Broadcast Publishing Versus On-Demand Publishing

Broadcast publishing is a process where the publishing of a video is scheduled, similar to a television program. A time is scheduled when the stored video file will be played back. This might be used in an environment in which training videos are played back during specific times during the day for employees to view.

On-demand publishing is a process where an individual requests the playback of a video file. This allows users the flexibility of deciding when they watch a video. As each session is independent with on-demand video, there is no benefit to doing a multicast session because the video will only be viewed by an individual. Therefore, the default delivery option for on-demand published videos is unicast, and the multicast option is not provided.

When choosing a broadcast published video, because multiple users are likely to access the broadcast at the same time, the organization can choose to multicast the video as long as the remote client systems and network infrastructure support multicast video routing. With multicast delivery, the Enable Unicast Rollover option provides a unicast delivery stream if the remote client does not support multicast broadcasts.
