    摘要: A method of traffic regulation in a packet communication network involves a token bucket associated with a subscriber. Packets arriving at the regulator are handled in accordance with the token bucket configuration. The method further involves measuring a demand placed on the packet communication network by the subscriber. The token bucket configuration for the subscriber is dynamically adjusted based on the demand. Another method of traffic regulation handles packets that arrive at the regulator in accordance with first and second token bucket configurations. The first token bucket regulates packet rate while the second token bucket regulates data rate. Another method of traffic regulation involves handling packets in accordance with a token bucket configuration, where the amount of tokens to be removed is based on the amount of the flow and is further based on a classification of the flow. Packet-level devices for traffic regulation are also contemplated.

    摘要: A technique is provided for securely transferring programming content from a first device in a first layer, e.g., a trusted domain, to a second device in a second layer, e.g., outside the trusted domain. When a user requests that the first device transfer protected content to the second device, the first device needs to authenticate the second device. After the second device is authenticated, the first device may transfer to the second device the protected content, together with a rights file associated therewith. The rights file specifies the rights of the second device to use the protected content, according to its security level indicative of its security. These rights may concern, e.g., the number of times that the second device may subsequently transfer the protected content to other devices, the time period within which the second device may play the protected content, etc.; The higher the security level of the second device is, the more rights accorded thereto. Indeed, the second device may need to meet a minimum security level requirement in order for it to receive or keep the protected content.

    摘要: A system and method for controlling the transmission of signals within an interactive network which transmits audio/visual (A/V) information on at least one channel to a user and including a transmission source configured to transmit the A/V information on the at least one channel is provided. The system includes at least one set-top box and at least one random number generator. The set-top box is configured to record the A/V information on a channel at a predetermined recording time and to transmit a change channel request signal to the transmission source prior to the predetermined recording time to change the channel to record the A/V information at the predetermined recording time. The random number generator is configured to generate a time value such that the at least one set-top box transmits the change channel request signal to the transmission source at the time value prior to the predetermined recording time.
