摘要： A content preview of a content item is generated by extracting one or more clips from the content item, each clip is identified using a clipping point, a clip duration, a starting point, which is identified using the clipping point, and an ending point, which is identified using the clip's starting point and clipping duration. By way of a non-limiting example, shot boundaries are identified within the content item, the clip's starting point is identified to be the shot boundary before and closest to the clip's clipping point, the clip's ending point is identified to be the shot boundary after and closest to the clip's starting point plus clip duration. In a case that multiple clips are generated for the content preview, the clips are multiplexed to form the content preview. In a case that the content item comprises different types of content, such as audio and video content, the audio and video content is extracted from the content item for each clip, and synchronized to form the clip.
摘要翻译：通过从内容项中提取一个或多个剪辑来生成内容项的内容预览，使用剪切点，剪辑持续时间，使用剪切点识别的起始点和结束点来标识每个剪辑，使用剪辑的起始点和剪辑持续时间来标识。作为非限制性示例，在内容项目中识别拍摄边界，将剪辑的起始点识别为在剪辑剪辑点之前和最接近剪辑剪辑点的拍摄边界，剪辑的终点被识别为拍摄边界后并且最接近剪辑的起点加剪辑持续时间。在为内容预览生成多个剪辑的情况下，剪辑被多路复用以形成内容预览。在内容项目包括诸如音频和视频内容的不同类型的内容的情况下，从每个剪辑的内容项目中提取音频和视频内容，并且被同步以形成剪辑。

摘要： Techniques are described to encode video content for mobile devices. A video content that is to be transmitted to a mobile device is received and different scenes are determined for the video content. For each scene that is found in the video content, one or more analysis techniques are performed on the scene. Based upon the results of the analysis techniques, the portion of the image to retain on each scene is determined. Finally, the video content containing the portion of the image on each scene to be retained is encoded based upon the type of the mobile device that will display the video content. The location and dimensions of each portion to be retained may vary from scene to scene, as these characteristics are determined on a per-scene basis.
摘要翻译：描述技术来编码用于移动设备的视频内容。接收要发送到移动设备的视频内容，并为视频内容确定不同的场景。对于在视频内容中找到的每个场景，在场景上执行一个或多个分析技术。基于分析技术的结果，确定保留在每个场景上的图像部分。最后，根据将显示视频内容的移动设备的类型，对包含要保留的每个场景上的图像部分的视频内容进行编码。每个要保留的部分的位置和尺寸可能因场景而异，因为这些特征是在每个场景的基础上确定的。
