Description
Technical field
The present invention relates to electron service instruction (ESG) program prompt information, refer more particularly to the transmission method of electron service instruction program prompt information (or programme distant information) in the mobile multimedia broadcast system.
Background technology
In mobile multimedia broadcast system, the function of ESG is the relevant information that mobile multi-media broadcasting service is provided for the terminal use, as Business Name, reproduction time, content outline etc., is convenient to quick retrieval and the visit of user to business.It is made of basic descriptor, data message and program prompt information.
Program prompt information is the supplementary of ESG, has described the summary info of professional current slot and next time period broadcast program, with multimedia broadcasting look, audio unit transmits in service logical channels.
Data message is the main body of ESG, be packaged into the data cell of multiplexed sub frame, transmission for the adaptation service logic channel, data message is divided according to type, be divided into business information class, arrangement information class, content information class and business parameters data class etc., distinguish by the data type identification field; Sorted data message is cut apart by piece, distinguished by the data block identification field; Data block is divided into some joints, distinguishes by the joint sequence number field, and data section is corresponding one by one with the data cell of multiplexed sub frame.In normal circumstances, according to the method, the ESG program prompt information (or programme distant information) that portable terminal is received, be in the different info class of two different ESG data messages, therefore, need broadcast transmission and receive a large amount of ESG data messages, this is extremely disadvantageous concerning terminal.
The method of the ESG program prompt information (or programme distant information) that the existing patent documentation and the standard of having issued are introduced, all the layout element with the content element of the content information class of ESG data message and its arrangement information class is separated from each other (be in the arrangement information class not the information of content info class).May be because the arrangement information class of program be huge and/or the content information class of program is big and many, the resource that can consume portable terminal too much.And computational resource and the memory capacity of working as portable terminal are limited, also are difficult to store in internal memory the data message of all ESG.
The low memory that one of problem is portable terminal then have to stop at the data message of storing ESG in the internal memory with the data message of storing all ESG or when having exceeded certain thresholding.The information of the content information class of its adverse consequences that causes is a mobile terminal stores all programs, and only stored the wherein information of part arrangement information class.At this moment, portable terminal can only use the content of " part " program of having stored, because it has lost the information of arrangement information class of the content of corresponding some program.In fact, the content information of program of having lost the information of arrangement information class has but occupied the memory space of a large amount of preciousnesses of portable terminal.If the content information class of program is broadcast transmission at first, similar phenomenon also can take place, and has promptly lost the information of the content information class of some program, and has stored the information of the arrangement information class of all programs.
Another problem is that during the broadcasting of ESG data message, if broadcasting transmits interruption and the wireless digital broadcasting bandwidth is not enough, then Xiang Guan phenomenon also can take place.In this case, problem is not that the internal memory of portable terminal is too little, but the broadcast transmission of the data message of ESG has been interrupted.The data message of the ESG that is stored is if complete, and then it is available.And in such cases, the data message of a large amount of ESG that has received is incomplete, that is to say it is that data message disabled, ESG in other words is useless.
For this reason, design the structure of the ESG program prompt information (or programme distant information) that can either fully describe media content, can not take too much wireless bandwidth again, when receiving these data, its portable terminal considers the performance of its terminal and the length of its battery life again, especially the design and the realization of the content information class of program and its arrangement information class are one and have challenging task.It has become the important topic that the structural design aspect of mobile media broadcasting network ESG program prompt information (or programme distant information) especially must solve.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of transmission method of program prompt information (or programme distant information) of electron service instruction, described method can send program prompt information to portable terminal to realize the function of TV guide, can be reduced in the shared bandwidth of program prompt information in broadcasting transmission and the portable terminal receiving course simultaneously.
Further, described method can fully be described the ESG program prompt information of media content, reduced broadcasting transmit and the portable terminal receiving course in the losing of useful information in the ESG program prompt information, can directly increase the useful information amount in the ESG program prompt information of portable terminal.
In order to address the above problem, the present invention proposes a kind of transmission method of program prompt information of electron service instruction, described method comprises:
The program prompt information of described electron service instruction is encapsulated in the data cell of multiplexed sub frame, with Mobile Multimedia Broadcasting look, audio service transmits;
When the data type of the data cell of multiplexed sub frame was " program prompt information ", what represent that this data cell carries was program prompt information; As long as terminal receives the programme distant information that described program prompt information just can be realized electron service instruction;
Wherein, the data unit information of described electron service instruction program prompt information comprises one or more in record number, reservation, time started, duration, category of language, theme length, theme and the CRC_32 field.
Further, described record numerical table shows the program prompt information quantity that the notebook data unit comprises, and article one is recorded as current program information; Be left and keep the position; Time started comprises program start time and the date of representing with UTC and MJD form; Duration is the reproduction time length of interior perhaps program, and unit is second; The used language of category of language explanation back the text field; Theme length is represented the length of theme; The title of broadcast program content represented in theme; CRC_32 is 32 bit fields.
Compared with prior art, the present invention proposes a kind of transmission method of programme distant information of electron service instruction, can be reduced in that broadcasting transmits and the portable terminal receiving course in broadcast bandwidth in the ESG program prompt information, directly increase the useful information amount in the ESG program prompt information of portable terminal.Take into full account characteristics such as the limited and battery life of terminal capability, promoted the reliability of system.
