TV and DVD players are connected through cables for transmitting audio/video signals. You may have used S video cables, composite audio/video cables or component cables for HDTV. All these cables transmit audio/video signals in the format of analog, while HDMI cable transmits the signals in digital format so that there’s no need of converting into analog signal at the ends.
An HDMI extender won’t let you miss any detail in your high-definition picture. Extenders are usually connected at the ends of HDMI cables, and they can be used to connect two HDMI cables to create a longer HDMI extension. These extenders function by regenerating the digital audio and high-definition video they obtain from the device source.
