Abstract
The invention relates to a grouping broadcasting method based on broadcast. The working steps comprises four steps, firstly, groups are established for a terminal; secondly, a front end informs the terminal to enter a certain real group or a certain virtual group through editing an event, namely group entering event; thirdly, treatment of the event is judged by the terminal whether the event belongs to the corresponding group after receiving the event, fourthly, an identical event of the terminal is required to execute a plurality of events, to judge priority rates and to implement the event with high priority rate. The grouping broadcasting method has the advantages that groping control of the terminal is realized, different tasks are respectively implemented by assigning terminal of each group within the specified time, namely events, the events can request the terminal to broadcast real time programs within the presetting time, or to broadcast local files, or to perform immediate downloading etc, so as to satisfy different demands oof different clients, or different demands of identical clients within different time.
Description
Technical field
The present invention relates to a kind of data broadcasting field, control method is broadcasted in particularly a kind of grouping based on broadcasting.
Background technology
High speed development along with digital television techniques, people have produced the demand of new personalization to the data broadcasting service, wish to select to adapt to the broadcast program of hobby separately, and the vehicle-mounted digital television of current extensive use or building TV etc. can only receive and play same data message, can't segment and classify at different environment and customers, and then play the content that adapts.
Summary of the invention
Technical problem of the present invention is that a kind of control method that terminal is divided into groups to broadcast will be provided, realization is to the grouping control of terminal, appointment is respectively organized terminal and carry out different separately incidents respectively in special time period, incident can be that the requirement terminal is play real time programme in the Preset Time section, also can play local file, can also download immediately etc., satisfying different different requirements of customers, or the same different demands of client in different time sections.
Introduced the notion of group in the present invention,, terminal has been divided, allowed different groups realize different business by " group ".And in order to reach the purpose of flexible management, again component is become two kinds, promptly real group and empty group.So-called real group is exactly the group that terminal is just distributed when dispatching from the factory, and this group can not change arbitrarily; And empty group is exactly can be by the group of the dynamic designated terminal adding of coded system, and the terminal that comprises in this group can be changed as required at any time.
As shown in Figure 1, the hierarchical structure of group is represented with a binary tree, leaf node GC group connector in the binary tree, and remaining node all is a group, and group has the notion of priority, and the priority that regulation has from the near more group of leaf node is high more.Use the priority height of the real group of demonstration that the level of node in binary tree can image, the priority of real group is that the node level adds 31, and promptly the level of root node is 0, and its priority is 31 so, and priority is minimum; The level of leaf node is 3, and its priority is 34, and priority is the highest.In the actual coding system, binary tree always has 33 layers, i.e. the real group priority of root node representative is 31, and the priority of the terminal of leaf node representative is 63.Have inclusion relation between the real group, i.e. the reality group of father node representative comprises the real group of child node representative.The reality group of root node representative is father's group of all real groups.
Distribute a reserve area and organize as void in binary tree, each node in this piece zone all is an empty group.By the layout of coded system, any one or a plurality of real group can join same empty group, and all terminals in this moment these real groups also just belong to this empty group, do not have set membership between the empty group.Can specify the priority of empty group during layout void group, the empty scope of organizing priority is 0 to 30, and promptly the priority of empty group always is lower than the priority of real group.By void group can real realistic set flexible group and, to satisfy different service needed.
In order to solve above technical problem, the invention provides a kind of grouping and broadcast control method based on broadcasting, the job step of this control method is:
1) is terminal establishment group, deposits in Groups List;
2) front end adds incident, the group of selection incident correspondence and the type of incident from Groups List;
