Introduction
Audio Talkback
Makito X User’s Guide, v2.2, Issue 02
41
There is no audio mixer on the Makito X, so the talkback feature is “First-In/First Served”,
meaning that only one user can use the return audio channel at a time. The InStream player
application provides “push-to-talk” functionality, which requires that the user push a button
to transmit audio. The user must keep pushing the button to use the talkback channel. This
prevents the user from accidentally locking and not releasing the channel.
The audio is only sent to the source video encoder; it is not distributed to other viewers of
the stream.
The Talkback network service may be stopped or started from the Web interface (Services
page, see
“Enabling and Disabling Network Services” on page 190) or using the service
command.
CLI commands are used to enable and disable reception of talkback audio, set the talkback
volume, clear talkback statistics, and display talkback information. For details, see
“talk-
back” on page 361 (CLI). Talkback audio is not configurable through SNMP in the current
release.
NOTE
Audio talkback is uncompressed audio (using approximately 350 kbps of network
bandwidth).
