    HDMI carries both, but since I send HDMI straight to TV, I also then run optical audio out to my receiver so I can run the sound through my system.

    basically..yes..it acts like a splitter..and gives you the ability to use just one cable for both video and audio

    There are two basic types of HDMI receivers - HDMI switching receivers and HDMI repeating receivers.


    A receiver which imploy's a simple switch can't process audio VIA HDMI. The signal is simply looped and no circuitry is actually connected to the HDMI port leading into the receiver.

    An HDMI repeating receiver is connected directly to the HDMI in and therefore can do a number of different functions which are entirely up to the particular manufacture. HDMI repeating receivers can process Audio. Repeaters can also incoporate analog conversion of all signals to HDMI which is sometimes referred to as trans-coding. This allows the user to input all video signals into their AV receiver and have one HDMI cable run to their display. All interlaced signals are converted to 480p.

    The ultimate is HDMI repeating with built in scalers. Again, transcoding of analog signals to HDMI but the receiver can actually scale all signals to 720p/1080i and most recently to 1080p. Some manufactures use high end scalers now such as ABT and Farouja. The results are quite convincing making even standard 480i signals from DVD look incredible when the receiver scales the signal to 720p disiplay.

    HDMI when done properly is an incredible connection but it has had it's growing pains. Most people are oblivous to the potential and continue to connect using the dated component/digital coxial connections. Also note many receivers on the market that use HDMI repeaters can also take advantage of the new TrueHD and DTS MA surround formats when connected to a high rez player that has decoders built into it.
