    I am curious about the icon highlighted in this photo. I have searched the 5000T manual and cannot find a reference to it. It is on the C4 programme Great British Car Journeys.

    Sorry the photo is not displayed, I don't know how to do that.

    I think it's to indicate that the broadcast is in Dolby Digital. Either that or there is alternative commentary/information available if connected to the internet.
    Edit. The second one is more likely.
    2nd edit. Almost certain it's not the first one, lol.
    3rd edit. See Graham's answer below

    5.1 Surround sound audio

    Freeview-HD uses AAC audio (Not AC3- aka Dolby Digital)

    No Dolby Digital on Freeview-HD. It uses the advanced audio codec as it simplifies the Audio description delivery. AAC can handle AD and 2.0/5.1 wthin the same audio stream. Audio description on Freesat-HD requires a seperate MP2 audio track plus the main DD2.0 or 5.1 track

    AAC is converted to DD on the digital audio outputs on Freeview-HD kit.

    OK, thanks folks. I was simply curious.

    I don't know anything about surround sound so those technical details are a mystery to me, but that is not a problem, I am happy for them to stay that way.

    There's no mystery. Dolby Digital/AAC can have 6 full frequency channels plus a 7th carrying low frequency (lfe - low frequency extension) that is designed to be sent to a seperately amplified subwoofer speaker.

    A basic system has outputs for speakers that are mounted front left and front right of the TV and one mounted centrally at the front (FL, Centre (ties the dialogue location to the TV centre), FR, and two rear speakers Rear left and Rear Right. The subwoofer can be almost anywhere.

    This allows the audio to be steered eg a Jumbo Jet flying in from behind you, screaming over your head and landing behind the TV.

    The centre speaker can make dialogue much easier to hear.

    Example of a simple 5.1 system

    Thanks Graham. Doesn't sound like the sort of thing that would fit into our already congested little room, so I think I will give it a miss!
