| 20100160835 | APPARATUS AND METHOD FOR DETECTING UPPER BODY POSTURE AND HAND POSTURE - Provided are an apparatus and method which detect a user's upper body posture and the user's hand postures through at least two cameras to configure a user interface such as computers and home appliances. An apparatus for detecting upper body posture and hand posture includes a stereo vision calculation unit, a color pattern categorization unit, a plurality of position detection units, an upper body posture recognition unit, and a hand posture recognition unit. The stereo vision calculation unit calculates three-dimensional distance information from each image provided from at least two cameras. The color pattern categorization unit categorizes each color and pattern from the image to output color information and pattern information. The position detection units extract three-dimensional position information for each subject based on the three-dimensional distance information, the color information and the pattern information. The upper body posture recognition unit recognizes an upper body posture based on the three-dimensional position information. The hand posture recognition unit recognizes hand postures with hand position information of the three-dimensional position information. | 06-24-2010 |

| 20100229211 | FAST CHANNEL CHANGE SYSTEM USING MULTIPLE MULTICASTS IN IPTV NETWORK AND METHOD THEREOF - Provided are a fast channel change apparatus based on multiple multicasts communication in an IPTV network, and a method thereof. In the fast channel change system, after separately generating at least one multicast stream obtained by applying different time delays respectively to original multicast stream to be broadcast, a channel server dynamically analyzes information regarding the at least one multicast stream. After querying the channel server for information regarding an optimal multicast stream and receiving the response to the query, a user terminal joins a multicast group on the optimal multicast stream through a router. After a predetermined time is elapsed, the user terminal joins a multicast group of the original multicast stream. Thus, it is possible to easily and inexpensively embody a fast channel change function network based on multiple multicasts communication in an IPTV network. | 09-09-2010 |
