The invention relates to a transmitting system of multimedia program preview information, which comprises a multiplexer, a modulator, transmitting equipment and a program preview generator, wherein the program preview generator is used for transmitting program preview information and a corresponding service serial number to the multiplexer; and the multiplexer is used for encapsulating video information of the program preview information in a video flow of a video band of a multiplexing subframe where the service serial number is positioned, adding program preview instruction information to aparameter set of the video flow, transmitting a multiplexing frame where the multiplexing subframe is positioned to the modulator and utilizing the transmitting equipment for transmission. A receivingterminal of the multimedia program preview information is used for receiving data of the multiplexing frame to demodulate and analyze the multiplexing subframe and analyzing the video program previewinformation from the video flow of the video band of the multiplexing subframe according to the program preview instruction information in the parameter set of the video flow of the multiplexing subframe. The invention can transmit and receive the program preview information in real time.
