Appartus and method for scalable video coding providing scalability in encoder part

The invention relates to a method and apparatus for implementing scalability (scalability) in the process of the temporal filtering (temporal filtering) of the scalable video encoding. The scalable video encoding apparatus according to the present invention may determine the order in which the temporal filtering of the frames, and one frame to the time mode to determine a predetermined time-out conditions in which the criteria for the filter will perform a selection unit, selecting the mode according to the temporal filtering order determined in part, made of a motion-compensated temporal filtering portion relative to the frame that satisfies the time condition and perform temporal filtering. According to the present invention, by implementing the encoder side scalability, it is possible to ensure a stable operation of an application that supports real-time two-way streams, such as video conferencing.
