Embodiment approach 1
[0127] refer to figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 , Figure 7 , Figure 8 , Figure 9 ,and Figure 10 A non-storage broadcast system according to Embodiment 1 of the present invention will be described.
[0128] like figure 1 As shown, the non-storage broadcast system 100 of Embodiment 1 includes a transmission device 110 , a transmission line 120 , and a non-storage reception device 130 . As will be described later, the non-storage receiving device 130 is called a non-storage type in the sense that it stores a browser but does not store content itself.
[0129] The sending device 110 includes a service attribute storer 111 , a content header granter 112 , a content storer 113 , a content sender 114 , a multiplexer 115 and a sender 116 . A plurality of content storages 113 are respectively provided, and suffixes (small letters) are assigned to each symbol for identification. In the following, when there are multiple of the same co...
Embodiment approach 2
[0200] Below, refer to Figure 11 , Figure 12 , Figure 13 with Figure 14 A non-storage type broadcast system according to Embodiment 2 of the present invention will be described. Such as Figure 11 As shown, the non-storage broadcasting system 700 of this example and figure 1 The shown non-storage broadcast system 100 is the same, and also includes a transmitting device 710 , a transmission line 120 and a non-storage receiving device 730 .
[0201] The transmission device 710 adds an electronic signature 711 to the transmission device 110 of the non-storage broadcast system 100 . The non-storage type receiving device 730 adds a KP extractor 740 , an Sg extractor 741 , and a cryptographic decoder 721 in the non-receiving device 130 . Hereinafter, descriptions of features common to the non-storage broadcast system 100 will be omitted, and features unique to the non-storage broadcast system 700 will be mainly described.
[0202] The electronic signer 711 manages keys f...
Embodiment approach 3
[0228] Next, refer to Figure 15 , Figure 16 , Figure 17 and Figure 18 A storage type broadcast system according to Embodiment 3 of the present invention will be described. like Figure 15 As shown, the non-storage broadcasting system 1000 and figure 1 The shown non-storage broadcast system 100 is the same, and also includes a transmitting device 1010 , a transmission line 120 and a non-storage receiving device 130 . Only the transmission device 1010 replaces the content header granter 110 of the transmission device 110 in the non-storage type broadcast system 100 with the content header granter 112i. Hereinafter, the description of the same features as those of the non-storage broadcast system 100 will be omitted, and the unique features of the non-storage broadcast system will be mainly described.
[0229] The content header granter 112i adds functions described below to the functions of the content header granter 112 . That is, browser content Cbi is specified fo...
