Abstract (en)

[origin: WO9922512A1] A method for transferring information from an information provider (420) to an information consumer in a highly efficient manner by means of a television signal (401, 402, 404) without adversely effecting the intended primary receivers of the television signal. The used television signal comprises a video signal (401), an analog sound signal (402), and a digitally coded sound signal (403) such as NICAM as an additional service to the video and analog sound signal. According to the invention the digitally coded sound signal is replaced with the information (400) to be transferred coded in such a way it cannot be mistaken by the primary receivers for the digitally coded sound.
