Digital content distribution system

本发明提供了一种产生将内容编码和被配置成一些消息的用密码保护的数字数据的方法，每个消息可由在一个具有一个服务接口的客户机上的解码器应用解码，由服务接口装配用于解码器应用的每个消息，这种方法包括下列步骤：从一个机器可读媒体检索一个消息；对所述消息的至少一部分进行加密；以及提供经加密的消息作为输出，其格式使一个服务器服务接口能将消息配置成至少一个包括至少一个头标和一个净荷的分组，每个净荷包括这个消息的至少一部分，至少一个头标包括使客户机上的服务接口能从这些分组的净荷装配用于解码器应用的每个消息的信息。这种方法包括将每个消息分成第一消息段和至少一个另外消息段。至少一个消息段加密成可独立于其他消息段解密。经加密的消息通过为至少所述另外消息段添加一个将一个消息段与一个相邻的消息段分开和包括显式同步信息的再同步标记予以装配。 A method comprising distributing digital data encoding content and arranged into messages from a server to one or more client terminals through a network, each message being decodable by a decoder application on a client terminal, said method including transmitting a plurality of data packets from the server through a network through a network interface of the server, each packet including at least one header and a payload, each payload including at least part of a message, and providing each message to a first of a series of at least one service interface between two layers in a protocol stack, installed on the server, each service interface configured to add at least one packet header to the packet encoding information enabling the client to process the remainder of the packet.
