Provided is a parallax minimization stitching method and apparatus using control points in an overlapping region. A parallax minimization stitching method may include defining a plurality of control points in an overlapping region of a first image and a second image received from a plurality of cameras, performing a first geometric correction by applying a homography to the control points, defining a plurality of patches based on the control points, and performing a second geometric correction by mapping the patches.

Parallax minimization stitching method and apparatus using control points in overlapping region

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

An apparatus for encrypting and recording a broadcasting program includes a packet input unit configured to receive packets of a broadcasting program to be recorded and sequentially output the packets, an encryption selector configured to receive the packets sequentially output from the packet input unit, selectively output the received packets to a first path and to a second path, wherein packets to be encrypted are output to the first path and packets not to be encrypted are output to the second path, an encryption processor configured to encrypt the packets output to the first path based on a predetermined encryption method, and a storing unit configured to store the encrypted packets from the encryption processor or store the packets output to the second path.

Apparatus and method for recording partial encryption of broadcast program

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

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.
