  • Patent number: 9065682
    Abstract: 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.

  • Patent number: 8014416
    Abstract: A radio frequency (RF) transmitter is coupled to and controlled by a processor to transmit data. A physical layer circuit is coupled to the RF transmitter to encode and decode between a digital signal and a modulated analog signal. The physical layer circuit comprises a high rate physical layer circuit (HRP) and a low rate physical layer circuit (LRP). The low rate channels generated by the low rate physical layer circuit (LRP) share a same frequency band as a corresponding high rate channel generated by the high rate physical layer circuit (HRP).

  • Patent number: 7904117
    Abstract: A method and apparatus is disclosed herein for wireless communication with adaptive beamforming. In one embodiment, the apparatus comprises a processor, a radio frequency (RF) transmitter having a digitally controlled phased array antenna coupled to and controlled by the processor to transmit content using adaptive beamforming, and an interface to a wireless communication channel coupled to the processor to communicate antenna information relating to the use of the phased array antenna and to communicate information to facilitate playing the content at another location.

  • Patent number: 6917548
    Abstract: A process of repairing defects in linked list memories including selecting one of a group of the linked list memories and an additional memory, as a defect marking memory, detecting faults in rows of the defect marking memory, and storing row addresses having at least one fault in defect address registers. The method detects faults in rows of other linked list memories, where the other linked list memories are the linked list memories other than the defect marking memory, and stores a marking code for each row address of the other linked list memories in the defect marking memory. The defect address registers and the defect marking memory are searched when addresses of the linked list memories are linked and row addresses having a specific marking code skipped in the linking process.
