Description

  The present invention relates to a television receiver that displays URL information flowing from a caption.

  In recent years, in television reception, development of a television receiver mounted on a mobile has been active. Regardless of mobile reception, terminals equipped with television receivers are also available for mobile reception. At the end of 2005, one-segment terrestrial digital broadcasting, which broadcasts terrestrial digital broadcasting for mobile reception, is scheduled to start. Digital terrestrial broadcasts not only improve image quality compared to analog broadcasts, but can also receive broadcasts unique to digital broadcasts such as data broadcasts. In digital broadcasting, it is possible to broadcast text broadcasting and subtitle broadcasting in the same way as analog broadcasting.

  Conventionally, closed caption broadcasting is mainly used for people with hearing impairments by using TV sound (announcement, narration, drama dialogue, etc.) as characters, or displaying BGM or drama sound effects as symbols. , The program was better understood and the viewers were entertained. A character string that flows in subtitle broadcasting is not embedded in the screen, unlike a character string that is seen on a general television screen. Subtitle broadcast strings can only be viewed through a dedicated tuner, also called closed captions, which are selectively shown only to those who need them.

  In recent mobile receiver terminals, most terminals are equipped with a browser for using a function for connecting to the Internet. The browser can display a homepage on the Internet by inputting a URL. However, conventionally, when accessing the Internet based on a URL, it has been necessary to input the URL into a browser. For this reason, the terminal user first has to write down the URL known from the broadcast program on paper, start the WWW browser, and input the URL manually.

  In order to solve the above problem, it is now possible to provide a new service by combining subtitles and a browser. For example, there is a system in which URL information is sent to subtitles, and a browser displays a homepage with the URL information. Japanese Patent Application Laid-Open No. 2004-133826 discloses a system that reads the URL information of the caption and displays a homepage.

As described above, in the above conventional example, the URL is extracted from the character on the screen or the character information from the character broadcast, and the WWW browser is activated and registered, so that the user can easily see the URL introduced in the broadcast. It becomes possible.

  However, in the past, since each company developed its own platform, the above invention could not be used.

  The present invention solves the above-mentioned problem. It judges whether or not a browser is installed, reads the URL when it is installed, displays a home page, and displays the URL when the browser is not installed. Providing a display system as it is. As a result, even when a browser is later installed on a terminal that is not equipped with a browser, it is possible to display the URL flowing in the caption without adding a new function.

  In order to achieve this object, the television broadcast receiving terminal of the present invention employs the following configuration. Note that the reference numerals indicate correspondence with the drawings in order to help understanding of the present invention, and do not limit the scope of the present invention.

  According to a second invention, in the first invention, the filtering keyword input by the user is held, the URL character string is compared with the URL before the browser determination unit 12, and the browser determination unit 12 is matched when matched. And a filtering unit 11 that skips the process and moves the processing to the display control unit 15.

  A third invention is characterized in that, in the second invention, the filtering keyword is not input by a user but acquired from an external server through a network.

  According to a fourth aspect, in the first aspect, the browser determines whether or not the data broadcasting is being displayed, and if the browser is displaying or not displaying the process It has the browser state acquisition part 13 to branch.

  According to a fifth aspect, in the first aspect, when the browser determination unit 12 determines that there is no browser, whether to display the URL as it is according to a user setting or to store data in an external memory card A storage switch for determining whether there is an external memory, and an external memory determination unit 19 for detecting that there is no external memory and storing the data in the internal memory 20 It is characterized by.

  According to the first aspect of the present invention, when the URL information acquired from the subtitles is displayed through the browser, the determination unit is provided depending on whether the browser is present or not, so that the respective processes can be branched. As a result, the present invention can be installed in a device not equipped with a browser, and even if a browser is later installed, the URL can be acquired from the browser without requiring a special additional function. The system up to the display of can be used.

  According to the second aspect, when a filtering keyword is input and a URL matching the filtering keyword is acquired, the operation of acquiring the home page by the browser can be skipped, and the operation can be suppressed only to screen display, for example. As a result, browser activation and browser processing can be omitted, and low power consumption can be realized by not wasting the CPU in the receiver terminal.

  According to the third aspect, since the keyword input is acquired from the external server rather than the user via the network, the user does not need to input and the keyword refined on the server side is registered as the filtering keyword. Is possible.

  According to the fourth aspect of the invention, in order to determine whether or not the browser is displaying, if the browser is displaying, the URL is passed to the browser, the home page indicated by the URL is displayed, and the browser is displaying If not, the process can be branched such as displaying as it is or starting the browser again.

  According to the fifth aspect, when a receiver without a browser is used, the URL is displayed on the screen as it is when the user operates the switch, and the external memory is used with the URL as a character string. It becomes possible to store in. As a result, when the URL is stored in the external memory, the user does not need to record the URL. If the external memory is referred to by a device on which the browser is installed and connected to the network, the target homepage is displayed. Can be obtained. In addition, since it automatically determines whether or not the external memory exists and stores it in the internal memory if it does not exist, the user can save the URL information in the internal memory without being aware of whether or not the external memory exists. Is possible.
