Electronic device and control method thereof

An electronic device providing content, the electronic device comprising:

• a High-Definition Multimedia Interface (HDMI) port configured for communication with an external device, the external device storing first resolution-related information for a first version of HDMI;
• second resolution-related information for a second version of HDMI, the second HDMI version being an upgraded version of the first HDMI version;
• and third information;
• and
• a processor configured to:
• obtain identification information of the external device;
• identify that the third information comprises resolution-related information for the second HDMI version based on the identification information;
• in response to the first resolution-related information and the third information being obtained from the external device, providing the content to the external device based on the third information;
• in response to the first resolution-related information, the second resolution-related information and the third information being obtained from the external device, providing the content to the external device based on at least one of the second resolution-related information and the third information, wherein
• the first resolution-related information is obtained from a first Vendor-Specific Data Block (VSDB) of a memory included in the external device,
• the second resolution-related information is obtained from a second VSDB of the memory, and
• the third information is obtained from an area of the memory other than the first VSDB and the second VSDB.

A method of controlling an electronic device which communicates with an external device through a High-Definition Multimedia Interface (HDMI) port, the external device stores, in a memory, first resolution-related information for a first version of HDMI;

• second resolution-related information for a second version of HDMI, the second HDMI version being an upgraded version of the first HDMI version;
• and third information, wherein the first resolution-related information is stored in a first Vendor-Specific Data Block (VSDB) of the memory, the second resolution-related information is stored in a second VSDB of the memory, and the third information is stored in an area of the memory other than the first VSDB and the second VSDB, the method comprising:
• obtaining identification information of the external device;
• identifying that the third information comprises resolution-related information for the second HDMI version based on the identification information;
• in response to the first resolution-related information and the third information being obtained from the external device, providing content to the external device based on the third information;
• and
• in response to the first resolution-related information, the second resolution-related information and the third information being obtained from the external device, providing the content to the external device based on at least one of the second resolution-related information and the third information, wherein
• the first resolution-related information is obtained from the first Vendor-Specific Data Block (VSDB) of the memory,
• the second resolution-related information is obtained from the second VSDB of the memory, and
• the third information is obtained from the area of the memory other than the first VSDB and the second VSDB.
