US 6,806,913 B2 · Apparatus and method for processing additional information in data broadcast system

Abstract

In an apparatus and method for processing a data broadcast signal, additional information contained in a TV broadcast signal can be easily selected and acquired without a time limit by using a still picture. Additional information corresponding to the still picture from additional information transmitted in real time with a moving picture broadcast program is processed, and the additional information is stored, together with still picture information matched with the additional information, so that an object of the additional information included in the moving picture or a picture swiftly changing can be accurately selected from the still picture without a time limit. As a result, additional information corresponding to the selected object is easily acquired. In addition, additional information can be easily searched using still pictures corresponding to additional information stored in a memory.

Dependent claims

A method of processing additional information included in a broadcast signal in a data broadcast system, the method comprising the steps of:

(a) determining whether the additional information exists in a broadcast signal currently being received, and displaying on a screen an additional information reception display image corresponding to a result of the determination;
(b) determining whether an additional information acquisition command is inputted while a picture including the additional information is displayed on the screen;
(c) editing at least a still picture and an additional information picture on one screen, thereby generating an additional information guide screen, when it is determined that the additional information acquisition command is inputted in step (b), the still picture being obtained at a time when the additional information acquisition command is inputted, the additional information picture corresponding to an object selected from the still picture;
and
(d) performing additional information processing corresponding to a command input through the additional information guide screen.
