Hi Jerry

I checked the excel result file
but there is a difference between AAC/AC3 ( the previous measurement unit was dbfs at mantis id = 1560 , ATV10 )
Anyway please check why there is a difference from AC3/AAC in this test result.

Thank you

Hi YK,
I compared the volume table of ATV10 and ATV12. I found no problems.
Our QA judged that this may be caused by network lag during the stream.
From the test results , it seems that the AAC codec output of ATV12 and ATV10 is slightly inconsistent.
Can you ask Amlogic about this ?

Hi Jerry

I have to submit this data to SKB.
and if there's an issue , I need to explain the cause.

If it is assumed that there is a network issue, please measure it again.
And you said that the output of the AAC codec is inconsistent, what is the basis for saying that?

Thank you
YK.Jung

Hi YK,
Sorry , I learned this morning that our QA colleague got Covid-19.
He needs to stay at home. I will ask hime to help me test again at work next week.
QA will reconfirm whether the problem is caused by test network lag.
The booking time is February 20th.

And you said that the output of the AAC codec is inconsistent, what is the basis for saying that?
--> Based on the test result of AC3 codec is similar to that of ATV10.

Hi YK,
The following pictures are QA's tests for volume level 20 AAC files.
QA tested 5 times. The results of these tests were close.
At the same time, they also tested the network situation and
found that the network disconnection will cause a slight error in the average data.

You can refer to the video file.
