B-Codec streaming section

Streaming connection

Standard RJ45 Ethernet connection TCP/IP

Standards supported

MP3 Layer 1 (32, 44.1 and 48 kHz)
MP3 Layer 2 (16, 22.05 and 24 kHz)
G.711 (µLaw / aLaw 8 and 24 kHz sampling rate)
16bit PCM uncompressed (8 and 24 kHz)


IP standard based protocols; TCP/IP, UDP, HTTP, ICMP, SNMP
Supports BootP, DHCP and Auto IP
It supports RTP for low latency

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
