Page 17: Wifi Access Point
9.2.6. “Wifi Access Point” Your AQORD features a WIFI access point, allowing direct access to the Web Interface to set the encoder without requiring network configuration. AQORD is provided with a USB WIFI Adapter. When it is plugged on a USB port on the back of the AQORD, the WIFI access point is available. To connect directly to the web interface, use a WIFI device (PC, tablet, smartphone...) and connect to the WIFI access point "AQORD_xxxxx" (SSID is the the “machine name”), default password is "digigram38" (or enter the web interface password if it has been changed). Then enter the following URL in your Web browser: " h ttp://wifi.digi " (any other “Http” addresses will be automatically redirected to " h ttp://wifi.digi " , not “Https”). Note: ● By default the WIFI turns off automatically 10 minutes after the encoder powers on. To reactivate WIFI access point, restart the encoder or simply unplug and plug again the USB WIFI adapter at the back of the AQORD. ● Number of connected devices is limited to eight. If no USB WIFI Adapter is plugged on the AQORD, you can see the following on WIFI web page: If your AQORD is not equipped with USB WIFI Adapter, you can get one anywhere. Compatible USB WIFI Adapters are TRENDnet TEW648UBM, NETGEAR WNA1000M, but also any dongle based on RTL8188CUS chipset. When a USB WIFI Adapter is plugged on the AQORD, you can see the following parameters on WIFI web page: ... -

Page 46: Typical Applications
The AQORD can address different markets like Broadcast and IPTV. This section presents some typical applications for these markets like: ● Full Duplex video transfert for conferencing, training, meeting for corporate or academic applications. ● Point to point contribution to t ransmit h igh video quality o ver long distances through IP network. ● Live Event Contribution to Studio for video processing. ● Contribution using Octoshape Infinite HD technology. ● IPTV video distribution on Local Area Network for SetTopBox or computer player. For more information on how to configure AQORD for point to point application, request to Digigram support the guideline document : “Point to Point Contribution Application Installation guide“ 16.1.

Page 47: Dual Streaming
16.3. Dual Streaming For the contribution range AQORD encoder/decoder : the new dual streaming feature help to secure video transport between two locations (ex: from event field to the studio). Dual streaming is for point to point contribution market (AQORD). This schematic shows IP Satellite + Internet link dual streaming redundancy. In that case the AQORD encoder (location 1) pushes the stream to the two different links then the AQORD decoder (location 2) will sort the received packets (received in double). If one of the links transmission is interrupted, the contribution will continue on the second one. 16.4. Duplex application : academic application example AQORD *LINK 2C product has full duplex capability. It has two completely independant channels. Each channel can be configured as an encoder or a decoder. This flexibility allows to stream two different contents between two locations in the same or opposite directions. ... -

16.6. Octoshape Point to multipoints contribution application example AQORD embeds Octoshape (Akamai) Broadcaster that allows to benefit to Octoshape specific protocol. See more details on Octoshape Technology h ere . The schematics below shows a point to multipoints contribution through Octoshape Servers. The AQORD pushes only one stream to Octoshape server and several AQORD can request the stream for decoding purpose. ... -
