Select Encoder

Choose Your Encoder(s):

Step 1 – Choose encoders for your broadcast site(s). One encoder is needed to begin with multisite, but you may want to choose multiple encoders if you may stream from multiple venues or to use for campus video review.

Things to keep in mind:

  • Encoders are headless – no monitor, keyboard or mouse is required. Plug in your source, internet, and power, and you’re set!
  • Planning on multisite in the future or paranoid about quality? We recommend a PRISM encoder, as it is capable of the highest bitrate.
  • RAY Encoders support SDI, while PRISM support SDI and HDMI. (What’s the difference? How can I use HDMI with a RAY?)
  • Both PRISM and RAY encoders receive audio embedded on the SDI or HDMI input. (What is embedded audio?)
  • It is possible to stream to both multisite and web from one encoder, but we recommend separate encoders if possible.
  • Setup is a breeze, but don’t worry – we’ll send checklists to get you prepared after the purchase, and our Support team is ready to help make sure that you’re up and running optimally.
  • Resi encoders are enabled by your choice of Resi platform service plan.

FAQs

What is an encoder? Why do I need one?

An encoder is a device, whether hardware or software, that will take a video input from a source (such as a camera or switcher) and send it to the cloud for distribution and viewing. Most utilize unreliable protocols which send video data to the cloud like a laser beam, resulting in buffering, glitching, and dropped frames due to even minimal packet loss.

 Resi is the first system that can provide 100% video delivery without interruptions. To do this, we take advantage of the Resilient Streaming Protocol, which unlike RTMP or other protocols such as SRT or Zixi, takes advantage of a local cache in order to check and re-send data until video content is verified as perfect. This is what makes Resi unique and is only available through Resi’s encoders.

Should I have an encoder at each campus?

Only one encoder is required to get started streaming from one site to another. Purchasing additional encoders is great to have flexibility for broadcasting from other campuses as needed, streaming to independent web streams from those campuses, or monitoring video feeds from each campus through video review.

What is SDI? Can I use an HDMI source instead (for example, with a RAY?)

An SDI video input is similar to HDMI but can travel over much longer distances and is a much more robust video standard thanks to its ability to carry more data and locking connectors. 

 Using an HDMI source? No worries! An HDMI to SDI converter like the ones below can be used to convert your HDMI source to SDI, and start at around $40. Make sure to also get an SDI cable to connect your converter to the encoder.

Blackmagic Micro Converter ($39)

Blackmagic Mini Converter ($145)

AJA HDMI to SDI ($345)

What other hardware do I need?

Encoders are headless – no monitor, keyboard or mouse is required. Plug in your source, internet, and power, and you’re set! Keep in mind that encoders utilize embedded audio through either SDI or HDMI inputs. Often, your switcher or other video device may already embed audio on your video signal if it has an audio input. Otherwise, you may need an audio embedder. 

What is embedded audio?

Resi’s hardware encoders support up to 16 channels of audio embedded on the SDI or HDMI input. If you’re using a switcher with audio inputs or have audio running into your video source, you’re already set. If not, an audio embedder can be used to combine your audio with video before it comes into the encoder with SDI, or an HDMI to SDI converter like this one can convert your source to SDI and embed stereo audio with one device.

Can one encoder be used for both multisite and web?

About 60% of our customers who are streaming to both physical sites and web will use separate encoders for two reasons:

  • To be able to send unique content to both destinations
  • For optimal quality – multisite streams are typically streamed at a much higher bitrate than web, so if a single encoder is used for both purposes, the video is encoded at a lower bitrate to send reliably to both destinations.

For these reasons, we recommend unique encoders if possible, but it is possible to stream to both with a single device.

What is the difference between a single-channel and dual-channel encoder?

A single-channel encoder will transmit a single video signal (up to 4K for PRISM or 1080p for RAY) to physical receiving sites and to web destinations. 

A dual-channel encoder (PRISM only) can transmit a single video signal (up to 4K) or two video signals (up to 1080p each) to physical sites. These video channels will be played back with perfect synchronization at receiving sites, great for virtual speaker shots or clean feeds (see example). 

While it is possible to use a dual-channel encoder to send the unique signals to two destinations (e.g. one channel for multisite and one for web), we do not recommend it as the entire video data is sent to receiving sites causing unnecessary bandwidth usage, and the channels must be individually re-transcoded, resulting in slightly lower quality.

How much bandwidth do I need to stream?

Resi’s platform ensures that every frame of video data makes it to viewers before they see it, resulting in a perfect viewing experience without buffering even if the connection at the broadcast site is consistent. However, in order to ensure that there are no delays causing data to get to the cloud within the RSP backup cache, 2.5x your bitrate is recommended for upload bandwidth at the broadcast site. When your connection experiences packet loss, this allows the encoder to re-send data to the cloud faster than real-time so your viewers don’t notice a thing!

 

For typical resolutions, this means:

720p: 4-8Mbps

1080p: 10-12Mbps

Don’t have this? Most likely, you can still stream. Contact us to talk about your setup.
