Your Mr Mute unit must have a clear line of sight to transmit infrared (IR) signals to your TV and entertainment systems just as you do with your hand held infrared clickers.
Through your Mr Mute user interface (UI) you can select your primary and secondary IR protocals for your TV and sound bar. Mr Mute will use your pimary protocal MUTE / UNMUTE signals in its fully automatic operations. The setup in our living room is a Sony TV with a Bose sound bar connected through a fiberoptic cable. So we select Bose as primary and Sony as secondary. We then have an Apple TV connected to the Sony TV HDMI port #1. We have all of our apps installed on the Apple TV platform which we prefer for streaming content delivery. Through the UI you can click the buttons and confirm the Mr Mute unit functions properly. Once confirmed, you can select the channel you are watching. Your TV and your Mr Mute must be watching the same channel. If, for example, you have both MM and your TV tuned to CNN and automatic muting operations is working well then you change your TV to MSNBC you need to also change MM to MSNBC or MM will continue to think your are watching CNN and things will be twisted.
Internet streaming services and the devices recieving streams have inherent delays (latencies) which is very apparent if you have TVs in diffent rooms tuned to the same stream. You may see and hear latency delays of a few seconds and sometimes as much as one minute. In your Mr Mute UI you will see a small screen shot of the streaming content that Mr Mute sees. You should be able to correlate that to what you see on your TV screen. You will realize there is lag either on your TV or on your Mr Mute. This will result in Mr Mute's automatic operation to mute / unmute the sound to be early or late. This mismatch in timing is easily fixed. If Mr Mute is ahead of your TV then enter a delay value into the UI. If your TV image is ahead of Mr Mute continue reading. By pressing the Sony Enter button in my Mr Mute UI my Mr Mute sends the ifrared code to the Sony TV. The Sony TV sees this code coming in its infrared receiver and relays the signal through the HDMI cable using CEC ( Consumer Eletronics Crontrol protocal). The Apple TV receives the Enter button signal on the HDMI and obeys it pausing the streaming content. Now I simply wait a few seconds until the small screen shot on Mr Mute UI matches the paused stream on my TV. Then I press the enter button again and the Apple TV unpauses the show and away we go. The audio video that I am watching on the TV is now exactly synchronized with Mr Mute. And now we enjoy Mr Mute silencing commercials in perfect synchronization all day long on that news feed of our choice. The CEC relay of Mr Mute infared signals to devices comprising my entertainment system is more than covenient. While the Apple TV is the grand master of streaming content I always struggle using the Apple TV clicker with my big fat fingers. The Apple clicker is very touchy and prone to misfires causing frustration. Mr Mute helps to eliminate that problem as all function can occur throught Mr Mute.
