    摘要: A system, apparatus, and method are directed towards managing entitlement/right revocation and delivery to be performed within a non-addressable media network. Such networks may include for example a client device behind a network address translation (NAT) device, employs non-addressable satellite components, or so forth. A server notifies clients that entitlements, revocations, or the like are available by sending a request for communications with the client. The client initiates a connection to receive the entitlements, or the like, and then disconnects from the server. If the client fails to initiate a connection, the server may continue to send a request for a connection, or even change encryption keys to the content to prevent access by the client. In one embodiment, failure to receive an acknowledgement response from the server of a connection with the client, or from the client, may result in invocation of a revocation failure action.

    摘要: A software analysis system having a filter for selectively collecting tags generated by a target system during execution of a software program under analysis in accordance to a programmable filtering criteria. The system includes a decoder for decoding the tag type of the tags captured from the data bus of the target system, and a comparator for comparing the tag types to the programmable filtering criteria to determine whether the tag should be collected. The programmable filtering criteria may be programmed by collecting filter tags from the target system, or directly programmed by a software developer using a filtering user interface. The programmable filtering criteria is implemented by a filter table that stores a flag associated with each tag type. The flag is indicative of whether tag data of a respective tag type should be collected. Tag data of the tag types meeting the programmable filtering criteria have timestamp information appended to the tag data and are collected in a tag buffer.

    摘要: A system, apparatus, and method are directed to providing digital copy protection of media using a subscriber/publisher architecture. In one embodiment, a publisher employs various dynamic and/or static tamper detection, including, filter graph change detectors, ICE detectors, screen scraping detectors, debugger detectors, pattern recognizers, or the like. When a tampering event is detected by one or more of the publishers, the tamper event may be published for access by a subscriber. Published tamper events may be pushed to or pulled by the subscribers. When one or more subscribers receive the tamper event, the subscriber(s) may perform one or more tamper response actions according to various business rules, and/or other core rules.
