Video and picture multi-resolution self-adaptive video watermarking method and system

Abstract

The invention relates to the technical field of streaming media processing, and particularly provides a video and picture multi-resolution self-adaptive video watermarking method and system. The method comprises the steps: adopting the Java high-level language to carry out multi-thread processing, employing a general processor CPU as a host end to run a main program, and distributing a video watermark task to a task execution module executor through a task distribution module dispatcher; enabling the executor to add each received transcoding task into a thread pool, wherein the thread pool allows 10 video watermarking tasks to be carried out at most at the same time; when one video watermarking task is finished, releasing the thread, wherein at the moment, the next video watermarking taskcan enter the thread pool to be processed. Compared with the prior art, the method completes the user-defined video watermark adding function, the video watermark adding success rate is increased, theapplication stability is guaranteed, and the method has good popularization value.

Description

technical field [0001] The invention relates to the technical field of streaming media processing, and specifically provides a video watermarking method and system for video and picture multi-resolution self-adaptation. Background technique [0002] Watermark refers to the addition of certain digital information in data multimedia (such as images, sounds, video signals, etc.) to achieve the functions of document authenticity identification and copyright protection. The embedded watermark information is hidden in the host file without affecting the observability and integrity of the original file. Therefore, there are many types of watermarks that can be added during the video encryption process, such as copyright owner LOGO, warning language at any location, text advertisements, and marquee watermarks, etc. Although various watermarks have different technical implementation forms during the video encryption process, their purposes are the same. It is to increase the difficu...

Therefore, there are many types of watermarks that can be added during the video encryption process, such as copyright owner LOGO, warning language at any location, text advertisements, and marquee watermarks, etc. Although various watermarks have different technical implementation forms during the video encryption process, their purposes are the same. It is to increase the difficulty of video cracking, increase the operating cost of pirates, and reduce the probability of video cracking

[0003] However, in the existing technology, the processing complexity of video information is very high, and the success rate of adding watermark is not very high, and the resolution of video and watermark pictures also has the problem of mismatching.
