I know that if you open a streaming app on your phone and then cast that video to a Chromecast then the data gets sent directly to the Chromecast. The phone basically sends the Chromecast a link to the video (that's oversimplified, but close enough) so the only data the phone should use is the data needed to load the app and choose what you want to watch, assuming the Roku Express works like a Chromecast. I don't have one so I can't really test it. If the Roku Express is connected to the hotspot, then that would use mobile data on the same way that any Internet consuming device would from the hotspot. Stream quality might not be great though.

Subject: [CODE4LIB] Streaming apps like PBS or live TV

My esteemed listmates,

I've Googled this and like others searches you can get mixed results.

Everyone sounds like an authority on the net.

Would anyone have checked this in the fact-checking world to know if
you download the PBS app (or the live TV app) on to an Android cell
phone to stream a PBS how over to an old TV with an HDMI port (TV
being not 4K but 1080 - think Starsky & Hutch or The Gallant Men! :)
to be received by a Roku Express if any of that uses that Android's
cell phone data?

I understand with live espn you must 1st be a paid scunibrer to some
cable service to strea it to a Roku Express (device) but the I-net in
this case would be provided by a library checked out hotspot.

It's beginning to look a lot like MacGyver.... everywhere you go.

Are sing-alongs allowed on this list?

Or is it like crying in baseball?

Thank you!

Charles.
