Internet Protocol television (IPTV) is a system through which internet television services are delivered using Internet Protocol Suite over a packet-switched network infrastructure. IPTV offers the best possible way to distribute TV and video channels within a building, around a business, or across several company sites.
How IPTV Works
- Digital TV channels direct from a terrestrial aerial and satellite dish are IP “wrapped” for transport across the IT data network as IPTV streams.
- Other sources such as DVD and SKY satellite receivers are MPEG encoded and they too are output as IPTV streams on the IT network.
- The IPTV channel streams are distributed ONLY to the destinations that request a channel, by using multicast protocols. Each channel stream is placed on the network once and is replicated as necessary by the network switches. This minimizes the data overhead on the network.
- IPTV Receivers or Digital Signage players convert the IPTV streams back to video and audio for display screens.
- IPTV Player software shows IPTV channels on computer desktops and can offer PVR functionality.
- A Video on Demand (VoD) server can be added for recording, storage, and on-demand playback of IPTV channels and programmes.
