Abstract: The present invention relates to a method for making 3D stereo digital broadcast service compatible in an MPEG-2-TS format which is used for transmitting and receiving digital TV. To this end, suggested is a method for transmitting detailed information which supports both TS-level multiplexing and ES-level multiplexing when left and right compressed bitstreams are multiplexed, when service compatibility is enabled.

Abstract: A method for separating audio sources and an audio system using the same are provided. The method introduces the concept of a residual signal to separate a mixed audio signal into audio sources, and separates an audio signal corresponding to at least two of the audio sources as a residual signal and processes the audio signal separately. Therefore, audio separation performance can be improved. In addition, the method re-separates a separated residual signal and adds the separated residual signals to corresponding audio sources. Therefore, audio sources can be separated more safely.

Abstract: The present invention relates to a method for selecting an appropriate mode when performing a new broadcast, such as a 3D stereo broadcast, a UHDTV broadcast, and a multi-view broadcast, among others, while maintaining compatibility with existing broadcasting channels in an MPEG-2-TS format for transmitting and receiving digital TV, and to a method for recognizing a descriptor. To this end, the present invention suggests providing the descriptor which is related to synthesizing left and right images using the type of stream, existence of the descriptor, and a frame-compatible mode flag.

Abstract: A method for eliminating hologram DC noise and a hologram device using the same are provided. The method for processing the hologram includes: receiving input of hologram data; and implementing a differential operation with respect to the hologram data. Accordingly, the hologram data is processed by implementing the differential operation with respect to the hologram data, so that DC noise occurring when the hologram is reconstructed can be effectively eliminated.
