Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in more detail by the following examples.
Fig. 3 is the general structure schematic diagram of content association management system in the first embodiment of the invention.
With reference to Fig. 3, this content association management system comprises head end and terminal two large divisions.Wherein, the service provider of head end is mainly used in to home network terminal (HNED) and sends the relevance descriptor, terminal manages content according to these relevance descriptors, related the issuing of descriptor of content association can issue by broadcast channel or exchange channels, the agreement of using also can have multiple, for example DVB S/C/T or HTTP etc.
The function of each module is as described below among Fig. 3:
The service provider is used to provide program and the relevance descriptor relevant with described program, and described relevance descriptor comprises the trigger message of content, the association type of content and program.The terminal called module is stored in it in relevance information bank after being used to receive the program and program content association descriptor that the service provider issues, and communication module also is used for receiving in addition.The relevance information bank is mainly used in information such as memory contents association.
The content association administration module is used for the management to content association, and major function comprises: a) according to the trigger message in the relevance descriptor, trigger the content association administration module and begin to handle; B) query contents related information storehouse; C) because the corresponding different processing policy of different association type, so the content association administration module is according to the association type in the relevance descriptor, and the query processing policy library obtains processing policy; Described association type is the alternative of program in order to the relation of expression content association and program as content association, is the run-out of program, is the feature etc. of certain camera lens or some fragment.D) according to the processing policy that gets access to, call different processing module content association and handle accordingly; E) receiving processing module is handled end; F) receive the triggering message that startup content association that user interactive module passes over is handled; G) information in the content related information storehouse is put in order.
The processing policy storehouse be used for processing policy that storage server and terminal consult and and the processing policy that consults of user, described processing policy for example is: utilize the mode of picture-in-picture to show related content, substitute current content and show etc.In addition, the processing policy storehouse can also obtain the processing policy corresponding with content association for the inquiry of content association administration module.
User interactive module is mainly used in and user interactions, and the processing policy that obtains the user is stored in the processing policy storehouse, and the triggering message that obtains the user, is sent to the content association administration module.
The function of processing module 1～n is decided on the association type of related information, as: inquiry obtains the URI of content association, obtains this content association according to this URI, and content association replaces current content and shows; Inquiry obtains the URI of content association, obtains content association according to this URI, and mode and the main contents of content association with picture-in-picture shown simultaneously; Inquiry obtains the URI of content association, downloads content association to terminal according to this URI, or the like.
Figure 4 shows that the schematic flow sheet of the management of content association in the first embodiment of the invention.
As shown in Figure 4, this flow process comprises:
Step 202 is differentiated in the related descriptor table of current programme content control identifier whether for triggering identifier automatically, when it be automatically during the triggering identifier, forwards step 203 to, handles automatically; When being non-automatic triggering identifier, forward step 209 to, carry out and the similar non-automatic processing of prior art.
Step 203 is differentiated control identifier and whether is triggered this content association at the appointed time putting, if, then forward step 204 to, at the appointed time handle content association; Otherwise, forward step 207 to, handle content association immediately.
Step 204 in the content association table, is searched the automatic fixed time point that triggers in the option of fixed time point.
Step 206 according to processing policy, is called corresponding processing module, content association handled accordingly, as: the URI according to content association finds this content, utilizes the mode of picture-in-picture, and it is represented; URI according to content association finds this content, substitutes current content revealing; URI according to content association finds this content, and it is recorded; According to the URI of content association, download this content stores in this locality etc.After above-mentioned processing finishes, forward step 208 to, remove the relevance descriptor of handling.
Step 210 is differentiated the user and whether is had a mind to watch which content association, promptly watches the content association tabulation.If then forward step 211 to; Otherwise forward step 216 to.
Step 211 represents the content association tabulation of current program.
Step 212 is differentiated the user and whether is selected a certain content association, as: the chained address of clicking tabulation.If then forward step 213 to; Otherwise, forward step 214 to.
Step 213 according to the association type of related information, is searched the processing policy of content association.According to processing policy, carry out the relevant treatment of content association; As: the URI according to content association finds this content, utilizes the mode of picture-in-picture, and it is represented; URI according to content association finds this content, substitutes current content revealing; URI according to content association finds this content, and it is recorded; According to the URI of content association, download this content stores in this locality etc.Processing jumps to step 208 after finishing.
Step 214 is differentiated the link whether content association comprises the content association of non-automatic triggering.If then forward step 212 to; Otherwise forward step 215 to.
Step 216 is differentiated the link whether the content association tabulation comprises non-automatic triggering.If then jump to step 210; Otherwise, forward step 217 to.
The embodiment of the invention has realized the function to the triggering and the management of content association, and the process of this management all is to depend on the content association information that server end sends to terminal, and the form of this information is as described below.Content association information can be issued to terminal by broadcast channel, also can pass through the exchange channels incoming terminal.
Come from the relevance table of broadcast channel, its structure is as shown in table 7:
Table 7
| Syntax No.of?bits Format |
| related content section(){ table id 8 uimsbf section_syntax_indicator 1 bslbf reserved 1 bslbf reserved_future_use 2 bslbf section_length 12 uimsbf reserved 16 uimsbf reserved 2 bslbf version_number 5 uimsbf current_next_indicator 1 bslbf section_number 8 uimsbf last_section_number 8 uimsbf year_offset 16 uimsbf Link_count 8 uimsbf for(j＝0；j<link_count；j++){ |

Compare with table 2 of the prior art, table 7 has increased the related_content_trigger_code daughter element, be used for triggering terminal to handle associated content, and its concrete meaning, as shown in table 8.Though it should be noted that only to have provided here and receive that i.e. processing, at the appointed time processing, confession user select these several modes of reprocessing, the present invention is not limited to this several modes.
Table 8
| Value | The meaning of value |
| 0x00 | Keep |
| 0x01 | Receive promptly and handle |
| 0x02 | Time point in appointment is handled |
| 0x03 | Select reprocessing for the user |
| 0x04～0xFF | Keep |
When the related_content_trigger_code value was 0x02, table 7 had also further provided the deal_time daughter element, was used for informing that the time point that terminal is represented in this field handles accordingly to this content association.
Certainly, above-mentioned identifier related_content_trigger_code and deal_time can occur in the link_info () in the RCT table, and be as shown in table 9:
Table 9
| Syntax No.of?bits Format |
| link_info(){ related_content_trigger_code 8 uimsbf if(related_content_trigger_code＝＝0x02) { deal_time 16 uimsbf } link_type 8 uimsbf how_related 8 uimsbf if(link_type＝＝0x00||link_type＝＝0x02){ media_uri_length 8 for(k＝0；k<media_uri_length；k++){ media_uri_byte 8 uimsbf } } if(link_type＝＝0x01||link_type＝＝0x02){ dvb_binary_locator() } number items 8 uimsbf for(m＝0；m<number_items；m++){ ISO639-2_language_code 24 bslbf promotional_text_length 8 uimsbf for(n＝0；n<promotional_text_length；n++){ promotional_text_char 8 uimsbf } } reserved 4 uimsbf descriptor_loop_length 12 uimsbf for(p＝0；p<descriptor_loop_length；p++){ descriptor() 8 uimsbf } } |
Table 9 is compared with table 3 of the prior art, has increased related_content_trigger_code and deal_time daughter element.
For the trigger message of content association, also has the form in a kind of RCT of being present in table.The daughter element of above-mentioned trigger message is combined into a RCtrigger_descriptor () daughter element; This RCtrigger_descriptor () inside comprises related_content_trigger_code and deal_time, and is as follows:
RCtrigger_descriptor(){
related_content_trigger_code；
if(related_content_trigger_code＝＝0x02)
{
deal_time；
}
}
Then this table is positioned in the RCT table, as shown in table 10:
Table 10
| Syntax No.of?bits Format |
| related content section(){ table_id 8 uimsbf section_syntax_indicator 1 bslbf reserved 1 bslbf reserved_future_use 2 bslbf section_length 12 uimsbf reserved 16 uimsbf reserved 2 bslbf version_number 5 uimsbf current_next indicator 1 bslbf section_number 8 uimsbf last_section_number 8 uimsbf year_offset 16 uimsbf Link_count 8 uimsbf for(j＝0；j<link_count；j++){ reserved 4 uimsbf RCtrigger_descriptor(){ related_content_trigger_code 8 uimsbf if(related_content_trigger_code＝＝0x02) { deal_time 16 uimsbf } |
| } link_info_length 12 uimsbf link_info()uimsbf } CRC_32 32 rpchof} |
Perhaps be placed on the linkinfo () inside in the RCT table, as shown in table 11:
Table 11
| Syntax No.of?bits Format |
| link_info(){ RCtrigger_descriptor(){ related_content_trigger_code 8 uimsbf if(related_content_trigger_code＝＝0x02) { deal_time 16 uimsbf } } link_type 8 uimsbf how_related 8 uimsbf if(link_type＝＝0x00||link_type＝＝0x02){ media_uri_length 8 for(k＝0；k<media_uri_length；k++){ media_uri_byte 8 uimsbf } } if(link_type＝＝0x01||link_type＝＝0x02){ dvb_binary_locator() } number_items 8 uimsbf for(m＝0；m<number_items；m++){ ISO639-2_language_code 24 bslbf promotional_text_length 8 uimsbf for(n＝0；n<promotional_text_length；n++){ promotional_text_char 8 uimsbf } } |
| reserved 4 uimsbf descriptor_loop_length 12 uimsbf for(p＝0；p<descriptor_loop_length；p++){ descriptor() 8 uimsbf } } |
Table 10,11 is compared with table 7,9, is equivalent to replace independently daughter element related_content_trigger_code and deal_time with the daughter element RCtrigger_descriptor () of combination.
Different with above-mentioned broadcast channel, the information of relevance table that comes from the broadband channel in the embodiment of the invention is as shown in table 12:
Table 12
Compared with prior art, TriggerMethod and TriggerTime daughter element have been increased.Wherein, TriggerMethod is used for identifying the type of triggering, as: promptly trigger after receiving this information,, select triggering etc. for the user in the time point triggering of appointment.TriggerTime is expressed as the time point that triggers at the time point of appointment at TriggerMethod.These two identifiers all are in RelatedMaterialsType inside.
In addition, in the present embodiment, also each discrete daughter element of above-mentioned trigger message can be combined into a daughter element, promptly define a RCTiggerType daughter element, this daughter element contains TriggerMethod and two daughter elements of TriggerTime, and is specifically as shown in table 13:
Table 13
| RCTiggerType | Element 1 | 0...1 | The content association trigger message contains two daughter elements: (1) TriggerMethod (2) TriggerTime |
| TriggerMethod | Element 1.1 | 0...N | The mode that the connection content trigger of taking on a new look is handled comprises: receive promptly trigger, at the appointed time triggering, user trigger three kinds of situations. |
| TriggerTime | Element 1.1 | 0...N | When TriggerMethod handles at the appointed time triggering, essential.This time can also can be absolute time for relative time. |
General＜elementname=＂ RCTrigger ＂ type=＂ RCTriggerType then "/be placed in the RelatedMaterialType type as daughter element, as shown in table 14:
