Abstract:
PURPOSE: A method for converting adaptively visual contents in order to meet the color vision of a terminal user and a system for the same are provided to offer meaning information of visual contents corresponding to general users to a user having a color vision trouble without a separate device. CONSTITUTION: A user inputs one's own color vision characteristic information and environmental information to a processing member(102) through an input device(103) such as a keyboard. The processing member stores the color vision characteristic information to a database(104) with a previously determined format named by a color vision characteristic descriptor(114), so that an adaptive converting system(100) is initialized. Visual contents are provided to the processing member from an external network(107) through a network interface such as a modem. The processing member discriminates whether the user is a color-blind person or a color weakness person with reference to the color vision characteristic descriptor. When the user is a color-blind person, the processing member drives a color blind adaptive converting member(110), so that visual contents are converted adaptively by using the color vision characteristic information and environmental information and displayed to a video display device(108) such as an LCD(Liquid Crystal Display). When the user is a color weakness person, the processing member drives a color weakness adaptive converting member(112), so that visual contents are converted adaptively by using the color vision characteristic information and environmental information and displayed to the video display device(108) such as an LCD(Liquid Crystal Display).

PURPOSE: A multimedia contents offering method capable of replacing media and a device thereof are provided to diversely use the multimedia contents through a process to replace video, audio, or text media with other media depending on a trouble or a mistake during a multimedia contents service. CONSTITUTION: The device includes a contents providing server(21) storing the raw multimedia contents and a user adaptation server(22) generating/transmitting the replacement media(24) to a user terminal(23). The user adaptation server includes a storing part(31), a processing part(32), and a generating part(33). The processing part stores the information inputted from the contents providing server in the storing part while controlling the setting of a down/upstream channel between the user adaptation server and the user terminal. The processing part converts the raw contents into the user-adapted contents fit to a user characteristic and orders the generating part to generate the replacement media fit to the trouble if the trouble is existed in a function to use the multimedia contents.

PURPOSE: A device and a method for adapting audio signals to user's features are provided to adapt audio contents to a user environment by using information previously describing a use environment of a user terminal consuming the audio contents. CONSTITUTION: An audio data source tool(101) receives audio data generated from a multimedia source. An audio adaptation tool(103) receives the audio data from the audio data source tool. An audio use environment information managing tool(107) adapts the audio data to the user environment by using the information previously describing the use environment, and previously describes/manages the use environment information by collecting the information from a user, the user terminal, and an environment. An audio data output tool(105) outputs the audio data adapted by the audio adaptation tool.

CONSTITUTION: RAUs(Remote Antenna Units)(200_1-200_3) transmit communication data received from a terminal(100), or transmit the communication data to the terminal(100) by communication power received from a central unit(300). The central unit(300) controls to receive the communication data by variable power in the RAUs(200_1-200_3) based on transmission delay received from the RAUs(200_1-200_3). Each of the RAUs(200_1-200_3) consists of transmission delay elements(210) and receiving transmission delay elements(220). The transmission delay elements(210) calculate transmission delay conditions of the central unit(300), and transmit the conditions. The receiving transmission delay elements(220) receive transmission delay data received from the central unit(300).
