Getting Started

 

The Multisite Platform is a site-to-multisite audio/video streaming service which ensures the highest quality and reliability of video transmission and playback for hosted environments. This Getting Started guide is intended to help you understand the features of the platform and describe the best practices which can be applied to ensure a successful broadcast.

Platform Terms and Concepts

  • Host Sites & Remote Sites – A site (venue or location) where audio/video is captured and encoded is referred to as a Host Site. Any site where video is decoded and played back is referred to as a Remote Site. 
  • Encoder – The encoder is a device at the Host Site which accepts uncompressed video feed(s) and formats/compresses the signal to be sent to our cloud distribution network. The cloud distribution network then provides the media content to the remote sites. Some models of Multisite Encoders can also serve content directly to Decoders on the same network with LAN-delivery.
  • Decoder – The decoder is a device that receives the media content from the cloud distribution network (or directly from an encoder on the same network) and prepares it for playback with the Multisite Player application. Decoders are used at the Remote Sites for playback to an audience, and at the Host Site to monitor the stream and set Cues for the Remote Sites.
  • Control – The web portal used to start and stop encoders, as well as manage user accounts and privileges.
  • Administrator & Site User accounts – Every organization who has service with Living As One has at least one designated Administrator User account which is used to manage billing, user accounts, and user privileges. Beyond the Administrative User for an organization, each site (Host & Remote) will have a Site User account which is used to start/stop the encoder or login to operate the decoder.

General​ ​Platform​ ​Considerations

  • Living As One highly recommends operating a decoder at the encoding site for the following reasons:
    1.  To allow the host site to quality check the live stream and see exactly what the remote sites see.
    2. Set cues for their remote campuses. This is done most easily by those at the host site because they can see what is going on in person, whereas the remote campus only sees the video feed(s).
    3. Having a backup unit on hand in case there is a hardware issue with a remote campus decoder. Being able to replay events, and play live events from other churches and conferences.
  • If the encoder and decoder site(s) consistently have 2.5x the encoding bandwidth, a two minute minimum playback delay is recommend for decoders running in LAN mode, and a five minute minimum delay is recommended for decoders running in Cloud mode.
  • Start encoding during rehearsal and check audio and video early for any problems.
  • Each encoding event can be up to 12 hours. It’s easier for your remote volunteers to have a single event which contains multiple services, than for them to have to switch events. Use cues to identify [sermon] start/stop points within the service flow.
  • Add support@livingasone.com and alerts@livingasone.com to your email address book.

Encoder​ ​Installation​ ​Preparation

  • Physical​ ​mounting.​ All encoders are short-depth 2U rack-mountable. The encoder should operate in a well air conditioned room with adequate front and rear ventilation.
  • Encoder​ ​Power.​ ​Encoders accept standard 110-240V AC power, and come with 6’ power cable(s). It is recommended to power the encoder through an uninterruptible power supply and a voltage regulator.
  • Encoder​ ​Network(s).​ ​By default encoders are configured to accept a DHCP internet connection via Ethernet. Fixed IP addresses should be assigned through MAC-based IP Reservation on the router instead of setting a static address on the encoder. If the network requires that a static IP be set on the encoder itself, contact Living As One support so one can be set for you.
  • Video​ ​Input(s).​ ​All encoders can accept video over HDMI or SDI. By default the encoder is set to to SDI input; contact Living As One if HDMI is needed. If you have an encoder with more than one capture card but are only encoding one video channel, provide video to the capture card labeled with the lowest number.
  • Audio​ ​Input​. Audio should be embedded on the video input (HDMI or SDI). By default the encoder is looking for audio on the lowest numbered input card (if multiple cards are present). Certified audio embedders may be found on our Certified Peripherals web page. Audio may be transmitted with the following profiles: 2-ch, 5.1-ch, and 7.1-ch. Audio channels map 1:1 for input:output; channel 4 is low frequency only (20-120Hz). Important​ ​note​ ​about​ ​ATEM​ ​Switchers​: If you are using a BlackMagic Design ATEM 4K Switcher to embed audio for your encoder, please ensure you are running switcher firmware version 7.2 or higher due to an audio problem on earlier versions

Decoder​ ​Installation​ ​Preparation

  • Physical​ ​mounting.​ Decoders are short-depth 2U rack-mountable. The decoder should operate in a well air conditioned room with adequate front and rear ventilation.
  • Computer​ ​Monitor,​ ​Keyboard,​ ​&​ ​Mouse.​ ​A 16x9 DVI-D or HDMI monitor will be needed to control the decoder; analog video signals such as VGA are not supported. A wired keyboard and wired mouse will also be needed. If the monitor, keyboard, and mouse need to be extended for remote control from another area of a building, certified IP KVM extenders may be found on our Certified Peripherals web page.
  • Decoder​ ​Power.​ ​Decoders accept standard 110-240V AC power, and come with 6’ power cable(s). It is recommended to power the decoder through an uninterruptible power supply and a voltage regulator.
  • Decoder​ ​Network(s).​ ​By default the decoder is configured to accept a DHCP internet connection via Ethernet. Fixed IP addresses should be assigned through MAC-based IP Reservation on the router instead of setting a static address on the decoder. If the network requires that a static IP be set on the decoder itself, a static address can be configured on the login screen for the decoder.
  • Video​ ​Outputs(s).​ ​All decoders have two pairs of HDMI and SDI outputs for production video. Video is output over HDMI and SDI simultaneously, one video channel per pair. The video output format (resolution, scan type, and frame rate) must be initially configured via the UI before video will output. Decoders do not accept reference-in. If synchronized video is needed and a frame synchronizer is not available on the switcher or router, a Decimator MD-HX can be used to time the decoder’s output video signal (one Decimator per production video channel).
  • Audio​ ​Disembedding​ ​- Audio should be de-embedded from the decoder’s SDI video output. Audio is output over each SDI channel where video output is enabled. Certified audio de-embedders may be found on our Certified Peripherals web page. Audio output is mapped 1:1, matching encoder input with decoder output. Channel 4 is low frequency only (20-120Hz).
