The invention discloses a method for improving reconstruction quality and a transmission rate of a video. The method includes the steps of determining a partitioning mode of a video stream in a current network environment according to the corresponding relation between a preset network environment and a video stream portioning mode; portioning the video stream into a plurality of sub-video-streams of various priorities according to the determined partitioning mode of the video stream; according to the priority of the sub-video-streams, after being processed by means of a coding and / or modulating mode in a corresponding protection degree, the sub-video-streams are transmitted outside through a wireless fading channel. The method improves the reconstruction quality and the wireless transmission rate of the video.
Description
technical field [0001] The invention relates to the field of wireless technology, in particular to a method for improving video reconstruction quality and transmission rate. Background technique [0002] With the development of indoor video applications, 802.11n can no longer meet people's needs with hundreds of Mbit rate applications. People pursue the application of Gbps (1024 megabits per second) required for indoor wireless high-definition video transmission to promote the development of wireless communication technology. [0003] Due to the limited wireless spectrum resources, the research on improving spectrum efficiency has always been one of the key topics in wireless communication, and in the wireless transmission of high-definition video, the amount of video stream data is huge, and the throughput requirements are very high. Therefore, in order to ensure the quality of video transmission Under the premise, spectrum efficiency is also one of the important considera...
