Disclosed herein are a method, an apparatus and a storage medium for image encoding/decoding using a segmentation map. A feature vector for an image may be extracted using a segmentation map. The image may be encoded using the segmentation map and the feature vector. An output stream from an encoding apparatus may include a video stream and a feature stream. An input stream to a decoding apparatus may include a video stream and a feature stream. The image may be reconstructed using a reconstructed segmentation map and a reconstructed feature vector.

Method, apparatus and storage medium for image encoding/decoding using segmentation map

Disclosed herein are an apparatus and method for synthesizing virtual viewpoint image. The apparatus for synthesizing virtual viewpoint images includes one or more processors, and an execution memory for storing at least one program that is executed by the one or more processors, wherein the at least one program is configured to receive multiple viewpoint images from cameras that capture images of multiple viewpoints, and back-project the multiple viewpoint images onto a world coordinate system in a three-dimensional (3D) space, generate warped images by performing triangular warping of projecting the multiple viewpoint images, back-projected onto the world coordinate system, onto a virtual viewpoint image coordinate system, and generate a finally synthesized virtual viewpoint image by blending the warped images.

Apparatus and method for synthesizing virtual viewpoint images

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.

Apparatus for coding or decoding intra image based on line information of reference image block

Provided are an apparatus and method for controlling program conversion according to program protection information. The method for controlling conversion of a broadcasting program includes: demultiplexing a broadcasting program into broadcasting program data and program protection information; encrypting the broadcasting program data based on distribution condition of the program protection information when recordation of the broadcasting program data is requested; and recording the encrypted broadcasting program data.

Apparatus and method for controlling conversion of broadcasting program based on program protection information

A terminal for reproducing a digital content in support of transmitting/receiving the digital content to/from another terminal based on whether a terminal is registered in a domain and whether a terminal belongs to a person use scope such that the terminal belonging to the person use scope is not registered in the domain.

Digital contents reproducing terminal and method for supporting digital contents transmission/reception between terminals according to personal use scope

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.

Apparatus and method for controlling use of broadcasting program using signature in program information

Provided is a Simple Aggregation Format (SAF) synchronization packet structure including a SAF synchronization packet header and a SAF synchronization packet payload and multiplexing diverse element streams which include a scene description elementary stream. The SAF synchronization packet header includes time information related to an access unit included in the SAF synchronization packet payload, and the SAF synchronization packet payload includes header information on the access unit and payload information indicating the access unit. Since the present invention can multiplex diverse elementary streams effectively and simply into one data stream, synchronized data transmission is possible. Since the present invention accommodates a synchronization layer packet of the MPEG-4 system, it can be easily integrated with the MPEG-4 system and utilize the advantage of the MPEG-4 synchronization layer packet such as the concept of an access unit or a degradation priority.

SAF synchronization layer packet structure and server system therefor

A system for authenticating personal use of contents by using a portable storage medium includes: a portable personal use authentication device configured to store domain authentication information; and a contents personal use authentication apparatus configured to extract playback information for playing a provided content based on the domain authentication information and provide the extracted playback information to a player.

Apparatus and method for authenticating personal use of contents by using portable storage

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 ()) and by sequentially progressing the writing outwardly from the family of RC groupings corresponding to the nearest nested initial environ (initial water ring ()) 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.

Water ring encoding method

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)).
