摘要 |
JPEG encoded data are entropy-decoded to quantized DCT coefficients which are sent to a prediction tap extraction circuit ( 41 ) and to a class tap extraction circuit ( 42 ). The prediction tap extraction circuit ( 41 ) and the class tap extraction circuit ( 42 ) extract what is needed from the quantized DCT coefficients to form prediction taps and class taps. A classification circuit ( 43 ) effects classification based on the class taps. A coefficient table storage unit ( 44 ) sends tap coefficients corresponding to the classes resulting from the classification to a sum of products circuit ( 45 ), which sum of products circuit ( 45 ) then effects linear predictive calculations, using the tap coefficients and the class taps, to generate decoded picture data.
