Summary0000816: [BFX-AT100] it take a long time to see Video when hotPlug on a special SEC TV(UN43NU7150). and don't see Resolution on TV Info.
Descriptionhi Kerwin

we had tested with a several SEC TV model for HDMI compatible test in SEC company.
Among of tv happen some issue. so I attach a log.

TV Model : UN43NU7150
TV SW : T-KTM2LAKUC-1202.3
STB SW : v15.513.10

1. when it change a resolution in STB, but didn't be changed in TV info. or don't find any info in TV info.
     I think it is related to TV problem. before asking to SEC company, please check EDID Information in a log.
    Give your comment.

   I give an additional comment more.
   
   first time this TV don't show any resolution via TV info( OSD on TV for information of input source). but after try to do Hotplug at several times, TV info is shown as 1080p suddenly.
   so changed a resolution as order.
   Don't_change_resolution_in_TV_Info.log follow up this order.(1080p --> 1080i --> 720p--> auto --> 2140p.)

2. when it hotplug, (HDMI-> HDMI2), it take 3 sec to see AV .
     Before AV , TV is shown 'no signal'.
     please check EDID information in a log.
     Give your comment.

Thanks

Hi Jason,

(1) Don't_change_resolution_in_TV_info.log
We check log for different resolution changes and don't find anything wrong in the log file.
Each time you change resolution, STB applies that resolution and HDCP also works well.
Please check messages below

We try to figure out what is going on for "first time this TV don't show any resolution..", but there are HDMI related system messages missing in log file.
It is look like these events happened before you insert USB storage and it is not easy to check problem by kernel messages only.

(2)HotPlug_take_a_long_See_Video.log
Before STB send output to TV, HDCP authentication must be done.
From log file, HDCP authentication takes 3sec to be done.
We think it is reasonable time.

BTW, there are also HDMI plug events before USB storage is inserted.
But system related messages are missing.
