摘要： A system for sharing media content between peers over a communication medium. Content is authenticated prior to being downloaded, or stored, so that only content from designated peers, or based on other user selected criteria, reaches the user. Typically, content is stored at the destination site on a fixed or removable media prior to user content playback. Users are notified of content receipt, such as by an entry within a programming guide through which convenient user access of content may occur without the need to log onto the Internet or other service. The media content is then played back over a virtual channel that is selected by the user. The functionality of the system may be embodied within a separate unit or incorporated within set-top boxes, television sets, audio systems, gaming systems, personal computer system, or other interconnected electronic devices. Content may be communicated between peers on a device back-channel over a telephone system, Internet, cable network, powerline network, wireless connection, or direct wired link.
摘要翻译： 一种用于通过通信介质在对等体之间共享媒体内容的系统。 在下载或存储内容之前对内容进行认证，使得仅来自指定对等体的内容或基于其他用户选择的标准的内容到达用户。 通常，在用户内容播放之前，将内容存储在固定或可移动媒体上的目的地站点。 用户被收到内容收据的通知，例如编程指南中的条目，可以通过该条目方便用户访问内容，而无需登录Internet或其他服务。 然后，媒体内容通过用户选择的虚拟频道进行回放。 系统的功能可以体现在单独的单元内，或者被并入机顶盒，电视机，音频系统，游戏系统，个人计算机系统或其他互连的电子设备中。 可以通过电话系统，因特网，有线网络，电力线网络，无线连接或直接有线链路在设备背信道上的对等体之间传送内容。

摘要： Pan-scan is provided for a standard 4:3 aspect ratio TV displaying a 16:9 aspect ratio high definition (HD) video stream using the motion vectors that are part of MPEG-encoded streams. Specifically, if, for instance, the MPEG motion vectors indicate an object rapidly moving to the left, the left-most part of the HD video frames are shown, instead of remaining centered on the HD video frames and cutting off the left and right portions.
