Abstract: A mobile terminal includes a display and a controller. The display outputs a first input window configured to receive a first message. When input data is received into at least one message field of the first input window, the controller determines whether or not the input data conforms to a format of the first input window corresponding to the first message. The controller also outputs a notification after the input is determined not to conform to the format corresponding to the first input window corresponding to the first message. The display outputs a second input window to receive a second message. The second input window has at least one message field different from the message fields in the first input window.

Abstract: The present invention relates to a method of displaying several types of messages all together through a single window and of enabling a user to write and transmit a message with no consideration of message type. This unified message management method displays various types of messages all together along with their respective message types through a single window, converts the type of a written message, if needed, to match it to a protocol determined based on information written in its field distinguishing a message type, and transmits the type-converted message, whereby a user can confirm all types of received messages at a time and user's inconvenience that a message type to write should be distinguished in advance prior to choosing a message input screen can be removed.

Abstract: The present invention relates to a method of discounting a multi-media content item, which is to be sold at a purchase request through a communication network, such as the Internet. The discount is offered in proportion to the number of advertisement (ad) items chosen by a buyer to be added to the multi-media content item. With this method, a multi-media content to be sold and at least one ad content are selected individually through the communication network. The multi-media content and the ad contents are combined with each other, and the price of the combined content is discounted based on how many ad contents are added to the multi-media content. Accordingly, this method can induce increased sales of multi-media contents by discounting goods sold in connection with ads. Additionally, this method helps guarantee the effectiveness of ads by reproducing the ads together with the multi-media content whenever the multi-media content is played back.

Abstract: A method and apparatus for providing a suitable soft keyboard for end users to conveniently enter data to a portable information terminal that can not provide concurrently multiple character set keyboards, such as Korean, English, and Numeric keyboards. A data input assisting method displays an input window including a plurality of input fields when data input is requested. The input window identifies an input data set among English, Numeric, and non-English character sets suitable to an input field, which is selected for information input on the displayed input window, and provides a soft keyboard of touch screen or the like including the identified character set. Therefore, data input is ensured when a user must select and enter non-English (e.g., Korean), English, or Numeric data to match information type of each data field to be stored in a portable information terminal, such as a Personal Digital Assistant (PDA).

Abstract: Resume mark managing methods and apparatus for A/V data can define resume marks respectively representing last playback positions where playback of A/V data has been stopped. When playback of A/V data recorded on a recording medium is stopped, a resume mark separated from the other resume marks is stored to subsequently access a last playback position where the playback is stopped. When a resumed playback operation is requested for the A/V data, a selected last playback position is searched for, based on stored resume marks such as in a bookmark function, so as to play back the A/V data from the selected last playback position. Accordingly, it is possible to successively play back the A/V data from a selected one of the last playback positions.
