Device and method for controlling OSD protocol

1. 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wherein the analysis data of the video image comprises date and time, numbers of checks to be withdrawn, an ATM identification number, an amount, a quantity of the checks, a location, and an image of a face of a user withdrawing the checks,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wherein the numbers of the checks to be withdrawn, the amount, the quantity of the checks and the face of the user withdrawing the checks are classified as data having a second variability based on the machine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.

2. The method of claim 1 , wherein the temporary storage device comprises a random access memory (RAM).

3. The method of claim 1 , wherein the persistent storage device comprises at least one of a flash memory, a hard disk drive, and a NAND memory.

4. The method of claim 1 , wherein the analysis data of the video image comprises at least one of:

data about a number of persons counted in the video image;

information about a vehicle number recognized in the video image;

information about a vehicle in the video image;

information about a location, a date, and a time of capturing the video image;

information about one of a credit card and a note in the video image captured at a point of sale (PoS);

billing information; and

Internet of things (IoT) data of an object.

5. The method of claim 1 , wherein, when at least one portion of the analysis data is displayed overlaid on the video image, the user is provided with an interface to select a position of each of the at least one portion of the analysis data with respect to the video image.

6. The method of claim 1 , wherein, when at least one portion of the analysis data is displayed overlaid on the video image, a first portion of the analysis data that is recorded in the persistent storage device is displayed at a predetermined position, and a second portion of the analysis data that is recorded in the temporary storage device is displayed at a position selected by a user by using an interface to select the position of the second portion of the analysis data with respect to the video image.

7. The method of claim 1 , wherein the displaying the video image and the analysis data comprises displaying the analysis data as one of an image and text.

8. The method of claim 1 , further comprising, in response to the analysis data of the video image relating to a number of persons counted in the video image, transmitting an alarm message when the number of persons counted in the video image exceeds a threshold value.

9. The method of claim 1 , wherein the analysis data of the video image is received from an external apparatus capable of one of wired and wireless communication.

10. The method of claim 1 , wherein the determining is performed based on a user input.

11. The method of claim 1 , wherein the determining further comprises determining to record a first portion of the analysis data of the video image in the persistent storage device, and to record a second portion of the analysis data of the video image in the temporary storage device; and

wherein the storing further comprises storing the first portion of the analysis data of the video image in the persistent storage device and the second portion of the analysis data of the video image in the temporary storage device.
