    摘要： Provided is an object description and multiplexing method which provides an object descriptor of a new structure and a multiplexing method for a 3D still image service based on DMB, such as 3D still image advertisement service, and provides 3D a user with still image service through interaction with the user at a specific time or specific video scene while maintaining compatibility with conventional DMB services, and a decoding apparatus and method using the object description and multiplexing method. The method for describing an object to provide a 3D still image service based on DMB, which includes: deciding a broadcasting type of a still image service to be broadcasted between two-dimensional broadcasting and 3D broadcasting based on a program information descriptor in a program map table; and describing reference still image and additional still image that are transmitted separately for the 3D still image service with relation to each other.

    摘要： Provided are an apparatus and method for coding and decoding a multi object audio signal with multi channel. The apparatus includes: a multi channel encoding means for down-mixing an audio signal including a plurality of channels, generating a spatial cue for the audio signal including the plurality of channels, and generating first rendering information including the generated spatial cue; and a multi object encoding unit for down-mixing an audio signal including a plurality of objects, which includes the down-mixed signal from the multi channel encoding unit, generating a spatial cue for the audio signal including the plurality of objects, and generating second rendering information including the generated spatial cue, wherein the multichannel encoding unit generates a spatial cue for the audio signal including the plurality of objects regardless of a Coder-DECoder (CODEC) scheme the limits the multi channel encoding unit.

    摘要： Provided is a method for controlling synchronizing downmix signals and MPEG surround side information signals by controlling a delay according to the kind of downmix audio signals in an MPEG surround decoder. When multi-channel audio signals are restored using an HE-AAC decoder and a low-power MPEG surround decoder and complex QMF signals outputted from the HE-AAC decoder are used as downmix signals, a delay unit compensates for a delay caused in a real-to-complex converter. Anther delay unit delays spatial parameters to compensate for a delay caused in QMF and Nyquist banks when time-domain downmix signals are used. Also, when multi-channel audio signals are restored using an HE-AAC decoder and a high-quality MPEG surround decoder and complex QMF signals outputted from the HE-AAC decoder are used as downmix signals, a delay unit compensates for a delay caused in a real-to-complex converter.
