There are no industry standard guidelines for this like there is for voice.  It is entirely dependant on the equipment used.  Many vendors offer different rates for different levels of quality.  "Acceptable" and "unacceptable" are completely subjective and are determined by the user, rather than any true guidelines.  That being said, a very common transmission rate is 384Kb of pure data plus 10-15% transmission overhead.  Under 80-100ms delay is also typically encouraged.

If you're looking for "smooth video" 24 FPS, then the minimum speed that you will need to transmit and receive at is 256K.

There are two protocols that the world uses for video conferencing. These are H320 which is transmitted over dedicated ISDN (Integrated Services Digital Network) lines. Then there is H323 which transmits video conferencing over the Internet. Using dedicated ISDN by far is the best solution to date, much cleaner, no lost packets etc.

Hope that helps.

Charles
