I listen a lot to BBC R4 by the net. There is however a 20 sec. delay compared with the same progamme on the radio. Do the wires slow it down that much?

It's not only the wires - it's the compression routines. The same thing happens
with DAB radio, but not by as much.

Thin wire problem

Get girt big cable and I'm sure it'll go much more quickly.

Re: Thin wire problem

It also depends where you live - obviously if the cable has to go uphill all the way from BBC house then it will take longer /forums/images/icons/crazy.gif

Certainly when provided by wire, not sure about the time lag with a dish though.

buffering

TCP/IP over the Internet does not guarantee timed delivery of data packets, so in order to get undisrupted reception the general solution is to keep a buffer in memory of twenty or so seconds of data, which is why you hear it twenty seconds later than the radio.

Thanks, I was just curious but I never cease to be amazed by the wealth of knowledge on this forum - some of it meaningful.

Me neither. I never knew that about electrickery going slower uphill.

[benjenbav]

stands to reason that it would go slower unless it's pressurised of course

So that's what an electric pump is for!

Nowt to do with delay I'm afraid its because you buffer 20 odd seconds (digital tv included) so that you don't lose the picture when the net goes dodgy.

Yeah, same with dish too.
