## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application is a continuation of U.S. application Ser. No. 12/419,929, now U.S. Pat. No. 8,381,256, which is based upon and claims the benefit of priority from Japanese Patent Application No. 2008-169085, filed Jun. 27, 2008, the entire contents of which are incorporated herein by reference.


BACKGROUND
1. Field
One embodiment of the invention relates to a television receiver, a method of controlling the receiver and a network construction device, especially to an improved web server connection function and connecting method.
2. Description of the Related Art
Recent personal computers can readily establish connection to a World Wide Web (WWW) server by way of the Internet. Most personal computers are provided with a browser function so that various types of information can be downloaded from the server and viewed. A WWW server doesn't offer information to a specific country but across the world. For this reason, language content that is attached to moving image content (or still image content) is prepared in different languages. Thus, when access is made from a personal computer to a WWW server to request content, a language request signal (display language request signal) is transmitted. Then, the WWW server analyzes the language request signal to determine the language requested by the user and delivers content in this language.
Recently, most digital television receivers are also provided with an Internet connection function. In a similar manner to the above computer, a digital television receiver of this type needs to transmit a language request signal when requesting content from a WWW server. The receiver, however, has an initial setup function that is to be performed at the time of purchase. The initial setup includes menu language and country settings (see Jpn. Pat. Appln. KOKAI Publication No. 2004-227199, for example). This means that, for the conventional digital television receiver, a language request signal needs to be transmitted to determine a language when accessing the WWW server by way of the Internet, separately from the settings of language and country, which makes the operation irksome.
For the above reason, digital television receivers cause inconvenience to the users. If the content is delivered in a language different from the set-up language when accessing the WWW server, some users may mistake this for a malfunction of the receiver because the initial setup is already completed.

DETAILED DESCRIPTION
Various embodiments according to the invention will be described hereinafter, with reference to the accompanying drawings. An object of the embodiments of the present invention is to offer a television receiver which can automatically maintain consistency between a language that is initially configured and a language of content that is delivered when connected to the web server, a method of controlling such a receiver and a network construction device.
According to one aspect of the present invention, there is provided an apparatus comprising: an initial setup module configured to maintain initial setup information that indicates at least a menu language; a setup information association process module configured to determine a language request signal to request a language the same as the menu language indicated in the initial setup information; and a network control module configured to access a server of the World Wide Web and transmitting the language request signal at the same time to determine a browser language.
FIG. 1 shows an example structure of a television receiver according to the invention.
A tuner 101 receives, for example, a digital broadcast signal, decodes the received signal, and supplies the decoded signal to a transport decoder 102. Video and audio data in packets of a television program selected by the transport decoder 102 is input to an audio-video (AV) decoder 103 and decoded by the decoder 103.
The audio data decoded by the AV decoder 103 is output to a speaker 107, while the video data is output to a display 106. This video data may be combined with video data supplied by an on-screen display (OSD) controller 105 at a combining module 104.
An EEPROM 111 is incorporated to store, for example, programs for implementing the functions of the television receiver and parameters for the programs. A SDRAM 112 is incorporated to temporarily store data in a process of correcting errors in received signals.
A main bus 110 is connected to the transport decoder 102, the AV decoder 103, the OSD controller 105, the EEPROM 111, the SDRAM 112 and the like.
The main bus 110 is connected to a controller 150 that controls the entire receiver. Furthermore, the receiver may be connected to an external device by way of the main bus 110. For this arrangement, the main bus 110 is connected to a net connection module 120, a remote control interface 115 and an ATAPI interface 116. A hard disk drive (HDD) 117 may be connected by way of the interface 116, and a DVD drive 119 may be connected by way of an interface 118.
AV streams divided by the transport stream decoder 102 may be stored in the HDD 117 by way of the ATAPI interface 116. At the time of reproduction, the AV streams read from the HDD 117 are decoded by the AV decoder 103.
The AV decoder 103 reproduces audio and video signals from a transport stream. The decoder 103 also reproduces audio and video signals from DVD-standard audio and video streams. The decoder 103 may be configured to further reproduce audio and video signals from signals of other standards.
An AV encoder 113 is connected to the main bus 110 to convert picture data to a specific format (for example, DVD-standard, transport stream, and baseband) so that the data can be stored in a recording medium. The converted AV information is recorded on a DVD or the like. In other words, the DVD-standard information is recorded on an optical disk by way of the DVD drive 119. The controller 150 controls all the above described blocks (or modules) in a centralized manner. The term “block” or “module” is generally defined as hardware and/or software.
The controller 150 is provided with an initial setup module 155 to make the initial setup of the television receiver. The initial setup includes “country setting” to determine the country in which the receiver is used and “language setting” to determine the menu language.
The controller 150 is also provided with a menu control module 156 to display a menu. The menu control module 156 selects a menu signal for the setup language, and outputs the menu signal by way of the OSD controller 105.
The controller 150 further includes a browser function control module 157. The browser function control module 157 displays the content delivered from the web server on the display 106.
The controller 150 still further includes a setup information association process module 158. The setup information association process module 158 is the main feature of the receiver, associating the initial setup information with the browser function control module 157. This operation will be explained later in detail.
The controller 150 also includes a network control module 159. The network control module 159 accesses a web server 123 connected to the Internet 121, by way of the net connection module 120 in accordance with an address input or address selected by the user. When making the WWW access, the network control module 159 transmits a language request signal, which will be described later.
The controller 150 also includes a remote control command process module 161. The remote control command process module 161 processes a command that is input from the remote controller 124 by way of the remote control interface 115 so that the command is reflected to the operation of a corresponding function of the receiver.
The controller 150 may be further provided with a language content selection module 162. When content of several different languages is supplied from the server, the language content selection module 162 selects, for display, the language content of the language that corresponds to the language request signal.
FIG. 2 shows the screens of the display 106 of a television receiver 100-1. These screens are presented when the user performs an initial setup after purchasing the receiver. After the receiver is switched on, the user manipulates the menu button of the remote controller 124 and selects an item for the initial setup. As a result, Screen A of FIG. 2 appears. The Screen A shows “1. Country setting” and “2. Language Setting”. The user manipulates the cursor key of the remote controller 124 to move the cursor. For example, “1. Country setting” is selected and the enter button is pressed. Then, a list of country names is displayed, although this is not shown in the drawing. The user places the cursor at a target country name and presses the enter button. The country setting is now completed. The display returns to the Screen A, on which the cursor is placed at “2. Language setting”. When the user presses the enter button, items including “1. English”, “2. French”, “3. Spanish”, “4. German” appear, together with a message “select language”, as indicated on Screen B.
When the user places the cursor at “3. Spanish” and presses the enter button, Screen C appears with a message “Language is set to Spanish”. When the “Exit” button is pressed, the language setup is completed, and the screen returns to the main menu.
After the language is configured in the television receiver of the present invention, the setup information association process module 158 automatically sets up a language request signal that is employed by the network control module 159.
More specifically, the setup information association process module 158 determines a language request signal for requesting the same language as the one designated in the initial setup information. Then, the network control module 159 accesses the WWW server by way of the net connection module 120 and transmits the language request signal at the same time in order to determine the language of the browser. The language request signal is transmitted in the head packet when accessing the server 123. In other words, the Accept-Language header of the HTTP request is changed to the description that agrees with the country and language settings.
With the above arrangement of the television receiver, the language request signal required for the Internet access is automatically determined if the menu language is selected at the initial setup. This improves the user's operability, and eliminates the possibility of being mistaken for a malfunction of the receiver.
FIG. 3 illustrates the relationship of the television receiver 100-1, the Internet 121 and the server 123. Language content is prepared, for example, in English, French, Spanish and German in the server 123.
FIG. 4 shows television receivers 100-2 and 100-3, in addition to 100-1, which are connected to the server 123 by way of the Internet 121. In this drawing, because the television receiver 100-1 is set to Spanish, Spanish language content is delivered from the server 123 to this receiver. If the television receivers 100-2 and 100-3 are set to French and English, respectively, the server 123 delivers the language content of French and English individually to the television receivers 100-2 and 100-3.
The invention is not limited to the above embodiment. If the server 123 adopts a method of classifying content by country, the content may be delivered in accordance with the information of “country setting”.
FIG. 5 shows the server 123 distributing content that corresponds to the country setup information configured in each of the television receivers 100-1, 100-2 and 100-3. In other words, the initial setup module 155 stores at least country setup information that is configured as initial setup information. The setup information association process module 158 establishes association with the country setup information, and the network control module 159 accesses the WWW server while transmitting the country setup information.
If the server 123 offers a simultaneous distribution service of multi-lingual content, the receiver may be designed to automatically select language content corresponding to the setup language from the content of various languages.
FIG. 6 shows the server 123 simultaneously distributing multi-lingual content. Each of the receivers can determine and receive the language content selected by the language content selection module 162. When different language content is sent from the server, the language content selection module 162 selects the language content of the language that correspond to the language request signal and adopts the language content for display.
In the above description, the operation of selecting language content is discussed. It should be noted that compressed audio data may be supplied from the server. In such a case, a speech language that corresponds to the selected display language is selected.
FIG. 7 is an example external view of a remote controller. KE1 is a switch for selecting TV, DVD and link mode. KE2 is a power switch, and KE3 are numeric input buttons. KE4 is a button for returning to a previous program, KE5 is a button for selecting an external device input, and KE6 is an analog/digital television switch. KE7 is a button for changing a position of a program or a position on a text page, KE8 is a TV volume change button, and KE9 is a mute setup button. Further, KE10 is an on-screen menu display button, and KE11 is an operation button for exiting the menu. The triangles of KE12 indicate the cursor moving directions, and “OK” is an enter button. KE13 is a button for displaying favorite programs in digital mode, KE14 is a button for displaying a program guide, and KE15 is a text control button. In addition, KE16 is a button for selecting a picture standard from selectable TV standards, KE17 is a button for setting a wide screen, and KE19 is a button for calling up a text service.
FIG. 8 illustrates an example of the menu screen. This menu screen appears when setting up the television receiver. The language used in the menu screen is set by default, for example, to English. When the power switch is operated, “menu language” and “country” appear as a quick setup menu. The user can select a language from English, French or other languages, as the user wishes. For some television receivers, the country may already be configured as a factory default setting. If this is the case, the “country” item would not be highlighted.
According to the above invention, the language for server connection is automatically determined to agree with the language of the menu that is initially set up by the user, which facilitates the operation of the receiver and improves the usability.
