A question about IR reception。。。

First of all, sorry, this is my first post.Not sure about posting format.And,Every sentence comes from Google Translate.
I always have a question,Why the raw data I receive is different every time. Is this situation normal?
`{“value”:1286829195,“protocol”:3,“bits”:32,“hex”:“0x4CB3748B”,"pro

tocol_name":“NEC”,“raw”:"9050,4510,556,578,554,1714,554,578,554,58

0,554,1712,554,1714,552,580,554,578,554,1712,554,578,554,1712,554,

1710,556,578,554,580,554,1710,554,1740,528,578,554,1714,554,1712,5

556,580,552,1712,554,578,554,1712,556,1708,554"}’

548,584,548,1718,528,604,528,1740,548,1714,550"}`
Also, can I use esp8266 to transmit raw data faster than “value"or"hex”?
Hope you can understand what i’m talking about.

The raw is dependent how long you press the button on the remote etc. Nothing to worry about.

In other words, as long as the received RAW data can be used for control, right? ? ?

Don’t use raw to try and control the device, use the decoded values

Okay, I know.Thank you.
