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.

In the present invention, content is comprised of a plurality of items of data, and a transmission cycle and others of data composing the content are varied corresponding to the importance and/or necessity and purpose of the data. In this way, for example, it is possible to set a shorter transmission cycle on high-necessity data than the transmission cycle of the low-necessity data, and to set a shorter transmission cycle on information such as summary information requiring fast viewing than the transmission cycle of detailed information.

The present invention is intended to realize a screen configuration according to a propagation environment and display capability by causing a server to transmit a plurality of pieces of screen configuration information describing a spatial arrangement of contents to a reception terminal and select, when the reception terminal receives a plurality of pieces of screen configuration information, screen configuration information and display the contents according to the propagation environment of the reception terminal and conditions such as display capability.
摘要:
The present invention allows the transmitting side to transmit a plurality of pieces of layout information that determines a display layout of at least one media and media data making up this layout information and allows the receiving side to receive the layout information and media making up this layout information transmitted from the transmitting side, select one out of a plurality of different pieces of layout information based on a reception state of this media and represent the media using the selected layout information.
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.
