A novel scalable video coding scheme using super resolution techniques

A novel scheme of scalable video coding (SVC) using super-resolution techniques is proposed in this paper. Utilizing the spatial/temporal scalability of H.264/AVC, we encode half of input high-resolution(HR) frames and their low-resolution (LR) counterparts in a video sequence and employ super-resolution (SR) method to reconstruct skipped frames during decoding. The payload saved from skipped frames can be used to improve the quality of encoded frames. This scheme provides a choice of SVC to improve the quality of HR frames while maintaining low bit rate transmission and reducing encoding complexity. Experiments show that our scheme performs well in both peak signal to noise ratio (PSNR) and subjective visual quality at low bit rate.
