摘要： An IPTV interactive system and device and an interactive method thereof are provided. The system includes a user side and a server side. The user side has a digital signal control device and includes: a user side time calibration unit; a display unit, used for playing multimedia information; an operation unit, used for outputting a control signal; and a signal receiving unit, used for receiving the control signal. The server side includes: a server side time calibration unit, used for adjusting a time of the user side to be synchronous with the server side; an application server, used for generating and displaying a widget menu page including multiple operation options; a network server, used for transferring an option of the widget menu page corresponding to the control signal to the user side; and a database, used for storing at least a piece of correlation information corresponding to the multimedia information.

摘要： A detection apparatus, a detection method and a computer readable medium thereof for detecting an object in real time are provided. The detection apparatus is electrically connected to a video capturing apparatus for capturing a video sequence comprising the object. The detection apparatus generates a first transformed frame and a second transformed frame according to the video sequence, and retrieves a plurality of target pixel bits and a plurality of adjacent pixel bits from the first transformed frame. The detection apparatus further interlaces the target pixel bits and the adjacent pixel bits to enhance the accuracy of determining the position where the object appears in the second transformed frame without considerably increasing the computational complexity.
