Operating Manual for FLASHMAN II
3.5.4.4.9 AJC
The feature AJC (= Automatic Jitter Compensation) provides an automatic
adaptation of the IP transmission to network capabilities when using the
interfaces Ethernet, 3G or WLAN.The AJC optimizes the following parameters at:
a) Encoder side:
The information provided by the peer via RTCP is used for evaluating the network
capabilities. If applicable the packet size is increased first, to improve the
transmission (a bigger packet size results in less IP overhead). If increasing
packet size does not lead to satisfactory results then the encoder bit rate will be
reduced automatically.
·
Mode: AJC can be selected to
- auto: AJC is enabled
- off: AJC is disabled
- default: AJC is reset to factory default
(In this version: default = auto)
·
Time (s): Set evaluation time in seconds (by default 30 seconds)
b) Decoder side
If necessary the audio delay is increased to adapt the transmission to a current
network conditions. Increasing the audio delay is achieved by increasing the
receive buffer for incoming IP packets.
·
Mode: AJC can be selected to
- default: AJC is reset to factory default
- auto: AJC is enabled
- off: AJC is disabled
·
Time (s): Set evaluation time in seconds (by default 30 seconds)
Further information on AJC technology will be available in the MAYAH Application
Note #33 via MAYAH web-site.
3.5.4.4.10 BGAN
The Broadband Global Area Network (BGAN), is a global Satellite IP Network
using portable terminals.
FLASHMAN II is connected to a terminal via Ethernet interface, just like to any
other Ethernet switch.
In this menu the BGAN mode can be activated or deactivated.
MAYAH Audio Codecs support the following terminals:
·
Thrane & Thrane: Explorer 500, 700
·
Addvalue Communications: Wideye Sabre 1, Wideye Sabre Ranger
·
Hughes Network Systems: 9201, 9250, 9350
Most BGAN Terminals are also DHCP Servers, so it is recommended to enable
