    VieraLink

    Warning: long post ahead.

    This is somewhat related to my other thread about Blu-Ray players.

    The way our TV is currently set up is quite complicated for people who don't know what they're doing (I do since I installed it all, but my parents can't remember to save their life )

    Basically, we have 3 HDMI-using devices - a Blu-Ray player of some kind (TBD), a cable box (Scientific Atlanta model, the kind most companies use), and my Xbox 360.

    These 3 things are hooked into an Onkyo receiver which has a total of 4 HDMI inputs - each one has been configured with its own settings etc. and then it plugs into the TV via HDMI1.

    Sadly, our model receiver won't convert component to HDMI, so for the Wii, it's plugged directly into the TV.

    Now, our receiver has an imitation VieraLink built into it (I think it's called HDMI Smart Mode or something like that, can't remember) - and effectively what that means is that when we turn the TV on or off, the receiver also turns on or off - and when I adjust the TV's volume, it passes that onto the receiver. Makes it much easier since we have too many remotes and they're all programmed for the TV. In addition, I've disabled the TV's built in speaker to avoid confusion, so because the TV thinks it has a VieraLink receiver, it will just pass volume commands on to the receiver.

    So in order to fix the problem of the Wii, I have an optical SPDIF cable coming from the TV's "audio out" jack to the receiver's "TV in" jack, and it's smart enough to know (again, emulation VieraLink) that if it's changed to a non-HDMI input, to use the TV in.

    Now, when I replaced the PS3 with the Samsung Blu-Ray player, which has its own form of VieraLink emulation, I discovered something really interesting and useful. If the TV is on HDMI1 like it should be, and if the receiver is set to something else such as the cable box or Xbox, if the player is turned on, it automatically switches the receiver to the Blu-Ray source.

    What would be really useful, and effectively eliminate the need to use the receiver's remote at all (because hey, ideally I want my family to just be able to turn the TV on, then grab the remote of whatever device they're using, UNLESS they're using the Wii, but that hardly ever happens), is if I could somehow get something that does the same VieraLink cloning so that when the cable box is turned on, it kicks the receiver over to cable and so on.

    Is there such a thing?

    The other thing I considered was one of those auto-sensing HDMI switches, but those are expensive and not as useful in this case, because I have different settings (the Blu-Ray player is set to Dolby Pro Logic Movie, the Xbox is on DPL Game, and the cable box is on something similar, I think I just have direct pass-through so it doesn't upscale the 5.1 to 7.1) and that would mean only using one input on the receiver, with virtually no way to change it yourself if the switch malfunctions and isn't showing the right source.

    What sort of options do I have?

    VieraLink is just Panasonic's trade name for the HDMI CEC standard - each manufacturer seems to have their own name for it, Samsung calls it Anynet+, Sony calls it BRAVIA Link/Sync, etc...

    Technically, they're all supposed to be work with each other, so for example, you could use your Samsung TV's remote control to control the PS3, and devices would turn on/switch sources like you described.

    To get your cable box to do the same, it also has to conform to the HDMI CEC standard, but this doesn't seem to be popular on anything other than TVs, Blu-ray players and receivers.

    Probably a universal programmable remote, say from the Logitech Harmony range, might be the only way to get it all happening at the press of a button.

      Wait, so I can use a standard IR remote to control the PS3 if I use CEC? Though, my PS3 is a first-generation model (I previously had the third-generation, which I sold and bought a used CECHA01 instead so I can play PS2 games)... which means it won't work anyway.

      At this point I'm going to just permanently replace the PS3 with a settop Blu-Ray player, since the PS3 is a bit confusing for my parents (I disabled auto-start since I don't want it starting automatically for games and so on, of course the caveat is now movies don't auto-start either)

      As for the cable box, hm. A quick search shows this:
      Slideshow: Inside Panasonic’s Booth at CES 2009 - Cable Box with HDMI-CEC - CE Pro
      But that's from 2009 and I can't seem to find any info about the actual box itself. My cable company is pretty nice in that we can use our own purchased cable boxes (and just use their CableCard with it - in fact, it's cheaper that way, since we have to pay to rent the box opposed to just the CableCard)
      Do you know of any other cable boxes that comply with that standard? Supposedly the ones Comcast's XFINITY uses do, as their forum mentions it as well. The box we have is really outdated, I'm surprised it even *has* an HDMI port.

      But I guess what I wanted to know is if it were possible to someone add HDMI CEC to a device that doesn't already have it. Obviously I can't control my cable box with a remote other than the cable box (Save for a universal remote), but in theory, couldn't some third-party device detect if you turn the device on (as in, the HDMI cable starts outputting a signal) and basically send a CEC signal to the receiver saying "yeah, it's turned on, switch to it" and vice versa for turning it off?
      It sounds simple in theory, but of course somebody would have to actually make such a device.

      I don't even care if it breaks HDCP, as I mentioned the cable box is really old so it doesn't really even use HDCP.

      And what about the Xbox 360? I'm assuming that has no way of using HDMI-CEC either.

        I think there are IR to CEC boxes, although Logitech do have their own Bluetooth adapter to allow their universal remotes to control the PS3.

        Don't know of a device that emulates CEC features or add them to devices that don't support it. The Xbox 360, as far as I know, does not support CEC.

          Hm, I just had a thought.

          I know they make HDMI switches that use CEC - do those also *output* CEC as well?
          In other words, if I just have one device plugged into it, it would "switch" to that device when I turn it on, but would it send a CEC signal to the receiver as well?

          Something like this:
          For only $33.60 each when QTY 50+ purchased - 4x1 HDMI® Switch w/ CEC Engine (Full 1080p HD) w/ 3D support | Auto & Powered HDMI Switches

            The device you plug into it would still have to support CEC, as it's the device that I think sends the CEC signals to the rest of your connected devices (this switch merely passes on or replicate the signal, as I know some switches will block CEC signals).

              Ah, OK. I will have to look for a cable box with CEC, then.

              The setup is perfect with the Blu-Ray player... it will automatically turn the TV on, set it to HDMI1, and set the receiver to Blu-Ray if it isn't already - perfect for one-touch movie watching for my parents.

              If only they made cable boxes that will do the same...
