I want to know the answer to the following question:
What is the minimum bit rate for compressed video and audio transmission?
All the background I'm provided with is that "It was only in the 1980s that digital telephony transmission networks became possible, such as with ISDN networks, assuring a minimum bit rate (usually 128 kilobits/s) for compressed video and audio transmission.". Is that enough to answer the question?
Answer: yes
