摘要： A network switch configured for switching data packets across multiple ports uses decision making logic to generate frame forwarding decisions. The switch buffers data frame header information in an internal memory for processing by the decision making logic. The switch employs a modular architecture that enables the decision making logic to perform its processing independently from other logic functions of the switch.

摘要： A test system includes a switch emulator, a network test device, and an interface converter. The switch emulator is configured for transmitting first network data on a first media independent interface based on a first interface clock, and the network test device configured for transmitting second network data on a second media independent interface based on a second interface clock. The interface converter, having inverted media independent interfaces, is configured for transferring the first and second network data between the first and second media independent interfaces, and supplying the first and second interface clocks based on an external clock generated by the switch emulator. Hence, network data can be passed between the switch emulator and the network test device according to network protocols, even if the switch emulator is operating at relatively slow speeds.

摘要： Multiple network switches are configured having memory interfaces that transfer segmented packet data to each other via a unidirectional data bus ring connecting the network switches in a single ring or “daisy chain” arrangement. The memory interfaces are also configured for transferring the segmented packet data to respective local buffer memories for temporary storage. The memory interfaces transfer the data units according to a prescribed sequence, optimizing memory bandwidth by requiring only one read and one write operation to and from the local buffer memory for each segmented packet data being received and transmitted through the switches.

摘要： A switching system includes a multiport module having an address table for storing network addresses, and a host processor configured for selectively swapping the stored network addresses in the address table to an internal memory that serves as an overflow address table for the multiport switch module. The address table internal to the multiport module is configured for storing a prescribed number of network addresses for high-speed access, for example the most frequently-used network addresses. The host processor, configured for controlling the storage of network addresses between the address table and the external memory, uses the external memory as the overflow address table for storage of less frequently-used network addresses, for example addresses of network devices that transmit little more than periodic “keep-alive” frames. Hence, a large number of addresses may be managed by the switching system, without the necessity of an unusually large on-chip address table.

摘要： A network switch configured for switching data packets across multiple ports and for supporting trunked data paths uses an address table to generate frame forwarding information. When a link in a trunked data path experiences a change in its operating status, the trunk data path is reconfigured to reflect the current operating conditions, without reprogramming the address table or powering down the switch.

摘要： Techniques for efficient database formation and search in applications embedded in a media device are provided. The search may be performed synchronously with presentation of media programming content on a nearby media presentation device. A mobile media device captures some temporal fragments of the presented audio/video content on its microphone and camera, and then generates query fingerprints for the captured fragment. A local reference database resides on the mobile media device and a master reference database resides on a remote server with a most recent chunk of reference fingerprints transferred dynamically to the local mobile media device. A chunk of the query fingerprints generated locally on the mobile media device are searched on the local reference database for continuous content search and identification. The method presented automatically switches between the local search on the mobile media device and a remote search on an external search server.

摘要： A mobile device responds in real time to media content presented on a media device, such as a television. The mobile device captures temporal fragments of audio-video content on its microphone, camera, or both and generates corresponding audio-video query fingerprints. The query fingerprints are transmitted to a search server located remotely or used with a search function on the mobile device for content search and identification. Audio features are extracted and audio signal global onset detection is used for input audio frame alignment. Additional audio feature signatures are generated from local audio frame onsets, audio frame frequency domain entropy, and maximum change in the spectral coefficients. Video frames are analyzed to find a television screen in the frames, and a detected active television quadrilateral is used to generate video fingerprints to be combined with audio fingerprints for more reliable content identification.

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.
