First digital contents are modulated into an audio signal in a first device, wherein the first digital contents include contact information and at least one index of at least one second digital content. The audio signal is outputted by at least one audio generator of the first device and then received by at least one audio receiver of a second device. The audio signal is demodulated in the second device to make the second device obtain the first digital contents. The second device obtains the at least one second digital content according to the at least one index of the at least one second digital contents through a wired or wireless communication."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for transmitting digital contents","description":"The invention discloses a method for transmitting digital contents between devices.
