Abstract: Described herein is a method and system for video sequence evaluation in the presence of cross-chroma interference. When the luma and chroma components in an analog video sequence are separated, the luma component may add interference to the chroma component. This is called cross-chroma interference. In the evaluation of the video sequence, the cross-chroma interference may be interpreted as motion, noise, or other artifacts. By reducing the cross-chroma interference during the evaluation, motion and noise can be identified with greater probability. The proper identification can aid motion estimators used in video coding and motion compensated temporal filtering, and it can aid video filters that do not utilize motion compensation.

Abstract: According to one embodiment, an IP converter converts an interlaced color difference signal, in which the number of pixels in a vertical direction of a color difference signal is half that of a luminance signal, into a progressive color difference signal. A diagonal correlation detector detects a diagonal correlation of the progressive color difference signal, and obtains a correlative direction detected signal. A controller outputs a field selection signal to determine whether the progressive color difference signal is a signal in a top or bottom field. And a pixel generator changes a ratio between pixels of an nth and an n+1th line of the progressive color difference signal according to the field selection signal, when generating a new pixel by using corresponding pixels of the nth and n+1th lines based on the correlative direction detected signal.

Abstract: While a user of a digital television gives a command to switch from a first channel to a second channel, a comparison between a first remembered volume of the first channel and a second remembered volume of the second channel is provided. According to the result of the comparison, a currently-used volume of the second channel may be adjusted from the first remembered volume to the second remembered volume iteratively and by step volumes so that the adjustment of the currently-used volume of the later channel is not annoying for the user. Moreover, the user is also allowed in determining a preferred volume to be the currently-used volume of the second channel. While the user of the digital television flips between channels, unnecessary updates in a volume setting of the second channel are abandoned.

Abstract: A method for automated channel installation comprises the following steps. In step (A), a frequency scanning operation is executed to lock on to a frequency. In step (B), it is determined whether the frequency scanning operation is complete, if so, the process proceeds to step (F), otherwise, to step (C). In step (C), it is determined whether the locked frequency corresponds to a reserved channel number, if so, the process proceeds to step (D), otherwise, to step (E). In step (D) the corresponding reserved channel number is assigned to the locked frequency, and then proceeds to step (A). In step (E), the locked frequency not corresponding to the reserved channel number is stored in a caching table, and then proceeds to step (A). In step (F), an unused channel number is assigned to the frequency stored, if any, in the caching table.
