Abstract: A portable multimedia device capable of remotely controlling and receiving TV signals transmitted from a display device using a wireless transmission function thereof is disclosed. The portable multimedia device includes of: a transmission interface, a display unit, a page-dividing unit and a selecting unit. The page-dividing unit allows the user to set the number of the desired channels for preview, and further divides the picture shown on the display unit into a plurality of sub-pictures. The selecting unit allows the user to select the desired channels according to the plurality of sub-pictures, and further displays the desired channels on the display device or the display unit, thereby providing at least two different channels thereon for users' preview and view as desired.

Abstract: The invention provides a real-image navigation apparatus capable of being mounted on a vehicle having transparent equipment (windows) installed therein, including an image-capturing unit adapted to instantly capture images of a road in front of a vehicle; a satellite navigation system adapted to navigate and generate navigation routes and driver-assisting navigation information; a comparing unit adapted to compare and determine the consistency between obtained images captured by the image-capturing unit and road parameters of mapping information pre-stored in the system, and further output three-dimensional navigation routes planned by cooperating with the system; and a see-through display unit mounted on transparent equipment installed within the vehicle to display real-time driver-assisting navigation information and 3-D navigation routes outputted by the comparing unit to the user/driver, thereby presenting useful navigation data and related geographical information without overly diverting eye focus or ob
