    摘要: A method, system, and computer program product for exercising rights based on determining trust in an issuance of a rights expression, including issuing rights expressions by a chain of servers, forming a chain of rights expressions issued from server to server and finally from the last server to a client, such that each of the rights expressions except the last includes a specification of rights for the next server to issue the rights in the next rights expression; determining whether or not each of the servers has a right to issue the respective rights expression; exercising by the client the rights expressed in the last rights expression as being trusted, if it is determined that each of the servers had a right to issue the respective rights expression; and not exercising by the client the rights expressed in the last rights expression as not being trusted, if it is determined that at least one of the servers did not have the right to issue the respective rights expression.

    摘要: An auxiliary device control for a subscriber terminal includes a four wire ribbon cable defining a bidirectional communication and data interface from the terminal to one or more auxiliary devices. A communication and data protocol for the bidirectional transfer of instructions, status, and data over the interface includes an address field, command or reply field, data length field, and checksum field transmitted at 9600 baud. In a preferred implementation, the auxiliary device to be controlled is an IR peripheral controller which can tune a VCR, and switch it on and off. Several transactions in the communications and data protocol are used to effect the operation where a control VCR command and reply transaction cause the control of the tuning and recording of the VCR. A set-up VCR command and a brand reply transaction is used to provide information to configure the controller with brands and model of the VCRs. A program event code command and a program event timer reply transaction provide for the automatic recording of a program event based on an event code listed in a television schedule. A channel map command and a reply transaction provide for the downloading of the local cable system channel line up into the controller.
