We propose a
display device that works in conjunction with a
content server using virtual accounts. [Solution] The
system includes a
user input interface that receives login requests for a specific account for viewing content from a
remote control device, a processor that acquires screen information for viewing content based on the login request for the specific account, and a display configured to display a specific screen according to the acquired screen information when
logging in with the specific account. When the processor determines that it has attempted to log in for the first time, the
display device, in conjunction with the control
server, receives a response indicating that the interaction with the specific
content server has been successfully performed by
logging in with the generated virtual account.
