A multicast transmission method for information to be transmitted, comprising the steps of: dividing a coding sequence of information to be transmitted into a plurality of code strings, and defining each code string and a corresponding index string allocated thereto and representing an index sequence as a coding unit; constructing a reference frame based on a multicast data frame format; constructing an information frame based on the multicast data frame format, so as to enable a destination address domain thereof to contain the first part content of the coding unit, and enable the difference between the frame length thereof and the frame length of the reference frame to contain the remaining part of the content of the coding unit; and transmitting the reference frame and the information frame. Also disclosed is a multicast data frame information extraction method according to a principle in the inverse of the method. In addition, also disclosed are implementation schemes for corresponding intelligent control terminals and intelligent devices corresponding to the two methods. By means of the present invention, information transmission is conducted using a multicast data frame without depending on a pre-established connection between the two transmission parties, thereby simplifying the communication process, and making the effect of communication between devices quick and efficient. |
