I noticed something odd on Sunday, as I was watching a football game.
First off, I have the latest version of Plex Media Server (v1.20.1.3252-a78fef9a9) installed in a jail on my FreeNAS system. I have a couple of SiliconDust HDHomeRun Extend tuners connected for DVR functionality, and I was streaming to my new 75" TCL television. I enabled DirectStream and MPEG2, as this TV decodes MPEG2 (unlike my other Roku devices). My FreeNAS device uses two aggregated 1 Gbps network connections to a network switch. All of my network switches are interconnected via 10 Gbps fiber but all of the ports are 1 Gbps ports. I say all this because of what I saw on my Plex dashboard:

I’m hoping that my graphic shows up… If not, it shows that the streaming bandwidth is 10 Gbps!!! I wish that were so, but as the TV is connected via 1 Gbps connection and the server is, at best, 2 Gbps, I see no way it is actually streaming at 10 Gbps.
By the way, due to the fact that there is no transcoding taking place between my tuner and my television, and the tuner was reporting a signal strength of 100%, Signal Quality of 98%, and Symbol Quality of 100%, it was an absolutely perfect picture quality. Much better than anything from a cable television provider. I am looking forward to receiving my new SiliconDust ATSC 3.0 tuner and my local stations transmitting in ATSC 3.0 so I can get an HEVC signal instead of MPEG2. Who knows when either thing happens… I’m told the tuner is on a boat headed to Los Angeles but no mention of any stations in our market moving to 3.0.
