  Abstract

When providing fixed/mobile broadcast convergence 3DTV services in a terrestrial broadcasting environment, the problem of image quality of asymmetric binocular images has always emerged. To solve this problem, a conditional replenishment algorithm using the correlation of binocular images has been studied. Existing algorithms have improved image quality by compensating the high-definition reference image in a parallax manner and applying it to the low-definition additional image. This paper proposes an extended algorithm that uses temporal correlation to encode conditional replenishment algorithms more efficiently. By using a high-definition additional image that has already been compensated and restored at the previous time, motion compensation is performed on the low-definition additional image of the present time. The proposed algorithm showed Bit saving performance of 19.8% and 30.5% on average for real-film and animation clips 540P and 1080P clips, respectively, compared to previous algorithms.
