Program switching device and method
First Claim
1. A program switching apparatus comprising:
- receiving means for receiving a signal of a broadcast program;
static image output means for freezing and temporarily outputting as a static image an image of said broadcast program;
a switcher for selectively switching between an output of said receiving means and an output of said static image output means;
control means for controlling said switcher, said static image output means and said receiving means so as to output said static image for a predetermined duration, after which the output of said static image is switched to said broadcast program signal received by said receiving means;
selection screen output means for selecting and displaying a selection screen having button icons corresponding to a plurality of programs as a window superimposed on said image of said broadcast program; and
operating means for moving a cursor among said button icons on said selection screen and for selecting a program designated by said cursor,wherein said control means controls said receiving means to receive a program designated by said cursor while said cursor is moved on said selection screen by said operating means before a program is selected by said operating means, thereby receiving said program designated by said cursor before said program is selected for quickly switching to said selected program.

Abstract
A program switching device and a method thereof which can prevent a disorder of images and an invisible state of the image when a channel (program) is switched. When it is instructed to switch a program to the other program in the state where the image of a program of a predetermined channel is displayed, at step SP111, the image of the program currently received is converted into a static image to mute the sound. Then, at step SP212, the receiving processing of channel is started after switching. At step SP113, the process waits until the processing of channel switching is terminated, and when it is terminated, the static image set at step SP111 and the mute are released at step SP114.

8. A program switching apparatus comprising:
-
receiving means for receiving a signal of a broadcast program; static image output means for freezing and temporarily outputting as a static image an image of said broadcast program; a switcher for selectively switching between the output of said receiving means and said static image output means; control means for controlling said switcher, said static image output means and said receiving means so as to output said static image for a predetermined duration, after which the output of said static image is switched to said broadcast program signal received by said receiving means; selection screen output means for selecting and displaying a selection screen having button icons corresponding to a plurality of programs as a window superimposed on said image of said broadcast program; and operating means for moving a cursor among said button icons on said selection screen and for selecting a program designated by said cursor, wherein said control means controls said receiving means to receive a program designated by said cursor while said cursor is moved on said selection screen by said operating means before a program is selected by said operating means, thereby receiving said program designated by said cursor before said program is selected for quickly making the switching to said selected program, and further wherein said static image output means mutes a sound signal when said static image is output, and said static image output means relieves the mute of said sound signal when said static image output is relieved.
