Problems solved by technology

First, the calculation cost required to recover errors is high; second, it is required to set up additional logic for error detection and recovery at the receiving end, so it is difficult to be widely used; third, when errors occur in one interval, even if Errors are detected and the probability of correction is not high, so it is weak to burst errors (Burst Error)

Abstract

Provided are a data transmission method, the method comprises transmitting data from a data transmission apparatus to a data reception apparatus, selecting time difference retransmission target data from the data according to a preset rule by using the data transmission apparatus, determining a retransmission time interval according to characteristics of the time difference retransmission target data by using the data transmission apparatus, determining whether time difference retransmission is possible based on the state of a network when the retransmission time interval arrives by using the data transmission apparatus and retransmitting the time difference retransmission target data to the data reception apparatus when determining that the time difference retransmission is possible by using the data transmission apparatus.

Description

technical field [0001] The invention relates to a data transmission method and device. In more detail, it relates to a data transmission method and device for preventing transmission delay and service quality degradation caused by data packet loss when transmitting data to a data receiving device. Background technique [0002] Providing various services through an IP network has the advantage of maximizing transmission efficiency, but has the disadvantage of not being able to guarantee a predetermined level of service quality. This kind of problem is caused by best effort (Best Effort), which is an essential characteristic of IP services, so it is not easy to fundamentally solve this problem as long as services are performed through an IP network. [0003] Services such as web pages or file transfers are based on data that is not sensitive to the time of delivery, so service quality is not considered a major issue. However, in video on demand (VOD, Video On Demand) service...
