Abstract:
Apparatus for processing a digital video signal including video imagery associated with at least one of a plurality of transmitted display formats to produce an output video signal suitable for presentation on a display device, said display device having associated with it a single predetermined horizontal scanning frequency, said apparatus comprising:a horizontal resizer, for adapting a horizontal format of said digital video signal in response to a first control signal; a vertical resizer, for adapting a vertical format of said digital video signal in response to a second control signal; a frame rate converter, for adapting by an integer multiple a frame rate of said digital video signal in response to a third control signal; and a controller, for generating said first, second and third control signals in response to the transmitted display format of the video imagery included within said digital video signal; wherein said controller causing said horizontal resizer to adapt the horizontal format of said digital video signal to a size compatible with said predetermined horizontal scanning frequency of said display device; said controller causing said vertical resizer to adapt the vertical format of said digital video signal to a size compatible with said adapted horizontal format of said digital video signal; and said controller, in the case of an input video signal having a frame rate selected from the group of 24 and 25 Hz, causing said frame rate converter to multiply by n integer greater than 2 the frame rate of said digital video signal.
