[0045] Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. (1) First Embodiment (1-1) Overall Configuration

[0046] refer to figure 1 , reference numeral 1 denotes an entire information distribution system in which a distribution center 4 having a program distribution server 2 and a program control server 3 is connected to the Internet 5 as an information transmission network.

[0047] Such as figure 2 As shown, the program distribution server 2 will divide a plurality of channels based on the first split time (in this case, one hour), the first, second, third and fourth channels CH1, CH2, CH3 and CH4 The unit program data (D1-20, D1-21...D1-19), (D2-20, D2-21...D2-19), (D3-20, D3-21...D3-19) and ( D4-20, D4-21...D4-19) are stored in the program database 2XA as distribution information INF.

[0048] The distribution information is generated by program production terminal 8 connected to Internet 5 and store...

no. 3 example

[0134] Referring to the description of the third embodiment Figure 21 , where with Figure 19 The same reference numerals denote corresponding parts, the information distribution system 1X has a distribution center 4 located in Japan, and program information data is distributed from the main program distribution server 2X to Japanese user terminals 6JPA through the Japanese Internet 5JP under the control of the program control server 3 , 6JPB...

[0135] In addition, the program control server 3 in the distribution center 4 connected to the Japanese Internet 5JP controls the additional distribution server 2NA distributed in North America through the North American Internet 5NA connected to the Japanese Internet 5JP with the intercontinental transmission line 15A, thereby passing through the Japanese Internet 5JP, intercontinental The inter-transmission line 15A and the North American Internet 5NA distribute the program information data of the main program distribution server...

no. 4 example

[0140] The fourth embodiment is described with reference to the Figure 22 , where with Figure 19 The same reference numerals designate corresponding parts, and the moving picture data VD is transmitted from the moving picture data generating device 21 to the main program distribution server 2X of the distribution center 4 .

[0141] The moving picture data generating device 21 converts the video signal S1 corresponding to the image of the subject picked up by the television camera 21A into a digital signal, then compresses it with the encoding device 21B, and transmits the result as moving picture data VD.

[0142] In the case of this embodiment, the main program distribution server 2X generates unit program data DM-N having 5-minute moving picture data VD as program frame content data Dmnp, and uses the program frame content data Dmnp as live mode program information via the Internet 5 The data is sequentially distributed to the additional distribution servers 2A, 2B...2E....

Abstract

Program information is readily distributed to user terminals. An information distribution system wherein channel table data CHDAT and timetable data TMDAT are distributed under control of a program control server (3) to user terminals (6A, 6B,...) through a transmission line (4), program segment content data Dmnp included in the timetable data TMDAT is designated by each of the user terminals (6A, 6B,...), and the program segment content data Dmnp is distributed to the user terminals (6A, 6B,...), thereby distributing program information of the same content simultaneously to the user terminals (6A, 6B,...).

Description

technical field [0001] The present invention relates to an information distribution system, more specifically, it is suitable for distributing information through an information transmission network, such as the Internet. Background technique [0002] Conventionally, in order to provide homepage information through the Internet, a homepage is created on a WWW (World Wide Web) server in the Internet. [0003] As an information distribution server for hypertext multimedia data, World Wide Web (WWW) servers store server software called HTTP (Hypertext Transfer Protocol) and hypertext information expressed in a description language called HTML (Hypertext Markup Language) , thereby establishing a link to information in its own database or other databases having information address data called URL (Uniform Resource Locator) contained in link information called a link point. [0004] In a conventional World Wide Web (WWW) server, based on information addr...
