    • An internet client-server method to rapidly preview video files. Source video files are compressed into lower resolution preview video files, thumbnail image files, and stored on a preview internet server. Typically only a small fraction of the source video frames, such as 1 frame in 60, is used for the preview. A user using a touch sensitive computerized device such as a smartphone can view the thumbnail video images while the compressed video files load in the background. When the user touches or swipes an image of interest, or shakes the device, device video preview application software detects the action and directs the device to start playing the preview video file(s). The application software detects when the user swipes the preview video, and changes the rate and direction of playback of the preview video file, and trickplay functionality, often according to the speed and/or direction of the swipe.
    • 一种用于快速预览视频文件的互联网客户端 - 服务器方法。 源视频文件被压缩成较低分辨率的预览视频文件,缩略图文件,并存储在预览互联网服务器上。 通常只有一小部分源视频帧,例如60帧中的1帧,用于预览。 使用触摸敏感的计算机化设备(例如智能手机)的用户可以在压缩的视频文件在后台加载的同时观看缩略图视频图像。 当用户触摸或滑动感兴趣的图像或摇动设备时,设备视频预览应用软件检测动作并引导设备开始播放预览视频文件。 应用软件检测用户什么时候滑动预览视频,并且经常根据滑动的速度和/或方向来改变预览视频文件的播放速率和方向以及特技播放功能。
