According to the method, an efficient set of virtual output queues (at most one virtual output queue per ingress adapter) is selected, while keeping the algorithm simple enough to allow its implementation in fast state machines. For determining a set of virtual output queues that are each authorized to send a packet, the algorithm is based upon degrees of freedom characterizing states of ingress and egress adapters. For example, the degree of freedom, derived from the collapsed virtual output queuing array, could represent the number of egress ports to which an ingress port may send packet, or the number of ingress ports from which an egress port may receive packets, at a given time. Analyzing all the ingress ports holding at least one data packet, from the lesser degree of freedom to the greater degree of freedom, the algorithm determines as many virtual output queues as possible, in the limit of the number of ingress ports (an ingress port may send only one packet per packet-cycle). | 2009-06-04 |
| 20090141734 | METHOD AND SYSTEM FOR A CONVERGED INFINIBAND OVER ETHERNET NETWORK - A method of providing a converged InfiniBand over Ethernet (IBOE) network. An IBOE switch receives a data packet.

The translation utility generates an Ethernet packet and encapsulates an InfiniBand link layer packet before sending the packet. If the data packet is received by the IBOE switch from the Ethernet network, the translation utility removes the Ethernet header from the packet and looks up a LID corresponding to the MAC address. The translation utility calculates an outbound port number and sends the packet. | 2009-06-04 |

The evaluation value information on the motion vectors is generated from pixel value correlation information that has been one of generated and limited using a movement direction of the pixels. The motion vector extracting unit is configured to extract motion vectors as candidates from a plurality of motion vectors based on the evaluation value information formed by the evaluation value information forming unit. The motion vector deciding unit is configured to decide motion vectors to be assigned to pixels in a frame from the motion vectors extracted as the candidates by the motion vector extracting unit. | 2009-06-04 |
| 20090141803 | VIDEO FRAME ENCODING AND DECODING - A video frame arithmetical context adaptive encoding and decoding scheme is presented which is based on the finding, that, for sake of a better definition of neighborhood between blocks of picture samples, i.e. the neighboring block which the syntax element to be coded or decoded relates to and the current block based on the attribute of which the assignment of a context model is conducted, and when the neighboring block lies beyond the borders or circumference of the current macroblock containing the current block, it is important to make the determination of the macroblock containing the neighboring block dependent upon as to whether the current macroblock pair region containing the current block is of a first or a second distribution type, i.e., frame or field coded. | 2009-06-04 |
| 20090141804 | NEIGHBOR MANAGEMENT FOR USE IN ENTROPY ENCODING AND METHODS FOR USE THEREWITH - An entropy coding module is provided for use in a video encoder that encodes a video input signal based on a plurality of macroblocks derived from the video input signal. The entropy coding module includes an entropy coder that generates entropy encoded data from discrete transformed coefficients for the plurality of macroblocks. A neighbor management module stores neighbor data for at least one macroblock of the plurality of macroblocks for retrieval by the entropy encoder, when operating on at least one neighboring macroblock of the plurality of macroblocks. | 2009-06-04 |
| 20090141805 | Method and system for fingerprinting digital video object based on multiersolution, multirate spatial and temporal signatures - A method and system for generating a spatial signature for a frame of a video object. The method includes obtaining a frame associated with a video object, and dividing the frame into a plurality of blocks. The plurality of blocks corresponds to a plurality of locations respectively, each of the plurality of blocks includes a plurality of pixels, and the plurality of pixels corresponds to a plurality of pixel values respectively. Additionally, the method includes determining a plurality of average pixel values for the plurality of blocks respectively. Each of the plurality of blocks corresponds to one of the plurality of average pixel values. Moreover, the method includes processing information associated with the plurality of average pixel values and determining a plurality of comparison values for the plurality of blocks respectively based on at least information associated with the plurality of average pixel values. | 2009-06-04 |
