Abstract :
This paper proposes a method to perform the inverse transform operations for three popular video compression standards H.264, VC-1 and MPEG-4 using the concept of delta coefficent matrix. We designed the unified inverse transform circuit based on the proposed method. Our circuit supports 4-point and 8-point transforms for H.264, VC-1 and MPEG-4. The proposed unified circuit was verified on the SoC platform board synthesized into a gate-level circuit using 130 nm standard cell library and showed its efficiency in terms of the area.
