Abstract :
In wireless video streaming application, video information may be corrupted by a noisy channel. By introducing error resilience and error concealment techniques, many researchers have tried to eliminate quality degradation of reconstructed picture in decoding a corrupted data. On the contrary, there are relatively fewer works discussing the ways to diminish the corruption. Hence, system designers need to use different methods to restrict the error cause by channel within a tolerable extent. In other words, the system will be difficult to be implemented in practical design. In this paper, we propose a way to protect the video header information in application layer without modifying standardized syntax. Beside, we also consider channel condition of wireless transmission and propose a way to reduce redundant bits used in channel coding. By doing this, the bitstream can be simply transmitted over practical wireless network and the reconstructed picture quality outperforms the original one.
