As shown in FIG. 3, the method includes the following technical steps:

S302, Edit and maintain ESG data. Includes management and maintenance of various types of ESG raw data information.

The ESG raw data may include several ESG data information, ESG basic description information, program prompt information, and may also include ESG value-added service data. The ESG data information includes service information, service extension information, scheduling information, content information, and service parameter information data related to the mobile multimedia broadcast service.

The ESG broadcast data scheduling parameters include: Specify the ESG broadcast data transmission priority, the transmission data section size, the transmission frequency, and the like.

S306. Generate ESG broadcast data. According to the generation parameters of the ESG system configuration data, the ESG original data is encapsulated according to a certain format specified by the protocol to distinguish the ESG broadcast data and generate data for broadcast transmission. The system can select one or more parts of the ESG raw data according to the configured generation parameters. Or all, used to generate ESG broadcast data.

S308. Schedule and send ESG broadcast data. The broadcast transmission process of executing one or more ESG broadcast data is scheduled according to the scheduling transmission parameters of the ESG system configuration data. The system controls the sending priority of the ESG broadcast data, the size of the sending data block, the sending frequency, etc. according to the configured scheduling parameters, and sends the ESG broadcast data to the transcoding/multiplexer. 4 is a schematic diagram of an ESG broadcast data package according to an embodiment of the present invention. As shown in FIG. 4, the ESG broadcast data encapsulation corresponding to the ESG scheduling transmission system is shown. The data unit is the data organization unit that the ESG generator sends the ESG broadcast data, and the parts of the package are defined.

An 8-bit field indicating the data block to which the data section belongs. Data type identifier

A 4-bit field that identifies the type of data carried by the data payload, as defined in Table 1, and uniquely identifies a block of data along with the data block label i.

ESG data type

When multiple ESG data types are selected to generate a unified ESG broadcast data file, the attribute can use the reserved value when sent. For example, 0000 ( B ), indicates a mixed data type. Therefore, when distinguishing data types from being sent, ESG The broadcast data file generally only selects one type of information of the ESG data type, and when it is sent, the attribute fills in the value of the corresponding data type. For another example, 0110 (B) can be used to represent a deterministic hybrid data type, including service information and service parameter information. For example, an ESG broadcast data file is generated from business information and business parameter information that do not change frequently and have a small amount of data. A large number of arrangement and content information are separately scheduled and sent. For another example, a large amount of programming information needs to be divided into different ESG broadcast data according to the time period, and an ESG broadcast data file is generated by the most recent two-day programming that the user cares most. Another ESG broadcast data file is generated for another 5 days of the week. The former transmission priority and transmission frequency can be appropriately increased. Coding type

3-bit field, indicating the compression encoding type used by the ESG data payload, see Table 2. Table 2 coding type

The GZIP compression coding is compressed by the GZIP compression algorithm, see IETF RFC 1952. Section number

8-bit field, ranging from 0 to 254, indicates the section number of the currently transmitted data. Total number of sections

8-bit field, ranging from 1 to 255, indicating the total number of nodes carrying the currently transmitted data. Data payload

The ESG data information is described by the ML method. The XML data is divided into data blocks according to the data type and data identification, and the block is divided into data sections according to the requirements of the transmission unit. This field is the payload carried by the data section. The length of the data payload N needs to be calculated based on the length of the data unit of the multiplexed subframe, and is calculated as follows:

N = multiplex sub-frame data unit length - data header length - CRC_32 length

CRC-32

32-bit field, CRC-32 decoding model see Appendix A of GY/T 220.2-2006. When scheduling transmission, the "data block identifier" corresponds to different ESG broadcast data files; the "data type identifier" corresponds to the ESG data type included in the ESG broadcast data. Therefore, the terminal can selectively receive and process ESG data information according to the degree of need for ESG data information and the timing of presentation. In the mobile multimedia broadcast system provided by the present invention, the ESG scheduling and sending method can conveniently implement the generation and scheduling of the ESG broadcast data to meet the needs of the business application, and can improve the user experience. The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes can be made to the present invention. Any modifications, equivalents, and substitutions made within the 4th principles and principles of the present invention? Wenjin et al. are intended to be included within the scope of the present invention.
