A DEVICE AND METHOD FOR CONVERTING CODING COEFFICIENTS OF VIDEO SIGNAL

摘要

A device and method for converting coding coefficients of video signal, converts first coding coefficients to second coding coefficients, the apparatus includes: a first storage device (10) for storing the first coding coefficients; a second storage device (12) for storing a conversion matrix which converts the first coding coefficients to the second coding coefficients; a multiplication device (30) for executing the multiplying operation on the first coding coefficients and the corresponding parameters in the conversion matrix; a accumulation device (20) and a shift device (40) which are used for executing accumulating and shifting operation on the resulting values of the multiplication operation by the multiplication device (30) to obtain the second coding coefficients. In the invention, it is possible to convert between compression signals of different conversion cores, so as to make the various compression signals being compatible with each other, and being compatible with more standards and having more generality.
