Abstract:
1. A method of presenting media content comprising: determining a characteristic of frequencies of a frequency domain representation of audio output by a first media presentation device that may contain a code representative of at least one of first media content or a broadcaster of the first media content; normalizing, across code bands, the characteristic of the frequencies of the frequency domain representation in a code band that may contain the code, the normalization being carried out against a threshold characteristic of a frequency in that code band; summing the normalized characteristics of the corresponding frequencies to identify the frequency with the largest sum; determining that the identified frequency is representative of the code; obtaining second media content based on the code; and presenting the second media content on a second media presentation device different from the first media presentation device while the first media content is presented on the first media presentation device.
