A method and apparatus to compress video data to smaller size and embed extra information into the compressed data using the integrated lossy and lossless compressions is described. The method can be used to compress reference frames of a video codec (coder/decoder) combines codec where the small noise is critical and to reduce bus bandwidth. Data transfer between an encoder and an external frame memory connected via an external bus in a video codec is reduced by compressing data from the encoder prior to inputting into the frame memory over the external bus, and decompressing the compressed data from the frame memory after retrieving over the external bus. Reference frames are compressed to variable size without causing any considerable artifact to reduce bus bandwidth between the encoder core and external memory. In the method, lossy and lossless compression is integrated to maximize the compression efficiency.

A method and apparatus for pattern recognition comprising comparing an input signal representing an unknown pattern with reference data representing each of a plurality of pre-defined patterns, at least one of the pre-defined patterns being represented by at least two instances of reference data. Successive segments of the input signal are compared with successive segments of the reference data and comparison results for each successive segment are generated. For each pre-defined pattern having at least two instances of reference data, the comparison results for the closest matching segment of reference data for each segment of the input signal are recorded to produce a composite comparison result for the said pre-defined pattern. The unknown pattern is the identified on the basis of the comparison results. Thus the effect of a mismatch between the input signal and each instance of the reference data is reduced by selecting the best segments from the instances of reference data for each pre-defined pattern.

A harmonic rejection mixer having a phase rotator fed by a local oscillator signal. The local oscillator signal has a reference frequency. The phase rotator produces a plurality of output signals, each one of the signals having a common frequency related to the reference frequency and having different relative phase shifts. A plurality of mixer sections, each one of the sections being fed an input signal and a corresponding one of the plurality of output signals mixes the local oscillator signal with the corresponding one of the plurality of output signals fed thereto. A combiner combines the mixer signal from the plurality of mixer sections into a composite output signal. A detector detects energy in a harmonic of the composite signal and for adjusting the output signal of the phase rotator to reduce the selected harmonic of the composite signal.

A single chip integrated circuit measuring circuit (1) for determining a characteristic of the impedance of an external complex impedance circuit (2) for facilitating characterization of the impedance of the complex impedance circuit (2) comprises a signal generating circuit (7) for generating a variable frequency stimulus signal for applying to the complex impedance circuit (2). A first receiving circuit (10) receives a response signal from the complex impedance circuit (2) in response to the stimulus signal and conditions the response signal. A first analog-to-digital converter (68) converts the conditioned response signal to a first digital output signal, which is read from the first analog-to-digital converter (68) through a first digital output port (14). The response signal from the complex impedance circuit (2) is a current signal, and a current to voltage converter circuit (64) converts the response signal to a voltage signal. A first RMS to DC level converting circuit (70) converts the AC voltage of the response signal to a DC voltage level, and a fourth multiplexer (67) selectively applies the voltage response signal or the DC voltage level signal to the first analog-to-digital converter (68), depending on whether it is desired that the first digital output signal should be indicative of the phase shift or amplitude change in the response signal relative to the stimulus signal. A second receiving circuit (20) receives the stimulus signal, and similarly converts the stimulus signal to a second digital output signal for facilitating comparison of the response signal with the stimulus signal.

A coupler-multiplexer permutation switch (CMPS) integrates multiplexng and switching functions on a single substrate. It has a single-mode/multi-mode backward coupler followed by a digital optical switch (DOS). In the CMPS, the single-mode waveguide channels are phase-matched through a grating with the corresponding, backward-propagating modes of a multi-mode waveguide. The different modes are subsequently separated in a digital optical switch. Different permutations are obtained by electronically controlling an effective-index distribution of DOS output waveguides.

The invention relates to Run length Limited-codes storage systems. In modern storage systems, the inter-track spacing is chosen to be relatively small to allow for high storage densities. As a result, when reading a target track, data written on side tracks may appear in the recovered signal. This inter-track interference is called cross-talk. The invention proposes a cross-talk cancellation scheme based on the minimization of the mismatch between the actual (dm+1m) and the expected (exp) run length between two transitions (xm, xm+1) of the (dm+1,m) signal. The proposed solution significantly improves the ramp-up properties of the receiver and allows more efficient hardware implementation.

The present invention relates to a reflective polarizer and a backlight unit including same and, more particularly, to a reflective polarizer and a backlight unit including same which can display excellent and uniform brightness throughout the visible light wavelength range in the following manner. Regardless of the incident angle of incident light, a discordance in the refractive index in one particular direction is minimized, and the transmissivity of polarized light targeted within the visible light wavelength range is uniform. Thus, light transmitted through the reflective polarizer is not biased toward a particular wavelength range, and the exterior is not colorful or a particular color due to rainbow-colored light. Because the reflectivity of polarized light not targeted within the visible light wavelength range is significantly large, the light is not biased toward a particular wavelength range.

An optical line terminal calculates a requirement threshold for each optical subscriber unit based on a difference between the time average allocated bandwidth of each optical subscriber unit and the target bandwidth, and notifies a corresponding optical subscriber unit of the calculated requirement threshold. The corresponding optical subscriber unit then notifies, based on the data amount accumulated in a buffer, the optical line terminal of a data amount, as a transmission requirement, up to a data separation that is less or equal to the notified requirement threshold and in which a maximum transmission amount can be transmitted. The optical line terminal then notifies the corresponding optical subscriber unit of a transmission permission amount in which the data equal to the transmission requirement of which the optical line terminal is notified can be transmitted. The corresponding optical subscriber unit then transmits the data amount corresponding to the transmission permission amount.
