However, RTMP Push methods are a completely different story. You open the door, invite them in, and they walk through. Think of this like inviting someone into your home. This is because the HyperCaster is requesting a stream from the internet, and thus a stateful firewall would permit that request since it originated from behind the firewall. In the RTMP Pull method, firewalls tend to not be an issue. The HyperCaster can also pull using other more modern protocols include HTTP Live Streaming (HLS). This may be useful if you’ve got a football game that two stations need to simulcast, or perhaps a large community event that needs to be distributed to dozens of places at once. You could configure your RTMP encoder to stream to a CDN such as the TelVue CloudCast player, and then have multiple HyperCasters “tune in” and retrieve that stream. Take, for example, you may need to share a live stream with multiple HyperCasters at once, possibly in geographically different areas. In this model the HyperCaster would be reaching out to a RTMP server or CDN on the internet and retrieve a stream to playback. RTMP Pull, while it’s still the same protocol, uses a slightly different process. This is likely the most common use case for stations using the feature whereby you will be pushing a stream directly to the HyperCaster for ingest and processing. Once the device is setup and the HyperCaster configured this method will allow you to go live from virtually anywhere that you have a reliable internet connection. An RTMP Push process means that if you have a device or application that can output RTMP like a TeleCast 2 streaming encoder, a Teradek Cube, Telestream Wirecast, a NewTek TriCaster, the LiveU Solo, or multiple other hardware or software solutions, you can deliver that feed directly to the HyperCaster via LAN, WAN, or Internet. The TelVue HyperCaster can take RTMP inbound connections both ways, though the “push” process would probably be the more common use case. RTMP has two primary methods of transport- Push, where a streaming encoder delivers the RTMP to a RTMP Server or CDN, and Pull where the client retrieves the stream and plays it back.

Given it is TCP based, and thus stateful, it has built-in resiliency when used as a transport across networks that might have some packet loss, such as the public internet.

While Flash streaming has declined over the years, the RTMP protocol remains the primary method for streaming encoders to deliver to CDNs (Content Distribution Networks). RTMP is a protocol developed by Adobe designed for real-time (live) video streaming across the internet. What follows is a primer on the RTMP protocol and how you might use it. The TelVue HyperCaster supports ingest of RTMP (Real Time Messaging Protocol) streams.
