Abstract: A method and an apparatus for displaying LASeR(Lightweight Application Scene Representation) contents are provided to effectively display LASeR contents by configuring a LASeR DOM(Document Object Model) by using a LASeR scene API(Application Program Interface) and accessing such LASeR DOM through the LASeR scene API. A parsing unit(110) parses a LASeR XML or LASeR binary stream. A LASeR DOM converting unit(120) converts LASeR scene information of the parsed LASeR binary stream into XML(eXtensible Markup Language) type data. A LASeR DOM generating unit(130) generates a LASeR DOM based on the parsed LASeR XML or the converted XML type LASeR scene data. A display unit(140) accesses the LASeR document object model by using a LASeR API providing contents information included in LASeR data, and displays a LASeR scene.
