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 describes a spatio-temporal scalable video coding scheme which employs adaptive field/frame subsampling with adaptive interpolation for temporal scalability and adaptive infield/inframe subband coding for spatial scalability. The proposed scheme can be applied to interlaced video sequences effectively, providing four different spatio-temporal resolutions of an input video sequence. Computer simulation experimental results have shown that this scheme has higher coding performance compared to conventional non adaptive schemes
