Today most Broadcast Video Encoders come standard with MPEG-2 Transport Stream based UPD/RTP IP output. IP based output offers several advantages over the more traditionally used DVB-ASI output. Some of these advantages include: cheaper cabling costs, no need to utilize expensive ASI switches, signal can be carried over much longer distances and ease of integrating with existing IP based systems. For broadcasters, IP based workflows offer much greater range of functionality at a reduced cost.
However what happens if you need to interface your equipment with “The Internet”? Well get ready for a mess of dropped packets, complicated port forwarding and unreliable service. In the age of high data speed, cheap bandwidth, and IPTV, utilizing the Internet is becoming necessary both for convenience and as a cost reduction method. Imagine this scenario, you need to send live video from New York to Miami, what are your options? You can either utilize very expensive and very limited satellite uplinks, lease a dedicated private WAN link or you can send this video over the Internet. This latter approach is the cheapest but will present some challenges to your existing video equipment.
You have several options, you can replace your existing equipment with new “Internet capable” equipment, deal with service interruptions and other complexities of having equipment that was meant for LAN work on a WAN, or use the ADARQ IP Gateway device.
