Abstract: A power management device is adopted in a memory device which includes a first memory unit and a second memory unit, including a first voltage regulator, a second voltage regulator, and a controller. The first voltage regulator receives a supply voltage from an external supply source and provides a first internal voltage to the first memory unit. The second voltage regulator receives the supply voltage from the external supply source and provides a second internal voltage to the second memory unit. The controller independently enables or disables the first voltage regulator and the second voltage regulator according to a control signal.

Abstract: A storage medium including a plurality of memory cells, a plurality of transmission lines, a driving module and a floating detection module is disclosed. The memory cells store data. The transmission lines are coupled to the memory cells. The driving module accesses the memory cells via the transmission lines. The floating detection module includes a reset unit, a plurality of connectors and a detector. The reset unit is coupled to a detection line. Each of the connectors is coupled between one of the transmission lines and the detection line. The detector determines whether a state of at least one of the transmission lines is a floating state according to a level of the detection line.

Abstract: Embodiments of the present disclosure disclose a method and apparatus for storing and playing a 3D video source. The method includes: alternately storing video frames of a left-eye video source and a right-eye video source in media data storage units of a multimedia storage file in a chronological order; and storing the media information of the left-eye video source and the right-eye video source in different media information storage units of the multimedia storage file. With the above method, when a player client plays a 3D video online, the client player is able to synthesize 3D video with the left-eye video source and right-eye video source obtained from the downloaded media stream data while simultaneously downloading continuous media stream data of a multimedia storage file. The client player can synthesize 3D video without all the download being complete, to thereby play while downloading.

Abstract: An image rotation method and an image rotation system for a video player are provided. The image rotation method includes the following steps. Firstly, an image rotation request from a terminal is received. Then, a source video file is decoded and a rotation processing operation is performed on the decoded source video file in response to the image rotation request, so that a rotated image of the source video file is displayed. At last, the rotated image is displayed on a display device of the terminal. By the image rotation method and the image rotation system, the image in the video player can be rotated by a specified angle. Consequently, the problems of the conventional video player will be overcome. Moreover, since the problems of causing the compressed and distorted image are eliminated, the quality of the played and displayed image is enhanced.

Abstract: Embodiments of the present invention relate to a font match technology, and in particular relate to a technology for performing font match with attribute values of a font. A method for font matching may include generating a two-dimensional link matrix based on available fonts and attribute values of the available fonts, receiving a font match query, and determining a font matching the received font match query from the available fonts by using the two-dimensional link matrix. Font matching may be implemented automatically, quickly, and accurately, without the need of manually randomly trying each font of a plurality of available fonts. Meanwhile, this method is independent from text processing software and may be called by any arbitrary text processing software (application). Moreover, this method allows the user to flexibly configure selection of the font attributes so as to perform font match more efficiently.
