How to access DVBLink Configuration web page

General

DVBLink IPTV Server can either broadcast TV channels into the network, using UDP multicast or serve them via unicast (HTTP). The TV channels (all of them or individually selected) can be received at the client side using m3u playlist. This playlist can be downloaded from IPTV Server configuration page as described below. DVBLink IPTV Server also provides functionality to integrate TV channel streaming into Stalker ([1]) framework and into LG:ProCentric hotel network.

Transcoded streaming

Transcoded stream uses h264/AAC codecs for video/audio streams, encapsulated into mpeg-2 transport stream container. The transcoding bitrate can be set under "Server state" configuration.

Simultaneously active channels

Upon IPTV server start-up it opens all "Active" channels at the same time. It means that number of active channels should be selected according to the number of configured Sources and channel allocation on transponders. If all "Active" channels cannot be opened on IPTV Server start-up due to tuner number limitations, some of the channels will broadcast "All tuners are busy" message.
