A video display system includes analog / digital converters (342, 346) for quantizing first and second video signals, representing first and second images respectively, at higher and lower levels of quantization resolution relative to each other. others. The analog / digital converters (342, 346) can operate at different sampling rates. The image shown is in the lower sample rate signal may appear to be undersampled, compared to the other image. A video display is synchronized with the first video signal. The second video signal is synchronized with the first video signal. A signal processing circuit modifies the first and second video signals to represent the first and second images respectively in formats smaller than that of the video display. A multiplexing circuit (300) combines the processed video signals to obtain a side-by-side display of said images. A circuit increasing the quantization resolution improves the perceived quality of the video signal having the lower level of quantization resolution. |
