I’ve been using the iOS betas for about a week and a half now and as far as picture goes everything seemed fine. Now, I’ve mainly been watching TV shows with minimal movement, or at least movement that was not as quick as sports. However tonight I decided to watch some of the Red Sox game through the latest beta on my iPhone to see how the experience was. I immediately noticed what I can only describe as dropped frames, which causes the picture to look like it’s been frozen ever so briefly. It happens every few seconds but is very noticeable in 60fps sports. The channel I was watching on is NESN which is a 1080i signal, so I thought perhaps it was something to do with using the blend deinterlacer, so I changed it to linear. Same issue. I then remembered that ESPN (720p) is also carrying the game tonight so I tried that, thinking maybe it’s a deinterlacing issue in general, but it happens there too. The feels like it happens not quite as frequently on the 720p channel vs. the 1080i channel, but it’s close.
I went over to both my Apple TVs and turned the game on them both through the current release of the Channels tvOS app and it was perfect. No frame skipping. Then just to cover another base (no pun intended) I power cycled my HDHR Prime. No difference. I then stood right next to my wireless access point (Ubiquiti AC-Lite) and still had the issue. I rebooted the access point and router but still have the issue. For the record I’m connecting to my access point via the 5 GHz AC network. My Apple TVs are connected to my network via Ethernet, but just for testing purposes I put them on the AC wireless network and there is no frame dropping like I see with the iOS app.
Having said all that, I haven’t seen any other reports of this, and so I’m wondering if this is something that anyone else is seeing (again, look at a sports broadcast)? Devs, is this any kind of issue you’re aware of?
If needed I should be able to capture this happening using my lightning to HDMI adapter but will need to see where I stashed it tomorrow.
Edit: I should add that I’m using an iPhone 6s running iOS 9.3.3. An additional troubleshooting step was power cycling the phone.
