![]() ![]() Both satellite and video fiber carry substantial “occasional use” charges. The chief advantage to acquiring video over IP is cost. These networks can be multicast–for one-to-many transport– as we did with the 2010 Vancouver Olympics, or they can be unicast for a one-to-one path. ![]() This is normally utilized over private IP networks. The last and perhaps most unusual of the three off-site methods is IP transport. It can be more of a hassle, in that case, than the extra stability is worth.ģ. That’s usually not the case and so fiber transport becomes very costly because you need to have your own local loop and a video codec installed. There’s simply less moving parts than with satellite, but fiber transport does require that the venue you’re in has connectivity to a video fiber network. Either way, while there are still things that can go wrong, they’re usually due to operator error and are easily fixed. So there are a few options but primarily, if you use fiber, you are either transporting uncompressed video which can be a whopping 1.5 gigabits-per-second with HD content or you can compress the video using standard MPEG codecs and transport over ASI at greatly reduced rates. By video fiber, I’m referring to certain fiber optic networks that are dedicated to video transport. For these reasons, some customers choose video fiber as their primary acquisition path– sometimes with satellite as a backup if the event is very high-profile. There are also weather issues to contend with and truck positioning is always a concern.Ģ. Digital equipment is relatively troublefree, but RF gear is notoriously finicky. When you’re sending radio waves 22-thousand miles out into space and back, though, there can be a few hiccups. Depending on where the event is taking place, I can have a satellite uplink truck on-site in a matter of hours. It’s sometimes the easiest method and almost always the fastest. Foremost, and certainly the one I utilize most often, would be satellite. There are a number of options to explore:ġ. Of course, that means you’ll need to get your video feed to that off-site location. If on-site broadband connectivity isn’t an option, or you’re simply not comfortable with the potential pitfalls of on-site encoding, then you’ll want to encode off-site, either with your own acquisition setup or through a managed service provider like iStreamPlanet. Of course, a Teradek Cube is about one-tenth the cost of Cisco’s leading AnyRes box. ![]() There’s no support for encryption or DRM or captioning or multiple audio tracks or a lot of the features that are offered by enterprise-class encoders like Cisco’s AnyRes line or the Elemental Live family. These devices output a single stream– either RTMP or MPEG-2TS– and that’s about it. ![]() The only downside is the limited feature set. These devices are small, rugged and really easy to operate. There are a bunch of new entries on the low-cost end of this field, but my favorites are the Teradek Cube and the Teradek Slice. Another option for on-site encoding would be a dedicated appliance. ![]()
