Channel WORM Ac-227 now live.

Greetings from Music City, as we broadcast live…

…hmm.  This is problematic.  We’re pretty sure we’re live, as we type this.  God willing, we’ll still be live as we post it.  But it won’t be live to you.

Come to think of it…you never witness anything as it happens.  What you think you’re witnessing “live” is the past, back when those photons just began their journey, not ended it.  Back when the sounds were first made, not heard.

If we have to get technical about it–and you know do–you can’t even make love to another person “live”.  You react to the past, not the present.

Depressing?  Maybe this will cheer you up.  If you’re watching a football game on television, you can hear the calls and plays before most of the people at the stadium.  The sound of that crushing hit reaches the TV microphones, gets translated into electronics, broadcast, reconverted to sound by your TV and played through its speakers...before it reaches the furtherest bleachers

Kinda cool, huh?  From a thousand miles away you can hear something before people sitting right there.  Hopefully it makes up for the revelation that nothing in your life is ever live.

This is all important enough that we’re going to go ahead and claim this post as a Public Service Announcement.

    by the time the sound goes through DISH, it is a little delayed I think. I’m not sure if that is true of most digital …

    Ah, its been awhile since I took relativity, but I believe time propagates along the light cone, or rather, two events laying on the same light cone are simultaneous.

    When you get down to where the speed of light being a foot a nanosecond matters, it is not enough to say what time it is, but what time it is *where.*

    Yeah, I’ve been accused of being a pedant before. Have a good one!

      Sometimes it’s today here but already tomorrow in Australia. Why are we the ones who have to live in the past?

        The good news is that Asia and Europe get to make the mistakes first, what with living “ahead” of us. The bad news is they get to the beer first. . .

    AAAAAAAAAAAAAAArgh!

    The sound getting there first is only true for an analogue link. Any digital link will have multiple delays, introduced by each piece of equipment buffering complete frames internally both on input and output. Compressors delay a variable amount, as they store so as to get a big enough pool to generate a constant bitrate from the variable output from the DCT encoder. Add in delay to and from GEO at least thrice ( your local broadcast very likely was sent from an OB van to GEO, then from the central mixer to the transmit base station via another GEO hop to enable all the mux to be done to create the baseband signal, and from there to the DBS receiver) and you can get a delay of up to 2 minutes on the signal. Even local radio suffers from this, the digital multiplex is generally around 30 seconds behind the FM signal, as that is carried on a direct microwave link from the studio via line of sight.
