Table 1: UDP IP Broadband Uplink Bandwidth Table
Please note:
T
ieline
recommends that your broadband service in your studio is not
shared with other users as this will decrease the available bandwidth for your
broadcast signals and may cause instability.
7.3.9.
MPEG 2 Layer 2 Recommended Bitrates
The following tables indicates the connection bitrates that are recommended
for
MP2
(MPEG 2 Layer 2) algorithm connections, which are available in
T
ieline
codecs. The possible bitrates for mono, dual mono, stereo and joint
stereo (J-stereo) connections are provided for ISDN, X.21 and IP
connections.
The recommended bit rates are the ones that will provide the best quality
audio at different sample rates. If you configure your codec via the
connection wizard then only the recommended bit rates are displayed for
each connection sample rate and each MP2 algorithm.
7.3.9.1.
Dual Mono MP2
If connecting using a dual mono profile with
MP2
algorithms it is only
possible to use these profiles using either two ISDN B channels or two
X.21 module connections. It will require either two 64kbps B channels or
two 64kbps (minimum) X.21 connections.
Dual mono MP2 is not possible over IP or 3G/IP. There is only one plug-
in module slot in an
i
-Mix
G
3
so dual mono MP2 audio cannot be sent
using an X.21 interface with this codec.
