Patent number: 9280806Abstract: Aspects of an edge smoothing block filter and combinations of the filter with a motion compensated temporal filter are described. In one embodiment, edge smoothing block filtering includes selecting a current pixel to be filtered and selecting a candidate pixel within a search area about the current pixel. The edge smoothing block filtering generally seeks to identify candidate pixels having surrounding pixels similar to pixels surrounding the current pixel. The edge smoothing block filtering further computes a cost difference between pixels within a candidate pixel neighborhood and pixels within a current pixel neighborhood, and filters the current pixel based on the cost difference. Aspects of the filters and filter element combinations may preserve edges and textures adaptively based on image content. For example, diagonal or curved image edges may be filtered along edges while texture is preserved along the edges.Type: GrantFiled: February 7, 2013Date of Patent: March 8, 2016Assignee: BROADCOM CORPORATIONInventors: Jaewon Shin, Brian Schoner

Patent number: 9281869Abstract: A network repeater is configured to repeat data packets in a broadcast mode without generating a significant broadcast storm. The network repeater is configured to detect a characteristic of a received data packet. The data packet characteristic is compared with valid copies of packet characteristics previously stored in a packet registry. During a delay period, if a valid copy of the detected characteristic is found in the packet registry, then it is assumed that the packet is being received for the second time and the data packet is not repeated in the broadcast mode. If a valid copy of the detected characteristic of the data packet is not found in the packet registry, then the characteristic is stored in the packet registry and the data packet is repeated in a broadcast mode.Type: GrantFiled: May 24, 2013Date of Patent: March 8, 2016Assignee: BROADCOM NETWORKS SPAIN, S.L.Inventors: Veronica Romero, David Ruiz Lopez
