Embodiment Construction

[0205] The terminology used in the embodiments of the present application is only used to explain the specific embodiments of the present application, not intended to limit the present application.

[0206] The transmission method of the video image provided herein can be applied to various types of real-time audio and video interactive scenes, for example, two users perform video calls by each electronic device, or multiple users via the electronic devices used. The telephone conference can be used in the transmission method of the video image proposed by the present application.

[0207] figure 1 For the two users, the electronic device of the respective electronic devices is used for video calls, as shown in FIG. The two users may be user A and user B, when the user A sends a video stream to the user B, the electronic user A used by the electronic The device can be the transmitted terminal A, and the electronic device used by the user B can be the receiving end B. The transmi...

Abstract

Embodiments of the invention provide a video image transmission method, video image sending equipment, a video call method and video call equipment. A video image comprises a plurality of video frames. The video image transmission method comprises the step of encoding the plurality of video frames to obtain an encoded code stream, wherein the code stream at least comprises information indicating an inter-frame reference relationship. In the video image transmission method, each of first N frames of a current frame refers to a forward LTR frame closest to a time domain of the current frame, andthe forward LTR frame is the encoded video frame marked as the LTR frame by the sending end equipment, that is, in the method, when the LTR frame is marked by the sending end equipment, feedback of receiving end equipment does not need to be waited for, so that marking of multiple LTR frames in one RTT can be realized, and therefore, the inter-frame reference distance can be greatly shortened, and the coding quality of video images is improved.

Description

Technical field [0001] The present application relates to the field of communication technologies, and in particular, to a transmission method, a transmission device, a video call method, and a device of a video image. Background technique [0002] With the further development of 5G, people's demand for video interaction is also more strong, and video calls act as interactive interactive infrastructure, in recent years, it has grown rapidly. Now, video calls have been embedded in the in-vehicle terminal, wisdom big screen, drone, children's watch, smart speaker, and remote medical, etc., to realize the future intelligent social full-time interconnection. [0003] Although the network coverage is increasing, and the real network situation is also complex, the weak signal coverage area, the home wireless network (WiReless Fidelity ;; WiFi) Wall and public WiFi multi-user strong occupation, etc. There is a phenomenon such as sudden high packet and / or network congestion, resulting ...
