Video Stream Authentication

Overview of the video authentication flow

An operator can set parameters when initialising the event centre to enable or disable video in the UI. The message displayed to users can be configured in advance.

frontRowSeat.eventCentre({
  ..
  options: {
    videoPlaybackEnabled: true/false
  }
)

it would also be possible to update this value at runtime

eventCentreInstance.emit(MessageTopics.OPTIONS_UPDATE, {
    videoPlaybackEnabled: true
});

When a user presses play the event-centre will emit a message requesting the operator to authenticate the video playback.

.on(VideoPlaybackAuthRequest, {
  messageType: 'VideoPlaybackAuthRequest'
})

The operator should respond with the auth token using the existing guidelines described in IMG ALC Streaming documentation. It is important that the operatorId, and timestamp match those used to create the token.

.emit(VideoPlaybackAuthResponse, {
  messageType: 'VideoPlaybackAuthResponse',
  operatorId: '<OPERATOR-ALC-ID>'.
  auth: '<OPERATOR-ALC-TOKEN>',
  timestamp: 1576339325918
})

Stream Quality

The Event Centre plays a custom bitrate low latency stream which is suited for betting, streaming a 728kbps stream (600kbps Video and 128kbps Audio) at a resolution of 640x360.
