Spatio-Temporal Scalable Coding of Interlaced Video Sequences

In this paper we present a spatio-temporal scalable coding scheme for interlaced video sequences. 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. The scalable coding scheme proposed in this paper employs frame subsampling associated with adaptive interpolation for temporal scalability. It also employs adaptive infield/inframe DCT for spatial scalability. This scheme can be applied to interlaced video sequences effectively and it provides four different spatio-temporal resolutions of a video sequence — two temporal resolutions, each consisting of two spatial resolutions. Computer simulation experimental results have demonstrated that this scheme shows better coding performance, especially for reconstructed low resolution pictures, compared to conventional non adaptive schemes.
