PIP image reproducing apparatus for image reproducing during firmware upgrade of cable card and image reproducing method using the same
First Claim
1. A method for reproducing an image signal during a firmware upgrade of a cable card of a picture-in-picture (PIP) image reproducing apparatus, the method comprising the steps of:
- determining whether a homing signal for the firmware upgrade of the cable card interferes with reproduction of a first image signal which is displayed on a main screen;
determining whether a second image signal is displayed on an auxiliary screen if receiving the homing signal is determined to interfere with reproduction of the first image signal which is displayed on the main screen;
switching the display of the first image signal to the auxiliary screen and the display of the second image signal to the main screen if the second image signal is determined to be displayed on the auxiliary screen; and
upgrading a firmware of the cable card based on the homing signal.

Abstract
A picture in picture (PIP) image reproducing apparatus and method are provided which is capable of image reproducing during a firmware upgrade of a cable card in which, an image signal that is displayed a main screen is switched to an auxiliary screen if tuning for a homing signal for upgrading the cable card interferes with the reproduction of the image signal that is currently being displayed on the main screen. As a result of switching the image displayed on the main screen to the auxiliary screen, the image can be continuously viewed even while the upgrade of the cable card occurs. In addition, if no image signal is being displayed on the auxiliary screen at the time when the homing signal is received, an input signal may be selected and displayed in the main screen while the image signal which was previously displayed in the main screen is reproduced on the auxiliary screen.

7. A picture-in-picture (PIP) image reproducing apparatus for reproducing a image signal during a firmware upgrade of a cable card, the PIP image reproducing apparatus comprising:
-
a control unit which determines whether receiving a homing signal for the firmware upgrade of the cable card interferes with reproduction of a first image signal, which is displayed on a main screen, and whether a second image signal is displayed on an auxiliary screen;
an input source selecting which selects an input signal for the second image signal if receiving the homing signal is determined to interfere with reproduction of the first image signal and the second image signal is not displayed on the auxiliary screen;
a screen switching unit which switches the display of the first image signal to the auxiliary screen and the display of the second image signal to the main screen if receiving the homing signal is determined to interfere with reception of the first image signal and the second image signal is determined to be displayed on the auxiliary screen; and
a homing processing unit which upgrades a firmware of the cable card based on the homing signal. - View Dependent Claims (8, 9, 10)
