Abstract

The invention provides a superposition method and an auxiliary information superposition device for auxiliary information of video signals. The method comprises the following steps of: acquiring an audio signal of a first meeting place and at least one video signal of the first meeting place, wherein the at least one video signal comprises a plurality of video objects of the first meeting place; acquiring indication information, wherein the indication information is used for indicating a video area where a video object is positioned corresponding to the acquired audio signal in the plurality of video objects of the at least one video signal; and performing superposition processing on text information corresponding to the audio signal of the first meeting place and the video signal according to the indication information so as to display the text information in the video area indicated by the indication information. The method guarantees that the audio signal can be displayed in a corresponding display screen where the video signal is positioned in a caption form under the video conference application scene with multiple images, so the consistency of display directions of the images and the captions is guaranteed.

Description

technical field [0001] The invention relates to the technical field of multi-screen video communication, in particular to a method and device for superimposing auxiliary information of video signals. Background technique [0002] Telepresence technology is a teleconferencing technology that has emerged in recent years and integrates video communication and communication experience. Because it has the characteristics of life-size, ultra-high-definition, low-latency, and pays attention to the effect of real face-to-face communication, it has With a strong sense of reality and presence, it has been widely used in various video conferencing scenarios. [0003] The telepresence conference system pays attention to the consistency of the sound orientation and image, so it can well meet the needs of the participants for the image and sound, but the existing telepresence technology still has certain deficiencies: in a telepresence conference, many There may be participants who speak...
