USB - CEC Adapter

if you own a htpc running windows media center or xbmc then this is a must buy. but make sure your tv has Consumer Electronics Control. (cec. control for hdmi). My set up was htpc connected via hdmi to tv with the cec adapter located between tv and pc. im running a ati hd 7550 witch has dual hdmi out in clone mode. the second hdmi is connected to my amp. which gives me my 5.1 sound. after download the sofware, installing hardware and software. nothing worked software wouldn't run. so managed to find a beta software ([...]) with the new software installed every thing was up and running.plus points. auto switches tv and amp to the right inputs when pc boots. can still use my dual display setup without any problems with the audio side of things. auto powers amp off when pc switches off. xbmc on windows doesn't need any drivers or software.negative points tv doesn't auto switch back to tv when pc switches off.anyway was so impressed i decided to get another one for the bedroom pc but didnt check the spec of the tv no cec. on the bedroom tv. returned to amazon but purchased a raspberry pi installed xbmc using openelec software and to my surprise the raspberry pi has cec built in. top work pulse eight and xbmc.

As expected, it allows me to control xbmc with the smarttv remote control.I use linux and no extra drivers required.

I first learned about CEC by chance - I had a Raspberry Pi with Kodi on it with its own remote control. One day I picked up the TV remote by mistake - and it all worked perfectly. Convinced that the TV couldn't be using telepathy - I learnt about CEC.Wasn't sure how this CEC adaptor would work, but it is very simple - it has three ports - two of which simply intercept the HDMI signal and third port being USB that plugs into the PC.This will only work with TVs that have CEC - unfortunately every manufacturer has given it a different name, for example Samsung's is Anynet+. If you do a web search for "HDMI-CEC Trade Names" to find out the name that your TV's manufacturer has given it and then check that your particular TV has it.Now I can use my Samsung TV remote on Kodi (XBMC) running on an Ubuntu PC. I think it worked straight out of the box, although it is possible I installed the Pulse-Eight CEC add-on from within Kodi. I can't remember - so it must have been very easy!This adapter did seem quite expensive for what it does, but in effect you're paying NOT to have yet another remote!!

An almost complete waste of time. I had no issues with CEC with OpenELEC 4.0.7 on a Raspberry Pi. I bought this item to use with OpenELEC 4.0.7 on a Zotac ZBOX NANO ID18. My experiences to date1. Vendor did not use correct delivery name and address2. Needs separate power USB connection to work3. Reported ejected device, Open Elec locked up4. SSH to Zotac ZBOX, try to reboot, but no response5. Power cycle Zotac ZBOX, which then will not boot due to boot drive corruption6. Fresh install of OpenELEC 4.0.77. Switch off screen, but it gets switched back on a few minutes later8. Use power save feature to try and avoid screen being switched back on9. Problems using AVR volume10. OK, I give up, please refund

I got this to allow Home Assistant on my Linux box to change the channel, volume, and share the remote with Kodi.Didn't really work out. It goes through libcec, pycec, then into Home Assistant, and HA is full of errors about selected device. Doesn't seem to work with that Samsung telly.

CEC is a technology supported by newer TV sets in which IR commands from the TV remote are signaled to a source connected via HDMI to the TV to control that device. Most PC graphic cards with HDMI do not yet support CEC themselves, so you need an adapter like this to use CEC. The adapter will terminate the CEC line on the HDMI cable and convert it to USB. On the PC you then need a driver that supports this. The folks selling this adapter hae written drivers, under linux they are called libcec. They have also integrated libcec into the XBMC media player software (on their web page for version 11.0, on the xbmc.org web page for version 12.0 or later. This adapter works Iflawless with my linux PC running XBMC 12.0 connected to a 2012 Panasonic LCD TV. Panasonic calls CEC "Vierra Connect", and you need to ensure that it is enabled for the HDMI port to which you connect the PC. If you use a port other than HDMI1 on the TV then you need to configure that port number in the XBMC settings for input devices.My PC is actually two floors and ~20 meters away from the Linux-PC with the CEC-USB adapter. I use an inexpensive HDMI-RJ45 extender (http://www.amazon.de/gp/product/B0052R7VKS/ref=oh_details_o04_s00_i00?ie=UTF8&psc=1). As i said it works flawless (using up to 1080p60 video), but i had to go through a few other (actually more expensive) HDMI/RJ45 adapters that did not carry the CEC signal.Pulse EIght has also written CEC support for the Raspberry PI where CEC is supported by the chipset itself, so you do not need a separate CEC-USB adapter for it.CEC itself has one gotcha in tht it is a simple bus. I have connected both the Linux PC with XBMC and the RPI with XBMC to my TV set, but i hve unrelated troubles with the RPI that makes it fail, and then CEC fails even for the Linux PC because CEC is a simple bus (eg: one lane on HDMI connected to all HDMI devices. One device (like my RPI) misbehaving can therefore cause failure for other devices. So i needed to disconnect the RPI to get the Linux PC with the CEC-USB adapter to work. Maybe is different on different TV sets. Not sure.

It work's well, but not all TV has the CEC protocol implemented or hasn't the CEC protocol completely implemented. I tested in Samsung and LG.
