Features in Release Version 1.6.xx
Numerous changes have occurred in release 1.6.xx. Most of these relate to IP
and 3G IP connections. As a result, these sections have been extracted from all
codec reference manuals and have been amalgamated into a manual titled the
“IP & 3GIP Streaming Reference Manual”.
This manual contains all the latest connection information relating to IP and
3GIP in general. It also contains information about SIP connectivity and updated
quick start guides for studio and field unit codecs, as well as for wireless 3G
networks.
Following is a summary of the new and updated features that are contained in
the “IP & 3GIP Streaming Reference Manual”.
Updates to how to connect a codec for IP in a studio using a static IP
address;
Updates to how to connect a codec for IP in the field using DHCP
addresses;
Updates to how to connect a codec over 3GIP using new codec menus;
3G Modules available for GSM, GSM Voice, UMTS, EVDO and HSDPA
connections;
Codec interoperability using SIP;
Addition of the high quality, low delay
Music Plus
algorithm;
Support for IP dial/answer without using session data;
Permanent display of signal strength using 3G modules;
Information about how using v.1.6.xx software guarantees the ability to
use auto jitter buffer over IP/3GIP networks;
•
Also how if dialing to a lower software version than v.1.6.xx
jitter buffer defaults to the default fixed setting of 500ms.
Jitter buffer software changes;
•
New Auto Jitter Buffer use;
•
5 new settings for auto jitter buffer;
•
4 stages to jitter buffer when dialing and connecting;
•
Auto jitter buffer and how it works adaptively with FEC by
measuring FEC on a connection and adjusting the jitter buffer
appropriately to suit;
Full explanation of the "Connection Details" screen and the elements
within it, including:
•
How to use the new "Loss; Empty; Late; FECd" indications in
the "Connection Details" LCD screen to determine the
reliability and optimum IP jitter buffer and FEC settings;
How to order the right 3G data plan;
3G Antennae: how and what to select for the module purchased, i.e. EV-
DO versus UMTS/HSDPA
