ADC-100 by Harris Broadcast

This section describes how to configure the Automated Content Management and Distribution system (ADC-100) by Harris Broadcast for Viz Multichannel. It describes the setup on the ADC side and contains information on the following topics:

General Information and Setup

An ADC-100 system can trigger Viz Multichannel (by sending commands to Media Sequencer) through VDCP or Universal Sercom Device (USD) using either TCP/IP or VDCP.

Note: Both version 11 and 12 of the LST format are supported.

The advantages of VDCP are that it is:

  • Standard

  • Proved to work for many customers

The advantages of USD are that it:

  • Can be used over TCP/IP thus saving serial ports and additional cabling.

This section contains information on the following topics:

Triggering

Triggering should be Primary/Secondary Events selected.

Primary Event Defaults should be Triggered (Ext) selected. The ADC-100 system reads playlist data via files in LST format (binary files).

Reconcile field value in the LST is read into the Event ID field in Viz Multichannel and must be set in order to receive playlist updates. An empty or corrupted Reconcile value will omit that event from the update procedure.

If primary events triggering is selected then Viz Multichannel can import the same LST file that is provided by the ADC-100 system because the data required for the triggering is available in it.

If secondary events triggering is selected and all Vizrt secondary events are received from the scheduling system (in the LST file) then Viz Multichannel can import the same LST file that is provided by the ADC-100 system because the data required for the triggering is available in it (as long as secondary events contain assigned ID fields).

If secondary events triggering is selected and there are Vizrt secondary events that are generated by Viz Multichannel (manually or by import rules) then Viz Multichannel must export a new LST with the data required for the triggering in it.

Updating LST by Export

When exporting, Viz Multichannel will ensure that all secondary events have a Media ID value assigned and assign this value to the LST ID field, if secondary events triggering is selected.

Exporting LST from scratch or merging into the original LST are both optional. Merging is preferable since merging only appends the new secondary events to the LST file and will assure that original data is not touched.

Updating LST by Import

Two mapping options are available: with or without secondary events.

Refer to the (folder path) folder in Viz Multichannel installation for sample mapping settings and playlists.

Channel name can be read from the filename. If the filename does not contain a channel identifier, either do not map channel value or set Traffic Channel Name to 1 in Viz Multichannel’s Basic Settings.

Updating Live

Recovery (RCV): The Harris ADC-100 can auto-generate a recovery file (*.RCV) on every playlist change. RCV files are in LST format. Viz Multichannel can monitor a folder and update its playlist according to the RCV file once it is generated.

Broadcast Exchange Format (BXF): Viz Multichannel supports processing BXF schedules.

LST files managed by Schedule Collector tool: Schedule Collector can monitor a folder for LST update files. Using its cache memory, updates will be attempted only for changed events.

Limitations

The LST format only allows for 32 character titles and misses other necessary fields such as local language titles.

Allow replay – Media Sequencer virtually removes played events from its exposable list, so Vizrt events will be marked as MISSED on ADC-100 side although played successfully.

Trigger Viz Multichannel Using VDCP

The standard configuration of Viz Multichannel is triggering by a serial connection using Video Disk Control Protocol (VDCP).

Any Device Server version permits controlling Viz Multichannel, provided that it has a Video Disk driver.

Connections

Use an RS422 board on the machine with Media Sequencer, for example: Blue Heat/PCI of Connect Tech Inc. The following custom cables are required to connect the Media Sequencer to the ADC-100 system.

Device Configuration

Configure the Software

  • Make sure the COM port used has the following suggested parameters under Windows Configuration on the Media Sequencer machine:

    images/download/attachments/72090809/automation-integrations_adc1.png
    • Bits per second: 38400

    • Data bits: 8

    • Parity: Odd

    • Stop bits: 1

    • Flow control: None

  • Enable the VDCP device on Viz Multichannel and ensure it is switched on and configured properly with the correct port.

Configure the Viz Driver

  1. Launch the ADC-100 Configuration Utility and locate the icon that represents your Device Server.

  2. Right-click the icon, and select Configured Devices.

    images/download/attachments/72090809/automation-integrations_adc2.png
  3. In the Available column on the left, locate the Standard Video Disk driver under the Video Disk category. Click and drag the driver to one of the channels on the Configured column that reads NO DEVICE.

  4. Double-click on the Disk device that was just created. From the resulting dialog select the* Serial Port* tab.

    images/download/attachments/72090809/automation-integrations_adc3.png
  5. Select the physical port the Media Sequencer is connected to. The Harris Device Server is now configured properly to communicate with the Media Sequencer.

  6. Configure the following parameters on the General tab:

    • Device Name will appear in the Device Status and configuration windows on the client applications. The default name may be used, but it is recommended to use unique names to ease later identification.

    • ID Match Name will be used in the Transmission List’s *ID Field *to let the system know that the event is intended for the Vizrt device.

    • Stop Disk Play can be selected as required.

    • Back to Back Play can be selected as required.

    • Update Event Duration from Disk must remain unchecked.

      images/download/attachments/72090809/automation-integrations_adc5.png
  7. The Vizrt Standard Video Disk must also be assigned to a Transmission List to be scheduled to air.

    Note: The Standard Video Disk driver cannot be used if you are using Extended IDs. In addition, the Media Sequencer does not contain the notion of duration, so the parameter Update Duration from Disk must be unchecked to avoid excessive error messages when ADC driver asks for the IDs list.

Operation

Viz Multichannel uses Secondary A/V or Secondary Backtimed events to execute the pre-loading and playout of media.

Notes

When an event is triggered (primary or secondary), the command take id is sent where id is the Media ID value in Viz Multichannel and ID field value in ADC-100.

  • Harris playlist (.LST) USD format:*

    • TITLE field: macro_name:trigger_id (Media ID). For example: VIZRT:MCP2

    • ID field: USD_NAME (device) name

    • Reconcile Key field: Template name

  • Harris macro format: trigger_command [1]{D0A}. For example: PAGE_START [1] {D0A}. {D0A} is the char symbol for Enter.

Operation

Viz uses A/V, Secondary A/V to execute the pre-loading and playout of media.

Automatic Playlist Updates Using RCV Files

Auto List Save allows automatic list savings based on the number of list changes that occur on an active on-air transmission list.

Number of changes value indicates how often the list is automatically saved to an RCV file.

The RCV file will be read by Multichannel, which will update its playlist accordingly.

Enable Auto List Save

  1. From the main menu select Properties > Auto List Save. The Auto List Save dialog box is displayed.
