A method for predicting motion compensation for determining of an input image based on a motion vector of the input image from this input image to a reference image which has been sampled at a first set time, and the method includes calculating a motion vector of the input image based on a move, at a second set time, of a block unit which is a part of the input image and consists of a plurality of pixels, and calculating a motion vector of the reference image based on a move, at the first set time, of a block unit which is a part of the reference image and consists of a plurality of pixels. Move compensation of the input image is calculated both from the motion vector of the input image and from the motion vector of the reference image, to thereby realize a method for determining motion compensation with high precision.

A stream editing system is provided which is designed to switch one of two input streams used in an editing operation to the other at an edit point set in each of the streams. The system includes two decoders and at least one encoder. In the editing operation to combine the two streams to produce a single stream, the system re-encodes only a trailing portion of one of the streams with a leading portion of the other stream which are defined across the edit points and uses the other portions of the streams as they are, thereby minimizing a deterioration in signal quality caused by the re-encoding of the streams.

An apparatus and method for forming solder interconnection structures that reduce thermo-mechanical stresses at the solder joints of a semiconductor device and its supporting substrate. In one embodiment, the solder interconnection structure of the present invention comprises a semiconductor device and a substrate having a plurality of solder connections extending from the substrate to electrodes or bond pads on the semiconductor device. A multilayer structure is disposed between the semiconductor device and substrate filling the gap formed by the solder connections. The multilayer structure includes a first layer and a second layer, each having a different coefficient of thermal expansion. Thus, in accordance with the present invention, the stress concentration points are moved away from the solder joints of the semiconductor device and substrate to a point located between the first and second layers of the filler structure.

A system and method for filtering a digital signal having a relatively high data rate uses circuitry which operates at a lower data rate. The filter includes an input section which receives the input signal and which divides the input signal into a plurality of contiguous segments. The system also includes a first filter which receives samples representing one of the plurality of segments and adjacent samples from the next contiguous one of the segments and which filters all of the received samples to produce a first filtered signal. A second filter receives samples of the next contiguous segment and filters those samples to produce a second filtered signal. The filtered signals are combined by providing the samples of the second filtered signal immediately after the samples of the first filtered signal to produce a filtered output signal. The invention also relates to using respective timing signals associated with the segments to determine when the samples of the first and second filtered signals are provided.

A multiplex signal processing apparatus in a singal transmitting and receiving system includes at the transmitting side: a first amplitude-modulator for modulating a first carrier by a main signal to obtain a vestigial sideband, amplitude-modulated main signal; a second amplitude-modulator for modulating a second carrier which has the same frequency but differs in phase by 90.degree. from the first carrier by a multiplex signal to obtain a double sideband, amplitude-modulated multiplex signal; an inverse Nyquist filter for filtering this signal to obtain a vestigial sideband, amplitude-modulated multiplex signal; and an adder for adding the vestigial sideband, amplitude-modulated main and multiplex signals to obtain a multiplexed signal. The apparatus at the receiving side includes: a Nyquist filter for filtering the multiplexed signal; a carrier regenerator for regenerating the first and second carriers from the multiplexed signal; a main signal detector for detecting the main signal from the multiplexed signal passed through the Nyquist filter by using the first carrier; a filter for removing quadrature distortion from the multiplexed signal; and a multiplex signal detector for detecting the multiplex signal from the multiplexed signal passed through the filter by using the second carrier. By inverse Nyquist filtering the auxiliary signal in quadrature to the picture carrier, a normal synchronous receiver will produce a conventional television signal without distortion (crosstalk) caused by quadrature distortion of an auxiliary signal containing additional picture information while at the same time allowing relatively simple demodulation of the auxiliary signal in improved receivers without adding distortion.
