Roku: Signal Strength vs Signal Quality

Post by KBishop26 » Wed Aug 07, 2019 1:52 pm

Can someone explain the difference. I get 100% on the signal strength but only like 65% on the signal quality. If it drops below like 55% the HD Homerun drops out and goes back to the Beta home screen.

Really wish there was a software fix or work around to stop the Homerun from going back to the home screen. It’s particularly a problem since signal quality can bounce around from 65 to 70 to 55 in just a matter of seconds. I’d accept some small pixelation instead of the Homerun going back to home screen.

If you ever see 100% strength with poor signal quality, most likely your signals are too strong, and suggest attenuating the signal down bit so you can see the real strength.

The nature of the roku player is very poor for tv for many reasons, including not being able to handle errors in the stream that most other hardware would ignore.

Signal quality is a measure of how clear a signal is, while strength is how powerful it is. If you think of it like listening to a radio broadcast, quality is whether you can hear the music/talk/whatever over any static, while strength is how loud it is. You need a minimum level of strength to be able to understand it, and going any louder than that won't make a difference. On the other hand, if the signal just isn't clear, turning up the volume won't make it any easier to understand, just louder.

The Roku app has almost no control over the Roku video player. It can give it a URL to access a video and tell it to start and stop playing, and that's about it. Anything after that is internal to the player, and Roku's player is not tolerant of issues in the stream, and usually just gives up if something is too damaged for it to play. On open platforms like iOS and Android, we can (and do) replace the built in player with one of our own that supports things better, but Roku is completely locked down and there is no alternative.
