摘要： A system for providing persistent access control of protected content is disclosed. The method on a client system includes sending a first request for authentication of the client to a server system. Subsequently, the client is authenticated by the server. Next, a user on the client attempts to access a file comprising a trailer and content encrypted with an encrypting key. Then, a second request for access to the content is sent to the server by the client, wherein an identifier from the trailer is included in the second request. The identifier identifies the content or an access control policy of the content. The server determines that the second request is in accordance with an access control policy associated with the content, and grants access to the content. Lastly, the client accesses the content in accordance with the access control policy.

摘要： A method to delivery encrypted digital content to a end user system for playing the content comprising the steps of: reading from a computer readable medium metadata which has previously associated with the content. A user selects from the metadata associated content to decrypt and the end user system establishes a secure connection with an authorization authority for decrypting the content. The end user system receives a secure container containing the decrypting key for decrypting at least part of the previously encrypted content as permitted. The system creates a secure container using the encrypting key from a clearing house, wherein the secure container has an encrypting key therein from the end user system; transferring the secure container to the clearing house for authentication of permission to decrypt the content. The system receives from the clearing house, a secure container encrypted using the encrypting key of the end user system containing the decrypting key for decrypting at least part of the previously encrypted content stored on the computer readable medium as permitted; and playing at least part of the previously encrypted content by decrypting the secure container using the encrypting key of the end user system to access the decrypting key for decrypting at least part of the encrypted content.

摘要： A method of managing content data and associated metadata. According to the method, the content data and the associated metadata are generated. The content data is transferred to a content host, and the metadata and usage condition data for the associated content are transferred to an electronic store. The metadata and/or the usage condition data are altered in order to form promotional data, and the promotional data is transferred from the electronic store to a customer's system. In one preferred method, the content data is encrypted with a first encrypting key before being transferred to the content host. The first encrypting key is encrypted with a second encrypting key, and the encrypted first encrypting key is transferred along with the metadata and usage condition data to the electronic store. Additionally, the encrypted first encrypting key is transferred along with the promotional data to the customer's system.

摘要： In a data communication network wherein broadcasted transmissions include a portion uniquely identifying the content of the following transmission and wherein transmissions are repeated at predetermined intervals, a communication unit for operating within the system includes a receiver, a processor, and memory for storing data and instructions for the processor. The receiver receives transmissions over the communication network. The communication unit receives a record command from a user that causes it to record the audio/video content being broadcasted during a subsequent transmission thereof. The memory includes space for storing the program that causes the communication unit to automatically record the transmission at the time the transmission is re-broadcasted.

摘要： A serial simplex switch design is provided which includes I/O ports each of which is configurable specifically for attachment to a data communications subsystem or, alternatively, for cascaded connection to a similarly configured I/O port on another switch. The switch provides a packet routing function including input and output buffers for each of its I/O ports wherein packets of control messages sent by one subsystem are temporarily stored prior to being delivered to the appropriate destination subsystem. When configured to be directly attached to a subsystem, the I/O ports separate control messages from incoming integrated data and control message strings. In a cascade configuration, however, a mechanism is provided wherein data and control messages are separated into two physical paths to eliminate the delays associated with integrated data and control message flow through the cascaded I/O port. Each I/O port is configurable to either of these methods of operation by means of programmable latches associated with the I/O port.
摘要翻译：提供了一种串行单工开关设计，其包括I / O端口，每个I / O端口可专门配置用于连接到数据通信子系统，或者替代地，用于与另一开关上类似配置的I / O端口的级联连接。交换机提供分组路由功能，其包括其I / O端口中的每一个的输入和输出缓冲器，其中由一个子系统发送的控制消息的分组在被传送到适当的目的地子系统之前临时存储。当配置为直接连接到子系统时，I / O端口将控制消息与传入的集成数据和控制消息字符串分开。然而，在级联配置中，提供了一种机制，其中数据和控制消息被分成两个物理路径，以消除与集成数据相关联的延迟和通过级联I / O端口的控制消息流。通过与I / O端口相关联的可编程锁存器，每个I / O端口可配置为这些操作方法之一。
