Benefits of technology

[0007] In view of the foregoing, an object of this invention is to provide a program receiver and a method of display processing of program explanation screen with a simple configuration which can provide, when recording and reproducing the received program explanation information, a reproduced program explanation screen as high-definite as the received program explanation screen.
[0008] The foregoing object and other objects of the invention have been achieved by the provision of a program receiver and a method of display processing of a program explanation screen in which unrelated and unnecessary information is not displayed in reproduction when program explanation screen generating means for generating a received program explanation screen based on program explanation information added to the received program data is employed to generate a reproduced program explanation screen based on program explanation screen added to the reproduced data. This enables efficient graphics processing and helps the user distinguish the received program explanation screen from the reproduced program explanation screen and prevents confusion.

Problems solved by technology

This problem complicates the process and prevents high-definition digital recording.

Embodiment Construction

[0018] Preferred embodiments of the present invention will be described with reference to the accompanying drawings:

[0019] Referring to FIG. 1, a digital data recording / reproduction system 1 is shown as a whole, which is configured by an antenna 2, an IRD 3 as a program receiver of the present invention, an institute of electrical and electronics engineers (IEEE) 1394 cable 4, and a digital video tape recorder (hereinafter referred to as digital VTR) 5.

[0020] The digital data recording / reproduction system 1, in a reception mode where received program data is decoded in real time and directly displayed on a monitor 15, receives broadcast waves from communications satellites (not shown) via the antenna 2 and sends the waves to a tuner 7 of a receiving selector 80 in the IRD 3. In the IRD 3, each circuit operates according to the control by the CPU 6 and a received signal S1 from a transponder selected by the tuner 7 is sent to a front end 8.

[0021] The front end 8 demodulates the re...

Abstract

In a program receiver and a method of display processing of a program explanation screen, it is possible to display a reproduced program explanation screen as high-definite as a received program explanation screen when reproducing received program explanation information after recorded. Unrelated and unnecessary information is not displayed in reproduction when program explanation screen generating means for generating a received program explanation screen based on program explanation information added to the received program data is employed to generate a reproduced program explanation screen based on program explanation information added to the reproduced data. This enables efficient graphics processing and helps the user distinguish the received program explanation screen from the reproduced program explanation screen to prevent confusion.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application is a continuation of U.S. application Ser. No. 09 / 438,630 filed on Nov. 12, 1999, the disclosure of which is incorporated herein by reference.BACKGROUND OF THE INVENTION [0002] The present invention relates to a program receiver and a method of display processing of a program explanation screen, and more particularly, is suitably applied to a receiver / decoder in a digital satellite broadcasting system. DESCRIPTION OF THE RELATED ART [0003] In digital satellite broadcast systems which have provided hundreds of programs to users, broadcast waves from the transponder of a communications satellite are received via a receiver / decoder (hereinafter referred to as integrated receiver decoder (IRD)) and program data of a selected channel is decoded so that the image and voice are outputted from a monitor. [0004] The IRD receives program explanation information that explains the contents of programs, as well as program data of di...
