Abstract

A display apparatus communicatively coupleable to a multi display system is provided. The display apparatus includes a display; a first connector configured to receive an image from a first display apparatus of the multi display system; a processor configured to perform a control so that a feedback signal that informs of a detection of an error is transmitted to the first display apparatus through the first connector when the error is detected in the received image, a compressed image in which the image is compressed is received from the first display apparatus in response to the feedback signal, and the received compressed image is decompressed to display the decompressed image through the display; and a second connector configured to transmit the compressed image to a second display apparatus of the multi display system.

Claims20

Dependent claims

A display apparatus of a multi display system, the display apparatus comprising:

a display;
a first connector;
a second connector:
and
a processor configured to:
receive an image through the first connector from a first display apparatus of the multi display system,
based on an error being detected in the received image, transmit a feedback signal through the first connector to the first display apparatus,
receive a compressed image, in which the image is compressed through the first connector from the first display apparatus,
decompress the received compressed image,
display the decompressed image through the display, and
transmit the compressed image through the second connector to a second display apparatus of the multi display system,
based on the error not being detected in the received image, identify a bandwidth required for transmitting the image,
identify a difference between the identified bandwidth and a bandwidth of a cable connected to the second connector,
based on the identified difference being smaller than a predetermined value, compress the image received from the first display apparatus and transmit the compressed image to the second display apparatus, and
based on the identified difference being greater than the predetermined value, transmit the image received from the first display apparatus to the second display apparatus.

12 more elements

A method for controlling a display apparatus of a multi display system, the method comprising:

receiving an image from a first display apparatus of the multi display system through a first connector;
based on an error being detected in the received image, transmitting a feedback signal comprising information on a bandwidth of a cable connected to the first connector through the first connector to the first display apparatus;
receiving a compressed image in which the image is compressed based on the bandwidth of the cable from the first display apparatus through the first connector;
decompressing the received compressed image to display the decompressed image and transmitting the compressed image second connector to a second display apparatus of the multi display system through a second connector,
based on the error not being detected in the received image, identifying a bandwidth required for transmitting the image,
identifying a difference between the identified bandwidth and a bandwidth of a cable connected to the second connector,
based on the identified difference being smaller than a predetermined value, compressing the imaqe received from the first display apparatus and transmitting the compressed image to the second display apparatus, and
based on the identified difference being greater than the predetermined value, transmittinq the image received from the first display apparatus to the second display apparatus.
