A method and apparatus for providing two simultaneously available video outputs in two different spatial and/or temporal sampling formats derived from a common video source. A single sampling format conversion process is employed, which can be switched to drive either of two processed video outputs, such that one of the outputs has the same spatial and/or temporal sampling format as the common video source and the other output has a different spatial and/or temporal sampling format. Preferably there are provided two video source inputs having different spatial and/or temporal sampling formats either of which may be selected as the common video source. The video source selection can advantageously be changed without material discontinuity of output video spatial or temporal sampling phase. |
