The memory 40 storages information relevant with the allomeric function of DVB-H receiving terminal, and storage is supplied for example relevant information of ESG data with broadcast service.For memory was used in storage in 40 minutes will be in the specific region of the ESG data of using by DVB-H transmission server time designated date.That is to say, only when arriving time scheduled date, just will be stored in the interior ESG Data Update of dedicated memory space to wherein storing in the current ESG memory of data zone.
Next, be described in the operation that receives the ESG data of having used the session division rule in the DVB-H receiving terminal with said structure.At this moment, the DVB-H receiving terminal obtains the ESG data based on the partition declaration that defines as shown in Figure 4.
Fig. 4 shows the grammer according to the partition declaration in the ESG initialization container of exemplary embodiment of the present invention.With reference to Fig. 4, constitute overlapping field 100 with 1.If conversation applications is term of validity rule, then overlapping field 100 is set to one (1).Otherwise, overlapping field 100 is set to zero (0).Shown in reference number 110, field_length[k] constitute and represent the length value of the field of the concrete rule of indication by 4 bytes.If " field_length[k] " value 110 is variate-values, for example is value " 0x00 ", then " length[i] [k] " value of field 120 is set to the length value of actual field.
On the other hand, when any one in a plurality of sessions of current transmission all do not have application rule, " field_length[k] " value 110 and " length[i] [k] " value unconditionally can be set to zeroly, judge thereby can whether be applied to each session at dependency rule.If " length[i] [k] " value is zero, then the DVB-H receiving terminal need not check extra condition just easily decision rule be not applied to associated session.If " length[i] [k] " value is zero, the length that then means the field of represent ad hoc rules is zero.In this case, the DVB-H receiving terminal can judge that ad hoc rules is not applied to this session when receiving session.
But, if " field_length[k] " value 110 is fixed values, for example, be the value that is different from " 0x00 ", then judge for the ad hoc rules of whether having used each session according to the value of overlapping field 100.According to the value that sets for overlapping field 100, judge whether to have enabled by term of validity field shown in the reference number 130, that have the temporal information relevant with the term of validity of ESG data.Specifically, term of validity field 130 existing " start_field_value " that wherein are provided with the time started have " end_field_value " that wherein is provided with the plan concluding time again, and " end_field_value " perhaps only arranged.The DVB-H receiving terminal compares " start_field_value " and " end_field_value " and judges whether to have used dependency rule then.
For example, if overlapping field 100 is set to 1, then " start_field_value " of the DVB-H receiving terminal current sessions that will be estimated automatically by " end_field_value " of previous session compares with " end_field_value " of current sessions, and judges whether these values are mutually the same.If overlapping field 100 is set to zero, then whether identical judging whether used ad hoc rules to associated session to " start_field_value " of DVB-H receiving terminal by judging current sessions with " end_field_value ".
In another embodiment of the invention, when with the length value of the field of expression ad hoc rules corresponding " field_length[k] " when value 110 is fixed value, with " start_field_value " and " end_field_value " be assigned as irrelevant with previous session, also promptly with the irrelevant predetermined bit string of the value of overlapping field 100, and make the DVB-H receiving terminal can judge whether to have used the rule of associated session.For example, in current DVB-CBMS phase-I ESG spec, can there be the term of validity (hourage) rule and service URI rule.If in specific IP stream, only used term of validity rule, then the gamut in the associated session used service URI.If only used service URI rule, then to associated session in the relevant full-time service with ESG use the term of validity.At this moment, the minimum value of " start_field_value " and the maximum of " end_field_value " among the service URI can be assigned as special-purpose bit string.Minimum value can be set to " 0xFF " or be set to string format " a ".Maximum can be set to " 0xFF " or string format " z ".Be assigned as minimum value and peaked value and be not actual minimum and maximum in the associated session, but the minimum value on the expression mathematical meaning and represent infinitely-great peaked special-purpose bit string in the data type of dependency rule.That is to say that maximum is identical with the maximum of one month ESG, even when having the information on services in a week among the relevant ESG, also be like this.In this exemplary embodiment, should between rule or data class, predefine represent different minimum values and peaked bit string.
Replacedly, " start_field_value " and " end_field_value " can be assigned as and the irrelevant special-purpose bit string of the variable or fixed-length value of the field of representing ad hoc rules.For this reason, should between terminal and network, be scheduled to special-purpose bit string as described above.For example, in current DVB-CBMS phase-IESG spec, can there be term of validity rule and service URI rule.If in specific IP stream, only used term of validity rule, then the gamut in the associated session used service URI.If only used service URI rule, then the term of validity is used in the full-time service relevant with the ESG in the associated session.At this moment, the minimum value of " start_field_value " among the service URI and the maximum of " end_field_value " are assigned as special-purpose bit string.Under the situation of " 0x00 " or string, can minimum value be set to " a " or similar value.Under the situation of " 0x00 " or string, can maximum be set to " z " or similar value.Be assigned as minimum value and peaked value and be not actual minimum and maximum in the associated session, but the minimum value on the expression mathematical meaning and represent infinitely-great peaked special-purpose bit string in the data type of dependency rule.That is to say that maximum is identical with the maximum of one month ESG, even when having the information on services in a week among the relevant ESG, also be like this.In this exemplary embodiment, should between rule or data type, predefine represent different minimum values and peaked bit string.
When for example, when the term of validity, service URI and the such rule of the compound rule of time on date are applied to each session, the DVB-H receiving terminal has judged whether to each each and every one conversation applications ad hoc rules, so that handle the ESG data, this is because may be not to specific conversation applications ad hoc rules.
When the session of ad hoc rules had been used in reception, the DVB-H receiving terminal was by reading " field_identifier[k] " value of field 105 detects the type of the rule of practical application.Based on be provided with giving " field_identifier[k] " type of the rule of the value of field 105 can be expressed as shown in form 1.

Form 1 is illustrated in the rule type that defines in the DVB-H ESG standard.Use desired division rule by the value of change to be provided with giving " field_identifier[k] " field 105.
Next, the operation that is used for receiving at the DVB-H receiving terminal based on partition declaration as shown in Figure 4 the ESG data of having used the session division rule will be described.
Describe according to the first exemplary embodiment DVB-H receiving terminal of the present invention with reference to Fig. 5 and to obtain the processing procedure of ESG data, the flow chart of the operation of DVB-H receiving terminal when Fig. 5 shows and uses term of validity rule according to first exemplary embodiment of the present invention by the term of validity that detects appointment in the session of carrying the ESG data therein.
With reference to Fig. 5, in step 200, when the user carried out broadcast service, the DVB-H receiving terminal received the ESG boot sessions.When receiving the ESG boot sessions, in step 205, this ESG boot sessions analyzed by the DVB-H receiving terminal and whether the decision operation pattern is the multithread pattern.If operator scheme is not the multithread pattern, then in step 210, terminal determines that this operator scheme is a single-stream mode, retrieves relevant session and receives all ESG data.If this operator scheme is the multithread pattern, then in step 215, the terminal analysis division rule.Specifically, when receiving the ESG boot sessions, the ESG transfer of data begins.This boot sessions comprises ESG provider descriptor and ESG visit descriptor.ESG visit descriptor has the statement wheel changes the information that transmits session.When receiving the initialization container, in the initialization container, comprise partition declaration information by detection statement wheel commentaries on classics transmission session.In exemplary embodiment of the present invention, terminal can use partition declaration information to detect rule to the conversation applications that transmits actual ESG data.
In step 215, the DVB-H receiving terminal judges whether to have used term of validity rule by analyzing division rule.At this moment, if in Fig. 4 " field_identifier[k] " field 105, be provided with form 1 in corresponding " 0x00 " value of first value, what then the DVB-H receiving terminal was judged application is term of validity rule.In Fig. 5, what illustrate is data processing operation when using term of validity rule, supposes to have used term of validity rule.That is to say that the DVB-H receiving terminal detects by the division rule analyzing and processing and detects the state of using term of validity rule.
As mentioned above, the DVB-H receiving terminal can obtain the information relevant with each session by analyzing partition declaration.Like this, in step 220, the DVB-H receiving terminal is by judging whether to also have any session to be received to retrieve each session.When no longer including session and will receive, the DVB-H receiving terminal advances to step 225, so that the ESG data that session was obtained that receive so far make up and the indicated channel tabulation based on passing through to.
But, when having judged that in step 220 when also having more session to receive, the DVB-H receiving terminal advances to step 230, judges in the partition declaration from Fig. 4 whether the value of overlapping field 100 is set to 1.When the value of judging overlapping field 100 was not set to 1, in step 235, the DVB-H receiving terminal ascending order of concluding time according to schedule received data.That is to say that the DVB-H receiving terminal only reads the end_field_value of the plan concluding time of expression term of validity field, and obtain the ESG data by ascending order access session according to end_field_value.
If the value of overlapping field 100 is set to 1, then the DVB-H receiving terminal receives the ESG data according to the ascending order of time started in step 240.That is to say that the DVB-H receiving terminal reads the start_field_value of the time started of expression term of validity field 130, and obtain the ESG data by ascending order access session according to start_field_value.
At this moment, in step 245, the DVB-H receiving terminal judges that the plan concluding time is whether within a week.Carry out this judgement and be in order to receive only required optimum data of broadcast service and data that demonstration received earlier.When the plan concluding time was all more than one, in step 250, the DVB-H receiving terminal received remaining ESG data in background process after having shown channel list based on the ESG data of being obtained.For the time started that makes broadcast service minimizes, also be, stand-by period before user's service of going on the air is minimized, and terminal is carried out background process during corresponding session data receiving with predetermined amount of time (for example a, week) the plan concluding time afterwards.In exemplary embodiment of the present invention, provide the time period of the required optimum data of broadcast service to be set to a week.Certainly, the reference time can be according to the difference of DVB-H receiving terminal and difference.
When the decision plan concluding time in step 245 is within the week time, and in step 255, the DVB-H receiving terminal turns back to step 220 then with the form storage data of union (union set), judges whether to also have any session to receive.According to the operation of judged result with previously described identical.Next, with the processing procedure of describing in detail with the form storage data of union.
When the information of the data of having stored had the ID identical with the ID of the ESG fragment data that receives in the new session, the DVB-H receiving terminal can reconfigure the union of the data of two fragments according to following order.
At first, during the ID of the fragment that equals to have stored as the ID of the new segment that will store,, then do not store this new segment if by the version of new segment and the version that compares to determine new segment between the version of stored fragments is lower.
Secondly, when the version of the new segment that will store is higher, deletion old film section and replace it with new segment.
Once more, when the version of two fragments is identical, between the element units of fragment and template(-let), compare.When having new element and attribute data, the data that storage is associated.That is the union of two fragments of configuration.
When the version of two fragments is identical, judge whether employed rule has the profile form in each session, fragment is cut apart and is transmitted in this form.If fragment transmits with the profile form, then dispose union.Otherwise, ignore new transmitted same clip.
As mentioned above, according to first exemplary embodiment of the present invention, the DVB-H receiving terminal can only obtain the required optimum data of broadcast service earlier and can significantly improve reception programme by obtaining based on the ESG data of term of validity rule.
Next, describe according to second exemplary embodiment of the present invention by reading the processing procedure that service URI specified in each session of wherein carrying the ESG data obtains the ESG data with serving one by one with reference to Fig. 6, Fig. 6 is the flow chart that illustrates according to second exemplary embodiment of the present invention operation of DVB-H receiving terminal when the application service URI rule.
Since the step 300 among Fig. 6 and 315 operation basically with Fig. 5 in step 200 and 215 identical, therefore here no longer repeat to describe in detail.
The step 315 of analyzing division rule is different with step 215, and this is because the DVB-H receiving terminal judges whether to have used service URI rule.Therefore, when " field the identifier[k] " field 105 among Fig. 4 be set to form 1 in corresponding " 0x01 " value of second value the time, service URI rule has been used in the judgement of DVB-H receiving terminal.Data processing operation when having used service URI rule among Fig. 6, what suppose to use is to serve the URI rule.
If used service URI rule, then in step 320, the DVB-H receiving terminal judges whether to also have any session to receive.When judging that session will receive in addition, the DVB-H receiving terminal advances to step 325, to receive and to store the ESG data of serving the URI session one by one.Then, the DVB-H receiving terminal advances to step 330, with the form storage data of union, and turns back to step 320, to judge whether also having any session to receive.Will receive if no longer include session, then the DVB-H receiving terminal advances to step 335, to tabulate based on ESG data construct that up to the present obtains and indicated channel.
When receiving according to the present invention described above second exemplary embodiment when having used the session of service URI rule, the DVB-H receiving terminal receives all sessions, because the data that need all URI are to provide broadcast service.
The processing procedure of in this time on date the ESG data of being obtained from session being upgraded by reading in the time on date set in the session of wherein carrying the ESG data according to the 3rd exemplary embodiment DVB-H receiving terminal of the present invention with reference to the flow chart description that provides among Fig. 7.
Step 400 among Fig. 7 to 415 basically with Fig. 5 in step 200 to 215 identical.In the step 415 of Fig. 7, the DVB-H receiving terminal is analyzed division rule and is judged whether to have used the date time rule.In DVB-H ESG standard, do not define the date time rule.In exemplary embodiment of the present invention, the time on date will be added in the available from now on rule.Like this, can be set to the time on date and the corresponding value " 0x02-0xEF " of the 3rd value of form 1.
Used the date during time rule when judging as the result who analyzes division rule, in step 420, the DVB-H receiving terminal has judged whether that session will receive.In step 430, the DVB-H receiving terminal judges whether associated session has been used the date time value.When having judged that not the DVB-H receiving terminal advances to step 435, to receive and to store the ESG data by direct visit current sessions to conversation applications date during time value.When to conversation applications date during time value, the DVB-H receiving terminal advances to step 440, to judge that this time on date is whether after the current time.Not after the current time, then current sessions is considered as unwanted session if judge the time on date.The DVB-H receiving terminal turns back to step 420, will receive to have judged whether next session.Date time rule indication should accurately be applied to the DVB-H receiving terminal in the data that will have been used the session of dependency rule by the specified time of time on date.If the fixed time not after the current time, then means passed through the time that associated session is applied to the DVB-H receiving terminal, so that in current sessions, do not received the ESG data.
But, when judging that in step 440 time on date is after the current time time, the DVB-H receiving terminal advances to step 445, with the ESG storage in the specific memory space.Storing ESG data is in order to upgrade processing by the time of time on date appointment, and need not immediately the DSG data to be applied to application program, even also be like this when the DVB-H receiving terminal has received the ESG data.When no longer including session will receive in above-mentioned processing, the DVB-H receiving terminal advances to step 425, based on ESG data construct that is up to the present obtained and indicated channel tabulation.
In the 3rd exemplary embodiment of the present invention, advantage is, the service provider specifies the ESG data of expectation and the time of expectation, and makes all DVB-H receiving terminals can receive the ESG data simultaneously when receiving the ESG data of having used the date time rule.
The example that a division rule is applied to a session has been described.Replacedly, can be with complex form with at least one rule application in each session.When using compound rule, the operational processes of DVB-H receiving terminal is as follows.
The compound rule that can define in current standard is the combination of the term of validity and service URI.According to this combination, the operation of DVB-H receiving terminal is identical with the operation of describing with reference to Fig. 5.In other words, owing to should receive and all service URI corresponding all data, so this operation can carry out according to the flow process of only considering term of validity rule, and do not need the extra service URI that considers.
On the other hand, it is also conceivable that the two the situation of term of validity rule and date time rule of using.In this case, the DVB-H receiving terminal has at first judged whether to use the session of date time rule.Then, the DVB-H receiving terminal will have been used the ESG storage of session of date time rule in the specific memory space, carry out to upgrade then when the time that arrives by the appointment of time on date and handle.Handle according to carry out this renewal based on the scheme of above-mentioned union.If the consideration rule feature is not then preferably used term of validity rule and date time rule to a session simultaneously.Preferably one of term of validity rule and date time rule are used with remaining service URI rule.
When while application service URI rule and date during time rule, the DVB-H receiving terminal only detects the session of having used the date time rule earlier, from this acquisition conversation ESG data, the ESG storage obtained in the specific memory space, and is handled being carried out to upgrade by the time of time on date appointment.
As mentioned above, because the detailed guideline of the ESG data by being provided for receiving dialogue-based division rule can receive the ESG data effectively, so the present invention can significantly improve the reception programme of DVB-H receiving terminal.
According to exemplary embodiment of the present invention, in the DVB-H broadcast service, provided the reception guideline that is used for the DVB-H receiving terminal according to the session division rule, thereby, even under a division rule or situation about existing, also the confusion in the reception operation that realizes the DVB-H receiving terminal can be minimized based on the compound rule of two division rules.According to exemplary embodiment of the present invention, the DVB-H receiving terminal can use division rule to carry out multiple function.
Although illustrate and described the present invention with reference to given exemplary embodiment of the present invention, but it will be appreciated by those skilled in the art that, do not exceeding under the condition of the spirit and scope of the present invention that limit by claims and content of equal value thereof, can carry out various variations in form and details here.
