Program guide signal receiver and method thereof

A program guide signal receiver employed in a device for receiving a digital broadcasting satellite (DBS) signal which includes a program guide signal which includes information identifying a plurality of programs and a digital video signal including the plurality of programs, said program guide signal receiver comprising:

• a controller to generate a first signal for selecting the program guide signal included in the DBS signal and a second signal for selecting one of the plurality of programs included in the digital video signal and identified by the program guide signal, in response to inputting certain key signals;
• a decoder to decode said program guide signal selected in response to said first signal and to output a decoded program guide signal;
• a storing unit to separate and store the information included in said decoded program guide signal, wherein the information includes video data;
• a compressing unit to compress the digital video signal corresponding to the program selected according to said second signal, and to selectively compress the video data stored in said storing unit when the digital video signal corresponding to the program selected according to said second signal is not present within the digital video signal of the DBS signal;
• a mixer to mix said decoded program guide signal as a main screen signal, with one of said digital video signal corresponding to the program selected according to said second signal and compressed by said compressing unit and said video data stored in said storing unit and selectively compressed by said compressing unit, as a sub-screen signal;
• and
• a display to display said main screen signal and said sub-screen signal.

A program guide signal receiver for use in a device for receiving a TV signal including a first plurality of programs and a digital broadcasting satellite (DBS) signal including a program guide signal including information identifying programs of at least one of the first plurality of programs and a second plurality of programs and a digital video signal including the second plurality of programs, said receiver comprising:

• a controlling unit to generate a first signal for selecting the program guide signal included in the DBS signal and a second signal for selecting a program from one of the first and second plurality of programs included in the TV signal and the digital video signal, respectively, in response to inputting certain key signals;
• a decoder to decode the program guide signal in response to said first signal and to output a decoded program guide signal;
• a storing unit to separate and store the information included in said decoded program guide signal, wherein said information includes video data;
• a compressing unit to compress one of the first plurality of programs of the TV signal which corresponds to the program selected based on said second signal, to compress one of the second plurality of programs of the digital video signal which corresponds to the program selected based on said second signal, and to compress the video data stored in said storing unit when the program corresponding to said second signal is not present in the TV signal or the digital video signal;
• a mixer to mix said decoded program guide signal as a main screen signal with the one of the TV signal, the digital video signal, and said video data stored in said storing unit, which corresponds to said second signal and which is selectively compressed by said compressing unit, as a sub-screen signal;
• and
• a display to display said signals mixed by said mixer.

A method for operating a program guide signal receiver employed in a device for receiving a TV signal including a first plurality of programs and a digital broadcasting satellite (DBS) signal including a program guide signal including information identifying the first plurality of programs and a second plurality of programs and a digital video signal including the second plurality of programs, said method comprising the steps of:

• generating a first signal for selecting the program guide signal included in the DBS signal;
• generating a second signal for selecting a program from one of the first and second plurality of programs included in the TV signal and the digital video signal, respectively, in response to inputting certain key signals;
• decoding the program guide signal in response to said first signal and outputting a decoded program guide signal;
• separating and storing the information included in said decoded program guide signal, wherein said information includes video data;
• compressing one of (i) one of the first plurality of programs of the TV signal which corresponds to the program selected based on said second signal, (ii) one of the second plurality of programs of the digital video signal which corresponds to the program selected based on said second signal, and (iii) said video data stored in said storing unit when a program corresponding to said second signal is not present in the TV signal or the digital video signal;
• mixing said decoded program guide signal as a main screen signal with said one of the TV signal, the digital video signal, and said video data stored in said storing unit, which corresponds to said second signal and which is selectively compressed by said compressing unit, as a sub-screen signal;
• and
• displaying said signals mixed by said mixer.
