A frame type identification method, the RTP package includes a transmitting device to detect GOP parameters to send the corresponding GOP, the GOP parameters are used to describe the distribution pattern of GOP in the frame; a transmission device to timestamp I-frame detection point sends the GOP of the time stamp; get the first RTP packet time stamp I will detect the GOP and the GOP in comparison, if the same, will be the first RTP packet marking for I-frame, and according to the GOP parameters of the frame type other RTP the GOP package. In addition, a device and a system for identifying RTP packet frame types are provided. Through the method provided by the embodiment of the invention, the frame type can be successfully obtained without needing to go deep into the RTP load, thereby improving the success rate of detecting the RTP packet frame type and reducing the detection difficulty.
