For encoding and decoding images, an image encoding device divides each picture into sub-pictures that can be independently displayed, and signals layout information about the sub-pictures, and an image decoding device identifies each sub-block through the layout information and decodes the sub-pictures. A video decoding apparatus and method are configured to decode a bitstream containing an encoded sequence of pictures which are partitioned into a plurality of subpictures including a plurality of coding tree blocks.

Video encoding and decoding method and device

A video coding method and an apparatus using a deblocking filtering based on segmentation information are disclosed. The video coding method and the apparatus perform deblocking filtering using segmentation information of an image to avoid performing filtering at the boundary of an object within the image.

Method and apparatus for video coding using de-blocking filtering based on segmentation information

A video decoding method for decoding a target block using intra prediction comprises decoding, from a bitstream, boundary line information specifying at least one boundary line for partitioning the target block. The boundary line information allows partitioning the target block into a plurality of non-rectangular blocks. The method further comprises determining intra prediction modes for the non-rectangular blocks based on the boundary line information; generating a prediction block of the target block by performing intra prediction on each of the non-rectangular blocks using the intra prediction modes; reconstructing a residual block of the target block from the bitstream; and reconstructing the target block by adding the prediction block and the residual block.

Video encoding and decoding using arbitrary block partitioning

A method is configured to process a bitstream generated by encoding a sequence of pictures partitioned into a plurality of subpictures. The method includes steps of: decoding, from the bitstream, partitioning information indicating a partitioning structure in which the pictures belonging to the sequence are partitioned into the subpictures; decoding ID information for the subpictures and mapping an ID to each of the subpictures by using the ID information; and reconstructing blocks within at least one subpicture by using the mapped ID.

Method and apparatus for encoding and decoding video using sub-picture partitioning

Disclosed are a method and an apparatus for generating quantization parameters for generating a predicted quantization parameter for a quantization group using quantization parameters of a frame encoded/decoded previously in time. The method and the apparatus may achieve an effect of improving prediction performance for the quantization parameter.

Method for predicting quantization parameter used in a video encoding/decoding apparatus

A method is provided for decoding a sequence of pictures using a gradual refresh technique. In particular, all areas in one picture are gradually encoded or decoded over a plurality of pictures associated with the picture.

Method and device for encoding and decoding image involving gradual refresh technique

The present invention relates to a touch screen device having a braille support function and a control method therefor, the touch screen device including: a touch screen sensing a touch location of a user; and a controller entering at least one of a first mode and a second mode according to a use direction of the touch screen, the controller recognizing the touch screen as one braille cell in the first mode, and recognizing the touch screen as two braille cells in the second mode, thereby receiving braille input depending on the touch location of the user. By using this, it is possible to easily and precisely input six-dot braille on a touch screen and to input abbreviations and symbols of a twelve-dot system.
