In this research, we proposed a method of transform a single-slice structure to multiple-slice structure for H.264/AVC baseline video stream. Due to huge channel error and packet loss in wireless network, the process of entropy decoding in H.264 cannot decode correctly in such situation. It may cause huge damage and error propagation at the frame where errors occur, and those frames who make references to that frame. Based on H.264/AVC specification, slices cannot make a cross reference in the same frame. Hence, to transfer single slice structure into multiple slice structure, it is required to change slice references and insert new slice header. The proposed method can be used to transfer video stream over error channel, and recover the damaged frames with high quality.
