8 Web Frontend 8. The web frontend on the CW-4412 is based on Java. This has the advantage of a quick and user friendly interface, but comes with a price to pay: you need to authorize the IP address of the CW-4412 in the exception site list, otherwise the recommended security settings 11 9 12 10 13 22 TELE-audiovision International — The World‘s Leading Digital TV Industry Publication — 11-12/2014 — www.TELE-audiovision.com
will obviously block the execution. Unfortunately, the fact that the web frontend relies on Java means that common Android or iOS devices cannot be used to configure the CW-4412. 9. START – WELCOME: A welcome screen is always nice. CableWorld uses this space to give a description of the device. This may seem unnecessary, but in a crowed head-end with lots of different devices you will quickly benefit from getting such a welcome screen, since you will immediately know, which device you just connected to. 10. START – QUICK SETUP:Here you can set up all relevant parameters in three tabs, which correspond to the CW-4112’s block diagram: it is composed of a LAN interface and two separate encoders. The only possible confusion should be avoided at this point: the LAN Settings refer to the IPTV output settings, not the IP of the web-frontend. 11. The quick setup screen for encoder 1. Here you can specify the input source and input format, as well as the output format. Notice that the CW-4412 can down-convert a resolution, but obviously it cannot up-convert a low resolution to a higher one: just use a high enough bandwidth for best image quality and you make viewers happy. 12. The setup screen of encoder 2 is naturally exactly the same as the previous, as both encoders have equal characteristics. Notice that the web-frontend will indicate if an input signal is preset, if the encoder is doing its job and if IP streaming is activated. 13. START – SUMMARY: These pages give you a full insight on the CW- 4412’s configuration and status. Organized in several tabs, the first one gives all information relative to the network configuration. 14. Next is the tab of the first encoder. Check marks tell immediately if everything is OK. 15. This tab shows information regarding the network output of encoder 1. Notice the first line in the picture: in this case, the encoder was not configured to output anything over the network. Also, you can see that the configured mode was Multicast, rather than Unicast. 16. The information tab of the second encoder, everything was OK. 17. But I also had not activated the streaming output over the network, when this picture was taken. 14 18. ENCODER – INPUT SETUP: Two tabs allow the independent configuration of each encoder. Just tell what signal input should be used and if you require to down-convert a resolution, you can configure that too: imagine you want to read a Full HD resolution on the HDMI input, but only generate a MPEG-4 stream with a SD resolution: no problem for the CW-4412. 16 17 15 18 www.TELE-audiovision.com — 11-12/2014 — TELE-audiovision International — 全球发行量最大的数字电视杂志 23
