Abstract: The invention relates to method for determining predictor blocks of a first resolution layer image from blocks of a second resolution layer image of a spatially scalable video codec, wherein a resolution of the first resolution layer image is higher than a resolution of the second resolution layer image, the method comprising: up-scaling each block of the second resolution layer image to a corresponding block of an up-scaled second resolution layer image; and filtering each block of the up-scaled second resolution layer image by a sharpening filter to obtain a predictor block of the first resolution layer image.

Abstract: Video data encoding and decoding methods and apparatuses which include determining a to-be-encoded information group in a to-be-encoded video sequence, generating a primary information group corresponding to the to-be-encoded information group, wherein the primary information group comprises a first data information, indication information that indicates whether the to-be-encoded information group is the primary information group or a redundant information group, and location information of the primary information group, generating the redundant information group corresponding to the to-be-encoded information group, wherein the redundant information group comprises a second data information, location information of the redundant information group, indication information that indicates whether the to-be-encoded information group is the primary information group or the redundant information group, and location relationship information of the redundant information group and the primary information group, and encoding the primary information group and the redundant information group into a bitstream.
