Abstract
Methods, systems, and terminal devices for transmitting information are provided. An exemplary system includes a sending end and at least one receiving end. The sending end is configured to obtain audio data to be transmitted, encode the obtained audio data according to an M-bit unit length, and use a pre-set cross-platform audio interface to control an audio outputting device of the sending end to send the encoded audio data to the at least one receiving end. The M-bit unit length is an encoding length corresponding to each frequency of a number N of frequencies, N is greater than or equal to 2, and M is greater than 0. The at least one receiving end is configured to use the pre-set cross-platform audio interface to control an audio inputting device of the at least one receiving end to receive the encoded audio data.
