摘要： In a moving picture decoding apparatus, a variable-length decoding circuit decodes motion vectors for each macroblock from a bit stream and stores the motion vectors. An error correction circuit calculates a reference vector for an error macroblock using the motion vectors to generate a corrected picture from a reference picture. An inverse-orthogonal transform circuit stores a difference value between direct-current (DC) components after Inverse Discrete Cosine Transform (IDCT) is performed thereon, in the memory for each macroblock. The error correction circuit further calculates a difference value of the DC component of the error macroblock using the difference values of DC components stored in the memory, to add the difference value calculated to the corrected picture generated from the reference picture.

摘要： A coding apparatus is for performing a deblocking filter process by dividing input moving image data into frames, and coding the moving image data by dividing the frames into macroblock lines and by shifting and changing, for each frame, a refresh area in which an amount of coding information allocated to a specific macroblock line is larger than that of another macroblock line. The coding apparatus includes a determining unit that determines that a refresh area in a current frame as well as a macroblock line in the current frame corresponding to a macroblock line that will become a refresh area in a frame being subsequently subjected to the coding process becomes a next refresh area. The coding apparatus includes a coding unit that codes the refresh area and the next refresh area by allocating a larger amount of coding information than an amount allocated to the other macroblock line.

摘要： Molten glass is press-molded by a metallic die in which a cylindrical body is provided in a vertically standing manner at a central part of a bottom surface of a bottomed hole and a molding surface corresponding to a chamfering shape of an outer peripheral edge surface of a glass substrate is consecutively formed in an inner peripheral wall, and a glass substrate precursor provided with the chamfering shape axially consecutive on an outer peripheral surface thereof and a through hole formed at a central part thereof is thereby formed. The glass substrate precursor is cut perpendicular to an axial direction to be separated into respective glass substrates. Next, the respective glass substrates are subjected to a lapping process and a polishing process, if necessary, to produce a glass substrate as a final product. According to the manufacturing method, a glass substrate for information recording medium whose inner and outer peripheral edge surfaces are chamfered can be manufactured with an improved efficiency. Further, a glass substrate having a small diameter can be manufactured with a high efficiency.
