Abstract: A network switch configured for switching data packets across multiple ports uses an internal memory to store frame headers for processing by decision making logic. The internal memory stores frame headers in a queue configured to store a number of the frame headers for each of the receive ports. A scheduler is included for facilitating the transfer the data from the queues to the decision making logic according to a predetermined priority. The scheduler is also able allocate the time slots in accordance with data traffic at the corresponding receive ports to maximize data throughput.

Abstract: A novel method of servicing multiple data queues having different priorities is provided in a network switch. A dequeuing logic circuit services the data queues in a round-robin fashion. Programmable number of data packets is selected from each data queue in each cycle. The dequeuing logic circuit compares the number of data packets selected from a current data queue in a current cycle with the preprogrammed number of data packets set for the current queue, and selects a data packet from the current data queue only if the number of packets selected from the current data queue in the current cycle is less than the preprogrammed number. Selection of a data packet from the current data queue is bypassed, processing a next data queue, if the number of packets selected from the current data queue in the current cycle is not less than the preprogrammed number.

Abstract: A novel method of data forwarding is provided in a network switch having multiple ports including at least one backbone port for data communications with backbone network nodes. Destination information of a received data packet is compared with a predetermined set of address data in an address table. If the packet's destination information is not found in the address table, the received data packet is forwarded to the backbone port. Further, the source address information of the received data packet may be compared with the address table. In a regular mode of operation, if the packet's source address information is not found in the address table, this information is added to the address table. However, in a backbone mode of operation, the address information of a data packet received from the backbone port is prevented from being added to the address table. The switch may have backbone ports provided for multiple VLANs supported by the switch. A first data packet received from a first VLAN is forwarded to at least one backbone port for that VLAN, if the packet's destination information is not found in the address table. Similarly, a second data packet received from a second VLAN is forwarded to at least one backbone port for the second VLAN if the packet's destination information is not found in the address table. A backbone vector storage is provided for identifying backbone ports for the multiple VLANs supported by the switch.

Abstract: An apparatus and method are disclosed for regulating the flow of data between plural network stations through a network switch. A receive port functions to receive data frames from a first network station, and a transmit port outputs the received data frames to a second network station. A programmable threshold register is provided for storing a threshold value that indicates a saturation level for the internal resources of the transmit port. Control circuitry is used to monitor the internal resources of the transmit port and determine whether or not the threshold value has been reached. If the threshold value has been reached, then the control circuitry will implement a flow control process that causes the first network station to discontinue transmission of data frames to the transmit port until the internal resources of the transmit port fall below the threshold value.

Abstract: 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.

Abstract: 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.

Abstract: 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.
