A method and apparatus for providing contents services. The method of using a contents service includes the operations of receiving a list of available contents services from a first server and displaying the list, transmitting, to the first server, a list of contents services selected from the displayed available contents service list, and updating service subscription data with reference to the selected contents service list. Accordingly, the subscription of contents services, such as a channel service that provides each user with different information according to subscription information, can be managed at any time and at any place without being dependent on a specific PC or a specific PC program. Even while moving without being connected with a PC, a mobile device can automatically update its contents.

Apparatus and method providing content service

A method and apparatus to process a user-defined audio user interface (UI), and an audio device using the same. The method includes designating a specific portion of an audio signal being reproduced, using a specific input member, capturing audio data of the designated specific portion, mapping the captured audio data of the designated specific portion to information on the specific input member, and constructing an audio UI database using the audio data of the designated specific portion mapped to the information on the specific input member. Accordingly, by constructing an audio UI database by selecting sounds preferred by a user, demands of various users, which cannot be provided by existing MP3 players, can be satisfied.

Method and apparatus to process an audio user interface and audio device using the same

An apparatus and method of automatically compensating audio volume in response to a channel change. The method includes generating a gain value to adjust a level of an input audio signal by comparing an average level of the input audio signal with a predetermined input/output level curve, adjusting an audio volume of the input audio signal by applying the generated gain value to the level of the input audio signal, and adjusting a dynamic range of the audio signal having the adjusted audio volume.
