Abstract: A Microsoft Windows BDA digital signal processing system includes a multimedia-processing device for processing a plurality of analog data packets and outputting a digital stream. A splitter receives and duplicates the digital stream to output a first digital stream and a second digital stream. A demultiplexer receives the first digital stream. When the first digital stream is a transport stream, then the demultiplexer demutlitplexes the first digital stream. A non-transport stream controller receives the second digital stream. When the second digital stream is a non-transport stream, then the non-transport stream controller processes the second digital stream. A processing method using the foregoing Microsoft Windows BDA digital signal processing system is also provided.

The elastic metallic conductive member has a crooked cross-section in a certain direction so as to be elastically stretchable in the certain direction, thereby in contact with both of the signal transmission connector socket and the securing plate to accomplish electric connection.

Abstract: An external device is used with a backend host operated with an operating system. The external device has a program and receives incoming data. The external device is operated with the backend host according to an operating method including the following steps. Firstly, the external device is connected to the backend host, and the external device is recognized by the operating system. Then, the external device is reconnected to the backend host to have the operating system recognize the external device as a memory device when the external device is unrecognizable by the operating system, so that the program is accessible and executable by the operating system to control the external device, or the external device converts the incoming data into at least one data file complying with the access format of a certain program in the operating system.

Abstract: A high-voltage pulse protection device includes an input connector, a separating capacitor and an output connector. A video receiving terminal of the input connector receives a video signal from a RF cable. An input terminal of the separating capacitor is electrically connected to a video transferring terminal of the input connector to receive the video signal. An output terminal of the separating capacitor induces and outputs a sub-signal response to the video signal. A video receiving terminal of the output connector receives the sub-signal, and a video transferring terminal of the output connector transfers the sub-signal to a video processing module.

Abstract: In a signal pickup method for a video recording and playing system, a signal is continuously received and stored in a data buffer of the video recording and playing system. Then, in response to an operation of a control device of the video recording and playing system, a pickup start point and a pickup end point are determined, thereby locating a first data address corresponding to the pickup start point and a second data address corresponding to the pickup end point in the data buffer. Afterward, the data between the first data address and the second data address are saved into a new file.

Abstract: A document camera is used to show image of an object on a display. In the document camera, a first image data of the object obtained by a video-capturing device is derived into a second image data and a third image data by an image processor in response to a zoom operation, wherein the second image data results in a zoomed image of the object and the third image data results in a scaled image of the object. In response to the zoom operation, there is also a mark frame data generated by a position information controller, which results in a mark frame. The zoomed image, scaled image and mark frame are then synthesized into a combined image by an image synthesizer, and the mark frame superimposes the scaled image to indicate a result of the zoom operation.

Abstract: A power control method used with a TV module of a portable electronic apparatus is used for selectively entering the TV module in a power-saving mode. At first, the portable electronic apparatus is activated. When the portable electronic apparatus is activated, the power supply condition of the portable electronic apparatus is detected. If the power supply condition of the portable electronic apparatus indicates that an external power source is used, the power-saving mode of the TV module is suspended. Optionally, the power-saving mode of the TV module is suspended if a priority setting condition indicates that play efficiency takes priority.
