A TV transmitter, a TV transmitting--method, a TV receiver and a TV receiving method allowing users to find and choose desired programs through the use of a program guide displayed by graphical user interface (GUI). The TV transmitter comprises a signal generation unit for generating text data signals associated with TV broadcast programs and hyper text data signals corresponding to the text data signals, a multiplexer for multiplexing the text data signals and the hyper text data signals onto video signals of the TV broadcast programs to provide a multiplexed TV broadcast signal, and an output unit for outputting the multiplexed TV broadcast signal provided by the multiplexer. The TV receiver comprises a display unit-for receiving and displaying text data signals extracted from a multiplexed TV broadcast signal interleaving the text data signals associated with TV broadcast programs and hyper text data signals corresponding to the text data signals a designation unit for designating any one of the text data signals displayed by the display unit a detection unit for detecting the hyper text data signal corresponding to the text data signal designated by the designation unit and a processing unit for processing the TV broadcast program corresponding to the hyper text data signal detected by the detection unit. |

DETAILED DESCRIPTION It is therefore an object of the present invention to overcome the above-described drawbacks of the related art and to provide a television transmitter, a television transmitting method, a television receiver and a television receiving method allowing users to find and choose desired programs in a fast and reliable manner through the use of a program guide displayed by graphical user interface (GUI).
In carrying out the invention and according to a first aspect thereof, there is provided a television transmitter comprising a signal generation means for generating text data signals associated with television broadcast programs and hyper text data signals corresponding to the text data signals, a multiplex means for multiplexing the text data signals and the hyper text data signals onto video signals of the television broadcast programs to provide a multiplexed television broadcast signal and an output means for outputting the multiplexed television broadcast signal provided by the multiplex means.
According to a second aspect of the invention, there is provided a television transmitting method comprising the steps of generating text data signals associated with television broadcast programs and hyper text data signals corresponding to the text data signals, multiplexing the text data signals and the hyper text data signals onto video signals of the television broadcast programs to provide h multiplexed television broadcast signal and outputting the multiplexed television broadcast signal.
According to a third aspect of the invention, there is provided a television receiver comprising a display means for receiving and displaying text data signals extracted from a multiplexed television broadcast signal interleaving the text data signals associated with television broadcast programs and hyper text data signals corresponding to the text data signals, a designation means for designating any one of the text data signals displayed by the display means, a detection means for detecting the hyper text data signal corresponding to the text data signal designated by the designation means and a processing means for processing the television broadcast program corresponding to the hyper text data signal detected by the detection means
