Device and method for controlling OSD protocol

A method of controlling an on-screen display (OSD) protocol in a device, the method comprising,

• receiving analysis data of a video image from an apparatus capable of at least one of wired and wireless communication;
• displaying the video image and the analysis data of the video image on a display of the device;
• determining whether to record the analysis data of the video image in a persistent storage device to be retained after the device reboots or in a temporary storage device to be erased after the device reboots based on a value of a Boolean element “IsPersistentText” added to a parameter format of an open network video interface forum (ONVIF) protocol implemented by the device being true or false;
• and
• storing the analysis data of the video image in one of the persistent storage device and the temporary storage device according to the determination,
• wherein the displaying the video image and the analysis data comprises displaying the analysis data overlaid on the video image,
• wherein, when the analysis data is displayed overlaid on the video image, a user is provided with an interface to select a position of the displayed analysis data with respect to the video image,
• wherein the analysis data comprises image and text, which continuously changes in real time,
• wherein the analysis data of the video image comprises date and time, numbers of checks to be withdrawn, an ATM identification number, an amount, a quantity of the checks, a location, and an image of a face of a user withdrawing the checks,
• wherein the date and the time, the ATM identification number, and the location are classified as data having a first variability based on machine learning,
• wherein the numbers of the checks to be withdrawn, the amount, the quantity of the checks and the face of the user withdrawing the checks are classified as data having a second variability based on the machine learning, the second variability being higher than the first variability, and
• wherein the data having the first variability are recorded in the persistent storage device, and the data having the second variability are recorded in the temporary storage device.
