AI Technical Summary

Technical Problem

In traditional live streaming technology, when a packet is lost, the terminal device can only judge whether to retransmit based on the routing time between the streaming provider end and the terminal device, resulting in a degradation of the quality of live streaming service videos with high real-time requirements.

Method used

By storing the packet copy transmitted by the stream providing end in the wireless communication device, and when the terminal device issues a retransmission request, it is determined whether the packet copy exists in the memory, and directly provides the copy to the terminal device to avoid waiting for the stream providing end to be returned.

Benefits of technology

It improves the smoothness of videos in live streaming services, reduces the time when terminal devices wait for streaming to be returned to the terminal, and improves real-time and video quality.
