Problems solved by technology

When the buffer is insufficient or the waiting time is over, the video data packets that cannot form a frame will be discarded
The more packets discarded, the more traffic and bandwidth will be wasted, and the worse the network environment, the easier it is to cause this waste
Some of them use caching to avoid the limitation of data due to insufficient bandwidth, but it also causes insufficient real-time video performance and the loss of some video time periods.

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0017] like figure 1 As shown, the video transmission method of the present invention includes:

[0018] S1, the transmitter and the receiver establish a transmission channel;

[0019] S2, the sender sends the video frame to the receiver at the initial frame rate;

[0020] S3, the receiver plays the video frame, and feeds back the rate of the video frame to the transmitter;

[0021] S4. The transmitter adjusts the transmission frame rate according to the feedback information, and continues to send video frames to the receiver at the adjusted frame rate.

[0022] During the continuous transmission process, the above steps are repeated, and the transmitter immediately adjusts the...

Abstract

The invention discloses a video transmission method and system. The video transmission method comprises the steps of establishing a transmission channel between a transmitter and a receiver; transmitting video frames to the receiver at an initial frame rate by the transmitter; playing the video frames and feeding back the rate of the video frames to the transmitter by the receiver; and adjusting the transmission frame rate based on the feedback information and carrying on transmitting the video frames to the receiver at the adjusted frame rate by the transmitter. Through real-time feedback of the video frame rate in the transmission process, and real-time judgment and adjustment for the transmission frame rate, the discarding problem of data packets in the video transmission is greatly reduced, and video transmission via a small data volume can be realized.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a video transmission method and system. Background technique [0002] At present, in most video transmission technologies, both the sender and the receiver can obtain high-definition and smooth video viewing experience when the network environment is good. However, when the bandwidth is limited in the 3G / 4G network environment, there will be problems such as slow video connection, long cache loading time, high traffic consumption, and bandwidth occupation. The reason for the existing technology is that the video is set to a fixed frame rate in video transmission. Under the condition of certain frame rate, resolution and video compression technology, the video data size is certain. When the bandwidth is not enough to complete the transmission of all video packets , most packets will be discarded after a part of the transmission. Not only does it cause slow drawing...
