Be defined in EMS now and broadcast the strategy of broadcasting Section in the server 104.Originally the strategy of SMS notification system is that all group Section are sorted, and discharges the highest N group (configurable) of priority, broadcasts away, and sort algorithm is fast row.Owing in system of the present invention, preserved the message content of each group or channel, therefore to broadcast at every turn and just be not suitable for adopting fast row, and should adopt method for screening to realize, specific algorithm is as follows:
Take out this time and broadcast the highest Section of priority, obtain its SendLevel and its position in tabulation
Traversal Section tabulation is taken out and is approached (or equaling) last time Section of priority most, its position in tabulation of getting back;
Circulation N time is all approached most (or equaling) last time Section of priority at every turn.
All Section data structures that obtain are broadcast in this time be packaged into Section, send to DS.
In addition, data broadcast navigation system of the present invention is also carried out following operation.
1. broadcast the bulletin instruction
At first generate a bulletin instruction, can generate this message by the EMS client software;
If defined 100 video channels in the epg database, this announcement message will be copied into 100 message simultaneously so, the MessageID field value of every message all is identical, unique different be the ServiceID field, represent that each channel all can have an announcement message, the priority of each bar message all is 65535 (system's predefineds);
If 20 message are only broadcast in EMS broadcasting system definition at every turn, once to broadcast in the cycle so, broadcasting system will sort to 100 message, take out the highest 20 of priority, be transferred to DS;
After inferior 20 message were broadcast away, the priority that is had subtracted 1, prepared to broadcast next time.
When broadcasting, once more 100 are sorted next time, take out the highest 20 of priority, broadcast once more;
After 5 times, the message of all channels has all been broadcast away, and this moment, broadcasting system did not stop, and it still sorts and broadcasts, up to new information arrival or by expired cleaning.
2. set-top box receives the bulletin instruction
When set-top box enters a new video channel, it will start a filter, and the filtercondition of this filter is as follows:
ServiceID﹠amp; VersionNumber promptly has the announcement message of identical ServiceID in it detects TS stream, and VersionNumber changes, and it will receive message so;
Change when set-top box detects VersionNumber, it will accept this message, and this moment, it did not show, because set-top box and do not know whether this message showed;
Set-top box can obtain the MessageID value of this message, and it judges the MessageID value whether this value preserved greater than oneself, if, represent that then this message is new information, if not, represent that then this message showed, no longer show;
If new information, then it resolves follow-up parameter, and for example displaying contents, display position, rolling duration, preceding background color etc. show at the assigned address of television screen.
3. individual people's instruction process
Individual's instruction is identical with the Processing Algorithm of bulletin instruction, and difference is that announcement message is that all set-top box all receive, and personal messages need add a StbNo field, and expression receives message at single set-top box.
The algorithm that personal messages is broadcast is consistent with bulletin, is not described in detail in this.
The number of set-top box of personal messages is 16 binary-coded decimals, the number of set-top box character representation of 0-9, so it can represent to be up to 16 number.
When set-top box received personal messages, the filter conditions that rises was: ServiceID﹠amp; StbNo﹠amp; VersionNumber promptly represents to have in the TS stream message of identical ServiceID, StbNo, and VersionNumber just goes to receive message when changing.
Judge in the TS stream that whether the mechanism of new information is identical with the judgment mechanism of announcement message, be not described in detail in this.
The service code that individual instruction is entrained must be consistent with the entrained service code of bulletin instruction, and this individual instructs entrained page address just can be opened by the navigation system of set-top box, otherwise set-top box will be thought this individual's instruction ignore, not display page.
In addition, the data broadcasting navigation is to adopt the technological means of EMS to realize the automatic triggering of L screen.Wherein,
