The invention relates to methods and apparatuses for encoding/decoding high resolution images, which involve setting the size of the prediction unit to be encoded to an expanded macro-block size in accordance with the temporal frequency characteristics or spatial frequency characteristics among pictures to be encoded, and performing motion prediction motion compensation, and transformation on the basis of a set prediction unit size. In addition, the methods and the apparatuses of the present invention involve dividing a macro-block having a pixel size of 32*32 or 64*64 into at least one partition on the basis of an edge, and performing encoding processes for each partition. Accordingly, encoding efficiency can be improved for high definition (HD) or higher resolution high-resolution images.

A cathode ray tube includes a color selection apparatus mounted between a phosphor screen and an electron gun, and support members for supporting the color selection apparatus. Each of the support members is formed by a spring including a fixed section secured to the color selection apparatus, a locking section connected to the cathode ray tube, and a center section formed between these elements. The fixed section and the center section are separated by and bent at a first folding trace, and the center section and the locking section are separated by and bent at a second folding trace. Also, if a direction along a width of the springs is X, the first folding trace has an angle θ1 with a straight line drawn on the fixed section along direction X, and the second folding trace has an angle θ2 with a straight line drawn on the center section along direction X, the angle θ2 is greater than the angle θ1.

Motion vector for input coding unit is generated, motion compensation is performed on the basis of generated motion vector to generate prediction signal, weight parameter is generated on prediction unit basis, weight parameter is applied to the prediction signal to generate prediction macro block, and residue value is generated on the basis of received coding unit and the prediction block. The same motion parameter is allocated to the merged blocks, and the blocks are transmitted to decoder. Image encoding/decoding method selects interpolating filters to be used in inter-frame prediction based on motion compensation, for units more precise than picture unit, wherein said more precise units include at least one of slice unit and partition unit, and calculates sub-pixel values. According to present invention, quality of encoded image can be improved, and efficiency of encoding high resolution images having resolution higher than high definition (HD) class can be improved.

A method for encoding/decoding high-resolution image and a device for performing the same set the size of an extended macro-block as the size of a prediction unit to be encoded, according to a temporal frequency feature or a spatial frequency feature found therebetween at least one picture to be encoded, perform motion prediction and motion compensation using the set prediction unit size unit, and perform the conversion thereof. Also, a macro-block having 32×32 pixel or 64×64 pixel size is divided into at least one partition based on an edge, and encoding is performed on each of the divided partitions afterwards. Therefore, encoding efficiency for high definition (HD) or higher resolution images is enhanced.
