摘要： The present invention provides an ADC apparatus and method for improving effective bit resolution and suppressing digital reconstruction artifacts with an anti-aliasing filter and an over-sampled input. ADC resolution can be increased by combining a dither signal with a sampled signal and then after digitization, filtering out the dithered signal. Designing a notch in the filter corresponding to the attenuation frequency attenuates residual effects.

摘要： A method of transmitting video data includes receiving a frame of video data of a first resolution from an image capture device at a video transmission device and generating interlaced fields of the frame of video data at the video transmission device by applying a filter with a different set of filter coefficients to at least one field than is applied at least one other field. A method of producing video data of a particular resolution includes generating estimated high resolution video data from low resolution video data received at a display device, producing estimated low resolution video data from the estimated high resolution video data by applying a filter to the estimated high resolution video data, differencing the estimated low resolution video data and the received low resolution video data to generate difference data, and using the difference data to generate new estimated high resolution video data.
