Abstract: A method for motion pixel detection with adaptive thresholds, according to the global motion information among the reference video fields, so as to correctly evaluate whether a missing pixel is in a static region or a non-static region, thereby reconstructing the missing pixel by an inter-field interpolation process or an intra-field interpolation process. If the amount of motion among the reference fields is large, there is high motion information among the reference fields, so the threshold is set to be small; if the amount is small, there is less motion information between the reference fields, and so the threshold should be set to be large.

Abstract: A ratio between an aspect ratio of a digital image signal and an aspect ratio of a display device is converted and a presence image part 2 of digital image data decoded by a digital image signal demodulating part is compressed laterally and is shifted to the center of an image area 1 made of the aspect ratio of the digital image signal and then an absence image part 3 is used as side panels 4 and digital image data made of the aspect ratio of the digital image signal is formed and outputted. Thus, even when the display device converts an image by a lateral uniform expansion method, a display image without lateral expansion can be outputted on a display screen.

Abstract: A television receiver for receiving digital and analog signals that reduces adjacent channel interference when receiving digital signals susceptible to interference caused by a lower adjacent NTSC signal. Upon receiving the digital signal, the receiver heterodynes the digital signal with a local oscillator (LO) signal to produce an intermediate frequency (IF) signal. A microprocessor searches a memory unit for stored information regarding the digital broadcast channel and determines the presence or absence of a lower adjacent NTSC channel. In the case a lower adjacent NTSC channel is present, the microprocessor shifts the frequency of the LO signal causing the IF signal to shift towards the lower band edge of a surface acoustic wave (SAW) filter present in a digital signal processor further attenuating the lower adjacent NTSC channel.

Abstract: A digital IF demodulator receives and demodulates an analog IF input signal to produce a digital audio signal and a digital video signal. The digital IF demodulator includes an A/D converter, a first digital complex mixer, a second digital complex mixer, and various digital filters. The first digital complex mixer receives the output of the A/D converter and down-converts the output of the A/D converter to baseband. Additionally, the picture carrier is recovered from the output of the first digital complex mixer, and fed back to a direct digital synthesizer to control the tuning accuracy of the first digital complex mixer. More specifically, a feedback loop is formed to so that the picture carrier is down-converted to DC so as to control the tuning accuracy of the first digital complex mixer. The complex output of the first complex mixer is further processed using Nyquist filtering and other filtering to recover the digital video signal.

Abstract: A luminance qualified vector display device provides a vector display that is gated by a specified luminance range. In one implementation three luminance gates may be used, one for luminance levels above a specified high luminance threshold, a second for luminance levels below a specified low luminance threshold, and a third for luminance levels between the specified high and low luminance thresholds. Also the luminance thresholds for the medium luminance range may be separately adjusted to overlap the high and low luminance ranges respectively. Each luminance qualified vector display may be displayed separately, may be overlaid for display using a different color for each luminance range, or may be displayed in different quadrants of a display device or window together with the normal, non-luminance qualified, vector display.

Abstract: The present invention provides a television receiver which receives television signals to display images on a CRT display, and includes a JPEG decode unit (21) for decoding JPEG (Joint Photographic Experts Group) compressed image data. The JPEG decode unit (21) detects image size of image data after decode processing stored in JPEG compressed image data from a memory card (6). In case the image size is larger than image display area of a CRT display (3) and activity ratio of a memory unit (22) is larger than a limit value, the JPEG decode unit (21) sends the image size to a CPU (25), and concurrently decodes the JPEG compressed image data in the memory unit (22) to generate the image data, and clips away half of the image data along the vertical direction and the horizontal direction.

Abstract: A method and apparatus for isolating a noise intolerant device, e.g., a phase-lock loop of a tuner within a television receiver, from source of noise. In one embodiment, the apparatus isolates a phase-lock loop integrated circuit (IC) from the bus, by providing an isolation buffer that allows the receiver to only pass data to the tuner's phase-lock loop IC when a tune command is issued by a processor. When not being tuned, the IIC lines to the tuner are held HIGH by a buffer until needed again to perform the tuning function. This allows the demodulation circuitry to use a setting for a carrier tracking-loop that optimizes bit error rate performance.
