MediaStar IP Multi-Mux Gateway for Multi-Channel Transport Stream Reception & Re-transmission (796)
When live TV channels are being delivered by a service supplier as an IP stream, these streams are typically delivered as unicast or multi-cast multi-channel MPEG transport streams.
The streams will be routed directly to the Multi-Mux ‘blade’, which will then analyse them to determine the incoming stream details. The TV channel names will be shown, and the administrator can then select which TV channels they wish to distribute via a simple browser-based GUI.
The selected TV streams can be AES encrypted so that the video and audio content is protected as it is distributed using single channel multicast streams across the LAN. Encryption is increasingly important as content providers insist on full content protection right up to the viewing device.
MediaStar Settops or PC/MAC software players pull the multicast streams from the LAN when users select the channel. They decrypt the stream and then show the live TV content at its original quality.
The Multi-Mux unit will automatically inform the MediaStar Media Manager software (model 478) when TV channels are made available so it can make new media icons. These icons can then be dropped onto playlists or channel selection lists that are allocated to individual displays or PCs.
The IP Multi-Mux ‘blade’ can be plugged into a standard MediaStar 770 rack or it can be used in a 769 single blade chassis. It has a single network interface which can receive and transmit a total of 600 Mbps and can simultaneously encrypt up to 15 TV channels.
The 796 ‘blade’ would typically be connected to a network switch which has VLAN segregation and security to isolate the internal corporate LAN from the external network source.
