    • A moving picture coding/decoding apparatus capable of rapidly finding out a content of recorded moving picture data without completely decoding this moving-picture data content is constructed of an image coding/decoding unit (12) for coding/decoding a picture signal containing moving-picture information, a storage control unit (15), and a storage unit (16). In a small image generating unit (13), reduced resolution image signal (namely, "small image data") for indexing the original image signal is generated by sampling the image signal, or cutting out a portion of an image formed by the picture signal. This small image data is stored via the storage control unit (15) into the storage unit (16), while this small image data is correlated with the decoded image data obtained from the image coding/decoding unit (12). A selection is made of any one of the small image data read from the storage unit (16) and the restored image data derived from the image coding/decoding unit (12). Then, the selected image is displayed.

    • Cyclical pixel-based remapping techniques are disclosed for efficiently creating and displaying a video summary. Cyclical temporal remapping at the pixel level requires less processing power and eliminates the need for object identification and tracking, allowing for dynamic adjustment of summary video parameters while a user is viewing the summary video. An operator can select an archived camera feeds or video file, specify a time compression ratio or time interval over which to review video content, specify a motion sensitivity threshold, and then view a significantly condensed summary video that depicts all activity from the source video within a much shorter timeline. Furthermore, activity co-occurrence is preserved such that any activities that co-occur in the source video will also co-occur in the summary video.
    • 公开了基于周期性像素的重新映射技术,用于有效地创建和显示视频摘要。 像素级的周期性时间重新映射需要较少的处理能力,并且不需要对象识别和跟踪,允许在用户查看摘要视频时动态调整摘要视频参数。 操作员可以选择已存档的摄像机馈送或视频文件,指定时间压缩比率或查看视频内容的时间间隔,指定运动灵敏度阈值,然后查看描述来自源视频的所有活动的显着压缩的摘要视频 一个更短的时间表。 此外,活动共现被保留,使得在源视频中同时出现的任何活动也将在摘要视频中共同出现。

    • A video identifier uniquely identifying a video captured by a camera is generated. The video includes video frames and optionally concurrently captured audio as well as video metadata describing the video. Video data is extracted from at least two of the video's frames. By combining the extracted video data in an order specified by an identifier generation protocol, an extracted data object is generated. The extracted data object is hashed to generate the unique media identifier, which is stored in association with the video. The identifier generation protocol may indicate the portions of the video data to extract, such as video data corresponding to particular video frames and audio data corresponding to particular audio samples. The extracted data object may include a size of particular video frames, a number of audio samples in the video, or the duration of the video, for example.
    • 生成唯一地识别由相机拍摄的视频的视频标识符。 视频包括视频帧和可选地同时捕获的音频以及描述视频的视频元数据。 从视频的至少两个帧中提取视频数据。 通过以由标识符生成协议指定的顺序组合提取的视频数据,生成提取的数据对象。 所提取的数据对象被散列以生成与视频相关联地存储的唯一媒体标识符。 标识符生成协议可以指示要提取的视频数据的部分,例如对应于特定视频帧的视频数据和对应于特定音频样本的音频数据。 所提取的数据对象可以包括例如特定视频帧的大小,视频中的多个音频样本,或视频的持续时间。
