摘要： A content sharing method performed in a content redistribution device based on a non-realtime IPTV service includes transmitting a secret key in password information of a user of the content redistribution device to an IPTV service server and storing a public key corresponding to the secret key; and transmitting an event message for content request to the IPTV service server to request a non-realtime IPTV service. Further, the content sharing method includes receiving contents requested in the event message for content requesting from the IPTV service server; and decoding the received contents and encrypting the decoded contents using the public key. Furthermore, the content sharing method includes transmitting the contents encrypted using the public key to content recipient devices; and generating an event message for content sharing using the public key to transmit the generated event message to the content recipient devices.

摘要： An adaptive security policy based scalable video service apparatus includes a video streaming server, an adaptive security policy server and a terminal. The video streaming server receives a service demand via a network and generates an encrypted streaming data. The adaptive security policy server analyzes a media structure and the service demand, by using a service profile received from the video streaming server, so as to generate a security policy description. The terminal generates and transmits the service demand to the video streaming server or the adaptive security server, obtains the encrypted streaming data from the video streaming server and decrypts the encrypted streaming data for playback, storing and retransmission.
摘要翻译：一种基于自适应安全策略的可伸缩视频服务设备包括视频流服务器，自适应安全策略服务器和终端。视频流服务器通过网络接收服务需求并生成加密的流数据。自适应安全策略服务器通过使用从视频流服务器接收的服务简档来分析媒体结构和服务需求，以便生成安全策略描述。终端生成并发送业务需求给视频流服务器或自适应安全服务器，从视频流服务器获取加密的流数据，解密加密流数据进行重放，存储和重传。
