Abstract
A video layered coding or decoding method in an interlaced mode, including: dividing a frame of a current layer into fields after interlacing; determining a field in the current layer at the same time point as a frame in an upper layer according to a corresponding relation on a time axis; and predicting the frame in the upper layer through the corresponding field at the same time point, so as to realize inter-layer predictive coding or decoding.
Claims16
A video layered coding or decoding method in an interlaced mode, comprising:
- dividing a frame of a current layer into fields after interlacing;
- determining a field in the current layer at the same time point as a frame in an upper layer according to a corresponding relation on a time axis;
- and
- predicting the frame in the upper layer through the corresponding field at the same time point, so as to realize inter-layer predictive coding or decoding.
