Apparatus and/or method for adaptively encoding and/or decoding scalable-encoded bitstream, and recording medium including computer readable code implementing the same

摘要

An encoding and decoding method for adaptively protecting a scalable-encoded bitstream. Accordingly, it is possible to adaptively protect a scalable-encoded bitstream by selectively encrypting a bitstream for a particular layer or embedding a watermark into the bitstream. The method is applicable to various fields of application.
