Abstract: Provided are an apparatus and a method for selecting an adaptive layer, and a server having the same. The apparatus for selecting an adaptive layer comprises a monitoring unit for monitoring a connection state of at least one channel connected via a communication network; a channel management unit for detecting an available channel to be used to provide a service based on the monitoring results; and a layer management unit for determining the number of adaptive layers to be used for encoding based on the bandwidth of the available channel changed when the number of available channels is changed.

Abstract: PURPOSE: A directional information based fast mode decision method in scalable video coding is provided to perform real time processing a process of scalable video coding by speeding up an encoding process. CONSTITUTION: A video encoder applies a decision block according to a motion encoding result with respect to a lower layer of an inputted video frame to motion encoding of a higher layer. The video encoder decides a prediction candidate block mode of the higher layer using directional information according to the motion encoding of the higher layer and applies direction information in the neighboring blocks to a current block(440). The video encoder decides candidate block modes of the current block which uses the directional information of the neighboring blocks, calculates RDC(Rate Distortion Cost) with respect to the decided candidate blocks and decides the final encoding block mode(450,460).

A qualitative scalable coding unit (570) uses a quantization step which is a method for the qualitative scalability of the color video. A motion estimation unit uses the motion information of the base layer of the color video as the predictive data, and encodes the base layer of the depth video.
