Abstract

An electronics system includes a television set and a plurality of external electronic devices connected to the television set. Each of the external electronic devices forms a two-dimensional positive synchronization signal, control codes for controlling the device, and icon data corresponding to the control codes, synthesizes the formed signal, control codes, and icon data with a video signal, and sends the synthesized video signal to the television set. The television set separates the control codes from the video signal, forms a control menu from the control codes, and displays the control menu. A user manipulates a remote controller of the television set to select an item in the control menu. The television set generates a remote control code corresponding to the selected item and sends the remote control code to remote controllers of the external electronic devices, thereby controlling an objective one of the external electronic devices.

Claims

1. An electronics system including at least one first electronic device with a display and at lest one second electronic device connected to the first electronic device,

the second electronic device comprising:

an information adder configured to add a synchronization signal and additional information containing information necessary for controlling the second electronic device to a predetermined area of a video signal to be transmitted to the first electronic device,

the first electronic device comprising;

an extractor configured to extract the additional information from the video signal transmitted from the second electronic device;

a control information provider configured to display, according to the extracted additional information, control information for controlling the second electronic device on the display; and

a forwarder configured to forward a control information piece to the second electronic device once the control information piece is selected by an operator from the control information displayed on the display,

the second electronic device executing a control operation according to the forwarded control information piece.

2. The electronics system of claim 1, wherein the forwarder is configured to forward the selected control information piece to the second electronic device through an infrared remote controller.

3. The electronics system of claim 1, wherein the information adder is configured to search an area of the video signal outside the predetermined area for the same pattern as the synchronization signal, and if the same pattern is found, change the part of the video signal in which the same pattern is found.

4. The electronics system of claim 1, wherein

the additional information added by the information adder includes icon information to be used to control the second electronic device;

and

the control information provider is configured to display icons on the display according to the icon information, the icons serving as the control information.
