What is ?
A to Z
Pick a letter to get a list of definitions on that letter.
A
AAC
Advanced Audio Coding
AMR
The Adaptive Multi-Rate audio codec is designed to work at low bit rates from 4.75 kbit/s to 12.2 kbit/s.
Aspect ratio
This is the ratio in height & width of your image.
B
Bandwidth
It's the rate at which data can be sent over the connection.
Bit
It is a single piece of information.
Byte
A Byte is made up of eight bits.
C
Codec
It stands for compression-decompression, there are many Codecs out on the market.
D
Data Rate
This is how much data is played through in a given point of time.
Data Size
Data size is the total size of your file.
E
Enable streaming
This option will add two hinted tracks to your .3gp file so you can stream from your server.
F
FTP
File Transfer Protocol is a way of transferring files over a network/internet to another computer.
FPS
Frames Per Seconds - How many frames are played in one second.
G
3G
GPRS
General Packet Radio Service also known as GPRS or 2.5G
H
H.263
H.263+ or Apple VC H.263
This are one and the same, they are more of a advanced version of H.263 codec.
Hinted Movie
This is a movie where it has two additional tracks, one hinted audio track and the other hinted video track. After a movie is hinted it can then be placed on your streaming server.
I
IP address
This is a numeric address to connect to a computer, or any other network device, be it on your network or on the internet.
J
K
Key frame
The key frame contains all of the information for an image. Subsequent frames contain only the information that has changed.
L
LAN
Local area network. This is your internal network.
M
mp-3
This is the compressed audio format by the Moving Picture Experts Group.
mpeg-4
MPEG-4 is an ISO standard developed by Moving Picture Experts Group. It is designed to run on all multimedia digital platforms, from high-level broadcasting though to small mobile devices.
Multicast
Multicast allows many clients to receive the same server steam. (Compare with Unicast.)
N
O
Optimize for server
This option will make your file bigger but it will help the streaming server get your file out faster.
P
Pass-through
If you have already your source footage compressed, then by selecting Pass-through it will not re-compress it.
Q
R
Re-synch markers
This helps with loss recovery when streaming.
RTP
Real Time Protocol is the protocol for sending real-time streamed content.
RTSP
Real Time Streaming Protocol, difference with RTP is that it sends interactive streamed content.
S
SDP
Session Description Protocol file is a text file that contains information on live streams that your computer can play back.
T
TCP
Transmission Control Protocol, unlike UDP, TCP will resend any lost data but it will be slower due to checking data loss.
TTL
TTL or Time To Live, is the number of timse a packet can be passed over a router till it dies. The maxim setting can be 255 & the minimum is 1. So for example if the value was set to 45 that packet in your stream would die when it hit the
45th router on its way back to the streaming server.
U
UDP
User Datagram Protocal, compared to TCP does not support packet loss, so it will not retransmit lost data.
Unicast
A separate transmission is required from the server to each client.
V
W
WebDAV
This is another way of transferring files over a network/internet to another computer. It's also the same technology that Apple use for iDisk.
X
WAP
Wireless Application Protocol
