Embodiment approach

[0039] According to an embodiment of the device of the present invention, the negotiation code rate and / or negotiation encoding format determination module 206 includes: a first code rate determination submodule, configured to, in response to the network parameter value being less than the first value, negotiate The code rate is determined as the first code rate; and the second code rate determining submodule is configured to determine the negotiated code rate as the second code rate in response to the network parameter value being greater than the second value. The first value is the difference between the set normal packet loss delay value and the preset step value, and the second value is the sum of the set normal packet loss delay value and the preset step value.

[0040] According to another embodiment of the device of the present invention, the detection module 202 uses a combination of ping and iperf technologies to detect network delay, packet loss rate and bandwidth. ...

Abstract

The application discloses a video communication method and device. The method comprises the steps of: detecting a network delay, a packet loss rate and a bandwidth of a transmitted video; determininga network parameter value of the transmitted video, wherein the network parameter value is a weighted array of at least two of the network delay, the packet loss rate and the bandwidth; according to the network parameter value, determining a negotiation code rate and / or a negotiation coding format; sending the determined negotiation code rate and / or negotiation coding format to an opposite end ofvideo communication; and receiving video data processed according to the negotiation code rate and / or the negotiation coding format from the opposite end. According to the method and device disclosedby the invention, the code rate and / or the coding format of video transmission can be regulated in real time according to a network condition so as to ensure quality of video communication.

Description

technical field [0001] The present application relates to the field of image communication, in particular to a video communication method and device. Background technique [0002] The current video call technology is based on WEBRTC (web real-time communication). WEBRTC itself includes network feedback and control. For the network environment, WEBRTC natively calls Google's REMB technology. This technology maintains a state machine at the receiving end according to the packet loss rate or data delay. , by increasing or decreasing the state value of the state machine, and then by sending RTCP (real-time control protocol) data packets to the peer end, to negotiate and adjust the code rate. However, WEBRTC does not implement peer processing natively. [0003] In a complex network environment, the network communication capability changes at any time. In order to ensure the quality of video communication as much as possible, it is necessary to adjust the video data in real time ...
