Title (EN) METHOD AND SYSTEM FOR LIMITING VIDEO PLAYING
(FR) PROCÉDÉ ET SYSTÈME DE LIMITATION DE LECTURE DE VIDÉO
(ZH) 一种视频播放的限制方法和系统
Abstract:
(EN) Disclosed are a method and system for limiting video playing. The method comprises: receiving a trigger instruction for clicking a video file; judging whether the video file is in a pre-set non-limited area; according to a judgement result, directly playing the video file if the video file is in the pre-set non-limited area; and outputting prompt information for decrypting the video file if the video file is not in the pre-set non-limited area, wherein pre-setting a non-limited area comprises dividing an area comprising at least one video file, and encrypting a video file outside the area. Therefore, the method and system for limiting video playing solve the problem that video file viewing cannot be limited for different viewing groups during media playing.
(FR) L’invention concerne un procédé et un système servant à limiter la lecture d'une vidéo. Le procédé consiste à : recevoir une instruction de déclenchement pour cliquer sur un fichier vidéo ; évaluer si le fichier vidéo se trouve dans une zone non limitée prédéfinie ; selon un résultat de l'évaluation, lire directement le fichier vidéo si le fichier vidéo est dans la zone non limitée prédéfinie ; et sortir des informations d'invite pour déchiffrer le fichier vidéo si le fichier vidéo n'est pas dans la zone non limitée prédéfinie, la prédéfinition d'une zone non limitée consistant à diviser une zone comprenant au moins un fichier vidéo et à chiffrer un fichier vidéo à l'extérieur de la zone. Par conséquent, le procédé et le système de limitation de la lecture d'une vidéo résolvent le problème selon lequel la visualisation du fichier vidéo ne peut pas être limitée pour différents groupes de visualisation durant une lecture multimédia.
(ZH) 一种视频播放的限制方法和系统,接收点击视频文件的触发指令;判断该视频文件是否在预先设置的非限制区域内;根据判断结果,若在预先设置的非限制区域内则直接播放该视频文件;若不在预先设置的非限制区域内则输出对该视频文件进行解密的提示信息;其中,所述预先设置非限制区域包括:划分包括有至少一个视频文件的区域,并对该区域外的视频文件加密。因此,所述视频播放的限制方法和系统解决了在媒体播放中不能针对不同的观看群体进行视频文件观看限制的问题。
