Abstract

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.

Description

BACKGROUND OF THE INVENTION [0001] The present invention relates to a television transmitter, a television transmitting method, a television receiver and a television receiving method. More particularly, the invention relates to a television transmitter and a television transmitting method whereby a hyper text data signal associated with television broadcast is prepared and transmitted, as well as to a television receiver and a television receiving method whereby the transmitted hyper text data signal is received and processed. [0002] Systems capable of digitally transmitting the television broadcast signal via satellite (broadcasting or communication satellite) to households are getting widespread acceptance. Such systems each offer the household a very large number of TV programs carried illustratively by nearly 80 channels to choose from. [0003] With the ever-growing number of programs they can transmit, these systems propose transmitting along with the programs an electronic pro...
