Abstract :
In this paper we describe a fast picture size conversion with deinterlacing for digital video (DV) to MPEG-4 transcoding. By an integration of matrices operation of resolution conversion with de-interlacing and by exploiting local symmetries in the matrices, very fast conversion can be obtained. The speed up factor of the conversion is up to 1.6 and 5 for multiplication and addition, respectively, when compared with baseband domain conversion. The transcoding experiments also show that the proposed method can achieve almost the same PSNR performance as that of baseband domain conversion.
