With the development of digital broadcasting technology and the trend of digital convergence, the functions of digital broadcasting receivers are gradually being advanced.
Digital video display devices have a built-in function for using external content (for example, mp3 or jpeg images) in software in the device.
That is, since the external content functions to be provided to the user are determined at the product shipment stage of the video display device, in this case, the user may not have the desired content function embedded in the video display device, which is necessary from the user's point of view. The result is that you pay for missing features.
In addition, the manufacturer of the image display device has a problem in that additional manufacturing costs are required to apply a function that the user does not want in the device, and ultimately the product price of the image display device increases.
Accordingly, in an image display apparatus capable of embedding various functions according to the advancement of technology, a method for properly configuring a content function desired by a user is required.
According to the present invention, in order to allow a user to freely select and execute contents that can be embedded in a video display device, a multi-processor for managing the contents may be distinguished from a processor that is in charge of image processing and audio processing for a broadcast signal. An object of the present invention is to propose a display device and a control method thereof.
An image display device according to an embodiment of the present invention is a processor that processes a broadcast signal received through a tuner and outputs an image or an audio signal through a display unit or a speaker. A first processor controlling an operation; And a second processor that performs IPC (InterProcess Communication) with the first processor, the second processor receiving the application program from the first processor to execute the application program.
In addition, the video display device according to the present embodiment includes a first processor for performing a signal processing so that the broadcast signal is output through the display unit or the speaker of the video display device; And a second processor dependent on the first processor, the second processor communicating with the first processor to execute an application program and output a result of the execution through the display unit or the speaker.
According to another aspect, a method of controlling an image display device includes receiving a content execution request message by a user by a first process; Authenticating the content by the first process, and generating a second process if the content is valid; Forming an IPC connection between the second process and the first process; Transferring the content from the first processor to a second process for execution of the content; And executing the content by the second process.
According to the proposed video display device and its control method, the DTV, which is a video display device, can be variously executed through multi-process after downloading the content requested by the user together with the basic function of receiving and outputting broadcast signals. Therefore, there is an advantage that can provide a video display device suitable for the user's preference.
Hereinafter, with reference to the accompanying drawings for the present embodiment will be described in detail. However, the scope of the idea of the present invention may be determined from the matters disclosed by the present embodiment, and the idea of the invention of the present embodiment may be performed by adding, deleting, or modifying components to the proposed embodiment. It will be said to include variations.
