    • A system and process for highlighting the current speaker on an on-going basis in each frame of a low frame-rate video of an event having multiple people in attendance is presented. In general, this is accomplished by periodically identifying an attendee that is currently speaking at a rate substantially faster than the video frame rate, and updating each frame of the video to highlight the current speaker. More particularly, an A/V source provides a video stream to a client computing device that includes delta frames interspersed between the frames of the low frame-rate video. The full video frames act as keyframes, and the delta frames provide the changes needed to modify the last displayed version of the last keyframe to highlight just the region associated with the location of a current speaker. This allows the client device to operate as a standard A/V rendering and display unit.
    • 提出了一种系统和过程,用于在具有多个出席者的事件的低帧率视频的每帧中持续突出显示当前扬声器。 一般来说,这通过周期性地识别当前以比视频帧速率更快的速率来表示的参加者,并且更新视频的每个帧以突出显示当前的说话者来实现。 更具体地,A / V源向客户端计算设备提供视频流,该客户端计算设备包括分散在低帧率视频帧之间的增量帧。 完整的视频帧作为关键帧,增量帧提供修改最后一个关键帧的最后显示版本所需的更改,以突出显示与当前扬声器位置相关联的区域。 这允许客户端设备作为标准的A / V渲染和显示单元运行。

    • Concepts and technologies are described herein for cache management. In accordance with the concepts and technologies disclosed herein, the server computer can be configured to communicate with a client device configured to execute a cache module to maintain a cache storing data downloaded from and/or uploaded to the server computer by the client device. The server computer can be configured to receive requests for data stored at the server computer. The server computer can be configured to respond to the request with hashes that correspond to the requested data. The client device can search the cache for the hashes, obtain the data from the cache if the hashes are found, and/or download the data from the server computer if the hashes are not found. The client device also can be configured to update the cache upon uploading the data to the server computer.
    • 这里描述了用于高速缓存管理的概念和技术。 根据本文公开的概念和技术,服务器计算机可以被配置为与被配置为执行高速缓存模块的客户端设备通信,以维护存储由客户端设备从服务器计算机下载和/或上传到服务器计算机的数据的高速缓存。 可以将服务器计算机配置为接收存储在服务器计算机上的数据的请求。 可以将服务器计算机配置为使用与所请求数据相对应的散列来响应请求。 客户端设备可以在高速缓存中搜索散列,如果发现散列,则从缓存获取数据,如果没有找到散列,则从服务器计算机下载数据。 客户端设备还可以配置为在将数据上传到服务器计算机时更新缓存。

    • Encrypted content is synchronized without requiring a password. The structure of the data is synchronized while the content of the data remains encrypted. When the user desires viewing the encrypted content of the structure, the user is prompted for the password to render the encrypted content. Succinctly stated, the password requirement is pushed from the time of synchronization to the time of rendering of the content. In this manner, a user may synchronize a device without needing to enter a password. Such keyless synchronization promotes efficiency, increases productivity and pushes the password prompt to a more optimal time for the user.
    • 加密内容是同步的,不需要密码。 当数据的内容保持加密时,数据的结构被同步。 当用户期望查看结构的加密内容时,提示用户输入密码以呈现加密的内容。 确切地说,密码要求从同步时间推送到内容呈现时。 以这种方式,用户可以同步设备而不需要输入密码。 这种无钥匙同步促进效率,提高生产力并将密码提示推送给用户更佳的时间。
