Control method of an audio/video system

A display device, comprising:

• a display component;
• a receiver receiving a user command from a control device;
• a first connection port capable of connecting to a peripheral device;
• and
• a processor connected to the display component generating an user interface produced by the display itself to be displayed by the display component, the user interface including a plurality of original options corresponding to the display to be selected by the user command;
• wherein when the first connection port is connected to the peripheral device, the display device receives raw data from the peripheral device, the processor creates a plurality or options in the user interface according to the raw data of peripheral device and automatically integrating the plurality of created options with the original options corresponding to the display in the user interface to produce a single menu in an integrated user interface, generates the single menu in the user integrated interface with the plurality of created options to be displayed by the display component, and generates a first command through the single menu in the integrated user interface for controlling the peripheral device to be transmitted to the peripheral device, the display component being controlled through selection of the original options and the peripheral device being controlled through selection of the plurality of created options;
• wherein the peripheral device comprises at least one A/V input port coupled to a first A/V device and the raw data of the peripheral device comprises data of the first A/V device, and the processor generates a second command for controlling the first A/V device according to the raw data of the peripheral device;
• wherein the display automatically generates a standby command to be transmitted to the first A/V device through the peripheral device when the display detects that a source device other than the peripheral device is selected as the current input source of the display and when the display detects that the peripheral device is not selected as current input source of the display.
