## Background
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.
