In order to achieve the above object, a software upgrade method of a broadcast receiver having at least two controllers, the method comprising: receiving software of a control means transmitted in the same radio wave format as a broadcast signal through a specific channel for a period designated by a broadcast station; Downloading, by a controller, a software download subject, from the controller, software included in a broadcast signal; Determining whether the downloaded software is related to itself and other controllers, and upgrading its own driving software or transmitting the same to the corresponding controllers; And upgrading, by the controller receiving the software, its own driving software using the software.
The association determination may include comparing an ID included in the software with an ID of each control unit;
The method may further include comparing version information included in the software with version information of each controller driving software.

Therefore, according to the present invention, since all the control means can be upgraded by software in an image device having two or more control means, the overall function and performance of the image device can be always optimized.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention that can specifically realize the above object will be described.

1 and 2, an embodiment of a software upgrade apparatus and method of an imaging apparatus according to the present invention will be described.

As an embodiment of a software upgrade apparatus for an imaging apparatus according to the present invention, a configuration of a digital TV having two control means is shown in FIG. 1.

That is, the digital broadcast signal processing unit 10 for receiving a digital broadcast signal and performing image processing through demodulation and decoding, and the image processing for displaying the signal processed by the digital broadcast processing unit 10 on the screen. An image processor 20 is included.

First, the digital broadcast signal processor 10 includes a digital tuner 11, a signal processor 12, a first memory 13, and a first controller 14.

The digital tuner 11 receives a broadcast signal.

The signal processor 12 performs the above-described demodulation and decoding process on the received broadcast signal.

The first memory unit 13 stores driving software of the first control unit 14.

The first control unit 14 downloads the software included in the broadcast signal, determines the association with itself and the second control unit 27, and upgrades the driving software stored in the first memory unit 13 according to the determination result. Or transmit the software to the second control unit 27.
