Wireless video transmission system

Abstract

The invention provides a wireless video transmission system. The wireless video transmission system comprises a base station host, a wireless video encoder, a camera and a streaming media server. Thebase station host transmits an LTE signal to construct an LTE wireless network; the wireless video encoder receives an LTE signal transmitted by the base station host and forms wireless connection with the base station host. The streaming media server is electrically connected with the base station host. The wireless video encoder is electrically connected with the camera. The wireless video encoder converts a video of an SDI format or an HDMI format shot by the camera into an IP network video stream of an H.264 format or an H.265 format. The wireless video encoder transmits an IP network video stream in an H.264 format or an H.265 format to the streaming media server through the base station host. The wireless video transmission system provided by the invention adopts the protocol stack which is specially deeply optimized for video transmission, so that the video transmission is smoother, and the time delay is lower.

Description

technical field [0001] The invention relates to the field of wireless video transmission, in particular to a wireless video transmission system. Background technique [0002] Wireless video transmission systems are widely used in live TV broadcasting, webcasting, on-site wireless monitoring and other fields, but traditional wireless video transmission systems are based on 4G public network wireless transmission, and 4G public network wireless transmission has network bandwidth bottlenecks, especially In some large-scale sports, performances and other activities, a large number of 4G Internet access devices will make the bandwidth bottleneck of the 4G public network wireless transmission network more prominent, resulting in the inability of the wireless video transmission system to work stably, which greatly affects the live broadcast of the wireless video transmission system. Network live broadcast and on-site wireless monitoring and other functions; in addition, traditional...

[0002] Wireless video transmission systems are widely used in live TV broadcasting, webcasting, on-site wireless monitoring and other fields, but traditional wireless video transmission systems are based on 4G public network wireless transmission, and 4G public network wireless transmission has network bandwidth bottlenecks, especially In some large-scale sports, performances and other activities, a large number of 4G Internet access devices will make the bandwidth bottleneck of the 4G public network wireless transmission network more prominent, resulting in the inability of the wireless video transmission system to work stably, which greatly affects the live broadcast of the wireless video transmission system. Network live broadcast and on-site wireless monitoring and other functions; in addition, traditional wireless video transmission systems often work on a fixed frequency spectrum. Due to the large number of 4G Internet access devices at the event site, the use status of each spectrum at the event site is changeable. The traditional wireless video transmission system cannot scan the use status of each frequency spectrum at the event site, nor can it automatically select an optimal frequency spectrum, which will cause the wireless video transmission system to work in a crowded frequency spectrum and affect the stability of the wireless video transmission system. sex
