Digital video format conversion by upsampling decompressed data using on-the-fly interpolation and color conversion

Abstract

The present invention is related to an apparatus for digital video format conversion for a decompressed digital video data outputted from a decompressor, which includes a video interpolation device processing the decompressed digital video data by way of on-the-fly interpolating and filtering procedures to obtain an interpolated and filtered digital video data, and a color space converter electrically connected to the video interpolation device for converting the interpolated and filtered digital video data processed by the on-the-fly interpolating and filtering procedures from a first color space into a second one to complete the digital video format conversion. The present apparatus processes the decompressed digital video data by way of on-the-fly interpolating and filtering procedures and therefore the resolution of an original frame can be shown on a computer monitor to obtain a good frame quality. In addition, the present invention executes the digital video format conversion on the line basis instead of frame basis so that the hardware circuit can therefore be simplified to be co-integrated in an IC together with the decompressor to reduce the cost.
