The present invention relates to a method and apparatus for providing a plurality of transport interactive 3DTV broadcasting services in the provision of higher definition 3D video service and 3D data service, while maintaining the compatibility with the existing digital TV broadcasts or 3DTV services. To this end, an input 3D video is encoded to generate a 3D additional video base stream and a 3D additional video enhanced stream. Engineer information for defining engineers, which includes 3D broadcasting service configuration information, is generated, and then an encoded 2D base video stream, an encoded audio stream, the encoded 3D additional video base stream and the engineer information are multiplexed and transmitted via a base layer. The 3D additional video enhanced stream is multiplexed and transmitted via an enhanced layer.
