Abstract
(EN) Provided are a screen-projection data processing method and a display device. After receiving screen-projection data sent by a mobile terminal, a display device extracts valid data from the screen-projection data, and uses the valid data to determine whether a picture needing screen projection is a landscape picture or a portrait picture. Thereafter, when a screen-projection picture is a portrait picture, the display device which is currently in a landscape state is rotated into a portrait state, invalid data in the projection-screen data is also cropped out, and only a picture corresponding to the valid data is displayed. Or, when the screen-projection picture is the portrait picture, if the display device is currently in the portrait state, the display device can directly crop out the invalid data from the projection-screen data, and can only display the picture corresponding to the valid data.
(FR) L'invention concerne un procédé de traitement de données de projection d'écran et un dispositif d'affichage. Après réception de données de projection d'écran envoyées par un terminal mobile, un dispositif d'affichage extrait des données valides à partir des données de projection d'écran, et utilise les données valides pour déterminer si une image nécessitant une projection d'écran est une image de paysage ou une image de portrait. Ensuite, lorsqu'une image de projection d'écran est une image de portrait, le dispositif d'affichage qui est actuellement dans un état paysage est mis en rotation de façon à le mettre dans un état portrait, des données invalides dans les données d'écran de projection sont également rognées, et seule une image correspondant aux données valides est affichée. Ou, lorsque l'image de projection d'écran est l'image de portrait, si le dispositif d'affichage est actuellement dans l'état portrait, le dispositif d'affichage peut directement recadrer les données non valides à partir des données d'écran de projection, et peut uniquement afficher l'image correspondant aux données valides.
(ZH) 本申请提供了一种投屏数据的处理方法及显示设备。当接收到移动终端发送的投屏数据后，显示设备会将投屏数据中的有效数据提取出来，并利用该有效数据确定需要投屏的画面是横屏画面还是竖屏画面。而后，显示设备在投屏画面为竖屏画面的情况下，将当前处于横屏状态的显示设备旋转为竖屏状态，同时将投屏数据中的无效数据裁切，只显示有效数据对应的画面。或者，在投屏画面为竖屏画面的情况下，如果显示设备当前处于竖屏状态，那么显示设备则可以直接将投屏数据中的无效数据裁切，只显示有效数据对应的画面。
