Embodiment 1
[0027] In the environment of wireless networks (such as mobile communication 4G networks, wireless satellite networks), communication quality is easily affected by weather changes, signal strength, communication system resource occupancy, etc., and network fluctuations occur. The network fluctuations under the wireless network can be roughly divided into two types: one is that the network delay is high, and the other is that the network bandwidth fluctuates greatly. When transmitting audio and video in a wireless network environment, if there are network fluctuations, the video playback will not be smooth (stuck), the delay will become larger, and even the flow will be cut off.
[0028] To solve this problem, the embodiment of the present invention provides a method for high-quality wireless transmission of ultra-high-definition video, which is applied in the following two specific scenarios: (1) point-to-point live video broadcasting in a wireless network environment: the host...
Embodiment 2
[0064] figure 2 It is a schematic diagram of a system for high-quality wireless transmission of ultra-high-definition video provided according to an embodiment of the present invention, which is applied to a video wireless transmission system including an encoder and a decoder. Such as figure 2 As shown, it includes: a congestion control module 10 , a first acquisition module 20 , a first adjustment module 30 , a second acquisition module 40 , and a second adjustment module 50 .
[0065] Specifically, the congestion control module 10 is configured to use the FAST TCP congestion control algorithm to control the size of the sending window of the video to be transmitted from the encoder to the decoder.
[0066] The first acquiring module 20 is configured to acquire the transmission bandwidth corresponding to the sending window.
[0067] Specifically, the first acquisition module 20 first acquires the round-trip delay between the encoder and the decoder of the video to be tran...
