| Popis: | A multi-format UHDTV video coding system with super resolution inter-layer prediction is described. Signaling optimal up-conversion parameters along with lower-resolution video, receivers are capable of decoding both higher- and lower-resolution videos without any help from inter-layer residuals. We developed real-time inter-layer prediction processors that calculate and signal optimal parameters on the transmission side and that up-convert low resolution video frames taking account of the signaled parameters. The system is equipped with a sophisticated optimization criterion that measures the structural similarity and the strength of ringing artifacts as well as error (i.e., PSNR) between the up-sampled and original images. The paper describes the concept, constituent functionalities and real-time implementation enabling 8K/4K simultaneous services. |
