  FIG. 2 shows a configuration example of the access log shown in FIG. In the access log 31, an access log is recorded every time the website is accessed. One access log is a GET including the “use side IP address” of the user device that requested access, the “Web side IP address” of the Web site that is the access destination, and the URI (Uniform Resource Identifier) used for the access. The instruction content “resource” is stored in association with each other. In the example of this figure, as the use side IP address, the use side IP address “192.168.1.1” of the home gateway 30a, the web side IP address “1.1.1.1” of the website, and the contents “GET” used for access “ "GETindex.html HTTP / 1.1" is recorded.

  In addition, although the description based on the IPv4 standard is normally used for the IP address, it may be expressed based on the IPv6 standard as shown.

  FIG. 3 shows a configuration example of the preference determination table shown in FIG. The contents of the preference determination table 52 are set or updated every time an access log is received in the profile server. Access logs are received every Web access, every number of access logs, or every regular time. In the preference determination table 52, an identifier of a home gateway and a video content identifier corresponding to a preference category for each user device are stored in association with each other. A MAC (Media Access Control) address may be used as the home gateway identifier.

  In the example of this figure, the identifier of the home gateway 30a is “00: 00: 00: 00: 00: 01”, and the video content identifier “000001” corresponding to the preference category “movie” is set correspondingly. ing.

  FIG. 4 shows a processing procedure in the first embodiment. This processing procedure is executed in cooperation with the home gateway 30, the profile server 50, and the video distribution server 60.

  First, the home gateway 30 monitors the Web access of a PC and a server in the Internet and acquires an access log (step S11). Access from a PC to a website on the Internet is performed by transmitting a request URI to the Internet via the home gateway 30 and returning a response from the server of the website to the PC via the gateway 30. At that time, the home gateway 30 monitors only requests from the relaying PC. From this request, the PC IP address is the PC side IP address, the Web site server IP address is the WAN side IP address, and the request URI is recorded in the access log as a resource.

  In general, traffic from the Internet to a PC is higher than traffic in the reverse direction. Therefore, it is not preferable to monitor the response from the Internet to the PC, and only the traffic from the PC to the Internet is monitored. As a result, the CPU occupancy rate and memory usage of the home gateway 30 can be reduced, and a decrease in throughput can be avoided.

  Next, the home gateway 30 transmits the access log acquired in step S11 to the profile server 50 (step S12). The timing of transmission may be every Web access on the PC, every fixed number of access logs, or every regular time. The access log once transmitted to the profile server 50 is normally deleted from the home gateway 30.

  Next, the profile server 50 performs preference analysis on the access log from the home gateway 30 to determine a preference category (step S13). A video content identifier corresponding to the determined preference category is set in the determination table for the user device. The method of preference analysis is, for example, by actually accessing the website recorded in the access log to obtain a homepage, and by counting the frequency of keywords corresponding to the preference category for the character examples on the homepage, It is conceivable to determine the preference category of the Web site.

  Next, the home gateway 30 acquires a video content identifier from the profile server 50 (step S14). The timing for acquiring the video content identifier may be, for example, when the television receiver connected to the home gateway 30 is turned on or when a channel is selected. Next, the home gateway 30 requests video content distribution by transmitting a video content distribution request together with the video content identifier to the video distribution server 60 (step S15). In response to this, the video distribution server 60 transmits the video content corresponding to the video content identifier to the home gateway 30 (step S16). The video content is played back to the viewer on the television receiver.

  Reference is made to FIG. 7 for an example of a video content playback screen. Here, the screen 1 is divided into a plurality of frames 2 and 3, in which normal video content corresponding to the viewer's channel selection is displayed in the frame 2. In frame 3, video content based on preference analysis is displayed. In this example, as a result of the preference analysis, the video content of the movie advertisement CM belonging to the preference category “movie” is broadcast.

  In the first embodiment, since the home gateway 30 and the profile server 50 cooperate to automatically analyze the viewer's preference, a CM or the like adapted to the preference without setting the viewer's own preference. Video content can be viewed. Furthermore, a mode is realized in which a viewer views a sub-content such as a CM that is played in parallel with a part of the screen while selectively viewing the specific video content as the main video content.

<Second embodiment>
FIG. 5 shows the overall configuration of the second embodiment. Here, a user device 100c is shown instead of the user device 100a in the first embodiment. The user device 100 c includes a broadband router 70 connected to the Internet 10, a PC 40 c and a set top box 80 connected to the broadband router 70, and a television receiver 90 is connected to the set top box 80. Other configurations are the same as those of the first embodiment.

  The broadband router 70 has an IP network connection function for a PC or a set top box. The set-top box 80 has a function of receiving a video stream from a WAN or CATV network via the broadband router 70 and supplying a video signal and an audio signal to the television receiver 90, and further, an HDD or a recordable DVD. It may have a video recording function using. The broadband router 70 has a function of monitoring the web access of the connected PC 40c and acquiring the access log 31c as a web access record, accompanying the IP network connection function. In the access log 31c, a request URI issued from the PC 40c is recorded.

  FIG. 6 shows a processing procedure in the second embodiment. The processing procedure is executed in cooperation with the broadband router 70, the set top box 80, the profile server 50, and the video distribution server 60.

  First, the broadband router 70 and the set top box 80 share the identifier (step S21). This is because the web access is monitored only by the home gateway in the first embodiment, whereas in the second embodiment, the broadband router 70 only monitors the web access, and the video content is received. This is because the identification is performed for each user device including the broadband router 70 and the set-top box 80 since it is performed by the set-top box 80. Such setting is normally set manually in advance. As a method of sharing the identifier, it is conceivable to use a masquerading function that makes the global address assigned to the broadband router 70 appear as the address of the set top box.

  Next, the broadband router 70 monitors the web access of the PC and the server in the Internet and acquires an access log (step S22). Access from a PC to a website on the Internet is performed by transmitting a request URI to the Internet via the broadband router 70 and returning a response from the server of the website to the PC via the gateway 30. At that time, the broadband router 70 monitors only requests from the relaying PC. From this request, the PC IP address is the PC side IP address, the Web site server IP address is the WAN side IP address, and the request URI is recorded in the access log as a resource.

  Next, the broadband router 70 transmits the access log acquired in step S22 to the profile server 50 (step S23). It is conceivable that the transmission timing is every Web access on the PC, every fixed number of access logs, or every regular time. The access log once transmitted to the profile server 50 is normally deleted from the broadband router 70.

  Next, the profile server 50 performs a preference analysis on the access log from the broadband router 70 to determine a preference category (step S24). A video content identifier corresponding to the determined preference category is set in the determination table for the user device. The method of preference analysis is, for example, by actually accessing the website recorded in the access log to obtain a homepage, and by counting the frequency of keywords corresponding to the preference category for the character examples on the homepage, It is conceivable to determine the preference category of the Web site.

  Next, the set top box 80 acquires a video content identifier from the profile server 50 (step S25). The timing for acquiring the video content identifier may be, for example, when the television receiver connected to the set top box 80 is turned on or when a channel is selected. Next, the set-top box 80 requests video content distribution by transmitting a video content distribution request together with the video content identifier to the video distribution server 60 (step S26). In response to this, the video distribution server 60 transmits the video content corresponding to the video content identifier to the set-top box 80 (step S27). The video content is played back to the viewer on the television receiver.

  In the second embodiment described above, since the broadband router and the profile server 50 automatically analyze the user's preference from the user's web access, the user does not set his / her preference. Video content tailored to the user's preference can be distributed to a playback device such as a television receiver via a set top box.

  In the second embodiment, the method in which the broadband router and the set-top box share the identifier is manually set by the user. However, the present invention can be applied even when the broadband router and the set-top box automatically share the identifier. Applicable.

  In the above-described embodiments, the apparatus for performing web access on the Internet has been described as a personal computer (PC). However, other apparatuses such as game machines and internet televisions may be used as long as they are web-accessible devices. It may be a device.
