Abstract
The present invention provides an apparatus for interpolation which is able to process input data with multiple video standards without sacrificing chip area. The interpolation unit comprises: a first interpolation unit for interpolating input data; a second interpolation unit for interpolating input data; a filter indicator for providing information to the first interpolation unit and the second interpolation unit; and an output unit for multiplexing and averaging output from the first interpolation unit and the second interpolation unit. The present invention also provides a motion compensation unit and a decoder for processing multiple video standards.
