Protocols
|
|
|
|
Studio link
|
Using
a streaming host (Solidyne provides one temporal to test the MX 2400),
the Journalist only needs to connect the codec to Internet to start the
digital transmission
|
|
|
Latency
(time delay)
|
MB2400
has a latency of only 50 mS The full loop including Internet and receiver software in a direct conection is between 0,5 sec to 1,5 sec Using an iceCast host streaming server this value usually raise to 1 - 5 sec |
|
|
Voice
IP identification
|
When
MX2400 is connected to a LAN network for codec programming, a voice response
in English can be heard at headphones in order to get the IP address of
LAN
