A method and apparatus for scalable video and decoding are provided. A method for video coding includes eliminating temporal redundancy in constrained temporal level sequence from a plurality of frames constituting a video sequence input, and generating a bit-stream by quantizing transformation coefficients obtained from the frames whose temporal redundancy has been eliminated. A video encoder for performing the encoding method includes a temporal transformation unit (10), a spatial transformation unit (20), a quantization unit (30), and a bit-stream generation unit (40). A video decoding method is in principle performed inversely to the video coding sequence, wherein decoding is performed by extracting information on encoded frames by receiving bit-streams input and interpreting them. |
