Abstract
Resolution scalability refers to a picture coding property where pictures at lower different resolutions can be reconstructed by decoding only the subsets of a single coded bit-stream, while the full resolution picture is reconstructed by decoding the total bit-stream. This paper presents a resolution scalable video coding scheme for interlaced video sequences. The proposed scalable coding scheme employs adaptive in-field/in-frame subband for spatial scalability, where in-field subband and in-frame subband are adaptively used for moving portions and stationary portions respectively. It also employs adaptive field/frame subsampling for temporal scalability. Experimental results have demonstrated that the proposed adaptive subband gives better picture quality especially for reconstructed lower resolution pictures compared to non adaptive subband.
