    摘要： The present invention generates watermark from ID information that uniquely identifies a program distribution destination, inserts the generated watermark in a program, and prevents the program from operating correctly if the watermark is tampered with, and also inserts the same watermark verification code in a program regardless of the distribution destination. By this means, it is possible to prevent detection of watermark verification code constituting a watermark by means of collusion attack.

    摘要： A media receiving apparatus capable of preventing media from being positioned in an invalid display area or a program from being temporarily stopped, even if the vertical/horizontal ratio of the resolution of the display section is switched while a broadcast or streaming program is being displayed. In this apparatus there are a plurality of display sections D1 and D2 with different resolutions, and a display directive section (303) directs a display section to be set as active in accordance with the mode of use of the user. A layout information selection section (304) selects a layout corresponding to the resolution of the display section indicated by the display directive section (303) from layout information that includes layouts corresponding to display sections D1 and D2 distributed from a media distribution apparatus, and in accordance with the selected layout a media display control section (306) selects media distributed from the media distribution apparatus, performs conversion processing comprising enlargement or reduction, and displays media on the display section designated by the display directive section (303).

    摘要： An apparatus includes a storage section that stores stored content, a content receiving section that receives content, a received content storage section that stores received content, and a playback section that plays back the stored content or the received content. A playback control section controls the playback section to switch between playing back the stored content and playing back the received content. A content list management section manages a content list that stores combinations of an address of content relating to a location within a predetermined area, and the location. A location detection section detects current location information and a received content determination section determines content that should be received from the content list based on the current location information. The content receiving section receives content relating to a current location determined by the received content determination section and the playback control section controls the playback section to switch between playing back the received content and playing back the stored content.
