TL;DR: In this paper, the problem of managing copyright by an image file itself and providing a function for unitarily managing also the restriction of the copying or the like of the image file as well by turning the file itself to a program or a module executed on an OS is addressed.
Abstract: PROBLEM TO BE SOLVED: To unitarily manage copyright by an image file itself and to provide a function for unitarily managing also the restriction of the copying or the like of the image file as well by turning the image file itself to a program or a module executed on an OS. SOLUTION: In a reference code S21, stored image data and the data form are specified. Then, in the code 22, inside a binary code in this image file, a password, the number of times capable of outputting data beforehand or the valid time limit of a program file and the number of times of allowing continuous erroneous password specification are specified. Then, in the code 23, the present date and time and the number of times of the continuous erroneous password specification are set and all information specified or set from the code 21 to the code 23 is ciphered. Then, in the code 24, all the ciphered information is stored as the image file.

TL;DR: In this article, a method and apparatus for converting different format content into one or more first common formats is presented, which allows content that is received in multiple, different formats to be converted into one standard format for manufacturing and, optionally, into an Internet format rather quickly.
Abstract: A method and apparatus for converting different format content into one or more first common formats. This conversion method allows content that is received in multiple, different formats to be converted into one standard format for manufacturing and, optionally, into an Internet format rather quickly. This method allows the content to be available in both the production master and Internet formats nearly simultaneously. The converted Internet ready content file can be “bundled” with its associated metadata in another step and entered into a database.

TL;DR: In this article, a technique for permitting a web page to include multimedia programs that are to be executed at the time that the page is displayed such as in an advertisement is presented.
Abstract: A technique for permitting a Web page to include multimedia programs that are to be executed at the time that the page is displayed such as in an advertisement The invention uses decompressors built into Web browsers and written in native code such as Graphical Image File (GIF) decompressors to encode not only images but also other information such as animation program code and sounds As a result, special decompression software and/or animation plug-ins need not be downloaded to the Web browser prior to displaying an animated multimedia presentation as part of a Web page advertisement

05 Jan 2005TL;DR: In this paper, a microprocessor in a digital broadcast receiver outputs image data displaying a menu in a sub-screen when instructed by a user to display the menu: if received broadcast signals are those of an HD broadcast, and if the image format of a television, to which data are output, is 1080 i or higher, and further if the screen size of the television, which is used for displaying the menu, is 37 inch or larger.
Abstract: A microprocessor in a digital broadcast receiver outputs image data displaying a menu in a sub-screen when instructed by a user to display the menu: if received broadcast signals are those of an HD broadcast, and if the image format of a television, to which data are output, is 1080 i or higher, and further if the screen size of the television, to which data are output, is 37 inch or larger; namely if characters in the menu are unlikely to be corrupted even when the television displays the menu in the sub-screen, and if there is no possibility that characters in the menu become too small to be identifiable. Thereby, it becomes possible for the television to display the menu in the sub-screen if the user can identify characters in the menu even when the television displays the menu in the sub-screen. Accordingly, the user can input setting of menu items while watching broadcast images.
