摘要： Television images to be digitally recorded are divided into blocks and the discrete cosine transform DCT of each block is taken. The DC coefficient of each DCT block is scalar-quantized, and its AC coefficients are classified-vector-quantized (CVQ). The square of the value that part or all the AC coefficients among horizontal AC coefficients including a first AC coefficient and vertical AC coefficients including a second AC coefficient, according to the zigzag scanning sequence of DCT block, are subtracted from a representative value of a preset reference class. Using a multilevel compression method, lowest level codes are vector-partitioned by P-units at equal intervals with respect to each classified DCT block, and code books of representative vectors corresponding to the partitioned vectors are provided. Indices of corresponding representative vectors in respective code books and the classified codes are taken as encoding data corresponding to AC coefficients to keep a constant number of bits in the lowest level codes. Then, errors created in a preceding level are corrected. Code books of S-units of representative vectors corresponding to the errors are provided again, and corresponding indices and parity data in the respective code books are provided. Here, codes are output in which an image is more compactly compressed in lower levels, and higher levels have more elaborate picture quality. During tape recording, the codes descriptive of the scalar quantized DC term, the classification of the AC terms and the lowest-level vector-quantization index for each successive DCT block are grouped together for recording in a respective one of regularly spaced equal-length segments of the recording tracks. Decoding is performed in the reverse sequence of encoding. During a high speed search, only lowest level codes having a constant number of bits are decoded regardless of the complexity of the picture, so that picture quality is good enough to discern the nature of the images.

摘要： The present invention is related to a negative voltage generating circuit for reliably providing the semiconductor integrated circuit (IC) with a negative voltage. An electric charge pumping device generates a negative voltage by pumping an electric charge to a predetermined level supplied to one of a first node and a second node. A controlling device provides first and second pumping clock signal being clocked alternately every predetermined interval in response to a level of the negative voltage. A pumping controller controls an amount of electric charge supplied to the first node and the second node in response to the first and second pumping clock signals. Further, a reset controller resets the first node and the second node of the electric charge pumping means as the level of the negative voltage when the first and second pumping clock signals are inactivated.
