    Abstract: A method and apparatus for the automatic access control to multimedia presentations at the receiver in accordance with a viewer selected access mode and access classification data encoded into the multimedia presentation. Screening classification codes (SCCs) are embedded in the Audio Visual Material (AVM) delivered to a subscribers home station. The screening classification codes identify the type of content that follows in the AVM stream. For instance, violent content (video and/or audio) provided to a home station may contain a SCC that indicates violent scenes or violent action is forth coming in the AVM stream. The home station takes the SCC that are encoded and/or embedded in the AVM stream and applies a subscriber selected screening criteria. The screening criteria or suppression criteria are AVM manipulation commands. These AVM manipulation commands can blank the audio and/or video, cause the display of the last acceptable frame, perform obscuration transforms on the AVM stream or otherwise manipulate the audio and/or video portions of the AVM stream. The subscriber associates an AVM manipulation command with each of the available SCCs. The home station applies the subscriber desired manipulation commands to the AVM stream. Information on the subscriber selections are provided to an upstream node for subscriber behavior collection analysis.

    Abstract: The disclosed embodiments filter out many unnecessary interrogations of the cache directories of processors in a multiprocessor (MP) system, thereby reducing the required size of the buffer invalidation address stack (BIAS) with each associated processor, and increasing the efficiency of each processor by allowing it to access its cache during the machine cycles which in prior MP's had been required for invalidation interrogation. Invalidation interrogation of each remote processor cache directory may be done when each channel or processor generates a store request to a shared main storage.

    Abstract: The architecture provides a frame format and procedure for routing messages through a single ring or multi-ring communication system. Stations associated with the exchange of messages are located on the single ring or on different rings of the multi-ring communication system. The rings are connected by bridges to form a physical local area network. The frame format includes a plurality of control bits positioned within a Routing Information (RI) field, a frame control field and a frame status field. Messages are generated and structured in accordance with the frame format. A group of the control bits, in each message, is set with initial values according to the message type. Thus, different messages are characterized by a different sequence of control bit settings. A routing algorithm analyzes the message and depending on the status of the control bits, the message is processed and ultimately switched to its proper destination.
