II ---; .- Description of the invention (1) Application field of the invention The invention relates to a kind of data transmission in the Data on Digital Broadcasting (DAB) is transmitted, especially an application [Background of the Invention] A method of presenting beehive. The broadcasting system used by Mu Jing mainly refers to a broadcasting system and system, that is, the existing pacing system (FMM = analogue broadcasting system using a class player t-dagger system). The channel of the analog broadcasting system is fixed and the bandwidth is wide (AM). Channels, because of the information, and one channel can only accommodate two; ^ can be used to transmit sound when two or more channels are close, often the transmission of immediate information, when there is interference; plus the coverage of analog broadcasting = ^ When the boundary of the dry coverage area between the two channels of production land is due to the sound of the signal = the device on the receiving end is often flooded with a lot of noise. It does not matter that the receiving end receives modern communication technology. It is said that in order to discontinuous signals; designing a new transmission system has become increasingly important to meet the needs of human beings. In addition, most of the current broadcast ecology. Film delivery, modern biomass for high-speed information transmission and exchange = data It is difficult to integrate the transmission between the sender and the receiver: f unidirectional transmission methods have gradually become weaker. In addition, in terms of the first two uses of 2 tsf this multimedia information mode, It can transmit multimedia information. ^ ^ = There is still room for improvement in terms of speed, range, and amount of data. Purpose and Summary of the Invention] In view of the problems of the conventional technology above, the present invention provides an application for digital broadcasting ( The method of data transmission and data presentation on DAB) is a method of transmitting data through digital broadcast (DAB) packet transmission technology from the transmitting end to the receiving end through the transformation of the data and the conversion of the packet technology.

ί The uncle performs frequency modulation on the orthogonal frequency division multiplexing processor. It is transmitted by transmitting: 1 material, which is the base 2 generated by the digital broadcast (DAB) signal. The digital broadcast signal is mainly passed through a series of The packet conversion is formed by the cutting of the spoon, and the formation process is mainly divided into three types: wireless transmission, identification, formation of multimedia data transmission objects (M0T 0bject), and cutting of fish = system data transmission objects (MOT Object). Part; in the formation part of each transmission packet, since the wireless transmission packet is composed of the main data area Γ〇Π Air * C. £ ·,

Air bpeciflcatlon Message), start information (T〇tal Length) and data classification code (capCoc [e) (as shown in r attachment 2 ^) 'The data to be transmitted must pass through the format of this packet before it can be carried 'And this data is mainly entrained in the main data area (〇I1 Air

Specification Message). However, due to the different types of data, the layout of the main data area is also different, and can be divided into three categories; the first category is shown in "Appendix III" and "Appendix IV". The information (Checksum) and data group header (Data Group Header) are composed of three sub-data areas. The data of this type of application are mostly data types such as the generation or name of the data; the second major category is shown in "Annex V" It is mainly composed of four sub-data areas: Data Group Header, Package Header, Package Data, and Checksum. The data of this type of application are mostly long message types. The third largest category is shown in "Annex 6", "Annex 7", "Annex 8", "Annex 9", "Annex 10" and "Annex 11"), which are mainly composed of data group header blocks ( D ata G r 〇up Header), time format

569563 MM 91116794 V. Description of the Invention (6) The data block (Leading Data), the time-related data block (Data Group Data) and the end information block (checksum) are composed of four sub-data blocks. Most of the data are related to time. It can be seen that the main data area can be classified into three categories, and even the third category is further divided into four variants. However, after a summary analysis, we can know that the main data area of the Xuanxuan is composed of the Group Data) and the checksum. ) And a Data Group Header (Data Group Header). In the forming part of the multimedia data transmission object (MOT 〇b ject): As shown in "Attachment 12", "Attachment 13" and "Attachment 14", after the formation of the wireless transmission packet, the data is not yet available. When transmitting in the digital broadcast (dab) transmission mode, it still needs to go through a conversion process before transmitting in the digital broadcast (DAB) transmission mode, and "Annex 12" and "Annex 14" are used to display wireless transmission packets Through the various modules in the figure, processing to form a multimedia data transmission object (MOT OBject). As for "attachment ^ 13", it is more clear to indicate which branch groups a wireless transmission packet passes. Operates to form the multimedia data transfer object (

Object). ^ Cut part of multimedia data transmission object (M0T 0bject): Afterwards, although the multimedia data transmission object (MOT Object) ^ pay & digital broadcast (DAB) transmission mode, if you want to directly media data transmission object ( M〇T 〇b ject),

"Appendix XV" is used to introduce the structure of multimedia data transmission objects (m〇t 〇b 彳 "7); the structure of multimedia data transmission objects (Mot 〇bject) is mainly composed of header core area The header control is composed of the "Heart factory extension" area and the object body (〇bject b〇dy) area. In the header header area described above, the information content includes information about the size and type of the object, which enables the receiving device to decide whether to decode or display ^; header extensi〇n ^, The content of its tribute contains information about the control object, such as memory control and some additional information, to provide the use of various applications; the object body area (Object body) area, the information content is the information itself, used to Provide this information. Then talk about the theme of the cutting part of the multimedia data transmission object (MOT 〇bject), as shown in "Annex 16", the multimedia data transmission object (MOT Ot ^ ect) is carried out according to the header and the object body Divide, divide ^ multimedia objects into "attachment 17". This multimedia object is then cut into a digital broadcast (dab) packet mode, and then the digital broadcast (DAB) is used to transmit the digital broadcast (DAB). ) Packet transmission = After studying the multimedia data transmission object (M0T 0bject) and the object and packet structure of the wireless transmission packet, continue to explain how to Some objects are transmitted. Currently, there are three types of multimedia object transmission methods used in digital broadcasting (DAB). One is the object repeat transmission mode. As shown in "Annex 18", the multimedia objects are first cut into four digits. Broadcast (DAB) packets, and then repeatedly transmit the multimedia objects in the order of number. An object cross-transmission mode, as shown in "Annex Nineteen", transmits several digits simultaneously in the same data channel (single data channel). Guang 569563. Year V :, Sun Shuangzheng ί Bu Wu No. 91116794_year month day_Hi_ V. Description of the invention (8) Broadcast (DAB) packet; One is the repeat transmission mode of fragments, as shown in "Annex 20" , First cut the multimedia object into four digital broadcast (DAB) packets, and then repeatedly transmit a segment of digital broadcast (DAB) packets several times according to the number sequence; therefore, the operation of the three transmission methods can increase the correct transmission of multimedia objects And stability.

Although the present invention is disclosed in the foregoing preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some modifications and retouching without departing from the spirit and scope of the present invention. The patent protection scope of the present invention shall be determined by the scope of the patent application scope attached to this specification.
