Planning a Live Stream
There are several factors to think about when planning a live stream to ensure that the event is successful and runs smoothly.
Connectivity is perhaps the most important aspect to consider when planning a live stream broadcast.
We typically stream at up to 6Mbps during a broadcast, at variable bit-rate, meaning that certain elements, such as static graphics don’t require as much data as moving video.
There are different options to consider:
Venue internet connection
A site visit would usually be carried out as part of the planning process for the event. During this time, on-site connectivity would be tested.
We ideally require 10Mbps dedicated upload capability (allowing for overheads) during the stream. This connection should be hard-wired and not shared with anyone else (IE bandwidth shared with WIFI users).
There should also be no port-blocking or restrictions on the network for creating an outbound connection. We specifically require open ports for:
- TCP 80
- TCP 443
- TCP 1935
- TCP 9443
- UDP 53
- UDP 2088
Depending on the result of our on-site testing, we may recommend that we supply our own internet connectivity, solely for the live stream.
Where we recommend that we supply our own connectivity, this will be either bonded 4G LTE (depending on location and access to 4G network and network saturation) or dedicated, uncontended 1:1 access via KA-SAT satellite internet, via the NewsSpotter service – or a combination of both.
Utilising KA-SAT, we can stream from any location, even if there’s no venue internet connectivity or 4G mobile signal. Providing we can site our satellite dish outside and get a clear view of the sky, unobstructed by trees or tall buildings, we can go ‘live’.
Depending on the size and scale of the event, we can provide a single camera – either static or manned, through to a multi-camera vision-mixed production. Again, this requirement would be established early in the planning process. We can utilise a mix of manned, static or remotely-controlled camera heads to give the required coverage.
For events which just require a single static camera, our stream encoder can be mounted directly to the camera, making our setup footprint minimal.
If your event already has cameras, simply supply a vision-mixed output either by HD-SDI or HDMI and we'll do the rest.
There are various options to consider when planning the audio and sound mix for the event.
If there’s already provision for a mixing desk at the venue that’s operated by part of your team or subcontractor, we could take a sound feed directly from the desk to supply the audio from the live stream.
Our preferred method is to supply our own sound technician, mixing desk and microphones – specifically for capturing audio for the live stream.
Graphics / Presentations
As part of the live stream, if graphics or PowerPoint / Keynote slides are required to be mixed into the stream output, we can accommodate this with our vision mixer.
Depending on the setup, we can either take a feed directly from the presentation computer and use as a direct input in our switcher, or convert the slides into JPEG images which can be mixed as static graphics into the stream.
Similarly, if any video ‘VT’ content requires playing as part of the stream, we have media server capabilities to play back the video content.
We can stream to various streaming destinations, including Facebook, YouTube, Twitter (Periscope), Twitch and Vimeo Live.
We can also stream to a Content Delivery Network (such as Wowza) to provide a customisable embeddable player directly on your website.
Working alongside our various event delivery partners, we can also provide a robust, moderated audience chat facility which can be embed on your website next to the video player, allowing viewers to ask questions during the broadcast.
When live streaming an event, all content should be free of copyright or copyright-cleared for use during the broadcast.
This includes using images taken from online, video content from YouTube or similar sources and copyright music.
Many content platforms, including YouTube and Facebook Live operate copyright algorithms which run in the background of the site, searching published content for any possible copyright infringements. Streams can be stopped during the broadcast if copyright content is detected and can lead to blacklisting of the account in question. See Google's support article on copyright.
The simplest solution is not to use any copyright content (audio, video, images) in your event.
