Abstract: The present invention relates to method and apparatus for video coding by ABT-based just noticeable difference (JND). For building the just noticeable difference model, spatial content information (SCI) is used to represent the spatial appearance similarity between one macroblock and its sub-blocks and the motion characteristic distance (MCD) is used to represent the motion characteristics similarity between one macroblock and its sub-blocks. For intra frames, the balance strategy based on the obtained SCI of the macroblock is used to generate the ABT-based JND model. For inter frames, the balanced strategy based on the obtained SCI and MCD of the macroblock is used to generate the ABT-based JND model. Using the ABT-based JND model, the residual coefficients for each block in a frame is filtered to obtain a reduced set of residual coefficients for transmission without degradation in visual quality.

Abstract: Improved arrays of high voltage vertical-emitting LEDs that generate substantially lower heat than conventional LED arrays are provided. In particular, the present invention provides an array of high-voltage vertical LEDs each of which includes a first electrode positioned on a light-emitting face and a second electrode. A conductive matrix surrounds each LED and electrically communicates with each of the electrodes while an electrically-insulating material is positioned between adjacent diodes such that a first electrical current path is defined between the second and first electrodes through each diode. An isolating material is positioned in the conductive matrix between adjacent LEDs to isolate the adjacent second electrodes from one another. Further positioned between adjacent diodes is a material capable of permanently lowering its resistance to provide an alternate electrical pathway following a failure of an individual LED. High reliability high voltage vertical LED arrays are thereby provided.

Abstract: An on-chip temperature sensor circuit can be implemented in a standard complementary metal-oxide-semiconductor (CMOS) process using PNP transistors. A pair of transistors have collector currents that are sensitive to voltage, both directly and due to saturation currents. A scaling resistor connects to the emitter of one transistor and its voltage compared to the other transistor's emitter voltage by an error amplifier that generates a bias voltage to current sources that are proportional to absolute temperature since the saturation current sensitivity is subtracted out. The current is mirrored to sink current through a multiplier resistor from an output. An amplifier connected across the multiplier resistor compares a reference voltage to set the DC bias independent of temperature sensitivity. The temperature sensitivity is proportional to the ratio of the multiplier resistor and the scaling resistor, and is multiplied by a mirroring factor. A differential output may also be provided.

Abstract: In a broadcast receiver for receiving a digital broadcast signal that carries time division multiplexed content programs or channels configured for power saving modes, the tuner, the ADC, the sub-modules within demodulator core, and the decoder are partitioned into multiple power domains forming a signal data processing pipeline with stages that are corresponding to the power domains and according to the boundaries of the data processing steps. During burst timeslot, only the power domain that is processing the signal data is turned on. Once the processing is completed the power domain is turned off. The power domains are turned off during non-burst timeslot. The ADCs and the first power domain are turned on one timeslot prior the beginning of the next burst timeslot. Therefore, the receiver can simply disregard any residual data in the processing pipeline from the last burst cycle and data flushing is not necessary.

Abstract: A frame-rate converter reduces halo artifacts along edges of moving objects. Halo artifacts occur on interpolated frames where a moving object covers and uncovers pixels along its edges. Motion estimation among three original frames produces hybrid direction motion vectors that are bi-directional for background and objects, but are unidirectional for covered and uncovered regions, since motion vectors with large matching errors are deleted. Covered regions in the interpolated frame are detected as intersecting only a forward but no backward hybrid motion vector. Bi-directional motion estimation from the hybrid motion vectors of two original frames produces refined motion vectors for the interpolated frame. Refined motion vectors in the covered regions are deleted and replaced with hybrid motion vectors from the original frames. Hybrid motion vectors from the original frames are assigned to the critical covered regions rather than using interpolated vectors in the covered regions, reducing halo artifacts.

Abstract: An analog-to-digital converter (ADC) has a chopper-stabilized sigma-delta modulator (SDM). The SDM uses switched-capacitor integrators to sample, hold, and integrate an analog input in response to non-overlapping multi-phase clocks. Chopper multipliers are inserted on the inputs and outputs of an op amp in a first stage integrator. The chopper multipliers swap or pass through differential inputs in response to non-overlapping chopper clocks. A master clock operating at a frequency of the multi-phase clocks is divided down to trigger generation of the chopper clocks. Delay lines ensure that the edges of the chopper clocks occur before the edges of the multi-phase clocks. The chopper multipliers have already switched and are thus stable when multi-phase clocks change so charge injection at switches controlled by the multi-phase clocks is not immediately modulated by chopper multipliers. This clock timing increases the time available to respond to charge injection at switches improving linearity.
