Video signal labeling method, system and device

Abstract

The present invention discloses a video signal labeling method, system and device. The method includes the steps of: receiving a video stream of an accessed signal source, converting the video stream into a first IP signal, and sending the first IP signal to A labeling operation terminal connected through a network, and receiving the labeling track sequence information returned by the labeling operation device, wherein the terminal generates the labeling track in response to a user's labeling operation when displaying an IP signal image based on the first IP signal Sequence information; read the first coordinate range and the local second coordinate range of the labeling operation terminal; draw the corresponding second coordinate range according to the first coordinate range, the second coordinate range, and the labeling track sequence information Annotated track image of the coordinate range; the marked track image is synthesized with the corresponding local IP signal image and then output, realizing the labeling of videos corresponding to various types of signal sources.

Description

technical field [0001] The present invention relates to the field of video technology, in particular to a video signal labeling method, system and device. Background technique [0002] Annotation is a method that people often use in daily life to facilitate others to understand and understand what they refer to or describe. In many applications of computers, annotation functions have also been added, such as Word, AutoCad, pdf readers and many other software have added annotation functions. In addition, with the development of video technology, video technology has been widely used in fields such as radio and television, film, video surveillance, and video conferencing. The object of people's discussion is no longer limited to documents and pictures, but videos. Therefore, video annotation is naturally needed by people. [0003] However, the existing video labeling can only be marked for the video corresponding to the PC signal source, that is to say, it can only be marked...

Problems solved by technology

[0003] However, the existing video labeling can only be marked for the video corresponding to the PC signal source, that is to say, it can only be marked for the video displayed in the application of the PC, and the types of signal sources are various. For example, it also includes various types of signal sources such as Video, VGA, HDMI, and ARGB / DRGB, so there is an urgent need for a way to mark videos corresponding to various types of signal sources
