Bit stream extraction based on video content method in the scalable extension of H.264/AVC

The bit stream extraction plays an important role in Scalable Video Coding (SVC). The video content is an important factor for video coding efficiency but it is ignored in current video coding methods. Therefore, in this paper, we proposed an equivalent MSE method to extract sub streams in the temporal and spatial enhancement layers. When the Motion Vectors (MVs) are large in one video, a larger frame rate is necessary to maintain the continuity of the object movement which makes no jump in visual sense. In this sense, sub streams extraction more temporal enhancement layers have to be satisfied. On the other hand, if there are some larger high-frequency components in a single frame of the video, it should try to meet the extraction requirement in spatial enhancement layer. This method has the advantage of considering the contents of the video, which can effectively improve the coding performance and quality. The experimental results demonstrate that the quality of reconstructed video has been improved significantly by using the equivalent MSE method when extracting bit stream arbitrarily at the same bandwidth. © 2011 ACADEMY PUBLISHER.
