Audio streams
The BC840-MC provides bidirectional audio. The BC840-MC can send three audio streams to
different destinations, multicast or unicast, to an A-80, or any C-/S-series codec with an audio
interface. It can also receive one audio stream from an A-80 or any C-/S-series codec that
features audio.
Highlighted fields
The source address and port number fields are highlighted in green when the enabled receiver
receives a stream from the specified source. The two fields are marked in red when no stream
is received with the receiver enabled and correctly configured.
Two-way audio
The figure above shows the setup for two-way audio on the side of the BC840-MC. The device
on the other side of the connection (with the IP address 172.22.250.131) would need similar
settings, that is - it must hold the IP address of the BC840-MC as the destination and source.
Transmitters and receivers must be enabled in order for streaming to start. Remember to
Save a configuration to make it effective.
SDP download
Use the SDP Download button to download a Session Description Protocol (SDP) file from the
encoder. SDP files contain streaming media initialisation parameters and properties. An SDP
file does not deliver media itself but through file association the media stream can be opened
in media players such as QuickTime and VLC. You can also use the SDP file to specify the URI
in your web browser.
