    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： 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： According to the media server 100 and the network control apparatus 200, upon distributing a plurality of media data to the media receiving apparatuses 400 having different transmission rates by broadcasting or multicasting, the distribution precedence is attached by associating the program control information and the media data. The distribution precedence attached to the program control information is set same as or lower than the distribution precedence of all media data included in the program concerned. Then, depending on the distribution precedence, the transmission possible media data and the program only are selectively distributed. The program control information relating to the program that includes the receivable media data by the media receiving terminal apparatus 400 only is selected and received. This way, the receivable media data is distributed depending on the transmission environment of the media receiving apparatus. It is possible to prevent the media receiving apparatus selecting the invalid program.

    摘要翻译： 根据媒体服务器100和网络控制装置200，通过广播或多播将多个媒体数据分发到具有不同传输速率的媒体接收装置400时，通过将节目控制信息和媒体数据相关联来附加分配优先级 。 附加到程序控制信息的分发优先级被设置为与包括在所涉及的程序中的所有媒体数据的分发优先级相同或更低。 然后，根据分配优先级，传输可能的媒体数据和程序只是有选择地分布。 选择并接收与媒体接收终端装置400仅包含可接收媒体数据的节目有关的节目控制信息。 这样，根据媒体接收装置的传输环境来分配可接收媒体数据。 可以防止媒体接收设备选择无效节目。
