Therefore, if the arrival delay s due to network delay occurs, different URLs may be assigned to two users who access at exactly the same time. Furthermore, when the information server allocates a specific URL at a certain time, even if the user sends a request after the time, the URL is past and cannot be allocated. Therefore, it becomes impossible for the user to obtain the information of the specific URL.
- the information server device processes the requests that have arrived first in order. Therefore, if a request of a user who accesses later and has a low network delay arrives earlier than a request of a user who accesses first and has a large network delay, the URL is preferentially assigned to the latter. That is, it is difficult to process an access request in the order exactly according to the time when the user issued the access request.

- each client terminal makes an inquiry at random time so that many client terminal subsystems 1300 do not access the time server all at once. Should be done. It is also desirable to divide the NTP server settings by region when setting channels. This prevents access from being concentrated on the same server.
- the address created by the address creation unit 1316 can be stored in the address storage unit 1322. In this way, if you want to obtain content synchronized with the broadcast from the network, you can access the server later rather than at the same time as the broadcast.
- the address storage unit 1322 receives the instruction from the user input unit 1315, and stores the address including the time information created by the address creation unit 1316. Later, upon receiving an instruction from the user interface of the user input unit 1315, the information transmitting / receiving unit 1318 transmits the address information stored in the address storage unit 1322 from the network interface 1319, and is specified by the address information. Receive content. Receiving The displayed content is displayed by the browser 1320 and the display unit 1321. Also, when the display of the display unit 1321 switches from the display of the browser 1320 to the display of the broadcast video, the information storage unit 1332 was previously displayed by the browser 1320. The information is stored for each broadcast channel of the display source.

- the control flow branches as follows according to the result of the determination processing in step S1342. That is, the pressed button is the channel selection button 3 2 4 (in the example shown in FIG. 3, the number buttons are 0 to 9, but in many cases, the buttons are number buttons such as 1 and 12 corresponding to the channel. ), "Linked display” button, "Recent access” button, "Later net” button, select Z If the button is for playback recorded video, the control is step S1 3 4 3 and S1 3 4 6 respectively. Proceed to, S1351, S1353, S13554. The appearance of the remote controller used in this embodiment is shown in FIG.
- Steps S 1 3 4 3 and subsequent steps are processing for changing channels.
- a switching signal is normally sent to the tuner to switch the received video.
- the base address stored in the base address storage section 1314 is changed. For example, for a video that is already recorded on a hard disk VTR or the like, the recorded video is selected instead of switching to a tuner.
- step S1345 a timer indicating the actual time when the broadcast wave channel is selected is selected. If only the real-time broadcast is selected, this step is not necessary because the timer always indicates the current time. If the device switches between playback of recorded media and display of the current broadcast, this step uses the real-time timer if reception of real-time broadcast waves is selected. When playback of the media is selected, set the initial value of the timer of the media. After step S1345, the control returns to step S1341.
- Steps S 1 3 4 6 and below are the processing when the “linked display” button is pressed.
- the “linked display” button is a button prepared to display content linked to broadcasting with one touch.
- step S1346 an address with time is created. However, it is possible to set not to create a timed address. In this case, only the base address is prepared here.
- the address with time is 'And the time read from the timer. Additional information such as pre-stored area information may be added.
- the address may be created after determining whether to add time information for each channel. This is effective when accessing a server that does not have a mechanism to determine the time.
- a station that operates only a relatively small server such as a local station, a CS (Communications Satellite) broadcasting station, an Internet stream service station, and the like. It is desirable that the information for determining whether or not to add the time is retained along with the base address until the next setting change.
- a relatively small server such as a local station, a CS (Communications Satellite) broadcasting station, an Internet stream service station, and the like.
- step S1347 the created address information is transmitted to the Sarno rule.
- address information is sent to the server indicated by the URL.
- protocols such as TCPZIP (Transmission C 0 ntr 0 1 P rotocol, P internet Protocol) and H TTP (Hypertext Transfer Protocol) are used. Any layer may be used with any protocol as long as the combination allows communication between the server and the client, and the type is not limited.
- step S1348 the content corresponding to the address created in step S1346 is transmitted from the server, and is received.
- step S1349 the content received in step S1348 is analyzed and analyzed to display the content.
- the content is often described in a language such as HTML (HyperT ext Ma rkup Language), but it is described in a programming language that can be executed by a web browser. It does not matter.
- HTML HyperT ext Ma rkup Language
- Commact HTML is often used for content description.
- step S1350 a determination is made as to what kind of button input has been made by the user. If the pressed button is a “channel” button for switching broadcast programs, control proceeds to step S1343. As a result, the channel is changed, and the display is switched to the video. If the button pressed is the “Back” button, the display returns to the previously selected channel. If the button input corresponding to the instruction to switch from the currently displayed content to another content display is performed, the process proceeds to step S1347, and the base address is updated to the switched base address. . In a normal web page, when an address is expressed in the form of a link, select it with an arrow button, etc., and press the "OK" button to send a new address, and receive the corresponding content. , indicate.
- the client terminal may display the content that has been acquired and stored during the processing from step S1346 to step S1348. Then, the user can view the content from when the “linked display” button is pressed until the information is displayed.
- a timed address is created periodically, and the content related to the broadcast being displayed is periodically acquired in advance, and the acquired content is displayed during access to the server device. You may. In this case, the user can view the content that is related to the currently displayed broadcast content and that is close in time. Of course, if the content acquired at the time of pressing the “linked display” button is the same as the content requested by the user, the user can immediately watch the desired content.
- step S1351 'display the recently accessed address. If there is a timed address in the most recently accessed one, it is also displayed.
- step S1352 the user selects one of the addresses displayed in the list. It is usually realized by menu-type display and input using arrows and a decision button. Thereafter, the control proceeds to step S1347, in which the same processing as when the "link display" button is pressed is performed.
- step S1353 when the "NET" button is pressed, only the address is stored while the current image is displayed.
- the address memorized here should be displayed along with the title of the recently accessed address in the list that appears when you press the "Recently accessed” button. Or, it is memorized in "net later” Alternatively, only the list of addresses may be displayed as a list.
- step S1354 processing when the "recorded video selection / playback" button is pressed is executed.
- This process is implemented only for devices that can handle videos stored in the past. This part is not necessary for those that have only a tuner such as a normal TV and can handle only video that is distributed in real time. For example, on a hard disk VTR or the like, the date and time of recording and the channel can be stored, so this processing can be implemented.
- step S1354 the base address is changed using the channel information stored in association with the recorded video.
- the base address may be set by a person.
- the recording start time and the current playback time The time at which it was broadcast (recorded) is derived from the appropriate position and set to the timer. In other words, in the case of recorded data, the timer is set so that the time when it was actually broadcast can be reproduced.
- the base address may be stored directly. In the case of DVD, etc., it is possible to input the address by the user and to send the relative time from the start to the server as information with the playback start time of DVD set to zero.
- DVD, hard disk VTR, etc. the time axis of the content such as play, stop, fast forward, etc. can be operated. Of course, in these devices, the timer that generates the timed address changes the time following such an operation.
- the processing shown in this flowchart handles the interface with the user, and In order to play the role of analyzing and analyzing the content downloaded from the server, it is often compiled in the form of a browser. Its main functions are: channel switching management, server access, address generation and management, and user interface.

- the four main dog modes are the "Recent Access Address Display” mode, which displays recent access. Recent accesses are also displayed in list form, selected with arrow buttons 354 and 356, and determined by "OK” button 350. When any of the recent access destinations is selected, the state becomes the web display state 1 365 5.
- FIG. 43 shows a flowchart of a process performed in such a modification in place of step S1353 in FIG.
- step S1371 it is determined whether or not the pressed button is a "net later” button 344. If the “net later” button 3 4 4 has not been pressed, this processing ends. Otherwise, control proceeds to step S1372.
- step S1372 access is made to an address including time and other information to obtain content.
- step S1373 the title of the content is extracted from the content obtained in step S1372, and stored together with the address of the corresponding content.
- the title is written between the tag “ku tit 1 e>” and the tag ⁇ Z tit 1 e>. There are many.
- the client extracts this part and stores it as title information. This title will be used later when the user tries to access the stored content, as shown in Figure 38.
- step S1374 the received data is cached in temporary storage. Later, when the user tries to access the content, the content can be read from the temporary storage to reduce the network access time.
- Figure 44 shows an example of display on the video display screen. Downloading content takes time. If the screen is switched immediately after sending a request for content, nothing may be displayed on the display screen for a while. Therefore, it is desirable to switch from the video to the web page after all or part of the page content can be acquired and the display data of the page can be constructed. However, even in that case, Time lag may be reported from pressing the "Display" button 3 4 6 to switching the screen o
- a display indicating that there is special live information is performed in the lower right area 2 14 of the video display screen 210.
- This display is usually sent from a broadcasting system. For example, in quiz applications and online shopping, accessing the web now may provide special information. In such cases, it is important to inform the user.
- This information can be transmitted both analog and digital. For example, in analog broadcasting, it is conceivable to send this information superimposed on the video. In digital broadcasting, this broadcast can be sent as digital data. Alternatively, this digital data information may be obtained from a server different from the broadcast content server. It is also possible for the client terminal to access the server and automatically cache data.
- These displays need not be characters but may be symbols such as icons. However, it is desirable that the meaning be a symbol that can be understood by the user.
- the user watching the broadcast in real time may access the server at once.
- the processing capacity of the network or the server is low, the response of the server may become extremely slow, and sufficient service may not be provided. Therefore, it is effective to provide the client terminal with a mechanism that prevents the access from being flooded every time when the access is made by the “linked display” button by the user, either in the case of automatic access.
- This can be, for example, a request for automatic access as described above, This can be realized by a process of actually performing transmission after waiting for a random time after an input occurs. It is desirable that the maximum value of this waiting time is realized between 0 and 60 seconds.

- the purchased services differ for each user.
- Some broadcasts have age restrictions. For broadcasts with these restrictions, it is desirable to restrict access to related information (web access).
- web access if there is a broadcast channel that can only be received by a specific user due to parental control, a function that prevents other users from seeing all or part of the corresponding web content is implemented. Is preferred. Therefore, in each of the above-described embodiments, if there is a live access, it is conceivable to replace the process of responding to the live access with the process shown in FIG.
- step S1381 it is determined whether the access restriction is imposed on the currently broadcast channel (or package media such as DVD). For example, in a CS tuner, this can be determined from the contract information stored by each tuner and the information of the channel currently being viewed.
- step S1382 it is determined whether or not access restriction is provided on the broadcast side. If there is an access restriction, control proceeds to step S1383, otherwise control proceeds to step S13853.
- step S1383 it is determined whether or not the client terminal is permitted to access the broadcast by comparing the information on the client terminal with the condition of the access restriction on the broadcast side. If access is allowed, control proceeds to step S1385, otherwise control proceeds to step S1384. In step S1384, since this client terminal does not have the access right to the content, the user is notified of this. This may be displayed directly on the client terminal or by accessing a special address if you do not have access rights and displaying information from the server. Display a message and end this process.
- step S1385 the client Access to the content on the web is displayed because the last access is allowed.
