Abstract: An OFDM receiver includes a CCI detector and a frequency-domain notch filter. The CCI detector detects whether or not the co-channel interference exists in a sub-carrier and lowers the weight of a distorted sub-carrier to eliminate the influence of the co-channel interference. The frequency-domain notch filter receives a frequency-domain signal and generates a notched frequency-domain signal.

Abstract: A video encoding method with support for editing when scene changed. The video encoding method reads and stores the pictures by the display order and detects whether the scene change occurred. The method encodes the pictures by the coding order when there are not scenes changed and encodes the pictures by a special coding process when there are scenes changed. Because the video encoding method encodes the pictures with considering the states of scenes changed and generates a new GOP when a scene change occurred, the video sequence can be cut into two parts by an image editing process without re-encoding. Therefore, the video can be edited without any loss and the editing performance of the editing process can be better.

Abstract: An apparatus for variable bit rate control in moving picture compression. First, a total activity measure for the current picture to be encoded in a set of consecutive pictures is calculated. Based on the total activity measure of the current picture and an activity-to-complexity ratio of a previously encoded picture of the same type in the set of consecutive pictures, a complexity measure of the current picture is estimated. A statistical complexity measure is then calculated from the complexity measure of the current picture. A target bit budget is allocated to the current picture depending on the instantaneous rate, the complexity measure and the instantaneous complexity measure. After encoding the current picture, the activity-to-complexity ratio for the current picture is computed based on the total activity measure, actual bits consumed by the current picture and an average of actual quantization step sizes used to encode the current picture.

Abstract: A method is provided to reduce strapping devices in a computer system having at least one configurable device, which includes the following steps. A configuration value stored in a non-volatile memory is first provided. During power-up and reset of the computer system, a processor reset signal and a bus reset signal of a high-speed peripheral bus are both asserted, wherein the high-speed peripheral bus is included in the computer system. When an operation clock of the high-speed peripheral bus reaches its working voltage and frequency, the configuration value is fetched from the non-volatile memory. The fetching step is repeated until a most significant bit (MSB) of a fetched configuration value changes from a first state to a second state. Subsequently, the configuration value fetched from the non-volatile memory is asserted to the at least one configurable device to configure the configurable device, and then the processor reset signal is deasserted, and the at least one configurable device is thereby completely configured.

Abstract: An apparatus and a method of controlling and tuning clock phase alignment with a dual loop of a hybrid phase and time domain for clock source synchronization in electronic devices are described. The coarse calibration unit generates a plurality of output signals, the output signals having a plurality of fixed phase intervals therebetween. At least one of the fixed phase intervals is equal to complete 360 degrees which are divided by the number of the output signals to cover the phase range of complete 360 degrees. The first fine calibration unit connected to the coarse calibration unit delays the output signals generated from the coarse calibration unit by coupling a programmable delay circuit to adjust the phase of a feedback signal toward the phase of a reference signal. The phase detector connected to the first fine calibration unit is used to detect a phase difference between the reference and the feedback signals and outputting an indicating signal corresponding to the phase difference between the reference and the feedback signals. The controller controls the coarse calibration unit and the first fine calibration unit to align the feedback signal to the reference signal according to the indicating signal generated from the phase detector. The rotating detector rapidly tunes the phase difference between the feedback signal and the reference signal by adding a number of time delays to the feedback signal when the feedback signal and the reference signal are miss-aligned.
