    • A device and a method for playing audio-video content (205) during which loss of attention of a user (192) is detected. Loss of attention of the user generates at least one attention loss marker (255) that is stored in an attention loss storage unit (210). The user may revert playback to a point in time corresponding to the attention loss marker using a user interface unit (190). By storing markers corresponding to points of attention loss by the user and requiring explicit user input, the attention loss detector may detect attention loss with an accuracy lower than would otherwise be the case. Optionally, storing of the attention loss markers may be made conditional upon a content analysis unit (420), such as a commercial block detector. An attention loss marker indication (260) may be made visible to the user to indicate that at least one attention loss marker has been detected.
    • 一种用于播放音频 - 视频内容(205)的装置和方法,在此期间检测到用户(192)的注意力的丧失。 用户的注意丧失产生存储在注意力丢失存储单元(210)中的至少一个注意力丢失标记(255)。 用户可以使用用户界面单元(190)将播放恢复到与注意丢失标记相对应的时间点。 通过存储与用户的注意力损失点相对应的标记,并且需要明确的用户输入,注意力损失检测器可以以比否则为更低的精度来检测注意力损失。 任选地,注意丢失标记的存储可以根据诸如商业块检测器的内容分析单元(420)进行。 注意丢失标记指示(260)可以使用户可见,以指示已经检测到至少一个注意力损失标记。
