摘要： In a network Ring Op/Claim oscillations due to duplicate addresses and transmit aborts are avoided by using token preserver frames to reset the TVX timer in a station. The stations are capable of detecting transmissions on the network and of taking predetermined actions in the absence of detecting transmissions for a predetermined first time interval. There is further provided a timing means for measuring a second predetermined time interval and means for transmitting a reset frame onto the network by a selected station, the reset frames being transmitted at intervals substantially equal to the second predetermined time interval, causing a station to reset the first timer to a beginning value, the reset means capable of transmitting the reset frames between frames transmitted by the originating means.

摘要： A purging station selected for removal of no-owner frames in a token ring network, and a corresponding method for its operation. The purging station initiates a purge cycle only if the network is no 'idle' and, optionally, only if the network is not 'near fully loaded', these terms being defined in relation to a token cycle. Therefore, no unnecessary purge marker frames are transmitted onto the network when it is idle or near fully loaded. Once purging is initiated, the purging station transmits at least one purge marker frame onto the ring network, and strips data received from the ring until a purge termination flag is set, upon detection of a received purge marker frame, a received token, or detection of a ring re-initialization procedure.

摘要： In a distributed interactive multimedia service system, a client application (11) of a set-top box located at a customer premises generates an attach request (410) . A session manager (205), in response to receiving the attach request via a network, generates an allocation request (440) and a create request (450). A resource manager (210), in response to the allocation request, allocates resources of a plurality of multimedia servers. The resources can include processor, memory, disk, and network resources. A media stream manager (207), in response to the create request, creates a multimedia stream. The session manager, in response to the resources being allocated, and the multimedia stream being created, launches a selected one of a plurality of multimedia services in the plurality of multimedia servers. The selected service provides multimedia information to the set-top box via the multimedia stream. The system includes a memory storing the plurality of multimedia services in a hierarchical tree structure having nodes representing composite and elemental services.

摘要： There is provided a means to preserve the multicast address of a frame on a first communications system having a large multicast address space when the frame is forwarded onto a second communications system having a small multicast address space. The invention comprises a connection apparatus for connecting a first communications system with a second commmunications system and has a means for receiving at least one first frame from the first communications system, the at least one first frame having a multicast destination address, the multicast destination address requiring the at least one first frame to be transmitted onto the second communications system. Also there is a means for writting a representation of the multicast address into a second frame and for transmitting the second frame onto the second communications system.

摘要： An occurrence of a predefined object in an image is recognized by receiving image data, convolving the image data with a set of prdefined functions to analyze the image data into occurences of predefined elementary features, and examining the occurrences for an occurrence of a predefined combination of the elementary features that is characteristic of the predefined object. Preferably the image data are convolved directly with a first predefined function to determine blob responses, and a second predefined function to determine ganglia responses indicating edges of objects. Then the ganglia responses are convolved with a third predefined function to determine simple responses indicating lines in the image, and the simple responses are combined with the ganglia responses to determine complex responses indicating terminated line segments in the image.

摘要： Frame processing apparatus, and a related method for its operation, for use in a station connected to a token ring network, to ensure rapid stripping of frames from the network without reference to source addresses in the frames, and in spite of the possible presence of extraneous no-owner frames on the network. The adverse effects of extraneous no-owner frames are avoided by any of three techniques. First, transmitted information frames are preceded by a start strip delimiter frame and followed by an end strip delimiter frame. The process strips all incoming frames (except tokens and ring initialization frames, which are specially handled), but does not count the stripped frames until the start strip delimiter frame is detected. Therefore, extraneous frames preceding the transmitted information frames will be stripped but not counted, and all of the transmitted frames will be stripped. In another approach, an estimated stripping time is used to terminate stripping. Frame counters are not then needed and extraneous frames will be stripped prior to the desired information frames. A third approach is to preset the transmitted frame count to some selected value, so that more frames will be stripped than were transmitted. Thus, preceding extraneous frames will be stripped, but the end strip delimiter will still terminate stripping and preclude overstripping.
