Abstract
Official abstract text for this publication.
Provided is a video encoding apparatus, including a signal separator to separate a differential image block into a first domain and a second domain, based on a boundary line included in the differential image block, the differential image block indicating a difference between an original image and a prediction image with respect to the original image, a transform encoder to perform a transform encoding with respect to the first domain using a discrete cosine transform (DCT), a quantization unit to quantize an output of the transform encoding unit in a frequency domain, a space domain quantization unit to quantize the second domain in a space domain, and an entropy encoder to perform an entropy encoding using outputs of the quantization unit and the space domain quantization unit.
First claim
Opening claim text (preview).
The invention claimed is: 1. A video decoding apparatus, comprising: a signal separator configured to determine whether a block is a first block with a size that is not a minimum size (4×4) or a second block with a size that is a minimum size (4×4), and configured to determine whether the second block is transformed based on information indicating whether the block is not transformed, wherein the information is not signaled for the first block and is signaled for the second block;…
