1. A display apparatus comprising:
- a display unit which displays an image thereon;
a first image processor which processes an image signal;
a first central processor which controls the display unit and the first image processor; and
a first controller which selectively grants a control right to one of the first central processor and an upgrading apparatus, which processes the image signal and upgrades the display apparatus, to control the display apparatus,wherein the first controller grants the control right to the upgrading apparatus to perform a predetermined control operation corresponding to a predetermined event by using a second central processor when the upgrading apparatus is connected to the display apparatus via a connector which is provided in the display apparatus, andwherein, when the upgrading apparatus is connected to the display apparatus via the connector, the display apparatus outputs the image signal, via the connector, to the upgrading apparatus having the control right as a subject operates, receives the image signal processed by a second image processor of the upgrading apparatus, the second image processor comprising a decoder and the received image signal being decoded by the decoder, and displays an image on the display unit based on the image signal processed by the second image processor, wherein the second image processor is controlled by the second central processor.

16. A control method which is executable by a display apparatus, comprising:
-
connecting to an upgrading apparatus which processes an image signal and upgrades the display apparatus; granting a control right to one of a first central processor of the display apparatus and the upgrading apparatus to enable control of the display apparatus; and performing a predetermined control operation corresponding to a predetermined event by using the one of the first central processor and the upgrading apparatus to which the control right is granted, wherein the granting the control right comprises granting the control right to the upgrading apparatus to perform the predetermined control operation corresponding to the predetermined event by using a second central processor when the upgrading apparatus is connected to the display apparatus, and wherein the performing the predetermined control operation comprises outputting the image signal from the display apparatus to the upgrading apparatus having the control right as a subject operates, receiving the image signal processed by a second image processor of the upgrading apparatus by the display apparatus, the second image processor comprising a decoder and the received image signal being decoded by the decoder, and displaying an image on a display unit provided in the display apparatus based on the image signal processed by the second image processor. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25)
