It is not scalable and from the image signal which is encoded scalable method and the device in order to form the image signal which is encoded

摘要

Topic It was constituted offer the method and the product in order to correct, the data in order to obtain the scalable image signal from the image signal which is not scalable, with the standard image signal and the emphasis image signal of the deck.SolutionsIt was constituted from the image signal which is not scalable, by with the standard image signal and the emphasis image signal of the deck the scalable image signal data correction method in order cost effectively to obtain. Particular method cascade condition or was combined in series in order to forward the particular standard image signal, in each of particular attenuation step in order to forward one of the particular emphasis image signals from the encoding error which is formed with the attenuation step and each attenuation step of the deck which is applied to the factor which forms the image signal which is not particular scalable relation the re-encoding conversion step which is attached and, it possesses. Because the scalable image signal is directly formed from the image signal which is encoded particularly, the movement compensation which is done until recently with method of technology the expensive processing step like movement appraisal already is not necessary. It is possible to increase the number of emphasis image signals easily, other attenuation step and re-encoding conversion step cascade condition or by combining in series. Selective figure Figure 1
