  • Patent number: 8553154
    Abstract: An apparatus comprising a first circuit, a processing circuit and a conversion circuit. The first circuit may be configured to generate a first intermediate signal in a second format in response to an input signal in a first format. The processing circuit may be configured to generate a second intermediate signal and a third intermediate signal in response to the first intermediate signal. The conversion circuit may be configured to generate an output signal in the first format in response to the second intermediate signal and the third intermediate signal. The processing circuit may be configured to implement color blending on the second intermediate signal in the second format prior to conversion to the first format and pass the third intermediate signal without color blending.
    Type: Grant

  • Publication number: 20060281487
    Abstract: A method for receiving high data rate wireless communication transmissions begins by receiving a plurality of radio frequency (RF) signals in accordance with a wireless communication standardized data rate on a plurality of RF channels. The method continues by converting each of the plurality of RF signals into a plurality of signals. The method continues by processing the plurality of signals at baseband or near baseband into media access control (MAC) data, wherein a number of the plurality of signals corresponds to an integer multiple. The method continues by processing the MAC data at a combination of wireless communication standardized data rates to produce recovered data.

  • Publication number: 20060067418
    Abstract: A wireless communication device capable of receiving data using non-standard data includes a receiver section, a demodulation mapping module, a decoding module, and a rate determination module. The receiver section is operably coupled to convert a radio frequency signal into a digital signal. The demodulation mapping module is operably coupled to demodulate the digital signal to produce demodulated data. The decoding module is operably coupled to decode the demodulated data based on the coding rate to produce decoded data. The rate determination module is operably coupled to determine the coding rate from at least one of the digital signal and the demodulated data, wherein the coding rate is one of a plurality of standard coding rates or a non-standard coding rate that is selected for a given transmission.
