content metadata or the carrying content that received; Again for example, the content identification that provides according to the classifying content provider is established rules really and is then come to determine described content identification; Again for example, establish rules really according to the indication information of related content sign in the message of content metadata or the carrying content that received and content identification that the classifying content provider provides and then determine described content identification.More specifically, indication information can be indicated and be used which kind of rule to determine content identification, receive this indication after, generate or extract content identification according to this indication and get final product.The classifying content provider can preserve between the content type of a content and the content identification only one-to-one correspondence, and can have content identification and establish rules really then, if obtain that such content identification is established rules really then, then can establish rules really and then determine content identification according to this content identification.Certainly, above-mentioned dual mode can also be used in the lump, for example, have a plurality of definite rules in the indication information that obtains, if reentry the classifying content provider at this content pairing content identification establish rules really then, then can determine use which rule to determine which type of content identification accurately.

In addition, the classifying content requesting party can be carried on content identification and offer the classifying content provider in the content type request message, also content identification can be independent of described content type request message and offer the classifying content provider.

In addition, the classifying content provider determines before the content type, can preserve the corresponding relation between content identification and the content type in advance.Before preserving, the classifying content provider need obtain the corresponding relation between content identification and the content type.For example, the classifying content provider can obtain the content type of content own, generate content identification, owing to obtain content itself, perhaps content metadata, perhaps behind content itself and the content metadata, also must need classifying content, so just obtained the corresponding relation between content identification and the content type, wherein, content itself, perhaps content metadata, perhaps content itself and content metadata can be provided by other network entities, in addition, when generating content identification according to content itself, content identification can be the full detail according to described content itself, partial information or corresponding synopsis generate; When generating described content identification according to content itself and content metadata, described content identification is to generate according to the full detail of described content itself and content metadata; When generating described content identification according to content itself and content metadata, described content identification is to generate according to the partial information of described content itself and content metadata; When generating described content identification according to content itself and content metadata, described content identification is to generate according to described content itself corresponding synopsis and content metadata.Again for example, the classifying content provider can obtain the metadata of content, from the metadata of content, extract content identification again, equally, owing to after obtaining content metadata, also must need classifying content has so just been obtained the corresponding relation between content identification and the content type, wherein, content metadata can be provided by other network entities.Again for example, the classifying content provider can obtain content itself and content metadata, according to content itself or content itself and content metadata content is classified, and from the message of content metadata or the carrying content that received, extract content identification.Again for example, the classifying content provider can also obtain the corresponding relation of content identification and content type from other network entities.Again for example, can also obtain to carry the message of content; According to the information of related content in the message of described carrying content or the content of carrying, content is classified, and from the message of described carrying content, extract content identification.After the classifying content provider obtains the corresponding relation of content identification and content type, can preserve the corresponding relation of content identification and content type.

Need to prove, some content identification can corresponding identical content type, so, if the classifying content provider receives the different content identification that the classifying content requesting party provides, the content type that finds may be identical, but because content identification is used to identify content, therefore, even the classifying content provider receives different content identifications and finds identical content type, these content types also are correct.

In addition, if the classifying content requesting party indicates which network entity content type is not offered, then the classifying content provider can give tacit consent to content type is returned to the classifying content requesting party, also any one network entity can be at random content type offered, certain or some network entities can also be according to actual needs content type offered.For example, do not indicate under the situation that content type is offered which network entity the classifying content requesting party, the classifying content provider can be according to the request of certain or some network entities, and content type is offered this or these network entity.If the classifying content requestor requests offers own and/or other network entities with content type, then the classifying content provider can offer classifying content requesting party and/or other network entities with content type according to request.

Need to prove that in said apparatus embodiment, the classifying content provider has the filter that content is carried out filtering function.

In the prior art, the classifying content requesting party uses the request content classification of content own sometimes.And in an embodiment of the present invention, the classifying content requesting party is used to identify the content identification request content classification of content.Because the size of content identification can be less than the size of content itself, so embodiments of the invention can be saved the interface data bandwidth.

The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
