Title
(EN) SCREEN RECORDING METHOD AND SCREEN RECORDING SYSTEM
(FR) PROCÉDÉ D'ENREGISTREMENT D'ÉCRAN ET SYSTÈME D'ENREGISTREMENT D'ÉCRAN
(ZH) 一种录屏方法和录屏系统
Abstract
(EN) Disclosed is a screen recording method. The method is applied to a system that comprises a first electronic device and a second electronic device, wherein the first electronic device establishes a communication connection with the second electronic device, and the second electronic device provides target display content to the first electronic device so as to display same on the screen of the first electronic device. The method comprises: a first electronic device receiving a screen recording instruction, wherein the screen recording instruction is used for instructing the first electronic device to record target display content displayed on the screen of the first electronic device; the first electronic device sending, according to the screen recording instruction, a screen recording request for performing screen recording on the target display content to a second electronic device; the second electronic device receiving the screen recording request, and generating and sending, according to the target display content, a screen recording response corresponding to the screen recording request to the first electronic device; and the first electronic device receiving the screen recording response, and performing screen recording on the target display content according to the screen recording response, such that the disclosure of sensitive information in the target display content can be prevented. Further disclosed is a screen recording system.
(FR) Est divulgué un procédé d'enregistrement d'écran. Le procédé est appliqué à un système comprenant un premier dispositif électronique et un second dispositif électronique, le premier dispositif électronique établissant une connexion de communication avec le second dispositif électronique, et le second dispositif électronique fournissant un contenu d'affichage cible au premier dispositif électronique de façon à afficher ce dernier sur l'écran du premier dispositif électronique. Le procédé consiste : à recevoir, par un premier dispositif électronique, une instruction d'enregistrement d'écran, l'instruction d'enregistrement d'écran étant utilisée pour commander au premier dispositif électronique d'enregistrer un contenu d'affichage cible affiché sur l'écran du premier dispositif électronique ; à envoyer, par le premier dispositif électronique, en fonction de l'instruction d'enregistrement d'écran, une demande d'enregistrement d'écran afin d'effectuer un enregistrement d'écran sur le contenu d'affichage cible à un second dispositif électronique ; à recevoir, par le second dispositif électronique, la demande d'enregistrement d'écran, et à générer et à envoyer, en fonction du contenu d'affichage cible, une réponse d'enregistrement d'écran correspondant à la demande d'enregistrement d'écran au premier dispositif électronique ; et à recevoir, par le premier dispositif électronique, la réponse d'enregistrement d'écran, et à réaliser un enregistrement d'écran sur le contenu d'affichage cible en fonction de la réponse d'enregistrement d'écran, de telle sorte que la divulgation d'informations sensibles dans le contenu d'affichage cible puisse être empêchée. Est également divulgué un système d'enregistrement d'écran.
(ZH) 本申请公开了一种录屏方法,用于包括第一电子设备和第二电子设备的系统,其中第一电子设备和第二电子设备建立通信连接,并且第二电子设备向第一电子设备提供目标显示内容,以在第一电子设备的屏幕显示,该方法包括:第一电子设备接收录屏指令,录屏指令用于指示第一电子设备录制在第一电子设备的屏幕上显示的目标显示内容;第一电子设备根据录屏指令向第二电子设备发送对目标显示内容进行录屏的录屏请求;第二电子设备接收录屏请求,根据目标显示内容,生成并发送对应于录屏请求的录屏应答至第一电子设备;第一电子设备接收录屏应答,根据录屏应答对目标显示内容进行录屏,可以避免目标显示内容中敏感信息的泄露。本申请还公开了一种录屏系统。
