A method and apparatus capable of managing the rights of multi-layered video bitstreams by layers are provided. The method includes generating a scalable bitstream from an input video, the scalable bitstream having a plurality of layers of data; generating encryption keys, each encryption key corresponding to a respective one of the layers; and generating an encrypted scalable bitstream by encrypting each layer of data by means of the encryption key corresponding to the layer. The apparatus includes a scalable video encoder which generates a scalable bitstream by using an input video, the scalable bitstream having a plurality of layer data; a license generating unit which generates encryption keys, each of the encryption keys corresponding to a respective one of the plurality of layers; and an encrypting unit which generates an encrypted scalable bitstream by encrypting the layer data corresponding to the respective encryption keys using the corresponding encryption keys.
