Abstract: The present invention may be used to improve the quality of music output from audio systems by simulating the effect of low frequency signals in the human ear. This thus allows listeners to perceive the lower frequencies signals, even though the speakers may be incapable of providing such low frequency outputs. The present invention provides simple methods for processing enhancing bass effect in audio signals. The simple methods also result in the bass enhancement being computationally less intensive. The bass effect enhancement techniques described in a first and second embodiment are based on the response of sine and cosine transfer functions and on the directional independence of low frequency components. The human ear is unable to resolve directions from low frequency components. The bass effect enhancement technique described in a third embodiment is based on response of a exponential transfer function.

Abstract: A multichip integrated circuit apparatus includes first and second integrated circuit die mounted on opposite sides of a leadframe die paddle, with at least one of the integrated circuit die extending further toward the leads than does the die paddle. With this arrangement, the active circuit areas of both integrated circuit die can face in the same direction, and can be wire bonded to the same surfaces of the leads. This avoids wire bonding complications that are often encountered in multichip integrated circuit package designs.

Abstract: A method includes receiving image information representing at least one image. The image information defines multiple pixels in the at least one image. The method also includes identifying filter weights associated with the pixels. The filter weights are based on edge contents of at least a portion of the at least one image. In addition, the method includes filtering the image information using the identified filter weights.

Abstract: An apparatus, method, and computer program are capable of receiving and cross-correlating a first audio signal and a second audio signal. This produces a cross-correlated signal, which is used to identify a plurality of parameters associated with at least one of the first and second audio signals. The parameters are used to generate an indicator identifying an extent to which the first and second audio signals match.

Abstract: An improved digital cut-off control loop for black level adjustment in a video processor for controlling RGB output signals. The improved circuit advantageously provides a higher resolution of the black level adjustment, and a short cut-off convergence time when the TV set is switched on. The improved circuit can also blank the RGB output when the cut-off control loop has not converged to the correct level.

Abstract: A method of processing video data to detect field characteristics of the data, including processing pixel values of the data to obtain differences between the values of two successive fields of the data, processing the difference values to detect interlace patterns in the successive fields, determining if the successive fields belong to a progressive frame based on detection of the interlace patterns, and generating a progressive frame output indicating that a progressive frame has been detected. The pixel values of the first field of the successive fields and a subsequent field to the successive fields are processed to obtain further difference values to determine if the subsequent field is a redundant field, when the progressive frame output is generated.

Abstract: An audio processor, apparatus, and method use physical speakers to emulate one or more additional speakers. The physical speakers produce sounds that, from a listener's perspective, appear to come from at least one direction where a physical speaker is not present. Any number of additional speakers can be virtualized, such as three or five speakers that allow two speakers to emulate a 5.1 audio system.
