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.
