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] like 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 ac...

Abstract

The present invention relates to a data encapsulation method and system matching multiple transmission modes. The method includes: step 1, dividing business data into fixed-length fragment files; step 2, dividing the fragment files and auxiliary Data interleaving is added to the broadcast queue; step 3, the fragmented file is encapsulated into multiple UMCP blocks, and it is judged whether to add data verification to the UMCP block according to the link quality; step 4, according to the needs of network adaptation, one or more A UMCP block is encapsulated into a network protocol frame. The present invention simplifies the data segmentation process through fixed-length slice preprocessing, realizes multi-channel concurrency of business data, improves broadcast efficiency, and improves transmission reliability through mixed broadcast and verification functions of business data and auxiliary data , realize the selective reception of data through business requirements, improve business flexibility and reception efficiency, and can adapt to a variety of data link layer network protocols to realize cross-network collaborative services under different network conditions.

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...
