The present invention provides a method of providing online information using image, including separating each of a target image, received from a user terminal, and an original image, received from an information provider apparatus, into a text region and a graphic region; selecting an important text region from the text region; extracting features from the text region, the graphic region, and the important text region, respectively; searching for the original image corresponding to the target image using the features of the text region, the graphic region, and the important text region; and searching for supplementary information related to the retrieved original image and provided the retrieved supplementary information.

A command input method makes use of a three-dimensional motion recognition device embodied with an inertia system and is particularly directed to extend the total number of inputable commands using initial posture information as well as movement pattern of a motion recognition device. The command input method includes the steps of: determining initial posture at start point when movement of the motion recognition device is generated; determining a pattern of the movement at the end of the movement; and deciding a command from the determined initial posture and the movement pattern. Since the three-dimensional spatial motion can be further differentiated into different commands by the initial posture of the input device, the command input system can be simplified in structure with less number of recognizable motions.

Provided are an IPTV service system and a method thereof. The IPTV service system includes: a headend, a set-top box, and a plurality of multicast routers. The headend assigns a multicast group address for each channel and assigns a source address for each PID with respect to an MPEG-TS and packetizes the MPEG-TS into a plurality of packet streams. The set-top box identifies a user-selected channel and the necessary elementary streams in the MPEG-TS for the selected channel, and requests selective reception of only packet streams corresponding to the selected channel and the necessary elementary streams from the plurality of packet streams. The plurality of multicast routers form a multicast path between the headend and the set-top box. Accordingly, while services such as a multi-angle service, a multi-lingual service, a mosaic EPG service, and a personalized EPG service are realized in one multicast control method together with viewing of a general broadcasting channel, efficient use of bandwidth can be achieved.

Provided are an apparatus and method for character recognition that analyze three-dimensional motion of a user using an acceleration sensor and thereby perform character input and character recognition. The apparatus and method easily discern each stroke on the basis of a direction of motion at the beginning portion and end portion of the stroke, and recognize a character using a combination of the strokes, thereby enabling realization of a small-sized motion-based character input system.
