Patent number: 9531986Abstract: A method and apparatus for identifying devices using a bitmap are disclosed. In one embodiment, the method comprises: accessing a memory to obtain one or more bitmaps that map each bit location in the bitmap to an index value, where one index value is assigned to each remote wireless media device of a wireless network in a wireless communication system; and examining those bitmaps and determining at least one characteristic of a remote wireless media device and a device identifier that identifies the remote wireless media device in the wireless network based on the bit position in those bitmaps.Type: GrantFiled: June 30, 2008Date of Patent: December 27, 2016Assignee: SiBEAM, Inc.Inventors: In Sung Cho, Kumar Mahesh, Prakash Kamath, Jeffrey Gilbert, Rob Frizzell

Patent number: 9264762Abstract: An apparatus, system and method for performing dispatch operations using a signal physical interface are disclosed. In one embodiment, the apparatus is for use in a wireless communication system for communicating with a wireless network and comprises a host processor, a transceiver, a physical interface coupling the host processor and the transceiver, and a memory accessible by the host processor and the transceiver to exchange information between the host processor and the transceiver. The transceiver is operable to store data in the memory for the host processor to send data to the host processor using the memory and asserts a control signal to the host processor to notify the host processor that the memory contains data for the host processor, and the host processor is operable to access the memory to obtain the data thereafter.Type: GrantFiled: June 30, 2008Date of Patent: February 16, 2016Assignee: SiBEAM, Inc.Inventors: In Sung Cho, Kumar Mahesh, Prakash Kamath, Jeffrey Gilbert, Rob Frizzell

Patent number: 9065682Abstract: A media access controller (MAC) generates a composite packet having an optimized format for carrying audio, video, and data traffic. A header portion of the composite packet is encoded separately from a data portion of the composite packet. A physical device interface (PHY) is coupled to the MAC. The PHY encodes and decodes between a digital signal and a modulated analog signal. The PHY comprises a high rate physical layer circuit (HRP) and a low rate physical layer circuit (LRP). A radio frequency (RF) transmitter is coupled to the PHY to transmit data.Type: GrantFiled: October 31, 2007Date of Patent: June 23, 2015Assignee: Silicon Image, Inc.Inventors: Kumar Mahesh, Karthik Krishnaswami, Karen Wang, Jeffrey M. Gilbert, Chuen-Shen Shung

Patent number: 8750241Abstract: A wireless station has a media access controller (MAC) and a concurrent association manager. The concurrent association manager concurrently associates the wireless station with two or more wireless coordinators. Each wireless coordinator forms its respective wireless network. The concurrent association manager sets the wireless station in a sleep mode operation with respect each wireless network and detects a selection for operation with respect to one of the wireless coordinator.Type: GrantFiled: December 7, 2007Date of Patent: June 10, 2014Assignee: SiBeam, Inc.Inventors: Kumar Mahesh, Jeffrey M. Gllbert, James Gilb

Patent number: 8116333Abstract: A method and apparatus for performing connection control in a wireless communication system is described. In one embodiment, an apparatus is used in a wireless communication system for communicating with a wireless network, and the apparatus comprises a host processor, a transceiver, a physical interface coupling the host processor and the transceiver; and a memory accessible by the host processor and the transceiver to exchange information between the host processor and the transceiver. The memory has multiple banks that include: a first bank to store information being transferred from the host processor to the transceiver, and a second bank to store information being transferred from the transceiver to the host processor, the second bank being different than the first bank, to facilitate full-duplex communication of packet data between the host processor and the transceiver.Type: GrantFiled: June 30, 2008Date of Patent: February 14, 2012Assignee: Sibeam, Inc.Inventors: In Sung Cho, Kumar Mahesh, Prakash Kamath, Jeffrey Gilbert, Rob Frizzell

Patent number: 7948961Abstract: A wireless content protection system includes a coordinator, a source device, and a sink device. The coordinator includes a scheduler. The source and sink devices each have a content protection manager. One of the content protection manager allocates and releases bandwidth via the coordinator for a test message and a response message for a round-trip time computation. The test message is transmitted in a source-to-sink channel time block. The response message is transmitted in a sink-to-source channel time block. The round-trip time is the period between the end of the source-to-sink channel time block and the beginning of the sink-to-source channel time block.Type: GrantFiled: January 25, 2008Date of Patent: May 24, 2011Assignee: Sibeam, Inc.Inventors: Kumar Mahesh, Karthik Krishnaswami, Karen Wang, Jeffrey M. Gilbert, Chuen-Shen (Bernard) Shung, Chih-Yuan Hsieh, Kyeong Ryu, Prakash Kamath
