Perfectly connected cable between the Mac and the HDMI cable from the TV. Even if the sound is absent on the tv, the mac was enough for me but to improve it I probably brancherais an audio cable and more later. I could finally watch live on my tv, internet channels that I could not see that in mini format on my computer. After connecting to copy the image on the internet tv, simply to position the hdmi tv channel with remote control. Then on the mac go to Apple menu and then System Preferences, and then monitors provisions and check "copy image". That's it. Voilà! no complaints !!
