If you do go this route, I would strongly recommend that you get a smart TV, with lots of HDMI inputs and streaming ability with Wi-Fi. That way you will not need a switch with a separate remote.
If you want your current TV get an AVR and suck up the 400 page plus manual.
A lot of this comes about because manufacturers will not cooperate. It would be easily possible to give everybody the facilities they want and a manual 20 pages or less and all be controlled from your smart phone and no need for remotes.
Hmm... The reason I don't want to go smart TV, etc is because I'm perfectly happy with my TV. I'm not a big video quality enthusiast. Only thing not satisfactory is number of HDMI ports, which can be cheaply achieved by external switch (~ $50, compared to replacing a TV!).
All I would need is the ability to integrate the switch's remote functionality into a universal remote (which is what I use for one-button control of everything).
To clarify, my present setup is something like this:
Inputs:
DVD/CD player
Cheap local/web media streaming box (WD)
Desktop computer built into HTPC-type box (holdover from earlier that I still like to have for max flexibility)
May add other stuff like a console
AVR: Yamaha x.1
DVD & media streamer connected to this by HDMI for A/V
Computer connected to this by TOSlink for audio
Outputs:
TV with 2 HDMI inputs: 1 receives HDMI out from AVR; other receives HDMI out from computer, through a DVI-HDMI adapter mounted on the video card output
Speakers driven by AVR directly for all audio: Monitor Audio Silvers
Both the computer and the media streamer are connected to a locally placed router by Ethernet wire. The router is also connected to a locally placed NAS box by Ethernet.
Everything is one-button controlled by programming into a Logitech universal remote.
