    • A system computes a combined dominant color descriptor (DCD) of a plurality of images (IM 1, IM 2, IM n). The system comprises an input 206 for receiving a plurality of respective dominant color descriptors (DCD 1, DCD 2, DCD n) of respective images of the plurality of images (IM 1, IM 2, IM n). The system further comprises means 202 for generating a collection of generated color values (IM) based on dominant colors included in the received dominant color descriptors (DCD 1, DCD 2, DCD n), and means 204 for computing at least one dominant color of the collection of generated color values (IM) for inclusion in the combined dominant color descriptor (DCD). In the collection, at least one generated color value is included representing a dominant color in one of the received dominant color descriptors.

    • 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。

    • Circuits (1) for navigating in a user- friendly way through video signals comprising shots and scenes shots are provided with shot boundary detectors (3) for detecting shot boundaries between shots and with scene boundary detectors (2) for detecting scene boundaries between scenes and with controllers (4) for controlling the boundary detectors (2,3) for said navigating. Scene control parts (42) control the scene boundary detectors (2) for finding one or more shots at the start or at the end of a particular scene and shot control parts (43) control the shot boundary detectors (3) for finding a particular shot. Direction control parts (44) control the scene control parts (42) for detecting scene boundaries in one of two opposite directions and control the shot control parts (43) for detecting shot boundaries in the other one of the two opposite directions. Output parts (71-73) of output interfaces (7) provide first images of first shots and second images of second shots for being displayed simultaneously. Selection control parts (45) select the first and second images.
    • 用于以用户友好的方式通过包括镜头和场景镜头的视频信号导航的电路(1)设置有用于检测镜头之间的镜头边界的镜头边界检测器(3)和用于检测场景与场景边界之间的场景边界的场景边界检测器(2) 控制器(4)用于控制用于所述导航的边界检测器(2,3)。 场景控制部分(42)控制场景边界检测器(2),用于在特定场景的开始或结束处发现一个或多个镜头,并且镜头控制部分(43)控制镜头边界检测器(3)以找到特定场景 射击。 方向控制部件(44)控制用于检测两个相反方向之一的场景边界的场景控制部分(42),并且控制用于检测两个相反方向中另一个中的拍摄边界的镜头控制部分(43)。 输出接口(7)的输出部分(71-73)提供第一次拍摄的第一图像和第二次拍摄的第二图像,以便同时显示。 选择控制部件(45)选择第一和第二图像。
