step a, receiving the data to be transmitted, acquiring a data identifier and a data parameter transmission type in the data to be transmitted, classifying the data to be transmitted by combining the data identifier and the data parameter transmission type, and determining a data type corresponding to the data to be transmitted.
Specifically, the digital broadcasting system receives data to be transmitted sent by an upper layer application, then obtains a data identifier of a link layer interface in the data to be transmitted, determines a service type corresponding to the data to be transmitted according to a preset data mapping table in the digital broadcasting system, then obtains a data parameter transmission type in the data to be transmitted, classifies according to the service type and the data parameter transmission type, and determines a data type corresponding to the data to be transmitted.
The link layer interface is a part of a data format in data to be transmitted. The preset data mapping table is preset in the digital broadcasting system according to requirements, and the embodiment is not limited. The data parameter transmission types include, but are not limited to, system information packet transmission, user message packet transmission, service flow transmission, and service packet transmission, wherein the system information packet transmission and the user message packet transmission belong to message packet transmission. Message packet transmission is applied to the transmission of various types of message data. Both service flow transmission and service packet transmission are applied to the transmission process of service data. The service stream transmission is applied to a scene without integrity detection of data to be transmitted in the data transmission process. The service package transmission has certain structurality, can carry out integrity detection on the received data to be transmitted, and is mainly applied to scenes that the data to be transmitted is sensitive to data loss and accuracy in the data transmission process.
It should be noted that the data format of the data to be transmitted is data identifier + data length or data number + data transmission control parameter domain or upper application control parameter domain + data transmission system parameter domain or data content domain.
In this embodiment, for example, the preset mapping relationship between the data identifier and the service type in the data mapping table is system configuration information corresponding to the data identifier 0x00, message data corresponding to the data identifier 0x01, and service data corresponding to the data identifier 0x02, the data identifier in the data to be transmitted received by the digital broadcasting system is 0x01, the transmission type of the parameter of the data to be transmitted is obtained as user message packet transmission, and the digital broadcasting system determines that the data type of the data to be transmitted is received as user message.

After the digital broadcasting system determines the data type corresponding to the data to be transmitted, the packaging format code corresponding to the data to be transmitted is determined according to the mapping relation between the data type and the packaging format code in the digital broadcasting system, then the data packaging format corresponding to the data to be transmitted is determined according to the mapping relation between the packaging format code and the data packaging format in the digital broadcasting system, and then the data to be transmitted is converted into the data packaging packet corresponding to the data packaging format.
It should be noted that, the mapping relationship between the data type and the package format code in the digital broadcasting system, and the mapping relationship between the package format code and the data package format in the digital broadcasting system are preset in the digital broadcasting system, and the embodiment is not limited.

The mapping relation between the package format code and the data package format in the package format mapping table is that the package format code 1 corresponds to a system message package format, the package format code 2 corresponds to a user message package format, and the package format code 3 corresponds to a service flow package format and the package format code 4 corresponds to a service package format. And if the data type of the data to be transmitted acquired by the digital broadcasting system is the user message, determining that the packaging format code of the data to be transmitted is 2, and the data packaging format is the packaging format of the user message package.
D, if the data packaging format is a message packaging format, converting the data to be transmitted into a message packaging packet;
and e, if the data packaging format is a service flow packaging format or a service package packaging format, converting the data to be transmitted into a service packaging packet.

If the digital broadcasting system detects that the data packaging format of the acquired data to be transmitted is a service stream packaging format or a service package packaging format, the data to be transmitted is converted into a service packaging packet corresponding to the data packaging format. The message package packaging format comprises a system message package packaging format and a user message package packaging format, and the corresponding message packaging package comprises a system message packaging package and a user message packaging package.

and step i, if the first residual capacity is detected to be absent, the message encapsulation packet is encapsulated to a second message subchannel.
Specifically, referring to fig. 5, fig. 5 is a message packet encapsulation rule of the present invention, if the digital broadcasting system detects that the data encapsulation format is the message packet encapsulation format, the digital broadcasting system determines that the data encapsulation packet is the message encapsulation packet, and determines that the data encapsulation rule is the message packet encapsulation rule, the digital broadcasting system obtains the remaining capacity of the message channel, and detects whether the remaining capacity is greater than or equal to the first byte length of the message encapsulation packet, if the remaining capacity is greater than or equal to the first byte length, it detects whether the first remaining capacity exists in the first message sub-channel, and if the remaining capacity is smaller than the first byte length, it encapsulates the message encapsulation packet into other message channels whose remaining capacity is greater than or equal to the first byte length. If the residual capacity is detected to be larger than or equal to the first byte length and the first residual capacity is detected not to exist, the message encapsulation packet is encapsulated to the second message sub-channel, if the first residual capacity is detected to exist, the first byte length is divided into the first message encapsulation packet with the size equal to the first residual capacity, the first message encapsulation packet is encapsulated to the first message sub-channel, and then the residual second message encapsulation packet is encapsulated to the second message sub-channel.

And if the first service encapsulation packet is detected to be absent, directly encapsulating the service encapsulation packet to the first service sub-channel.
It should be noted that, when the remaining payload length of the service encapsulation packet is greater than or equal to the length of the corresponding service subchannel, the size of the service flow encapsulation is defined as the length of the service subchannel. One traffic encapsulation may encapsulate multiple traffic encapsulation packets.
