Configure a Broadcast site (Office Web Apps)

Office Web Apps

Published: May 16, 2012

The information that is provided in this article about how to configure a Broadcast Slide Show site is intended for IT pros who maintain Microsoft Office Web Apps installed on Microsoft SharePoint 2010 Products on a stand-alone server or on a server farm. SharePoint 2010 Products in this article refers to Microsoft SharePoint Server 2010 and Microsoft SharePoint Foundation 2010 unless otherwise noted.

Configure a PowerPoint Broadcast site

Broadcast Slide Show requires that Office Web Apps be installed on SharePoint 2010 Products on a stand-alone server or server farm, the PowerPoint service application be created, and a broadcast site collection be created. If the PowerPoint service application is created during post-setup configuration of a stand-alone installation or by running the Farm Configuration Wizard, a default broadcast site is also created. In most cases, the default site’s URL is “http://<server name>/sites/broadcast”. Setup also installs a broadcast site template. Multiple site collections that use the broadcast site template can be created.

If the PowerPoint service application has not been created during post-setup configuration of a stand-alone installation or by running the Farm Configuration Wizard, you can create the PowerPoint service application manually. To learn about how to create Office Web Apps service applications manually, see Activate the Office Web Apps services and feature by using Windows PowerShell in Deploy Office Web Apps (Installed on SharePoint 2010 Products). If the PowerPoint service application is created manually, to use PowerPoint Broadcast Slide Show, a PowerPoint broadcast site must also be created manually.

For Broadcast Slide Show sites that were created manually, administrators must give users appropriate permissions through SharePoint 2010 Products to broadcast a slide show and to attend broadcast slide shows. For Broadcast Slide Show sites that were created by default, authenticated users are added to both the Broadcast Presenters and Broadcast Attendees groups; however, we recommend that administrators verify that appropriate permissions are given for their organization.

Important Important:

Users should not be granted Full Control or Full Read policy permissions to a Web Application that contains a broadcast site collection. This circumvents the permissions on the broadcast site and might allow users to access broadcast documents.

Procedures in this task:

Some procedures in this task require using Windows PowerShell or SharePoint 2010 Management Shell to run cmdlets. To run SharePoint 2010 cmdlets in Windows PowerShell, you must add the Microsoft.SharePoint.PowerShell snapin by using the Add-PSSnapin cmdlet, or you can run the SharePoint 2010 cmdlets by using SharePoint 2010 Management Shell. By default, the Microsoft.SharePoint.PowerShell snapin is already registered, and the snapin is added to the SharePoint 2010 Management Shell. To run SharePoint 2010 cmdlets, you must be a member of the SharePoint_Shell_Access role on the configuration database and a member of the WSS_ADMIN_WPG local group on the computer where SharePoint 2010 Products is installed. To run scripts in Windows PowerShell or SharePoint 2010 Management Shell, you must set the execution policy by using the set-executionpolicy cmdlet, using the unrestricted parameter. For more information about the Add-PSSnapin cmdlet, see Add-PSSnapin. For more information about how to use Windows PowerShell with SharePoint 2010 Products, see SharePoint 2010 Products administration by using Windows PowerShell.
