description The invention discloses a data encoding and decoding method and system. The method comprises the following steps: encoding a frame to be encoded according to a reference frame to obtain a code streamto be transmitted, the code stream to be transmitted comprising: a first picture identifier used for representing the frame to be encoded; generating code stream information according to the first picture identification code in the code stream to be transmitted and the second picture identification code of the reference frame; and packaging the to-be-transmitted code stream, and generating an extension head according to the code stream information to obtain a to-be-transmitted data packet. According to the invention, the technical problem that the video display frame rate of the terminal is reduced in the decoding process due to packet loss in the transmission process is solved. 本发明公开了一种数据编解码的方法和系统。其中，该方法包括：依据参考帧对待编码帧进行编码，得到待传输码流，其中，待传输码流包括：第一图片标识，第一图片标识用于表示待编码帧；依据待传输码流中的第一图片标识码和参考帧的第二图片标识码生成码流信息；对待传输码流进行封装，并依据码流信
