Abstract: Digital photo albums, display methods thereof and controllers using the display methods are provided by the present invention so that a user can have a page-turning effect during switching digital photos. The first display method with the page-turning effect includes generating a plurality of digital photos with an arbitrary quadrilateral, and sequentially displaying the present digital photo, the plurality of digital photos with an arbitrary quadrilateral and the next digital photo. The second display method with the page-turning effect includes respectively dividing the digital photo and the next digital photo into a plurality of image data blocks, sequentially generating a plurality of intermediate digital photos according to the image data blocks of the present digital photo and the next digital photo and sequentially displaying the present digital photo, the intermediate digital photos and the next digital photo on a screen.

Abstract: The present invention provides a method for simultaneously playing video frames and trip message, and the method includes the following steps: (a) receiving a trip video frame data; (b) decoding the trip video frame data to obtain a plurality of video frames and a plurality of trip message, wherein each of the trip message corresponds to one of the video frames; (c) simultaneously displaying at least one video frame and its corresponding trip message. When the user uses the method for playing the trip video frame data, the user can simultaneously see the video frame and its corresponding trip message, so as to achieve a good performance of monitoring.

Abstract: A method for processing trip information and dynamic data streams are provided, and includes the following steps. (1) A dynamic data stream including a plurality of video frames is received. (2) Plural batches of trip information are received. (3) At least one batch of trip information and at least one corresponding video frame of the dynamic data stream are taken to construct trip video data. Therefore, when a user playbacks the trip video data, the user can simultaneously see the video frame and obtain the corresponding trip information thereof.

Abstract: The present invention discloses a multimedia data processing method that uses a multiplication operation unit, an exclusive-or operation unit, a bit right shift operation unit, a bit left shift operation unit and a comparison operation unit to compute a square root for an integer in a binary form, such that more computations can be processed in a shorter time, and lower the cost for a programmable digital calculator and digital circuits which comes with a central processing unit of a computer system, and thus allowing the algorithm of the present invention to be used extensively.
