Data release and reception method based on self-adaptive complementary mechanism

Abstract

The invention belongs to the field of the integration network technology and particularly relates to a data release and reception method based on a self-adaptive complementary mechanism. The data release and reception method based on the self-adaptive complementary mechanism aims to make up for disadvantages caused by power-law distribution characters presented in the process of internet access and broadcasting network transmission undirectionality and enable the internet and the broadcasting network to cooperate. The method includes the steps of putting forward the self-adaptive complementary mechanism, issuing large-scale data in a circulating mode through a broadcast channel, ensuring the speedability of information transfer, and requesting package compensation through an internet channel on the premise that error codes exist in the broadcast channel so as to ensure data integrity. Through the method, data retransmission time caused by the channel error codes can be reduced, and the method makes up for the disadvantage that the data are transmitted through the single channel, and promotes user experience.

Description

technical field [0001] The invention belongs to the technical field of fusion network, and in particular relates to a method for publishing and receiving data based on an adaptive complementary mechanism. Background technique [0002] With the continuous progress of society, people's demand for material and cultural life is also increasing. In the field of information technology, traditional Internet services can no longer fully meet the needs of users, and large data volume transmission services such as high-definition movies and video-on-demand are increasingly favored by users. [0003] The current major transmission networks, such as cable Internet, radio and television networks, etc., cannot independently meet the needs of users for large data transmission services. Wired Internet is limited by bandwidth, and it takes a long time to transfer large files, and its access form obeys the Power-law distribution, which can easily cause network congestion; although broadcast...

AI Technical Summary

Problems solved by technology

In the field of information technology, traditional Internet services can no longer fully meet the needs of users, and large data volume transmission services such as high-definition movies and video-on-demand are favored by more and more users

[0003] The current major transmission networks, such as cable Internet, radio and television networks, etc., cannot independently meet the needs of users for large data transmission services

Wired Internet is limited by bandwidth, and it takes a long time to transfer large files, and its access form obeys the Power-law distribution, which can easily cause network congestion; although broadcasting and television networks have sufficient bandwidth, they are unidirectional networks , unable to exchange information with users, only forward error correction (FEC) can be used for multiple transmissions to ensure service quality, and the efficiency is low

At the same time, the resources of the broadcast network are relatively scarce, and it is difficult to attract users

[0004] In the case of the above-mentioned single network, the service quality and efficiency are low, which cannot meet the needs of users
