Disclosed herein is a non real-time broadcast receiving system. The system includes: a non real-time service decoder dividing received non real-time service content into a transmission block according to a protocol; a service content manager monitoring whether the receive of the non real-time service content stops and acknowledging a schedule regarding whether a portion with errors in the non real-time service content is retransmitted; a memory storing a portion without errors in the non real-time service content; a file checker checking whether errors are produced during the receive of the non real-time service contents and determining whether the portion with errors in the non real-time service content is retransmitted; a retransmission request signal generator generating a retransmission request signal; a return channel transmitter transmitting the retransmission request signal; and a return channel receiver receiving data corresponding the portion with error.

Provided is a method and apparatus for encoding and decoding multi-view video data. The encoding method includes: decomposing each view image of the multi-view video into an overlapped region and a non-overlapped region, the overlapped region being overlapped with other view image and the non-overlapped region not being overlapped with other view image; generating a stitched image by combining the non-overlapped region of each view image and a middle view image; encoding the stitched image using a first encoding algorithm; and encoding the overlapped region of each view image, using a second encoding algorithm. Further, the decomposing step includes the steps of estimating disparity information for each view image, based on a predetermined view image; and decomposing each view image into said overlapped region and said non-overlapped region using the estimated disparity information.

A method and apparatus for providing 3D still image service in a specific time interval during audio-visual service of digital broadcast are provided. The method includes receiving a reference image and a 3D supplement image, which construct a 3D still image, through a data channel or a video channel together with a 2D image; restoring the reference image and the 3D supplement image to the 3D still image; and displaying the 3D still image in a specific interval during digital audio-visual broadcast using the 2D image according to display information which includes a play time and a play mode.

According to the present invention, a transmission apparatus and method and a reception method and apparatus for providing a 3D service are disclosed. The transmission method for providing the 3D service while making a reference image transmitted in real-time interwork with an additional image transmitted separately from the reference image includes a real-time reference image stream generating step of generating a real-time reference image stream based on the reference image and transmitting the generated real-time reference image stream to a receiving side in real-time and an additional image transmitting step of transmitting the additional image providing the 3D service in interworking with the reference image to the receiving side separately from the reference image stream, wherein the real-time reference image stream includes a linkage information, which is information relating to the additional image to be interworking with the reference image and synchronization information for synchronization with the reference image and the additional image and content.

Provided are an apparatus and method of transmitting and receiving associated broadcasting contents based on a heterogeneous network. The transmission system generates a basic contents stream for basic contents configuring the broadcasting contents to transmit the basic contents stream to a terminal through a broadcasting network, generates an additional contents stream for additional contents associated with the basic contents to transmit the additional contents stream to the terminal through a communication network, and further transmits at least one of associated playing information on the basic contents and associated playing information on the additional contents to the terminal, and the reception terminal receives the basic contents stream, the additional contents stream, and the associated playing information and synchronize the basic contents and the additional contents with each other to play them, thereby playing the broadcasting contents in real time.
