Failing to deliver your live stream to the cloud, studio, or any online destination is the scariest potential single point of failure for any live producer. IP bonding<\/a> is the simplest and least expensive way to ensure your stream goes through. <\/strong>This article describes what IP-bonded streaming is, how it works, and how major players in this space support it.<\/p>\n\n\n\n

Background<\/h2>\n\n\n\n

Whenever you stream using a single transmission method, whether Ethernet, WiFi, cellular or even satellite, if the connection goes down, your production goes down. IP bonding ensures against this by combining multiple signals – including all of those mentioned above – into a single production transmission.<\/strong><\/p>\n\n\n\n

You see this in Figure 1, where a camera person is transmitting the live feed from a camera using the combined signals from multiple 4G\/5G modems with satellite and WiFi. Depending upon the field unit<\/a>, you can transmit multiple camera inputs simultaneously or just the single camera shown.<\/p>\n\n\n\n

Under the hood, the compressed video file is divided into multiple packets distributed using all available transport mechanisms. Once delivered to the cloud, the packets are reassembled back into the original video file, which you can distribute to multiple private or public destinations, including social media. When sent to a LiveU decoder, the packets are reassembled and then typically input into a linear TV production via HD-SDI outputs on the decoder.<\/p>\n\n\n\n

The Need for IP Bonding<\/h2>\n\n\n\n

IP bonding was invented to address the reality that for those attempting to deliver their live streams via early cellular technologies like 3G and 4G, one connection was never sufficient for throughput or reliability.<\/strong> Bonded streaming technologies use multiple cellular connections, plus available WiFi and Ethernet, to improve both characteristics and enable many contributors to affordably deliver high-quality video from locations that otherwise would have been inaccessible \u2013practically or economically. IP bonding replaced costly traditional transmission methods, providing far greater flexibility.<\/strong><\/p>\n\n\n\n

Though 5G is a significant step up in throughput, it doesn’t eliminate the need for multiple-connection bonding. Certainly, under ideal circumstances, 5G can deliver a single or even multiple 4K streams. But the reality is that 5G coverage and throughput will vary by geographic location and perhaps even the day or time. A tower free from traffic one day could be totally congested the next. Of course, if you’re gathering news, producing sports, or shooting any event involving a crowd, you probably won’t be the only producer seeking 5G transport<\/a>.<\/p>\n\n\n\n

Combining multiple 4G and 5G signals via IP bonding provides both resiliency and redundancy. This bond allows your transmission to leverage multiple connections with one or more providers to ensure signal throughput \u2013 even when conditions are far from ideal. Combining 4G and 5G signals with Ethernet, WiFi, or satellite, when available, provides even more bandwidth and headroom.<\/strong><\/p>\n<\/div><\/div>\n\n\n\n

How you use IP bonding will depend upon the specifics of your production; here\u2019s a partial list of the most common uses of IP bonding:<\/span><\/strong><\/h3>\n\n\n\n
