Abstract

PROBLEM TO BE SOLVED: To provide a data distribution system utilizing the Internet that selects a home server to receive a huge amount of reserved data or a portable terminal capable of operation and browsing depending on the situation by placing a home server with a server function to a device such as an INS router existing in each home. SOLUTION: This invention provides stable and efficient information (data) flows by means of organic cooperation between the entire system and each system component by nurturing and developing the concept of 'active view' so as to incorporate a contrivance of the home server to each home and each business office.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a communication router server that operates 24 hours a day in the idle time of the Internet by reserving data by using a program distribution system using the huge Internet such as audio and moving images. This is a system that can be viewed and viewed with a small wireless terminal.

[0002]

2. Description of the Related Art The World Wide Web, which provides images and texts to the world of text-only Internet, has appeared and the Internet has exploded. In addition, the amount of data that flows more and more, not only image data but also audio data and video data, is even greater, and even if the light and infrastructure are strengthened from the wires, the data volume will accelerate further and congestion on the Internet will be inevitable. Especially recently, ADS
Even with the emergence of high-speed lines with L and optical fibers, there is no shortage of time on the net, such as MP3 distribution of movies. Further, even if 1.5 Mbps can be handled in each home, if the permissible capacity of the trunk line is exceeded, the meaning of a high-speed line is lost.

[0003]

A system for systematically exchanging data with a control server that controls the entire Internet and a home server that is provided at the entrance of communication in a home or the like aims to manage the entire infrastructure and increase efficiency. .

[0004]

[Means for Solving the Problems] In the "active view distribution system", the control server, the distribution server, and the child distribution servers scattered in various parts of the country, and the world-level system are not aware of huge audio and video data. A system for distributing by is being considered. However, at this stage, each terminal in the home must be turned on at all times, and it is difficult to store a plurality of huge data in a notebook or portable computer. Therefore, by placing a home server having a server function in, for example, an INS router in each home, it is possible to separate a home server that receives the reserved huge data from a portable terminal that can be operated and browsed. This will realize a huge data distribution system suitable for the coming high-speed network age.

DESCRIPTION OF THE PREFERRED EMBODIMENTS <Overview of System> FIG. 1 shows an overall image in which the present invention is implemented. A program distribution server (1) and a program control server (2) are connected to the Internet (3), and a home server (4) connected to the Internet and a wired or wireless L
It comprises a terminal (5) connected by an AN. The services provided by the present invention include a technique for taking in data in a program distribution server (1) indicated by a time table in a program control server (2) into a home server (4), a home server (4) and a terminal ( This is realized by a technique for displaying or processing data stored in the home server in 5). In the home server (4), a program of a protocol exchanged between the control server (2) and the distribution server (1) is embedded and exchanges data. <Detailed Description of Operation> The home server (4) used in the present invention is an active server that exchanges with the control server (2) and the distribution server (1) by a server OS such as Linx stored on a hard disk at the time of startup. Launch a transfer program. This active transfer program is http (protocol)
Prepares to receive the channel table data and the time table data which are the terminal authentication and the distribution data reading plan with the program control server (2), and make them reside on the home server. The active transfer program is a program control server (2) as shown in FIG.
The current time is obtained from the clock in the server, the clock in the server is adjusted, and the channel table data is received from the program control server. The channel table data is periodically updated to a new table by a timer. The home server enters a standby state waiting for an instruction from the active view program in the terminal (5). When the active view program of the terminal (5) is started, it is displayed as a control panel on the screen of the terminal as shown in FIG. This active view program receives channel table data from the home server by the http (protocol). By pressing the Sch button on the active view control panel in FIG. 3, the channel table data is displayed as a program table as shown in FIG. By selecting a program to be obtained with a mouse or the like, the program is reserved. The information reserved by the active view program is transmitted to the home server and read from the distribution server at the distribution time by the home server's active transfer program. FIG. 9 shows a series of flows in which the home server reads the time table of the channel reserved from the reserved channel, stores the program data in the home server, and displays the data by the active view program. The distribution data stored in the home server is displayed as shown in FIG. 4 by activating the active view program of the terminal and selecting a channel button such as Ch1 in FIG. If a certain channel is reserved, time table data as shown in FIG. 8 is read from the program control server, and Cab is a compressed file for each frame constituting a program.
Files are read in order. The URL specifying the Cab file included in this timetable is distributed and distributed by the child distribution server used in the active view system as shown in FIG. 10, and is most often transmitted from the program control server to the home server as shown in FIG. The URL of the near child distribution server is passed. FIG. 10 shows the data flow of the program control server, the program distribution server, and the home server. FIG. 11 shows the actual arrangement on the Internet. As shown in FIG. 2, the home server itself is a box in which a widely used ISDN router and a server computer are integrated. For communication lines, ISDN, xDSL, optical cables, and the like are compatible with DSU (Digital Service Uni).
t) and a serial port through TA (Terminal Adapter). Since this home server has a router function, the IP address connected through the TA is stored in a NAT (Network Address).
s Translation and IP masquerade to this home server via wired LAN or wireless LAN
Has a function of providing a local IP to a connected computer, and connecting the connected computer to an external Internet and providing data and programs stored in a home server.
After the reserved data is stored in the home server, the data received by the active view program of the terminal (5) can be displayed and browsed at any time.

[0006]

According to the present invention, it is possible to distribute large data by using a conventional mirror server, but since a different URL must be specified or a general-purpose system is not constructed even if the URL is automatically distributed. In order to obtain data from the nearest child distribution server by simply specifying the channel to be obtained by the concept of the distribution channel using this system, The 24-hour home server frees you from the usual server-like usage of terminals. This will reduce the traffic of data on the Internet in the future when large amounts of data come and go, and allow individuals and homes to operate their terminals as if they were home appliances.
