摘要： A method for producing and for subsequently decrypting a protected stream of compressed video content is described herein. The method includes receiving an input stream of compressed video content containing a sequence of frames. A set of encrypted frames are created by encrypting selected frames of the sequence of frames in accordance with a frame encryption function. The method further includes generating frame decryption information necessary to decrypt the set of encrypted frames. In a particular implementation the protected stream is assembled using the set of encrypted frames, unencrypted frames from the input stream, and the frame decryption information. The decryption process is initiated by receiving the protected stream of compressed video content and the corresponding frame decryption information. In this regard the frame decryption information includes data distinguishing the encrypted frames from the unencrypted frames of the compressed video content within the protected stream. The encrypted frames are then decrypted in accordance with the frame decryption information.
摘要翻译：本文描述了用于产生和随后解密压缩视频内容的受保护流的方法。该方法包括接收包含帧序列的压缩视频内容的输入流。通过根据帧加密功能加密帧序列的选定帧来创建一组加密帧。该方法还包括生成解密该加密帧集所需的帧解密信息。在特定实现中，使用加密帧集合，来自输入流的未加密帧和帧解密信息来组合受保护流。通过接收压缩视频内容的受保护流和对应的帧解密信息来启动解密过程。在这方面，帧解密信息包括区分加密帧与受保护流内的压缩视频内容的未加密帧的数据。然后根据帧解密信息对加密的帧进行解密。

摘要： A file for storing digital data with high compression rate stores digital data for video and audio signals in multiple streams interleaved with each other. Each track has a stream descriptor list and a stream data list. The stream descriptor list includes a stream header chunk, a stream format chunk, and a stream name chunk. For a video stream, the stream descriptor list also includes a stream header data chunk if the video stream is under digital rights management (DRM) protection. The file format is compatible with high level data compressing algorithms, such as MPEG-4, which provide data compression ratio about six to ten times higher than a standard DVD format.

摘要： Described are methods, devices, and systems to provide enhanced wireless coverage for wireless mobile stations by facilitating centralized authentication for a variety of unrelated networks. The mobile stations can then access Internet and telephony resources via the various networks for improved coverage and bandwidth. Some embodiments support the extension of network coverage using wireless-access points that can be partitioned into multiple virtual access points, one associated with an enterprise and another with an overlay network that facilitates mobile communication over multiple networks. One physical access point can support an enterprise network using one virtual access point and the overlay network using another. Users unaffiliated with an enterprise can access the overlay network via the enterprise's physical access point without gaining access to the enterprise network.
