Description
Technical field
The present invention relates to filed of mobile multimedia broadcasting, refer more particularly to the sending method of electronic service guide table in the mobile multimedia broadcast system.
Background technology
In mobile multimedia broadcast system, ESG (Electronic Service Guide, electron service instruction) and user are directly mutual, operate on user's the terminal equipment, represent the navigation information of program.It not only can organize and television channel and the program that is provided is provided according to channel, but also program/content play time, program/brief introduction, program classification, the prize-winning briefing of program and program hot statistics rank are provided, or the like.
Make the user receive mobile multi-media broadcast program smoothly, need be with the timely broadcast transmission of the metadata of ESG to user's portable terminal, so that the terminal use selects and watch the program of oneself liking by ESG information.Because channel is many and program is abundant, and user's interest is varied, may need to send a large amount of ESG and show, how fast, efficiently and in time ESG is shown broadcast transmission and go out and become a problem.
Electron service instruction is made up of a plurality of tables, for example, traffic table and expansion table, contents table, service parameter table etc., each table comprises corresponding ESG metadata.Along with going deep into of business, the quantity of ESG table or the amount of information of each table also may constantly increase.The bandwidth of existing mobile multimedia broadcast system and the functions such as storage of portable terminal also are not enough to satisfy the requirement of system.Therefore, according to the characteristic of each ESG table, work out corresponding scheduling strategy, it is most important preferentially to send the ESG table that terminal needs most.
For example, the main information in the contents table is the information relevant with programme content, but also comprises the reproduction time of program.The user receives the schedule information that can represent program after this is shown on user's terminal.If this table broadcast transmission is in time gone out, the user just can not know current program and next program and their reproduction time thereof so.On the other hand, because the storage capacity of user terminal is limited, the quantity that terminal can the memory contents table is limited, therefore, will guarantee that at first the contents table that is about to play broadcasts away in time.
Secondly, the traffic table of ESG also comprises a professional expansion table.Usually, traffic table has been represented basic information, and its expansion table then is some additional information.Professional expansion table is no doubt important, but will hang down than its its importance of traffic table.
Again for example, the service parameter table comprises and professional relevant visit information, goes out if this shows not broadcast transmission, and then terminal can't receive ESG information, and the user just can not watch program.Moreover in general, the service parameter table does not generally change, even change, period of change is also very long, still, in case it changes, then must broadcast transmission go out, otherwise the user just can't use business in time.
The technical scheme that does not also address the above problem in the prior art, but how fast, efficiently and the ESG that in time terminal is needed most table broadcast transmission to go out be very necessary.
Summary of the invention
The objective of the invention is to, at above problem, a kind of sending method that is used for the mobile multimedia broadcast system electronic service guide table is provided, according to the factors such as time that the data variation frequency of different electronic service guide tables, significance level, requirement send, dispatch and the broadcast transmission electronic service guide table.

Embodiment
The present invention is described in more detail with example with reference to the accompanying drawings below:
As shown in Figure 1, the present invention adopts following steps to the scheduling strategy and the method for ESG table:
Metadata to ESG is classified, and sets up different ESG tables according to classification, comprises traffic table and professional expansion table, contents table, service parameter table and (program) layout table, and each table comprises corresponding ESG metadata.
Take all factors into consideration factors such as the importance of different ESG tables, the time that requires transmission, change frequency, formulate scheduling strategy, generate the scheduling queue of the broadcast transmission of ESG table.Described scheduling strategy specifically comprises:
1, according to the importance difference of ESG table, specifies the different broadcast transmission cycles, after refresh time arrives, in case during the broadcast transmission channel idle, guarantee that those important ESG show broadcast transmissions to user's terminal equipment.
2, the time that sends as requested generates scheduling queue, that is to say, the ESG table broadcast transmission which must should be sent in wanting seeking time is gone out; For example, generate scheduling queue according to the sequencing of the reproduction time of programme content, because more near the contents table of playing programs time, preferential more broadcast transmission is gone out; Otherwise the user can't browse programme distant information.
3, according to the change frequency difference of ESG table, specify the different broadcast cycle of ESG table, generate corresponding scheduling queue.The broadcast transmission cycle short (in order to guarantee the ESG metadata synchronization of portable terminal) of the ESG table that the broadcast transmission cycle of the ESG table that change frequency is higher is just low than change frequency.
The present invention has embodied following principle to the dispatching method and the strategy of ESG table:
(1) important more ESG shows preferential more broadcast transmission;
Important ESG table, be terminal equipment represent the ESG navigation information must be obligato.That is to say do not have these information users just can't use business.Should as early as possible they be sent to terminal, to reduce user's stand-by period.
(2) more near the contents table of the ESG of playing programs time, preferential more transmission;
For example, the contents table of ESG, it is theme, brief introduction and the content classification information of content not only, also comprises its reproduction time.Should guarantee before playing programs, preferentially these ESG tables be sent on user's the terminal that because have only the terminal reception and represented the information that these ESG show, the user can know the schedule information of program, could help the user to select the program that will watch.
(3), specify the broadcast transmission cycle (or repetition rate) of different ESG tables according to the different period of change of each ESG table;
The traffic table of ESG mainly comprises dynamic and important ESG metadata, and its expansion table then comprises static state (or quasistatic), inferior important ESG metadata.
Static (or quasistatic) data are meant that the ESG metadata does not change or almost indeclinable which ESG metadata, so the cycle of this class ESG table broadcast transmission more longer (because they change hardly).
Dynamic data is meant which ESG metadata that the ESG metadata often changes, thus the cycle of the broadcast transmission of this class ESG table to lack because will guarantee the ESG information of user terminal and the ESG metadata synchronization of transmitting terminal.
According to scheduling strategy of the present invention, the scheduling queue of generation neither be changeless, but can dynamically adjust and upgrade according to the variation of data.
As, when ESG table took place to upgrade, important ESG table that should preferentially which have been upgraded or ESG that must broadcast transmission is gone out in requiring transmitting time showed, in case during the broadcast transmission channel idle, even also not to the refresh cycle, also they broadcast transmissions to be gone out; Remaining ESG table had only after the time that has arrived the broadcast transmission cycle, and just broadcast transmission is gone out.
Fig. 2 for the present invention to a kind of update mode schematic diagram of scheduling queue, be that the priority of the ESG table that will send is reduced to minimum.
After scheduling queue upgraded and adjust, continue to send according to above-mentioned strategy and step.So periodic transmission has made full use of the resource of broadcast channel, make ESG information that the user needs most in time broadcast transmission on user's terminal.
The present invention is the importance of having taken all factors into consideration different ESG tables, time, the change frequency that requires transmission, the performance of terminal equipment and the factors such as limitation of battery life have also been considered, generate the scheduling queue of the broadcast transmission of ESG table, rather than simply the ESG metadata is divided into the different cycles, after arriving its cycle time of broadcast transmission, just broadcast these ESG metadata.According to the present invention, which ESG table important and must broadcast transmission is gone out in requiring transmitting time of preferential broadcast transmission.Equally, when the ESG metadata send to be upgraded, which ESG table important and must broadcast transmission is gone out in requiring transmitting time of timely broadcast transmission, the ESG information that guarantees user terminal is synchronous in real time with transmitting terminal.
The invention provides and a kind ofly in mobile multimedia broadcast system, show the terminal of preferential broadcast transmission with the fast ESG of change frequency to the user with important, and the broadcast transmission cycle that ESG table that will be almost constant is set is longer, reduced requirement like this, guaranteed the performance of system again the broadcast transmission bandwidth.
Method provided by the invention has reduced the transmission number of times of static (quasistatic) data, avoids terminal equipment owing to frequently receive these ESG tables and consuming cells too much, and the reduction of performance.
