bitstream is a term that applies to "packet writing"
"bit" is an abbreviation: binary digit.
Stream to denote as a packet
So to simply explain, when you see the terms 8bit, 32bit
or more commonly 24bit in DVD encoding, or the bit code
for your broadband connection.
Bitstreams are used extensively in telecommunications and computing.
example, the SDH communications technology transports synchronous
bitstreams,
and the TCP communications protocol transports a bytestream without
synchronous timing.
Note the diff spelling of bytestream, this denotes a special "packet" of
8bit, (8 binary digits
streamed as a "packet") so 3 bytestream is actually 24 bitstream as 3xpacket
stream -
but the timing is only synchronous within each packet.
If to be sychronus total, it will be a 24bitstream.
Now put the kettle on and have a cuppa tea.
