Abstract: Fully scalable encoder and decoder for interlaced video. A method for encoding an interlaced sequence of digital video data decomposes the interlaced video sequence into first and second fields, performs digital filtering to get lower frequency and higher frequency component signals of the first fields, and uses spatio-temporal filtering and motion estimation for generating base layer signals being suitable for reconstruction of a progressive mode video sequence in a receiver. Advantageously, both the spatio-temporal filter at the encoder, and the inverse process at the receiver, can perform scaling in spatial and temporal dimension. The second fields are used to generate enhancement signals, which enable a receiver to reproduce an interlaced video sequence of the full, or scaled, spatial and/or temporal resolution.

Abstract: In video encoding, the video frames are spatio-temporally filtered for reduction of spatial and temporal redundancy before they are entropy encoded. Known filtering schemes consider temporally successive frames and are static. It is probable but not necessary that successive frames are most efficient to encode. Therefore, a plurality or all possible frame order permutations are considered for a group of frames (GOP) and evaluated based on a global criterion, which is the sum of local criterion values computed over successive subsets of permuted frames. The local criterion value is deduced from motion estimation processed on each considered set of frames. The best ordering is chosen as the one that minimizes the global criterion value.
