Abstract: A method and apparatus is disclosed herein for reducing digital video image data. In one embodiment, the method comprises comparing a signature for one or more regions of a current frame of the image data to a signature of a corresponding region of one or more previous frames; and for a region of the one or more regions, sending the region to the data sink if comparing the signature results in determining that the signature of the region does not match a signature of a corresponding region of a previous frame available at the data sink.

Abstract: A panel module with simplified supporting structure and a portable electronic apparatus with the panel module are disclosed. The portable electronic apparatus includes a casing where the panel module is disposed. The panel module includes a frame and a bracket. The frame includes a reverse U-shaped passage. A display panel is fixed on the frame. The bracket includes a reverse U-shaped body and a plurality of fixing parts connected to the reverse U-shaped body. The reverse U-shaped body is accommodated in the reverse U-shaped passage. The fixing parts protrude out of the frame. The panel module is fixed on the casing by the fixing parts. Therefore, the invention uses the bracket with the reverse U-shaped structure to directly provide required fixedness and structure rigidity for the frame, so that an additional metal frame in the prior art for fixing a display panel together with a plastic frame can be omitted.

Abstract: A system of playing online or webpage games via instant messaging software includes at least one user terminal, at least one communication terminal and a game server. The user terminal installs instant communication software for logging on the instant communication server by a user terminal account ID and a user terminal password. The communication terminal logs on the instant communication server by a communication terminal account ID and a communication terminal password. The communication terminal establishes an online connection with the user terminal through the instant communication server to obtain the user terminal account ID and receive a game instruction from the user terminal. The game server includes a microprocessor and a game database for storing game information. If the communication terminal receives the game instruction, the communication terminal transmits the game instruction and the user terminal account ID to the microprocessor for the microprocessor to execute the game instruction.

Abstract: The image sticking erasing circuit includes a detection circuit and a switching circuit connected to the detection circuit. The detection circuit is for use in detecting a first voltage signal, which closely follows the variation of the voltage source, and a reference voltage, which loosely follows the variation of the voltage source. When the detection circuit determines that the first voltage signal is lower than a first threshold value, the switching circuit switches the gate of a driving transistor to a second voltage signal, which loosely follows the voltage source. When the detection circuit determines that the reference voltage signal is lower than a second threshold value, the switching circuit switches the gate of a driving transistor to a low voltage state.
