Possible to use USB TV tuner and hdmi pass through at the same time?

This may be irrelevant, but I have a question about the TV tuner. I understand that you plug the tuner into the XB1 through USB, not HDMI. I have an Xbox 360 hooked up to my XB1 through the HDMI-in port. In order to play 360 games, I have to use the TV app,
and the TV tuner uses the TV app as well in order to work. I also understand that when you plug in the TV tuner, the OneGuide separates the TV tuner channels from the "HDMI content". My question is this: if I have a TV tuner with a coax cable connected through
the XB1's USB port AND an Xbox 360 connected through the XB1'S HDMI-in port (both at the same time), can I switch between my Xbox 360 and my TV tuner when using the TV app? Thanks for the help!

Hi Don,

Unfortunately I don't think that is a compatible set up for Live TV on the Xbox One because Video output or input is through HDMI so the Xbox will not be able to get any video without an HDMI output from a cable box or if you have the official Xbox One USB
TV Tuner. There is no way to input the built in tuner's details manually to get a picture through IR, it must be through HDMI or the Xbox USB TV Tuner.

The support articles I provided before states all of that information and also describes the best way to connect home theater systems and unfortunately IR video output is not possible on the Xbox.

it needs to be tuned on a pc via tv tuner card or a cable box. your tv probably also has a tuner built into it.

at this time there hasnt been any information about how a pc will work with the hdmi pass through. but it will probably require an usb ir adapter for a universal remote which can be controlled by the kinect ir blaster. i really cant see it working any other
way. though i dont really understand how the cable box pass through works either.

my tv outputs the video audio via hdmi to the av receiver via Panasonics ARC connection , ive tried connecting the ARC HDMI out from tv to xbox in but it still cant see the video feed ? would this possibly be a driver issue within the xbox ? I have reported
the issue on the xbox insider program but have had no feedback as yet .

would it be possible to manually add the tuner as a Panasonic tuner within the set up ? or is it just simply impossible without an external tuner or Microsoft usb tv tuner ?

It's a Microsoft USB tv tuner specifically for the Xbox. The aerial goes into it and then it gets plugged into the Xbox. The tv is connected to the HDMI output.
