DISPLAY APPARATUS, HARDWAER UPGRADING APPARATUS, DISPLAY SYSTEM AND DATA PROCESSING METHOD OF THE DISPLAY APPARATUS

摘要

PURPOSE: A display apparatus, an upgrade apparatus, a display system and a data processing method of the display system are provided to fulfill satisfaction of a user, by providing upgrade information, application information and advertisement screen to the user during hub site upgrade as shortening data processing time. CONSTITUTION: First data processors (120,130,190) perform first data processing. Output units (140,195) output the processed data. An external upgrade apparatus (200) including second data processors (220,230,290) performing second data processing is connected to at least one signal connection unit (110). A controller (150) controls the first data processor to process data independently of the second data processor of the connected upgrade apparatus.
