摘要： The overall architecture and details of a scalable video fingerprinting and identification system that is robust with respect to many classes of video distortions is described. In this system, a fingerprint for a piece of multimedia content is composed of a number of compact signatures, along with traversal hash signatures and associated metadata. Numerical descriptors are generated for features found in a multimedia clip, signatures are generated from these descriptors, and a reference signature database is constructed from these signatures. Query signatures are also generated for a query multimedia clip. These query signatures are searched against the reference database using a fast similarity search procedure, to produce a candidate list of matching signatures. This candidate list is further analyzed to find the most likely reference matches. Signature correlation is performed between the likely reference matches and the query clip to improve detection accuracy.

摘要： Scaleable video sequence processing with various filtering rules is applied to extract dominant features, and generate unique set of signatures based on video content. Video sequence structuring and subsequent video sequence characterization is performed by tracking statistical changes in the content of a succession of video frames and selecting suitable frames for further treatment by region based intra-frame segmentation and contour tracing and description. Compact representative signatures are generated on the video sequence structural level as well as on the selected video frame level, resulting in an efficient video database formation and search.

摘要： The invention provides a novel method of data processing in a multiport communication system having a decision making engine for controlling data forwarding between the receive ports and at least one transmit port. Data blocks representing received data packets are placed in data queues corresponding to the receive ports. The data queues are transferred one at a time in successive time slots to logic circuitry that determines the transmit ports. The time slots are dynamically allocated to the data queues in accordance with data traffic at the corresponding receive ports.

摘要： Multiple network switch modules have memory interfaces configured for transferring packet data to respective local buffer memories via local memory controllers. The local memory controllers are connected to each other to form a signal memory pool for transfer among each other data units of data frames received from different network switch modules. Each of the controllers are also connected to a corresponding local buffer memory and either write received data units in the corresponding local buffer memory or transfer the received data units to other controllers that, in turn, write the data units in their corresponding local buffer memory. The local memory controllers transfer and write and read the data units according to a prescribed sequence, optimizing memory bandwidth by concurrently executing a prescribed number of successive memory writes or memory reads.

摘要： A novel system and method of automatically detecting a change in network node connection in a multiport data switching system having receive ports for receiving data packets from network nodes, and a decision making engine for controlling data forwarding. Data blocks representing received data packets are placed in data queues corresponding to the receive ports. The data queues are transferred to logic circuitry for processing in accordance with a predetermined algorithm. This processing includes automatically detecting a change in connection between at least one of the network nodes and at least one of the receive ports, based on a search of an address table having address information relating to the receive ports. The address table may be searched for an address entry having a source address and VLAN address information that match a source address and VLAN address information of the received data packet. Receive port data written in the address entry having matching address information are checked to determine whether these data identify a receive port arranged in the same trunk as the receive port, from which the data packet is transferred. The address entry is automatically updated with new information, if the receive port identified in the address entry and the actual receive port are in different trunks.

摘要： A novel method of providing interleaved access to an address lookup table in a multiport communication system having a decision making engine for controlling data switching between receive and transmit ports. A source address (SA) lookup logic circuit and a destination address (DA) connected in a pipeline are enabled to alternately access the address table. An arbitration circuit provides the SA and DA logic circuits with automatic access to the address table in alternate time slots allocated to these logic circuits. Also, the arbitration circuit enables an aging circuit and a host processor to periodically access the address table in pre-selected time slots.
