摘要： A wideband receiver system comprises a wideband analog-to-digital converter (ADC) module and a digital frontend (DFE) module. The wideband ADC is configured to concurrently digitize a band of frequencies comprising a plurality of desired channels and a plurality of undesired channels. The DFE module is coupled to the digital in-phase and quadrature signals. The DFE module is configured to select the plurality of desired channels from the digitized band of frequencies, and generate an intermediate frequency (IF) signal comprising the selected plurality of desired channels and having a bandwidth that is less than a bandwidth of the band of frequencies, where the generation comprises frequency shifting of the selected plurality of desired channels. The IF signal may be a digital signal and the DFE is configured to output the IF signal via a serial or parallel interface.

摘要： Circuitry for detecting an audio standard of a sound intermediate frequency signal includes an intermediate frequency to baseband circuit, a detection circuit and a demodulator/decoder. The intermediate frequency to baseband circuit is configured to process the sound intermediate frequency signal to generate a main tone and a sub-tone. The detection circuit is configured to determine if the sound intermediate frequency signal belongs to a first standard or a second standard according to if the sub-tone has a pilot signal or a digital frame, to generate a detection result. The demodulator/decoder is configured to demodulate/decode at least the main tone to generate an output audio signal.

摘要： Methods (900, 1000) and apparatuses (110, 120, 400) are provided for transmitting and receiving a signal. The method (900) of transmitting a signal includes modulating (920) data into a plurality of modulation symbols to generate a signal, the data including time synchronization information including one of a time offset parameter and a frame length parameter selected according to a frame length mode parameter, and transmitting (930) the signal over a communication medium. The method (1000) of receiving a signal includes receiving (1010) a signal over a communication medium, and demodulating (1020) the signal to generate a plurality of demodulated symbols, the demodulated symbols including data, the data including time synchronization information including one of a time offset parameter and a frame length parameter selected according to a frame length mode parameter.

摘要： In one example, a remote tuner module includes: a first tuner to receive, process and demodulate a first radio frequency (RF) signal to output an analog audio signal, and to receive and process a second RF signal to output a first downconverted modulated signal; a second tuner to receive and process the second RF signal to output a second downconverted modulated signal; a demodulator circuit coupled to the first and second tuners to demodulate and link the first and second modulated signals, to output a linked demodulated signal. The remote tuner module may further include a gateway circuit coupled to at least the demodulator circuit to output the analog audio signal and the linked demodulated signal.

摘要： A display device may include a display panel, N receiving antennas integrated with the display panel, where N is an integer greater than 2, a communication module, and a display driver. The communication module receives a video communication signal using a subset of receiving antennas of the N receiving antennas and an audio communication signal using at least one receiving antenna of the N receiving antennas that is different from the subset of receiving antennas and generates original video data based on the video communication signal and audio data based on the audio communication signal. The display driver receives the original video data from the communication module and drives the display panel based on the original video data.
