The HDMI cable is a data transmitter for high-resolution devices such as televisions, video games and computers. The connector simultaneously transmits high-quality video and audio, for example, a PlayStation 3 and an LCD television, ensuring excellent resolution and sound with 5.1 channel support and other variations. If you are already thinking about retiring your high definition device to the arrival of this new component know that you are wrong, it is not a new plug, but a feature present on any HDMI cable.

The CEC (Consumer Electronics Control) refers to an independent synchronization property between devices independent of the transmission medium. Probably you already use it on your TV without knowing what it is or the next time you look for another device, pay attetion to this.
