Summary:In this paper, we propose a novel solution for 4K-HDTV system that combines a super-resolution system and a noise removable system. The super-resolution system consists of a total variation (TV) regularization decomposition, a shock filter, and a pulse enhancement filter, and the compression noise removable system consists of the TV regularization decomposition and a deblocking edge filter (DEF). We obtain good results in terms of picture quality. And we implement our system on GPGPU, and we achieve both noise remove and super-resolution from Full-HD to 4K-HD resolution conversion in real time. We consider this system to be a practical solution, especially for the super-resolution of HDTV broadcasting signal for devices such as 4K-HDTV receivers and PCs with 4K display panels.
