摘要
A method and system transcodes an input video based on a first transformation kernel to an output video based on a second transformation kernel. The first and second transformation kernels are different, and the transcoding is performed entirely in a transform-domain. Coefficients of a single transform kernel matrix are determined. Then, input coefficients of the input video are converted to output coefficients of the output video using only the single transform kernel matrix. The input video can be based on DCT coefficients, and the output video can be based on HT coefficients. Alternatively, the input video can be based on HT coefficients, and the output video can be based on DCT coefficients. In addition, the ouput video can have a reduced a spatial resolution from the input video.
