Embodiment 1

[0036] figure 1 A flow chart of a video-based communication method provided by an embodiment of the present invention, such as figure 1 As shown, the method is executed on the display device side, including:

[0037] Step 101: Obtain a video single-frame image list and select some single-frame images in the single-frame image list;

[0038] Specifically, the display device includes an electronic billboard composed of LED or LCD, an electronic product screen, etc., which is not limited in the present invention;

[0039] Specifically, the video is analyzed by a video analysis technology to obtain a single frame image list of a single frame image of the video. The video analysis technology is such as video editing software such as Avid media composer and Adobe Premiere, which is not limited by the present invention;

[0040] The embodiment of the present invention can determine the number of single-frame images to be used and the position of the single-frame images to be used i...

Embodiment 2

[0063] image 3 It is a schematic diagram of a method for obtaining a single-frame image list and selecting a part of a single-frame image provided by an embodiment of the present invention, as shown in image 3 As shown, the method includes:

[0064] Step 301: Obtain the first single-frame image list of the video;

[0065] Specifically, the embodiment of the present invention obtains a first single-frame image list including all single-frame images that make up the video by parsing the video;

[0066] In other embodiments, it is also possible to obtain a first single-frame image list including some single-frame images that make up the video, which is not limited in the present invention;

[0067] Step 302: Duplicate each single-frame image in the first single-frame image list to obtain a copy of each single-frame image;

[0068] Step 303: inserting copies of each single-frame image before or after each corresponding single-frame image in the first single-frame image list t...

Embodiment 3

[0094] Figure 5 A schematic diagram of a video-based communication method provided by an embodiment of the present invention, such as Figure 5 As shown, the method includes:

[0095] The original video consists of a set of frame images [A 1 ,A 2 …A N ], each frame of image A is obtained through video parsing i , and then according to the input information to be transmitted, through the image preprocessing process, the transmission information is embedded in the group of images at intervals, that is, only one of the two images before and after is embedded with information, and the other image is used as a reference frame. Therefore, a set of modulated frame images is obtained in Indicates the corresponding frame image A n Image after embedding (modulating) information;

[0096] Referring to the parameters of the original video, the adjusted frame images are synthesized into a video, and then sent out through the display device; the output of the display device is a ...

Abstract

The present invention provides a video-based communication method and apparatus and belongs to the communications technical field. According to the video-based communication method and apparatus of the invention, information to be transmitted is embedded in a part of single-frame images of a video through an image preprocessing mode, so that a target video in which the information to be transmitted is hidden is obtained, so that a user cannot see the information to be transmitted while watching the video. According to the method, by means of difference between a human eye channel and an imaging channel, the information to be transmitted is hidden in the target video, and therefore, the problem of poor user experience caused by a condition that the information to be transmitted is directlydisplayed with the playing of the video can be avoided; when the user is interested in video content, he or her can obtain the target video by using an imaging device; the information to be transmitted can be extracted through comparing the single-frame images of the target video with the information to be transmitted embedded in and the single-frame images with no information to be transmitted embedded in; the user can obtain the information to be transmitted through user equipment with an imaging function anytime and anywhere; and the propagation and diffusion of the information to be transmitted can be facilitated.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a video-based communication method and device. Background technique [0002] When watching video advertisements, users are often forced to watch relevant information such as merchant QR codes, order numbers, and purchase links displayed along with the video advertisements. These information often block the screen and affect the video display effect, which seriously reduces the viewing experience. [0003] Therefore, there is an urgent need for a communication method and device that does not affect the user's viewing experience and enables the user to obtain video-related information in a timely manner. Contents of the invention [0004] Embodiments of the present invention provide a video-based communication method and device, which avoids the problem of poor user experience caused by displaying information to be transmitted during video pla...
