Media Stream Receiver

Peak Level

(dBFS)

Meter displaying the Peak audio level.

Invert

Inverts the audio signal.

Mute

Mutes the audio signal.

Gain

(dB)

Controls the gain.

Status

This field displays the status of the Receiver in both text and color. The following is a list of possible status colors, and some example conditions.

OK - Green - Receiving stream, and audio is good.

Compromised - Orange - Receiving stream, but dropouts are detected.

Fault - Red –An internal fault occurred - see log for details.

Initializing - Blue - Receiver is connecting to stream or waiting for stream to begin.

Not Present - Gray - No stream specified.

Enable

Starts and stops the streaming.

URL

Enter the location of the stream source. This can be a source on the internet, or server, etc.

Stream Source examples:

• Unicast RTP streams:
  rtp://:<port number> (port number specified by the stream source)
  Example: rtp://:4848

• SHOUTcast
  http://streams1.kpfa.org:8000/kpfa_24
• StadiumVision
  udp://224.8.21.1:2000

• SDP
  http/live555://<IP address>/pcm.sdp

• SVSi:
  svsi://<stream number>
  Example: svsi://2

• WyreStorm streams:
  wyre://<mac_address_of_encoder>
  Example: wyre://xx:xx:xx:xx:xx:xx
  (lower-case letters only; colons required)

• Atlona streams:
  atlona://<multicast_address_from_encoder>:<port>

Buffer

Size of the internal network buffer. Longer buffer times improve network dropout resiliency at the expense of increased delay. You can use this control to adjust audio/video sync in mixed systems.

Interface

The network interface used to receive stream. Unicast sources can generally use "Auto" and the system will select an appropriate interface based on the available routing. All interfaces have Multicast reception enabled, so it may be necessary to specify on which interface multicast streams are present.

Interfaces can be LAN A, LAN B, AUX A, AUX B, and can be local or via the internet.

Preferred Language ¹

Select the preferred language from the drop-down list. If that language is available in the stream, the Current Language will show the language you selected in the Preferred Language field.

The default selection of "- -stream default- -" means whatever language is available is the one used.

Preferred ISO 639 Language Code ¹

This parameter is available only on the Control Pins of the component.

Three-character code reflecting the selection made in the Preferred Language field.

Current Language ¹

Drop-down list of the languages currently available. The default choice is "- - preferred language - -", which means, use what you selected in Preferred Language.

This control lets you choose what you're currently listening to and also reflects what's actually playing. For example, if Preferred Language is set to "- -stream default- -" and Current Language is set to "- -preferred language- -", once the track starts this control will change to reflect the language you're actually listening to. You can then use the control to temporarily switch to another track/language. This control is not "sticky" - if the track changes it reverts back to "- -preferred language- -". Track changes can occur if you change the source control, but can also happen if the remote source changes what is being transmitted.

Name

The name must follow standard naming conventions, restricted to the following:

ASCII characters a - z, A-Z (case insensitive)

Digits 0 - 9

Hyphen (cannot be at the beginning or end of the name)

Underscore (acceptable with a Q-SYS implementation)

No other characters, symbols, punctuation, or blank spaces.

Location

The Location is a means by which you can organize your virtual equipment to correspond to your physical equipment.

1. Click in the Location property field, the " Default Location" is highlighted.
2. Type the name of the new location. Once you have entered the new Location name, it is available on the pull-down for the Location property for all other equipment.

When you have given the location a name, the related equipment is now displayed under the new location. Any other equipment you identify as being in that location display under that location.

Mode

Select the type of output Channels.

The Media Stream Receiver automatically performs the appropriate up-mixing or down-mixing if the number of output channels differs from the channels available in the input stream.

Channel Count

Available when Mode is set to "Multi-Channel". If you have multiple Receivers in your design, the maximum total number of received channels is 16*6 (Cores 1000, 250i, 500i) or 32*6 (Cores 3000 and 4000).
