Claim 0:
1. A data transmission system through a visible light for providing a data transmission between a surface and an underwater of a swimming pool, wherein the data transmission system comprises:
at least one digital audio source configured to obtain a first audio signal from stored data or stream data,
at least one modulator configured to receive the first audio signal from the at least one digital audio source and convert the received first audio signal into a first electrical signal,
at least one light source configured to receive the first electrical signal from the at least one modulator and the at least one light source is configured to convert the electric signal into an optical signal and transmit the optical signal, wherein the at least one light source is placed on a ceiling of an indoor swimming pool,
at least one light sensor configured to receive underwater the optical signal transmitted from the at least one light source and convert the received optical signal into a second electrical signal,
at least one demodulator configured receive the second electrical signal and retrieve a data signal from a baseband processing of the received second electrical signal,
at least one audio converter configured to convert the data signal into a second audio signal, and
at least one output unit configured to play the second audio signal generated by the at least one audio converter.
