Summary0001516: [Smart3][Performance improvement] Delay issue at HDMI_Set_Enable
DescriptionHi kerwin

There is an issue that takes a certain amount of time to call the HDMI_Set_Enable function.
jira is
https://jira.skbroadband.com/browse/BFXBTF-474

Why does the setSourceOutputMode function include usleep(50000)
Please check the JIRA or attachment picture

Does this delay have to be included?
Or please check if you can delete it.

SKB wants to reduce the delay by deleting the code.
Please give us your opinion

Thank you
YK.Jung

Hi YK,

There is no special reason for the 50 ms sleep, it is added as other sys commands.
However, we don't have enough TVs to verify the effect after removing the sleep.

Thank you !

Hi kerwin,

SKB reviewed other manufacturer's code, only EAGLE include usleep code.
Could you share FW (SD/ND) that remove usleep code?
We will test FW on several TV.

Thank you.

Hi Mr. JunGyu Kim,

Do you mean to remove the delay in "displayon" case ?
Should we need to remove it also in "displayoff" ?

Please advise, thank you !

Hi Kerwin

The QA team tested it with 5.3.4A FW and there was no problem.
And in the meeting with SKB yesterday, SKB decided to remove this delay code.
So please apply it in the main branch of Smart3 and UHD4.

And, please put your jira ID in the comment when committing.
Remove delay at HDMI_Set_Enable --> [BFXBTF-474] Remove delay at HDMI_Set_Enable

Thank you
