An improved FGS (Fine Granular Scalability) coding method is proposed in thisletter, which is based on human visual characteristics. This method adjusts FGS coding frame rateaccording to the evaluation of video sequences so as to improve the coding efficiency and subjectperceived quality of reconstructed images. Finally, a fine granular joint source channel coding This method adjusts FGS coding frame rateaccording to the evaluation of video sequences so as to improve the coding efficiency and subjectperceived quality of reconstructed images.
