Viral uncoating has not been as well studied. Previous notions were that all virus that entered a cell was opened up, or uncoated, simply as a consequence of being inside the cell.

The invention is an assay for identifying compounds that have anti-viral activity. Susceptible host cells are exposed to a potential viral inhibitor and then infected with a virus.

Common practice when decoding NTSC signals is for a “tint” or “hue” adjustment to compensate for possible differential phase errors between a QAM chroma signal and its accompanying burst reference. Tint adjustment is also useful in compensating for other possible system errors.
Additionally, tint adjustment together with saturation adjustment allows for variations in personal preference to be accommodated, permitting any color to be shifted in saturation and hue without affecting the gray scale. In order to retain this capability for video signals that do not experience NTSC decoding, such as component video signals, e.g., from a DVD player or set-top box, it is generally necessary to apply tint adjustment to the baseband color difference signals.
