    摘要: A method of configuring a tuner includes sampling a radio frequency and measuring at least one signal quality metric for the sampled frequency. It is determined whether there is co-channel interference on the sampled frequency based on the measurement of the at least one signal quality metric. The sampled frequency is selected as an operational frequency for the tuner if it was determined in the determining step that there is an absence of co-channel interference on the sampled frequency.

    摘要: A method of operating a radio having a plurality of station preset pushbuttons includes assigning to the preset pushbuttons a first group of radio frequencies associated with a first country. A spectrum of radio frequencies is scanned. A signal quality metric is measured for each of the scanned frequencies. A country of origin is determined for each of the scanned frequencies. A country in which the radio is disposed is ascertained dependent upon the measuring step and the determining step. If the country in which the radio is disposed is different from the first country, then either the preset pushbuttons are automatically re-assigned to a second group of radio frequencies associated with the country in which the radio is disposed, or a user is provided with an option to re-assign the preset pushbuttons to the second group of radio frequencies.

    摘要: A method of operating an audio system in an automobile includes identifying a user of the audio system. An audio recording playing on the audio system is identified. An audio setting entered into the audio system by the identified user while the audio recording is being played by the audio system is sensed. The sensed audio setting is stored in memory in association with the identified user and the identified audio recording. The audio recording is retrieved from memory with the sensed audio setting being embedded in the retrieved audio recording as a watermark signal. The retrieved audio recording is played on the audio system with the embedded sensed audio setting being automatically implemented by the audio system during the playing.
