That is, the broadcast content providing server 300 inserts a sound code using a spread spectrum method, which will be described below.

Spread Spectrum (Spread Spectrum) is a type of communication encryption technology, a secure communication method that can not demodulate the received signal without a specific encryption. The spread spectrum can communicate without interference by using each pseudo noise (PN) sequence.

Spread Spectrum is a technique for widening the frequency band of a specific signal. It is possible by using digital data of a specific frequency in various ways to widen the frequency band or shift the center frequency.

There are various kinds of spread spectrum modulation methods, among them, a direct sequence method and a frequency hopping method.

The direct sequence method is a direct spreading method, and multiplies the digital transmission signal by multiplying a pulse string having a much shorter period to occupy a large frequency bandwidth. After receiving the spread signal, the original signal is demodulated by multiplying again the pulse train that exactly matches the pulse train used for transmission. The pulse train itself used for the modulation and demodulation is a kind of cipher, and without this cipher, the original signal cannot be demodulated.

In this case, the pulse train used for the modulation and demodulation may be a Pseudo Noise (PN) sequence as a pseudo random noise signal, for example.
