Abstract: A method for controlling electronic device includes the following blocks. A control signal is received from an earphone jack. A predefined control command corresponding to the control signal is obtained. At least one application associated with the predefined control command is determined whether is initialized. The predefined control command is executed when the at least one application is initialized.

Abstract: Disclosed is a system and method for editing video data through marking during video playing so that image retrieval and compiling can be easily made afterwards. During playing the video, the user commands at any position. The system gets the corresponding playing time and stores it as a mark. Then, in the editing operation, the system rapidly and precisely fetches the corresponding video clip according to the mark for replay and compiling so as to save time and improve efficiency.

Abstract: A backlight controlled closeup photographing system is proposed, which is designed for use with a multimedia-capable information platform, such as an MMV (MultiMedia Viewer) device, to allow the user to photograph a small object, such as a business card, at close range with intensified illumination on the object for the purpose of allowing the photographed digital image to have adequate brightness in picture quality. The proposed backlight controlled closeup photographing system is characterized by the use of backlight control to increase the intensity of the backlight illumination on the object being photographed for the purpose of allowing the photographed digital image to have adequate brightness in picture quality. Since the intensity of illumination on the object can be increased without using flash unit, the invention is apparently more cost-effective and advantageous to use than prior art.

Abstract: A multifunctional integrated multimedia viewer system is proposed, which is characterized by the integration of an assortment of media processing functions, including a digital photo browsing function, an audio playback function, a video playback function, a video/audio recording function, an earth location identifying function, and a TV display function, all in one single device unit, so that the user can enjoy these media processing functions all from one single device unit without having to purchase a number of devices. Moreover, the proposed multimedia viewer system also provides an assortment of interfaces, including a wireless interface, an AV I/O interface, a USB interface, and an external storage interface, which allow the user to further expand the media processing functionality.
