Description:
RELATED APPLICATIONS 
     This application claims priority to Taiwan Application Serial Number 97148825, filed Dec. 15, 2008, which is herein incorporated by reference. 
     BACKGROUND 
     1. Field of Invention 
     The present invention relates to a control method, system and equipment. More particularly, the present invention relates to a television and a method for operating the same. 
     2. Description of Related Art 
     Nowadays, people usually get their information from a television or a computer, such as a Home Theater Personal Computer (HTPC). Both these two are in the living room. The user only uses either the television or the computer in many cases. When the user watches a television program, he or she may want to know more information or statements about the television program; nevertheless, the user often passively waits for the television program to show something. Even if the television program shows more details, the user may unlike these details; besides, the television program often does not show any further details. 
     Users want to know different kinds of details. For example, if the television program shows a “whale”, a user may want to know the weight of the whale; alternatively, if the television program showed “fireworks celebrating National Day”, the user may want to know the place where the fireworks would be shot off; alternatively, if the user glanced at half of a movie being shown on television, he or she may want to know the time the movie is replayed. 
     In general, the user usually turns on the computer, opens the browser and types keywords to find the answer. However, this procedure is very cumbersome and time-consuming. In view of the foregoing, there is a need in the related field to provide a means for efficiently searching for information played on TV. 
     SUMMARY 
     The following presents a simplified summary of the disclosure in order to provide a basic understanding to the reader. This summary is not an extensive overview of the disclosure and it does not identify key/critical elements of the present invention or delineate the scope of the present invention. Its sole purpose is to present some concepts disclosed herein in a simplified form as a prelude to the more detailed description that is presented later. 
     In one or more aspects, the present disclosure is directed to a television and a method for operating the same. 
     In accordance with an embodiment of the present disclosure, the television comprises a multimedia player, a grabber and a controller. The multimedia player can play information; the grabber can produce at least one word from the information; the controller can control the computer to search for data related to the word. 
     In accordance with another embodiment of the present disclosure, the method for operating the television comprises following steps. When the television plays information, at least one word is produced from the information; then, a computer is controlled to search for data related to the word. 
     Accordingly, if a user watched the television and wanted to inquire information played by the television, he or she can use the television to control the computer to search the related data. 
     Many of the attendant features will be more readily appreciated, as the same becomes better understood by reference to the following detailed description considered in connection with the accompanying drawings.

     For instance, the television can order the computer to search character string; the computer responsive to the television executes its browser to link a search engine and thereby search the character string. As the character string is searched, the computer can send an acknowledgement character to the television; thus, the television can acquire a frame outputted from the computer and show the frame on the screen thereof, where the frame outputted from the computer  190  has result about the searched character string. 
     In  FIG. 2 , the method  200  comprises step  250  and step  250 . In step  250 , the computer is operated via a user interface. 
     In practice the user interface could be a software keyboard, a graphical user interface or a tactile user interface so as to facilitate use. One of ordinary skill in the art will appreciate that the above examples are provided for illustrative purposes only to further explain applications of the present invention and are not meant to limit the present invention in any manner. Other human-machine interfaces may be used as appropriate for a given application. 
     For instance, the television may comprise a remote control; a user can use the remote control to operate the computer after the television shown the frame outputted from the computer on the screen thereof. For example, the arrow keys of the remote control act as the mouse of the computer  190 , and the numeric keys of the remote control act as the keyboard of the computer. Additionally or alternatively, the user interface may comprise a software keyboard, displayed on the screen of the television, for the sake of the input methods of the varied families of languages. 
     For a more complete understanding of step  210  and step  220 , step  210  and step  220  are expounded by reference to the following description considered in  FIG. 3 . 
     Please refer to  FIG. 3 .  FIG. 3  shows a flow chart of sub-steps of the method  200  for operating a television. In one aspect, step  210  comprises sub-step  310 . In sub-step  310 , when the television displays at least one frame, one or more words in the frame are recognized. 
     Furthermore, one or more words are recognized in the frame by means of optical character recognition during sub-step  310 . 
     When the television is used for playing at least one frame of video such as movie, subtitles in the frame are recognized in sub-step  310 ; additionally, the subtitles are divided into various words by means of automatic hyphenation. 
     In another embodiment, the subtitles in the frame are divided into various words according to the hyphenation dictionary during sub-step  310 . 
     For instance, the television may collocate a remote control; if a user watched a frame of the television and wanted to inquire a word in the frame, he or she can use the remote control to operate the television, whereby various words in the frame are recognized in sub-step  310  for ordering the screen of the television to show these words.
