Abstract:
A method of controlling a power supply of a digital TV with a function of executing applications is provided. According to the method, in a digital TV apparatus with the application executing function, a power supply of a general-purpose CPU platform which processes data required for executing an application and a power supply of a decoding unit which decodes digital broadcasting data and outputs the decoded data on a screen are controlled separately.
Abstract:
A method and apparatus for overlaying broadcast video with application graphics in a digital TV having an application-execution function are provided. The apparatus includes a decoding unit which decodes a received digital broadcast signal and outputs a video signal, a memory unit which stores graphic data used for the application, and an embedded central processing unit (CPU) comprising a video processor which overlays the video signal directly received through a dedicated input port from the decoding unit with the graphic data stored in the memory unit, so that the overlaid result makes one screen.
Abstract:
An apparatus, system, and method for transmitting content in a home network is provided in which predetermined content is recorded according to preprogrammed recording information set by a user. The content is transcoded and encrypted using a content storage device and then encrypted and transmitted to a user selected mobile device. The apparatus includes a receiving unit, a recording setting unit, a transcoding unit, an encrypting/authenticating unit, and a control unit. The receiving unit receives content. The recording setting unit allows a user to set preprogrammed recording information and then records the received content according to the information. The transcoding unit transcodes the recorded content. The encrypting/authenticating unit encrypts the transcoded content and performs authentication with respect to the predetermined mobile device. The control unit controls the received content, the recorded content to be transcoded, and checks the predetermined mobile device selected when the user sets preprogrammed recording.

Abstract:
A digital TV equipped with a general-purpose CPU having a higher performance than that of an embedded CPU and a signal processing method thereof are provided. According to the digital TV and method, if the digital TV is turned on, digital broadcast data is received and decoded irrespective of whether or not system booting is completed, and while the system booting is performed, the decoded signal is made to be output to a display apparatus. Accordingly, after the digital TV is turned on, a user does not need to wait until the system booting is completed and can watch the digital broadcasting while the booting process is being performed.

Abstract:
A method for generating image data includes adjusting an angle formed by each of a plurality of lenses attached to the imaging device relative to a reference plane based on a photography mode, obtaining at least one first image data using the plurality of adjusted lenses, and generating second image data corresponding to the photography mode using the at least one first image data.
Abstract:
Provided is an apparatus and method for obtaining a high dynamic range (HDR) image. The apparatus includes an image sensor generating a first image by applying different exposure times for units of different predetermined regions, an image separating unit separating the first image into images, each of which is composed of regions having an identical exposure time, an image restoring unit restoring the separated images in such a way that each of the separated images has a resolution that is the same as a resolution of the first image, and an image synthesizing unit synthesizing the restored images into a second image.
Abstract:
A method of and an apparatus for copying and decrypting encrypted digital data. The method of copying encrypted digital data includes encrypting a first media key block to be used for decryption of the encrypted digital data using a predetermined key of a second information storage medium and storing the encrypted digital data and the encrypted first media key block in the second information storage medium. Security of data encryption is heightened by not discarding an encryption key used for an initial encryption, encrypting the encryption key used for initial encryption using another encryption key used for a second encryption, and storing the encrypted encryption key with the data. Also, since unnecessary decryption and encryption of data are not repeated, the time required for copying data is reduced, and since data is transferred between apparatuses in an encrypted state, a security level is higher.
Abstract:
A method of providing a photo development service in a digital TV and an apparatus therefor are provided. The method includes, automatically displaying part or all of the photo images on the screen if an external storage medium storing photo images is connected to a digital TV, and transmitting an image selected by a user from among the displayed images to a website providing a photo development service and requesting development of the image.
