    摘要: A video decompressing system with high-efficiency memory access capability has a memory device for storing reference frames which are read out for performing motion compensation in decompressing process. The reference frame has its pixels arranged as a plurality of horizontal lines for being stored in the memory device. If the pixels of one horizontal line can not be integrally stored in one row of the memory device, the horizontal line is broken into at least two lines for being stored in the rows of the memory device. At the end portion of the row where the horizontal line is broken, a tail section is allocated for duplicating and storing pixels that are the same as those of a macroblock at a starting position of the next row, so as to avoid the page break problem.

    摘要: A data communication circuit of a SDRAM for data communication comprises a plurality of data lines coupled to a plurality of data pins. The number of the data lines, according to an embodiment of the present invention, is less than the number of the data pins. When the data communication circuit receives/outputs data, one of the LDQM pin and the UDQM pin are enabled to receive/output a first part of the data. The other LDQM pin and the UDQM pin are enabled. Accordingly, the data communication circuit of the SDRAM, according to an embodiment of the present invention, is capable of transmitting more data using a bus with a narrow width.

    摘要: An output method for improving video image quality is provided. First, a frame data of a first frame is received, wherein the first frame may coincide with a first type or a second type. Thereafter, the first frame is subjected to a signal process step to output a processed first frame with a first standard, wherein the processed first frame comprises a first signal to noise (S/N) ratio. Next, a frame data of a second frame with a second standard is received, wherein the second frame coincides with a third type. Thereafter, a first decompression process of frame data is performed on the second frame to output a processed second frame with the first standard, wherein the processed second frame comprises a second S/N ratio. In addition, a difference between the first S/N ratio and the second S/N ratio is smaller than a predetermined minimum tolerance.
