Embodiment Construction

[0041] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail by citing the following embodiments and referring to the accompanying drawings.

[0042] During a video call, usually, the two parties in the call talk to the camera, the image captured by the camera does not change much, the video image seen by the two parties in the call is almost unchanged, and the transmitted video information has a lot of redundancy. Based on this In the video call method of the embodiment of the present invention, the video transmission is carried out uninterruptedly only when the frequency of the video captured by the camera changes rapidly. The present invention detects the video frames collected by the camera at regular intervals. When it is found that the change between two video frames is lower than the set threshold within a certain period of time, it is considered that the call video has n...

Abstract

The invention discloses a video call method, comprising: performing frame sampling on video data sent within a set period of time, and determining that the rate of change between the sampled video frames is less than or equal to a set threshold, no longer sending video data, The receiving end is notified to repeatedly play the video data in the previous set period. The invention also discloses a video call device and a mobile terminal. The technical scheme of the invention not only ensures good video call experience for users, but also greatly saves network resource occupation.

Description

technical field [0001] The present invention relates to video communication technology, in particular to a video call method and device, and a mobile terminal. Background technique [0002] With the rapid development of third-generation mobile communications, more and more mobile terminals provide video call services. However, since video calls have high requirements on network bandwidth, they occupy a large amount of mobile communication network resources. When many people use it at the same time, the network transmission data will be large, which will affect the transmission quality of the video call and cause a decline in user experience. [0003] At present, there are technologies that use certain methods to reduce the occupation of the network by video calls and ensure user experience. For example, in the prior art, when network congestion affects video data transmission, the user manually transmits still images to ensure the effect of video calls; Set still image. I...
