Just for the record, no one is to copy or record the streaming video.

Evan reported to the list tht the site would need either a T1 or DSL - DSL
cannot upload real
time video - it is the slowest of the broadbands
A t1 which is over a thousand times faster than Cable - both do not split
with each connection
like DSL - would be the minimum at the show site
You can have a T3 also which is three T1
For people into math, I have expanded the explanation to include
definitions of speeds
T1 - Digital signal 1 (DS1, also known as T1, sometimes "DS-1") is a
T-carrier signaling scheme. A T1 line is a dedicated circuit that
connects to the internet with a speed of 1.544 Mbps
T1 - now means any data circuit that runs at the original 1.544
Mbit/s line rate. Originally the T1 format carried 24 pulse-code
modulated, time-division multiplexed speech signals each encoded in
64 kbit/s streams, leaving 8 kbit/s of framing information which
facilitates the synchronization and demultiplexing at the receiver.
T2 and T3 circuit channels carry multiple T1 channels multiplexed,
resulting in transmission rates of 6.312 and 44.736 Mbit/s,
respectively
DSL - The download speed of consumer DSL services typically ranges
from 384 kilobits per second (kbps) to 20 megabits per second (Mbps),
depending on DSL technology, line conditions and service-level
implementation. Typically, upload speed is lower than download speed.
DSL or xDSL is a family of technologies that provides digital data
transmission over the wires of a local telephone network
Cable Internet systems can typically operate where the distance
between the modem and the termination system is up to 100 miles (160
km). If the HFC network is large, the cable modem termination system
can be grouped into hubs for efficient management.
Downstream, the direction toward the user, bit rates can be as much
400 megabits per second for business connections, and 100Mbit/s for
residential service in some counties. Upstream traffic, originating
at the user, ranges from 384Kbit/s to more than 20Mbit/s. One
downstream channel can handle hundreds of cable modems. As the system
grows, the cable modem termination system can be upgraded with more
downstream and upstream ports.
Definition of Bandwidth
The amount of data that can be sent from one computer to another
through a particular connection in a certain amount of time. The more
bandwidth available, the faster you are able to access information.
Most poeple in the United States for example, connect to the Internet
from home using modems that can transmit 56Kbps (Kilobits per
second).
What is a Bit?
A bit is a single digit number in base-2, in other words, either a
zero or a 1. This is the smallest unit of computerized data.
Bandwidth is usually measured in bits-per-second.
How much is a Kilobit?
A common unit of data measurement equal to 1024 bits. A kilobit is
usually referred to in the context of bit rate per unit of time, such
as kilobits per second or Kbps.
What is a Byte?
A set of Bits that represent a single character. Usually there are 8
Bits in a Byte, sometimes more, depending on how the measurement is
being made.
How much is a Kilobyte?
A kilobyte is a 1024 bytes of information. A Web page usually
contains between 15-25 KB of data, including images. Kilobyte is
usually abbreviated as K or KB.
How much is a Megabit?
A megabit is roughly one million (precisely 1,048,576) bits. Mbps is
a unit of measurement in digital transmission rate, it indicates the
number of megabits transmitted in one second. Most ethernet network
cards are rated up to 10, 100 or 1000 Mbps, although the actual
speeds are usually about half that (If you're lucky). Wireless
network cards are rated around 11 and 54 Mbps, but because of
overhead, those speeds too rarely reach what is promised.
How much is a Megabyte?
1 Megabyte = 1,048,576 Bytes.
How much is a Gigabit?
A Gigabit is Approximately 1 billion bits or 1 bit x 1,024³ or
1,073,741,824 bits.
How much is a Gigabyte?
1 Gigabyte = 1,073,741,824 Bytes.
