A prediction mode determining method in scalable video coding based on a structure of multiple layers is provided. The prediction mode determining method includes: deriving a coded block pattern (CBP) value of a luma component for a 16×16 mode of an encoding target picture; determining first candidate modes for the encoding target picture according to the derived CPB value; and determining a final prediction mode for the encoding target picture based on the determined first candidate modes. According to the present invention, encoding efficiency may be improved, and complexity may be reduced.

Disclosed are an apparatus and a method related with a user interface that allows a user to easily use services provided by equipment when output images of video equipment are projected onto an external screen by a projector. According to exemplary embodiments of the present invention, a human body may be used as a pointer to form a shadow, and the shadow may be analyzed to control the projection image. Therefore, the projection image can be controlled without using an interface device, which can provide an easy and intuitive user interface to a user.

A scalable video decoder and a controlling method thereof are provided. A method of controlling a scalable video decoder includes: determining whether a macro block mode of an upper layer is an interlayer prediction mode when decoding a scalable video; when the macro block mode of the upper layer is determined as the interlayer prediction mode, determining an up-sampling operation is required to thereby either perform texture up-sampling using corresponding macro block information of a lower layer and neighboring pixel information, or perform residual up-sampling using the corresponding macro block information of the lower layer; and decoding the upper layer using the texture up-sampling or the residual up-sampling.
