Embodiment Construction

[0048] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0049] Such as figure 1 As shown, this embodiment provides a data encapsulation method that matches multiple transmission modes, and the main steps include:

[0050] Step 1. Divide business data into fixed-length fragment files;

[0051] Step 2, according to the broadcast plan, add the fragment file and the auxiliary data corresponding to the fragment file to the advertisement queue, and adjust the priority of adapting and broadcasting the fragment file;

[0052] Step 3, encapsulating the fragmented file into multiple UMCP blocks, and judging whether to add data verification to the UMCP block according to the link quality situation;

[0053] Step 4: Encapsulate one or more UMCP blocks into a network protocol frame...

Abstract

The invention relates to a data packaging method capable of matching multiple transmission modes and a system. The method comprises steps: S1, service data are divided into fragmented files with fixed lengths; S2, according to a broadcasting plan, the fragmented files and auxiliary data are added in an interleaving mode in a broadcasting queue; S3, the fragmented files are packaged into a plurality of UMCP (Unit Multi-Cast Protocol) blocks and whether data check is added to the UMCP blocks according to the link quality condition; S4, one or more UMCP blocks is packaged into network protocol frames according to the needs of network adaptation. Through carrying out pre-treatment on the fragmented files with fixed lengths, the data dividing process is simplified, service data concurrence in multiple channels can be realized, the broadcasting efficiency is improved, reliability of transmission is improved through mixed broadcasting of service data and auxiliary data and the check function, selective data receiving is realized through service needs, service flexibility and receiving efficiency are improved, the method can be adapted to multiple kinds of data link layer network protocols, and cross network collaboration service in different network conditions can be realized.

Description

technical field [0001] The present invention relates to the field of multimedia broadcasting technology, in particular to a layered data encapsulation technology for the integration of one-way network and two-way network, specifically a technology that divides the content and session of the application layer into basic multicast transmission data blocks, and realizes A data encapsulation method and system matching multiple transmission protocols of the lower transport layer. Background technique [0002] Below are some nomenclature explanations in this area, and its scope of use is limited to the present invention: [0003] MBIS: Multimedia Broadcast Interactive System interactive multimedia broadcasting system; [0004] UMCP: Unit Multi-Cast Protocol, unit multicast protocol; [0005] UCL: Uniform Contents Locator, unified content positioning; [0006] OTT TV: Over-The-Top TV, that is, a two-way network TV served in the Over-The-Top mode; [0007] DVB-C: Digital Video B...
