It’s all explained here:

Triple backticks look like this:
```
so if you don’t have this symbol on your keyboard you can simply copy and paste them at the beginning and end of your code.

Please post your sketch here ( property formated with leading and trailing back ticks ) to see what’s wrong and you get error…

How to get the URL http://xmediavn.com/update/1.bin. Where to register or write

That’s the url to the webserver where you’ve put your compiled code (the .bin file).
If you haven’t set-up your own publicly accessible webserver, or haven’t signed-up to a web hosing service that provides a webserver for you to use, then this OTA method probably isn’t for you.
