摘要：
A method and apparatus for down-converting a digital video signal includes a synthesizer and a converter. The synthesizer receives a digital video signal including at least first and second DCT blocks of DCT coefficients, and synthesizes the first and second DCT blocks into a single synthesized DCT block having dimensions equal to the first and second DCT blocks. The converter converts the synthesized DCT block from the DCT domain to the spatial domain to produce an output digital video signal.
