A water ring encoding apparatus configured to process an initial data set, such as a video image frame, is disclosed. The water ring encoding apparatus includes a a scanner and an encoder. The initial data set is organized with at least one initial origin enveloped by a plurality of nested initial environs successively surrounding each other in the initial data set. The scanner is configured to write a portion of the data from the initial data set into a scanned data string by starting at the RC grouping corresponding to the initial origin (initial water ring (0)) and by sequentially progressing outwardly from the family of RC groupings corresponding to the nearest nested initial environ (initial water ring (1)) towards the family of RC groupings corresponding to a furthest nested initial environ (initial water ring (n)). The encoder is configured to encode the scanned data string into an encoded data string.

An apparatus for coding an image is provided to effectively code the image. The apparatus for coding the image includes an input image segmentation unit to segment an input image into a plurality of image blocks including a first image block and a second image block. The apparatus also includes a waveform information generation unit to select a plurality of reference pixels from among pixels included in the first image block, generate first waveform information about the first image block based on a pixel value difference between the selected plurality of reference pixels, and generate second waveform information about the second image block based on a pixel value difference between the pixels included in the second image block. The apparatus also includes a coding unit to code an image included in the second image block based on the first waveform information and the second waveform information.

Disclosed are a signaling method for a stereoscopic video service and an apparatus using the method. An image decoding method comprises: a step of determining a field value based on a broadcast service type and a display mode in decoding a program level descriptor; and a step of determining an encoded stream type, whether an elementary stream is a reference stream, whether the elementary stream is a left-eye image or a right-eye image, additional image upsampling information and information on a subsampled line. Thus, efficiency of encoding/decoding an additional image for a stereoscopic video content may increase.

Disclosed is a broadcasting signal receiving apparatus for controlling use of a broadcasting program using a signature in program information and a method thereof. The broadcasting signal receiving apparatus includes a communicating unit for receiving a broadcasting signal, an extracting unit for extracting a broadcasting program and program information from the received broadcasting signal, and a determining unit configured to generate a temporal signature for confirmation (confirmation signature) which determines whether the program information is changed or not from the original program information and determine validity of the program information by comparing a signature included in the extracted program information with the confirmation signature.

In accordance with an illustrative configuration, a device and a method are configured to receive video stream including a stream receiving unit, a demultiplexing unit, and a decoding unit. The stream receiving unit is configured to receive multiplexed stream of video stream and signaling information describing the video stream. The demultiplexing unit is configured to demultiplex the received stream to video stream and signaling information. The decoding unit is configured to decode the demultiplexed video stream by using the signaling information. The signaling information includes stream type information on the video stream providing stereoscopic service and service type information, which indicates whether the service type according to the video stream is 2D monoscopic service or 3D stereoscopic service.

A water ring encoding method of processing an initial data set, such as an image frame, is disclosed having a writing step and an encoding step. The initial data set is organized with at least one initial origin enveloped by a plurality of nested initial environs successively surrounding each other in the initial data set. The writing step includes writing a portion of data from the initial data set into a scanned data string, by starting the writing of the portion of the data from the initial data set into the scanned data string at the RC grouping corresponding to the initial origin (initial water ring (0)) and by sequentially progressing the writing outwardly from the family of RC groupings corresponding to the nearest nested initial environ (initial water ring (1)) towards the family of RC groupings corresponding to a furthest nested initial environ (initial water ring (n)). The encoding step includes encoding the scanned data string into an encoded data string.

A water ring decoding apparatus configured to process a data string into a restored data set, such as a video image frame, is disclosed. The restored data set is organized with at least one restored origin enveloped by a plurality of nested restored environs successively surrounding each other in the restored data set. The decoder is configured to write the data string into the restored data set by starting at the RC group corresponding to the restored origin (restored water ring (0)) and by sequentially progressing outwardly from the family of RC groups corresponding to the nearest nested restored environ (restored water ring (1)) towards the family of RC groups corresponding to a furthest nested restored environ (restored water ring (n)).

There are provided a 3-D image synchronization method and apparatus. The method comprises determining a reference region for each of the frames of a first image and determining a counter region for each of the frames of a second image, corresponding to the reference region, for the first image and the second image forming a 3-D image; calculating the feature values of the reference region and the counter region; extracting a frame difference between the first image and the second image based on the feature values; and moving any one of the first image and the second image in the time domain based on the extracted frame difference.

Disclosed is an apparatus and method for transmitting/receiving reference image data and 3D additional image data in 3D image data so as to provide a 3D image in a digital broadcasting system. In the method, a basic image and a 3D additional image in a 3D image of a 3D broadcasting service is processed in a stereoscopic image format of one of a side-by-side method and a top-down method. The basic image and the 3D additional image processed in the stereoscopic image format are encoded to a basic image stream and a 3D additional image stream. The encoded basic image stream and the encoded 3D additional image stream are multiplexed to a 3D image stream of a single stream using a dual stream method, and the multiplexed 3D image stream is then transmitted.
