August 6, 2014



By a News Reporter-Staff News Editor at Electronics Newsweekly -- A patent by the inventor Park, Jae-hong (Seoul, KR), filed on December 17, 2012, was published online on July 22, 2014, according to news reporting originating from Alexandria, Virginia, by VerticalNews correspondents.

Patent number 8786783 is assigned to Samsung Electronics Co., Ltd. (Suwon Si, KR).

The following quote was obtained by the news editors from the background information supplied by the inventors: "The present inventive concept relates to a display apparatus and an external peripheral device connected thereto, and more particularly to a display apparatus connected to an external peripheral device providing a feature that is not supported by the display apparatus.

"Generally, televisions (TVs) have a function of receiving and playing broadcast signals. With rapid technological advancement, hardware of audio-video (AV) devices, such as TVs, is upgraded at a fast pace, and expansion or addition of new features in software tend to continue. However, once a user purchases an expensive display apparatus, such as a TV, the user may not use upgraded features with the display apparatus until it is replaced by a new device, for example, for 5 to 7 years.

"A conventional TV cannot perform functions of playing videos, receiving and executing game images from different image sources, or retrieving and displaying information in real time through a network such as the Internet, which are realized by an up-to-date device, such as a smart television."

In addition to the background information obtained for this patent, VerticalNews journalists also obtained the inventor's summary information for this patent: "Accordingly, one or more exemplary embodiments provide a display apparatus which is capable of displaying a graphic signal using an external peripheral device, and an image displaying method thereof, wherein the graphic signal is associated with contents of a video signal and displayed along with the video signal.

"Further, one or more exemplary embodiments also provide a display apparatus which determines a kind of an image input from an external peripheral device and displays the image, and an image displaying method thereof.

"In accordance with an aspect of an exemplary embodiment, there is provided a display apparatus including: a display which displays an image; an external peripheral device; a peripheral device interface connected to the external peripheral device; an image composing module which combines a video signal with a graphic signal and outputs a combined signal to the display; and a controller which outputs a graphic signal to the image composing module when the graphic signal is input from the external peripheral device through the peripheral device interface, the graphic signal being associated with contents of a video signal displayed on the display and displayed along with the video signal.

"The display apparatus may further include a video processor which processes a video signal, wherein the controller outputs a video signal to the video processor when the video signal is input through the peripheral device interface.

"The display apparatus may further include a user interface which receives a selection by a user, wherein the controller outputs a control signal to the external peripheral device so that the graphic signal provided from the external peripheral device is output to the image composing module when a selection signal to display the desired graphic signal is received through the user interface.

"The graphic signal provided from the external peripheral device may include transparency information.

"The peripheral device interface may include a USB port and an HDMI port.

"The external peripheral device may be connectable to a network and receives data through the network.

"In accordance with an aspect of another exemplary embodiment, there is provided a display apparatus including: a display displaying an image; an external peripheral device; a peripheral device interface connected to the external peripheral device; a video processor which processes a video signal; an image composing module which combines the video signal with a graphic signal associated with contents of the video signal and displayed together with the video signal, and outputs a combined signal to the display; and a controller which determines whether an image signal received through the peripheral device interface is the graphic signal, outputs the graphic signal to the image composing module when the image signal is the graphic signal, and outputs the video signal to the video processor when the image signal is the video signal.

"In accordance with an aspect of another exemplary embodiment, there is provided an image displaying method of a display apparatus including a peripheral device interface connected to an external peripheral device and a display, the image displaying method includes: receiving a graphic signal associated with contents of a video signal displayed on the display and displayed along with the video signal from the external peripheral device through the peripheral device interface; combining the graphic signal with the video signal; and displaying the video signal and the graphic signal on the display.

"The image displaying method may further include receiving a video signal through the peripheral device interface; and processing and displaying the received video signal on the display.

"The display apparatus may further include a user interface which receives a selection by a user, and the method may further include receiving a selection signal to display the desired graphic signal through the user interface; outputting a control signal to the external peripheral device so that the graphic signal provided from the external peripheral device is output to an image composing module.

"In accordance with an aspect of another exemplary embodiment, there is provided an image displaying method of a display apparatus including a peripheral device interface connected to an external peripheral device and a display, the image displaying method including: receiving an image signal through the peripheral device interface; determining whether the image signal is a graphic signal associated with contents of a video signal displayed on the display and displayed together with the video signal; and combining an input graphic signal with the video signal when the image signal is the graphic signal or processing a video signal when the image signal is the video signal, and displaying the signal on the display."
