    • A method and a system for maintaining user privacy in a device (100) that continuously buffers video programming responsive to changes in a user selected video channel. Video programming can be continuously recorded on a storage medium (148) and presented on a display device. Recording can continue uninterrupted during and subsequent to a user change of the selected video channel. Responsive to a user input, at least a portion of the video programming that has been stored on the storage medium (148) can be deleted. The user input can be a single command input such as an actuation of a control key. The selected portion of the video programming that is deleted can be controlled by a pre-determined number of actuations of the control key. All of the video programming also can be deleted from the data storage medium. An interactive erase menu can provide menu selections for various erasing options.
    • 一种用于在设备(100)中维护用户隐私的方法和系统,其响应于用户选择的视频频道的改变而连续缓冲视频节目。 视频编程可以连续记录在存储介质(148)上并呈现在显示装置上。 在用户更改所选视频频道期间和之后,录制可以不间断地继续。 响应于用户输入,可以删除已经存储在存储介质(148)上的视频节目的至少一部分。 用户输入可以是单个命令输入,例如控制键的启动。 被删除的视频节目的所选择的部分可以通过预定数量的控制键的启动来控制。 所有的视频编程也可以从数据存储介质中删除。 交互式擦除菜单可以为各种擦除选项提供菜单选择。
