A difference of coordinate values stored adjacent to each other is compressed by means of a statistical coding system when reading out outline font data storing coordinate values necessary for drawing a contour of a character in order of drawing the contour in a clockwise or counterclockwise direction and also a category of a line connecting a pair of coordinates simultaneously, followed by compressing the coordinate values of the outline font data. A value of a result of subtracting 'A&#x2212;1' from a difference of coordinate values is determined to be a difference value of coordinates if the difference of coordinate value is equal to or greater than a certain value A, and a code expressing the difference value of '0' is added in front of the codes of difference values that are smaller than the value A in the case of a category of line connecting adjacent coordinates to each other being a straight line.

System, method of controlling system and apparatus

A medium storing a program for display control. When the program is executed by a computer realized in a mobile terminal, the mobile terminal operates as follows. An area-information storing unit stores information on a first display area of an external display device and a second display area of a built-in display. A screen-data production unit acquires content to be displayed, and produces screen data corresponding to the first display area. An entire-image display unit divides the screen data into partial areas each corresponding to the second display area, adds to the entire screen data area-display data indicating the extent of each partial area and a corresponding identifier, and displays the screen data on the external display device. On receipt of an identifier, a partial-image display unit extracts a portion of the screen data for a partial area corresponding to the identifier, and displays the portion on the built-in display.

One new file and one old file are sequentially compared from the heads of the files on a predetermined data unit basis. If a data match is found, transfer information showing a position and a data length of the old file is output. If a data mismatch is found by the sequential comparison, the old file is searched in both directions from the data position where the mismatch had been found in the old file, thereby finding a portion which matches with the data of the new file. If the matching portion can be found, shift information up to the matching portion on the old file is output. If the matching portion cannot be found, new data is added to transfer replacement information showing a length of data of the mismatching portion of the old file at a position until the matching portion can be found, and the resultant transfer replacement information is output.

Differential data forming method, program, recording medium, and apparatus

A data management system including a storage and activating an application so that the application accesses contents in the storage and processes the contents. The data management system also monitors access of the application to the contents by associating information for the application brought into an activated status with information for the accessed contents. The data management system also enciphers the contents with the application information when the activated application writes the contents into the storage while deciphering the contents with the application information when the activated application reads out the contents.

A Bezier curve constituting outline font data represents a curve by four coordinate values of a start point, an end point, and two control points. The curve is represented by two coordinates of the start point and the end point in collinear approximation, and by three coordinates of the start point, an intersecting point of two lines, and the end point in bi-linear approximation. In curve pattern approximation, when 32 curve patterns are prepared, the curve is represented by 5-bit data of two coordinates of the start point and the end point, and a pattern number. By effectively employing these three kinds of processes, it is possible to represent a Bezier curve constituting the outline font data with a reduced data volume.

A stream data recording apparatus records stream data in such a manner that the head of each video coding unit and the head of a series of audio coding unit corresponding to each video coding unit contained in the stream data coincide with the heads of access units of a recording medium. Utilizing the structure of stream data so recorded and the random accessibility of the recording medium, a stream data replaying apparatus and a stream data editing apparatus replay or edit the stream data freely on a video coding unit basis. By replacing stream data recorded on the recording medium on a video coding unit basis, the recording apparatus realizes endless recording that does not require complex file manipulation.

The present invention relates to a sending method of pay contents in a communication system which carry out communication through predetermined communication network (e.g., radiotelephone network or the like) using a predetermined first communication scheme (e.g., CDMA scheme or the like). The sending method includes radio terminals which carry out peer-to-peer communication using a predetermined second communication scheme (e.g., infrared communication, communication adhering to Bluetooth standards), and a carrier which carries out communication using the first communication scheme with each of the terminals. When pay contents possessed by a first radio terminal are transferred to a second radio terminal, first, permission of transfer of the pay contents to the second radio terminal is received from a carrier and then, the pay contents are transferred. After the pay contents are transferred to the second radio terminal, the carrier is informed of completion of transfer operation.

Difference data reception unit receives difference data for all segments and stores it in nonvolatile memory. Restoration processing unit stores restoration process segment number indicative current process segment in the nonvolatile memory, and then restores segment data from difference data and stores it in nonvolatile memory. Overwrite processing unit stores overwrite processing segment number indicative of immediately preceding process segment nonvolatile memory, and then reads restored data which is restored on the immediately preceding segment from nonvolatile memory and overwrites it onto the data to be written of the volatile memory. If the power supply is interrupted during restoration process of segment data, a resuming processing unit resumes restoration process from the head of the segment of the restoration process segment number and if the power supply is interrupted during the overwriting process of the segment data, resumes the overwriting process from the head of the overwrite processing segment number.
