| Abstract: | H.264/AVC is gradually applied in practice and it has a wide range of applications in logo insertion transcoding.A fast logo insertion transcoding scheme is provided,which utilizes the idea of re-loss-free video coding and effectively reuses of encoding parameters of input stream.Experimental results show that the proposed H.264/AVC logo insertion solution can effectively implement the application of logo insertion in H.264 video stream. |
