I have a question regarding how the pipes should be set up between my AV devices. I'm thinking that this (among other things) might be the cause of some of my woes regarding USBUIRT IR code transmission problems.
I have a media director (zotac zbox AD04) which connects to a Hisense 40" LCD TV via HDMI (video and audio over HDMI). However, I also have a settop box (DSTV Satellite decoder) which feeds into the same TV via the AV1 input (composite video, L, R audio).
So the connections are pretty simple. However, when I set up the TV template, it generates an "embedded" device for every one of the 12 inputs on the TV. This, according to the wiki
, is normal and correct behaviour.
However, how do I connect up the pipes to represent this situation. I want to use AV switching to switch between the STB (settop box) input and LinuxMCE input. There would be, I imagine, two media scenarios:
Scenario 1(default) - The TV is being used as the display for the media director. In this scenario I would like all the commands from my remote control to go the media director (play, pause, right left, ok etc) but preferably the volume+, volume- commands to be blasted through to the TV via the USBUIRT.
Scenario 2(dstv) - The TV to switch inputs to AV1, all the commands from the remote control to go through to the STB via the USBUIRT with the exception of - volume+ and volume- which should go to the TV and, I guess, some sort of custom button on my remote to "exit" this scenario and drop me back to default (which should switch the input on the TV back to HDMI and the Scenario back to default).
When I set things up in the Media Wizard, the Audio and Video pipes of the MD go directly to the HDMI input on the TV, not to the HDMI1 "embedded device" whose outputs also go to the HDMI input on the TV. Is that correct? I haven't added the STB yet, but when I do, should I connect that directly to the AV1 inputs on the TV or should I connect it to the AV1 "embedded device"? If directly to the TV, what is the point of the embedded devices? Do I need them? They're cluttering things up a bit ;-)
Another strange thing that may be related, as described in the other thread, is that after boot of the MD, the first time I press a button on my remote, I'm suspecting that the "power on" command is being sent to the TV. I suspect this because occasionally the TV turns off (toggle mode). So I'm guessing that, knowing that my TV is the display for the media director, the MD, when first being used, is trying to switch on the display. Of course, the display is already on so it ends up switching it off. Is that the default behaviour? Does LMCE track the state of AV devices ito on and off? Obviously with IR control it can't know if the device is switched on or off outside LMCE but I was just wondering....
Any hints, suggestions, tips welcome. This is the first time I'm working through these things.
I've requested the discrete codes for the TV if they're available but at the moment it is Chinese New Year so that's going to take some time ;-)
