Regardless of the hype that surrounds frame rate claims, there is some very simple mathematical truths that must be understood. If you have a 56K modem your connection speed is 56,000 bits per second, if you're using a 28.8 modem your connection speed is 28,800 bits per second. Also, If you're using a cable modem your connection speed may be in the 256,000 bits per second range and of course a T-1 user may enjoy 1,544,000 bits per second with their connection. Packet size is the number of bits in each frame of video. Video size is the size of the actual window that the customer is receiving.
Quality is the level of fine detail that the performer, or up-loader, chooses to send to the viewer.
The two parts, video size and quality, can work opposite of each other in determining the packet size. For example, a video feed with a size of 240 X 180 and a high level of detail may have the same packet size of a larger 320 x 240 sized video set to a lower detail level. For reference, a 320 x 240 sized video can have an average range of anywhere from 500 bits per packet to 15,000 pits per packet depending on how much detail the up-loader chooses to send. A final note on Frame Rate. Many factors can adversely affect your received frame rate.
