摘要： A contents provider stores contents data in a container in a format which can only be decoded with a key distributed from an EMD service center, and transmits the container to a service provider. The service provider adds pricing information and the like and distributes this to a user home network. The user home network pays charges to the EMD service center based on the pricing information, receives the key, and decodes the contents data. Information regarding the number of times which copying is permitted is contained in the secure container, and the number of times permitted is increased each time charges are paid, thereby enabling copying to other media and the like. It is impossible to make copies from a container simply copied, or in cases where in the number of permitted times of copies has been used up. Thus, contents data can be distributed in a format wherein copying of contents data can be controlled including the number of copies made.

摘要翻译： 内容提供者以只能从EMD服务中心分发的密钥解码的格式将内容数据存储在容器中，并将该容器发送给服务提供商。 服务提供商添加定价信息等，并将其分发给用户家庭网络。 用户家庭网络根据定价信息向EMD服务中心支付费用，接收密钥，并对内容数据进行解码。 关于允许复印的次数的信息被包含在安全容器中，并且每次支付费用都增加允许的次数，从而能够复制到其他介质等。 不可能从简单复制的容器中拷贝副本，或者在允许的复印次数已用完的情况下。 因此，内容数据可以以可以控制内容数据的复制的格式来分发，包括制作的份数。
