Abstract: This application provides an interaction information transmission method and apparatus. The method includes: receiving, by a calling terminal from an RBT-AS, an SDP message including interaction information related to a video ring back tone; receiving, by the calling terminal from the RBT-MRS, a video ring back tone media stream including the video ring back tone; and playing, by the calling terminal, the video ring back tone in a display interface, and displaying interaction content related to the interaction information. Since the RBT-AS configures the interaction information into the SDP message and sends the SDP message to the calling terminal, the calling terminal does not need to perform decoding and can directly obtain the interaction information and the RBT-AS does not need to encode the interaction information either. Therefore, encoding and decoding processes are not required at a transmit end and a receive end respectively, avoiding extra processing overheads.
