Summary:The application provides a video data transmission method and apparatus. The video data includes an I frame, a P frame, and a B frame. The method is characterized in that the method comprises: a video sending terminal and a video receiving terminal establish video transmission channels including a safe transmission channel and a non-safe transmission channel; the I frame is transmitted by the safe transmission channel and the P frame and the B frame are transmitted by the non-safe transmission channel; and the video data are recovered according to the I frame, the P frame, and the B frame. According to the method and apparatus, the I frame is only transmitted by the safe transmission channel by using the characteristic that the P frame and the B frame can not be decoded without the I frame, so that the video data safety is guaranteed and the encryption/decryption data volume is reduced. Therefore, the processing efficiency of video data is improved and the system resource consumption is reduced.
