Abstract: A method for realizing virtual multi-channel by spectrum analysis is disclosed. The low-frequency-effect sound data is obtained by averaging sound data of left and right channels in the two-channel sound source and filtering the average by a first low pass filter. The central channel sound data is obtained by averaging sound data of the left and the right channels in the two-channel sound source and filtering the average by a second low pass filter. The surround right and left sound data is obtained by copying sound data of the left and the right channels in the two-channel sound source, respectively.

Abstract: A method for controlling an optical pickup head of an optical processing apparatus is provided. A first lead-lag compensator is disabled and a second lead-lag compensator is enabled when the optical pickup head switches from a following mode to a seeking mode. Then, an initial operating factor of the second lead-lag compensator is determined according to a last input value and a last output value of the first lead-lag compensator. An initial kick force of the actuator in the seeking mode is calculated by realizing the last input value and the last output value of the first lead-lag compensator immediately before the first lead-lag compensator is disabled. Finally, the optical pickup head is actuated to perform a seeking operation with the initial kick force.

Abstract: The present invention improves the drawback of requiring more clock signals in conventional high-frequency serial-to-parallel conversions that often use multi-phase clock circuits. The needed number of phase clocks is the bit width of the parallel data. In addition to effectively reduce the number of required clocks, the present invention can further solve the setup time problem associated with the switching one of two parallel data receivers as the parallel data output. A pre-register is employed in the converter of the present invention. Since this pre-register does not need switch control, it does not have the setup time problem during parallel data switching.

Abstract: A method for synthesizing a clock signal with multiple frequency outputs for use in a converter for converting a non-interlacing scan data into an interlacing scan data is disclosed. The converter provides a first reference clock signal with a frequency F1. The method includes the steps of receiving the first reference clock signal with the frequency F1 to generate and output a clock signal with a frequency F1nullN, proceeding a divided-by-P1 and a divided-by-P2 operations on the clock signal with a frequency F1nullN, respectively, to output a first output clock signal with a frequency F1nullN/P1 and a second output clock signal with a frequency F1nullN/P2, respectively. The value P2/P1 correlates to a ratio of the pixel number of a horizontal scan line in the non-interlacing scan data to that in the interlacing scan data. In addition, a clock signal synthesizer with multiple frequency outputs is also disclosed.

Abstract: This invention discloses a long-distance network transmission structure and associated device thereof. The invention utilizes the CAT-5 transmission line network to achieve a high-speed long-distance network tranceiving. A DSP PHY (Digital Signal Processing Physical) is employed in the long-distance network transmission structure to receive a data signal from the transmission line. The signal is then driven to clients with a common PHY without DSP capability or a DSP PHY. Through such a DSP PHY, the signal can be transmitted over 3000 ft and the transmission rate can reach duplex 100 Mbps. Two pairs of cords inside the CAT-5 network transmission line are used to provide the full duplex data tranceiving and the other two spare cords provide electrical power for a repeater. Therefore, the long-distance transmission structure and associated device thereof can effectively reduce the cost for both network service providers and clients and facilitate the installation.

Abstract: The invention discloses a packet switching load balance device and method. In a trunking-port network environment, a ticket assigner and a ticket distributor together achieve the output load balance during the transmission process of packet switching. The ticket assigner assigns one of tickets to a packet received by a logical port, and the ticket distributor determines which one of the physical output ports to transmit the packet according to the assigned ticket. In the transmission process, a load monitor dynamically adjusts the ticket distribution scheme used for the ticket distributor, thus the load balance is optimized.

Abstract: A method of automatically refreshing the display screen of a terminal and the computer program thereof is accomplished by incorporating a subroutine for periodically polling the connection status of a terminal into a main program running on host. A polling period is set in the main program, and a software interrupt is generated to invoke the execution of a corresponding interrupt service routine when the polling period is reached. The interrupt service routine contains a polling subroutine for polling the connection status of the terminal by sending a control string to the terminal and recording the polling result. The present polling result will be compared with the previous polling result to check whether the connection status of the terminal is changed. If the connection status of the terminal is changed from off-line to on-line, a display screen refresh subroutine is executed to refresh the display screen of the terminal.
