Master Control Workflow

This chapter defines and describes tasks that are typically performed by the automation system after control of the playlist has been handed over by the scheduling system in the traffic department.

This section contains information on the following topics:

Activate the Playlist

A playlist that has been activated for the currently selected channel enables Media Sequencer to start transfers of full screen video clips from your media asset management system (e.g. Viz One) to Viz Engine for playout.

When activated the Media Sequencer is made aware of the playlist’s schedule. Without it, the Media Sequencer will not be able to initialize the elements and run the playlist properly. Hence, once activated you can Initialize the Playlist.

A playlist may be automatically activated based on Rules and/or Day Switch Options (the latter is common for broadcast day playlists) or manually by clicking the Activate button (when the playlist is open).

To Manually Activate the Playlist

  1. Select your channel.

  2. Click the Playlists button.
    All existing playlists for the selected channel are displayed.

  3. Open your playlist.

  4. From the Playlist Toolbar, click the Run Playlist button.

  5. Initialize the Playlist.

  6. Run the Playlist.

Initialize the Playlist

An initialized playlist, initialized for the currently selected channel, has all its pages (i.e. the graphics which includes embedded video clips and imagery) loaded on the program Viz Engine for playout.

When activated and initialized the Media Sequencer is aware of the playlist’s schedule and is able to Run the Playlist.

A playlist may be initialized based on Rules (common for continuous playlists), Day Switch Options (common for broadcast day playlists) or manually by clicking the Initialize button (when the playlist is open and active).

To Manually Initialize the Playlist

  1. Select your channel.

  2. Click the Playlists button.
    All existing playlists for the selected channel are displayed.

  3. Open your playlist.

  4. Activate the Playlist.

  5. From the Playlist Toolbar, click the Initialize Playlist button.

  6. Run the Playlist.

Run the Playlist

A playlist in run mode has been activated and initialized for the currently selected channel. This means that all full screen video clips and all pages (i.e. the graphics which includes embedded video clips and imagery) are available and loaded on the program Viz Engine for playout.

When in run mode the Media Sequencer has a playlist that is activated and initialized and the system can take elements on air.

A playlist is in almost all cases automatically run by the Media Sequencer. If there are multiple broadcast day playlists, they run according to Day Switch Options. A playlist can be manually run by an operator, but this is not recommended nor common.

Note: Only one playlist per channel can be in Run mode at a time.

To Manually Run a Playlist

  1. Select your channel.

  2. Click the Playlists button.
    All existing playlists for the selected channel are displayed.

  3. Open your playlist.

  4. Activate the Playlist.

  5. Initialize the Playlist.

    When in Run mode, the film roll icon seen at the top of the playlist will turn green. When stopped, the icon will be grayed out.

Whenever manual intervention is required, you may control the playout using the control buttons available on the Playlist Toolbar.

Triggers

Triggers can be set on Primary Events an Secondary Events (i.e. pages and video clips). Note that triggers are configured in the Basic Settings. Triggers are only accepted when a Playlist is in Run mode.

Primary events

Primary events are triggered by automation systems that send triggers to start playing out groups (primary event/element). All secondary events that exist under each group are automatically played out by Viz Multichannel. Playout of the secondary events is relative to the time of the trigger of the primary event and based on the secondary events’ defined offset.

Secondary events

Secondary events can be triggered by automation systems. This includes all types of secondary events such as pages with video clips and video clips with graphics overlay.

In the case of secondary events, Viz Multichannel will simply act as a slave system listening for triggers to take events on air.

Monitoring

In most cases Viz Multichannel requires little or no monitoring as it in most cases is the automation system that controls the playout. Also, in the Control Room you typically monitor playout live on TV displays set up for that purpose. In addition you can also see the same on the dedicated Viz Engine machine (if one is setup).

When monitoring is required you can see the status of the Media Sequencer in the left pane. If the channel configuration is OK, lights will be green. If there is any problem, lights will be red. Mouse over the red light for an indication of the problem. This will tell you if the Media Sequencer and your configured playout devices are working properly.

To Disable the System Status LED Panel

  1. In Windows Explorer, browse to Viz Multichannel’s installation folder and open the VizRundown.ini file in the text editor of your choice.

  2. Under GUI OPTIONS, ensure that the value for IsIndicatorsPanelEnabled is set to 0.

  3. Save and close the file.

  4. Restart Viz Multichannel.

Live Schedule Updates

If playlists are expected to by highly changeable, it is recommended that updates be done in the scheduling system and updates to Viz Multichannel be done automatically and frequently, using the automatic import.

Once a playlist is in Run mode, Viz Multichannel can be 100% synchronized with the schedule from the automation system.

Failover Procedure

In the case of failover, you need to be prepared beforehand to accommodate such a situation. The following procedure will help you be prepared and to subsequently take additional actions as required.

The prerequisite to backing up is to have an extra machine for the Viz Engine and Media Sequencer, as well as for the Viz Multichannel client.

To Back up your Viz Multichannel Client

  1. Prepare the client machine as described in the Playout section.

  2. From the main client, copy the channels.ini files to the backup client.

  3. In the event of a client failover, launch Viz Multichannel from this backup client.

To Back up your Channels

  1. Prepare a Viz Engine machine that can accommodate any existing channels, meaning with Viz Engine and Media Sequencer installed.

  2. Add the remote host as a new remote host for all channels to this backup machine, in accordance with the General Settings.

Channel Failover Procedure

  1. Modify the channels.ini file on the Viz Multichannel client so that failed channel points to the backup machine, as described in the Playout section.

  2. Restart the Viz Multichannel client.

  3. Select the failed channel, initialize today’s playlist, and run it.

  4. Set the video router to point to the new machine.
