    • 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.

    • 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.
    • 命令输入法利用惯性系统体现的三维运动识别装置,特别涉及使用运动识别装置的初始姿态信息以及运动模式来扩展可输入命令的总数。 命令输入方法包括以下步骤:当生成运动识别装置的移动时,确定起始点处的初始姿势; 确定运动结束时运动的模式; 以及从确定的初始姿势和运动模式确定命令。 由于可以通过输入装置的初始姿态将三维空间运动进一步区分成不同的命令,所以能够以较少的识别运动的结构简化命令输入系统。
