摘要： The present invention relates to a 3DTV service providing method based on declarative content and a device thereof. The 3DTV service providing method comprises the following steps: receiving 3DTV content containing declarative content; setting a stereo view volume for arranging multimedia factors of the declarative content in a 3D space based on information on stereoscopic structure included in the declarative content; dividing the multimedia factors of the declarative content according to factor or meaning; producing a scene after arranging the divided multimedia factors in the stereo view volume; acquiring a left eye image and a right eye image for the scene based on the virtual left eye and right eye cameras inside of the stereo view volume; and providing a stereoscopic 3DTV service for a user by stereoscopic-rendering the left eye and right eye images. The declarative content includes at least one among the information comprising stereoscopic structure such as the view point information, view volume setting information, or disparity information.
