    摘要: A method and apparatus for supporting variable oversampling ratios when decoding vertical blanking interval data receives an indication of an oversampling ratio being used to sample a signal received during the vertical blanking interval. The sampled signal is also received. Then, based on the indication of the oversampling ratio being used, the data embedded in the vertical blanking interval is identified.

    摘要: A plurality of image signals corresponding to a first portion of a first row of an image are received. A plurality of first-row weighted image signals are generated by multiplying each of the plurality of first-row image signals by a first-row weight factor selected in accordance with digital differential accumulator processing. A plurality of image signals corresponding to a first portion of a second row of the image are received. A plurality of second-row weighted image signals are generated by multiplying each of the plurality of second-row image signals by a second-row weight factor selected in accordance with the digital differential accumulator processing. A plurality of weighted sum signals are generated by adding the plurality of first-row weighted image signals and the plurality of second-row weighted image signals. A plurality of vertically scaled image signals are generated from the weighted sum signals.

    摘要: A flicker filter is adjusted according to degree of alpha blending performed on a display signal. For some weakly showing graphics images, a lower flicker filter level may be implemented or the flicker filter may be turned off. A threshold for turning off the flicker filter may be programmable. Other embodiments are described and claimed.

    摘要: A mechanism for adaptive selection of anti-ghosting filtering accesses a first plurality of coefficients being used by the anti-ghosting filtering and compares a first set of one or more of the first plurality of coefficients to a first predetermined value. The mechanism then modifies the anti-ghosting filtering based on the results of this comparison. In one embodiment, the mechanism includes both an adaptive baseband equalization filter and a lookup table filter.

    摘要: Binding data sinks and sources across ring levels of a computer. A new binding channel is created and attached to a comm channel. A unique name is created for the binding channel, and a handle to the unique name is obtained at a relatively low priority ring level. The handle is passed to an unbound relatively high priority ring level code module.

    摘要: A hardware system is programmed with a common vertical blanking interval (VBI) scan line decoder to support capture hardware of multiple vendors. The common decoder includes a first and a second function for a capture driver associated with a capture hardware to describe to the common decoder, the sample rate and the line pitch employed by the capture hardware respectively. The common decoder further includes additional functions for the capture driver to confirm the common decoder's presence, register a call back function, specify a channel, and request decoding for a field.

    摘要: A current row and a next row of an image are selected in accordance with digital differential accumulator processing. A current-row weight factor and a next-row weight factor are selected in accordance with the digital differential accumulator processing. Weighted current-row image signals are generated by multiplying a plurality of image signals of the current row by the current-row weight factor and weighted next-row image signals are generated by multiplying a plurality of image signals of the next row by the next-row weight factor. Vertically scaled image signals are generated by adding the weighted current-row image signals and the weighted next-row image signals.
