Abstract

The invention discloses a multiparty video data fusion realization method, a multiparty video data fusion realization device, a multiparty video data fusion realization system and a fusion server. The objective of the invention is to realize multiparty video data fusion at a server end so as to decrease bandwidth required by the fusion server to transmit video data to terminals and decrease processing resource and electric quantity consumption for the terminals in video data processing. The multiparty video data fusion realization method includes the following steps that: video image data transmitted by each user terminal which participates in multiparty video communication are received; each frame of video image data is drawn in any one of video image data drawing regions contained in pre-defined memory maps; and memory maps corresponding to video display region information are transmitted to corresponding user terminals respectively according to the video display region information of each user terminal, wherein the video display region information is used for indicating video image data to be displayed by the user terminals.

Description

technical field [0001] The present invention relates to the technical field of video data processing, in particular to a method, device, system and screen mixing server for realizing multi-party video data mixing. Background technique [0002] With the rapid development of the mobile Internet, providing a multi-party video call service on a mobile terminal has become one of the hotspot services of the mobile Internet. Existing multi-party video call services implemented on mobile terminals all adopt the traditional method of splitting video and mixing screens, that is, the server on the network side distributes the video data of each user in the multi-party video call to each user of the current call respectively , and then the terminal device completes the screen mixing operation by itself. Take three-party video calls as an example, such as figure 1 As shown, it is the existing video data processing method on the network side. The video server on the network side receive...
