Embodiment Construction

[0021] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] Video service has become one of the most important applications of the current network. In the user's video service experience, the quality of picture and sound are the two biggest influencing factors. In the process of video production, sometimes due to technical failures of some equipment or systems, problems such as black frames, still frames, silence, and mosaics may occur. These problems will directly damage the video experience of users and affect the quality of video service providers. Brand. Therefore, before the video is uploaded to the server for broadcast, it needs to pass the quality review. Complete manual review will bring huge labor costs, and the review speed will easily become a bottleneck in the process of video online. Therefore, the way of machine-assisted manual work has gradually become a developm...

Abstract

The invention discloses a multi-mode parallel video quality fault detection device and a corresponding method. The device of the invention comprises a video partitioning module, a black field detection module, a static frame detection module, a mosaic detection module, a silence detection module, and a detection result merging module. Correspondingly, the method of the invention also comprises six steps, i.e., a video partitioning step, a black field detection step, a static frame detection step, a mosaic detection step, a silence detection step, and a detection result merging step. The technical scheme of the invention is adopted, through a framework of parallelization analysis, analysis work of video quality is divided to a plurality of CPUs to be carried out, and a corresponding system is realized, thereby greatly improving the speed of video quality examination.

Description

technical field [0001] The present invention relates to a video quality detection method and device, more specifically, to a multi-mode parallel video quality fault detection method and device. Background technique [0002] The video quality represents the brand image of the content service provider, so the video must pass the quality review before being uploaded to the server. Massive video review will bring huge labor costs, and it has become a development trend to use machines to assist manual review of video quality. However, with the continuous increase of video resolution, the computational complexity increases, and the traditional single-core computing mode is greatly limited. [0003] Serialized reading and computing make the speed of machine review limited by the computing power of a single CPU. Today, with the popularity of multi-core CPUs and multi-computing node clusters, traditional serialized quality inspection algorithms have been restricted by development. ...
