In this paper, a fast transform method is proposed to convert MPEG-2 8-tap discrete cosine transform (DCT) coefficients to H.264/AVC 4-tap integer transform coefficients directly ...
Transcoding is an important technique for reducing the bit rate or spatial resolution to meet the constrained transmission bandwidths and terminal capabilities. In this paper, we p...
To improve video quality and coding efficiency, H.264/AVC [1] has adopted several newer coding tools such as a 4?4 integer DCT and a method for calculating half pixels than the pre...
This paper describes novel transcoding techniques aimed for low-complexity MPEG-2 to H.264/AVC transcoding. An important application for this type of conversion is efficient stor...

The high definition video adoption has been growing rapidly for the last two years. The two high definition DVD formats HD-DVD and Blueray have mandated MPEG-2, H.264 and VC-1 as ...
