Talk:Megabit per second
I contend this bit: "2 Mbit/s — VHS quality" - Sky in the UK broadcast digital TV at 2Mbps and the quality is much better than VHS, although noticably not as good as DVD (there are sometimes visible artifacts). Is this an appropriate comparison given digital and analogue formats will degrade differently? --Dan Huby 14:01, 13 January 2006 (UTC)
IEEE defines "Megabit per second" as "Mb/s". "Mbps" and "Mbit/s" do not denote "Megabit per second", see http://www.ieee.org/portal/cms_docs_iportals/iportals/publications/authors/transjnl/auinfo07.pdf
The same is valid for "kb/s", "Gb/s" etc. A capital "B" denotes "Byte". Why does Wikipedia still use the wrong unit of "Mbit/s" etc.?
B is the unit for Bell, not byte. --Xerces8 08:43, 10 September 2007 (UTC)
[edit] Elementary school math ?
The article says :
A megabit per second (abbreviated as Mbps, Mbit/s, or mbps) is a unit of data transfer rates equal to 1,000,000 bits per second (this equals about 976 kilobits per second).
Ant the linked kilobit per second link says :
A kilobit per second (kbit/s or kb/s or kbps) is a unit of data transfer rate equal to 1,000 bits per second
So 1 Mbps (mbps ? milli bits per second ???) is 1 000 000 bits which is 976 kilo bits which is 976 000 bit ???
This article need a serious cleanup. Including the bitrate/quality table. It is nonsense. Especially when no codec is specified. A modern codec like MPEG 4 AVC acts completely different than some old MPEG 1 ...
