Abstract: The present disclosure includes a communication unit that performs communication with a plurality of display devices and a user terminal and a processor that controls operation related to provision of video content based on the plurality of display devices. The processor may extract corresponding event result information preset in association with code information of a corresponding recognition code when the code information of the corresponding recognition code arranged to track corresponding video content of the plurality of display devices is received from the user terminal through the communication unit, and control the user terminal to display the corresponding event result information through the user terminal that has scanned the corresponding recognition code.

Abstract: A computing device supporting ordered mode journaling. The computing device includes a memory that stores a program for operating a file system supporting ordered mode journaling; and a processor that operates the program stored in the memory. Wherein during execution of the program, when ordered mode journaling for a transaction including one or more files is implemented, the processor stores the transaction in a data area of the memory, and implements the journaling by storing a common journal including metadata of the transaction in a journal area of the memory.
