Planning Broadcast Slide Show (Office Web Apps)


Applies to: PowerPoint Web App Preview

Topic Last Modified: 2010-04-15

Broadcast Slide Show is a new capability in Microsoft Office 2010 that enables presenters to broadcast a slide show from Microsoft PowerPoint 2010 to remote viewers who watch in a Web browser. Broadcast Slide Show provides companies with a low-infrastructure presentation broadcast capability that works through the Web.

Information provided in this article is intended for IT Pros planning to use Broadcast Slide Show as part of Microsoft Office Web Apps installed on Microsoft SharePoint 2010 Products on-premises in their organizations. SharePoint 2010 Products in this article refers to Microsoft SharePoint Server 2010 and Microsoft SharePoint Foundation 2010 unless otherwise noted. New and updated content will be published on a regular basis.

Before planning your Broadcast Slide Show solution, we recommend you first read Understanding Broadcast Slide Show (Office Web Apps).

Plan service types

Two kinds of broadcast services are available:

  • PowerPoint Broadcast Service   By default, PowerPoint 2010 provides all presenters with a link to the public PowerPoint Broadcast Service hosted by Microsoft. This service requires presenters to sign in with a Windows Live ID. Presenters who use this service receive a public Internet link that they can share with anyone on the Internet they invite.

  • Internal Services   You can host your own broadcast service with Office Web Apps installed on SharePoint 2010 Products. You create one or more broadcast services by creating sites collections that use the PowerPoint Broadcast site template and set permissions for who can use the service through group membership on the site. Up to ten services can be specified.

Plan broadcast site location

If you perform a stand-alone installation of Office Web Apps, or run the Farm Configuration Wizard with the PowerPoint service application service selected, the PowerPoint service application is automatically created. A default broadcast site collection is also created under the default Web application at “http://<default web application>/sites/broadcast”. In most cases, this URL is “http://<server name>/sites/broadcast”, where <server name> is the name of the server.

NT Authority/Authenticated Users is automatically added to the Broadcast Presenters and Broadcast Attendees groups of this default site, granting all users access to create and view broadcasts.

You can also create one or more broadcast sites manually by creating a new site collection in SharePoint using the PowerPoint Broadcast Site template.

For more information about how to create a Broadcast Slide Show site, see Configure a Broadcast site (Office Web Apps).

Plan permissions

An internal deployment of Broadcast Slide Show enables broadcasting using the functionality that is provided by PowerPoint Web App and a SharePoint site. Administrators can control which users can present and attend by giving users the appropriate permissions to this site. Three levels of permission are available:

  • Broadcast Presenter   Gives users permission to broadcast.

  • Broadcast Attendees   Gives users permission to attend broadcasts.

  • Broadcast Administrators   Gives users permission to change membership on the site.

Most organizations will be able to provide broadcast services to all users through a single default installation of Broadcast Slide Show. For additional flexibility, an organization may decide to configure multiple broadcast sites with different permissions. For example, a company wants to provide broadcast services to their product marketing department to share presentations internally. They create a new broadcast site and grant permissions only to members of the marketing department.

Use Group Policy to manage Broadcast Slide Show

Organizations can use Group Policy to configure and manage Broadcast Slide Show. Broadcast Slide Show supports the following Group Policy controls:

  • List of Broadcast Services

    • Up to 10 services can be specified

    • Ability to specify name, URL, and description for each

  • Disable access to the public PowerPoint Broadcast Service

  • Prevent users from adding to the list of broadcast services

  • Turn off access to Broadcast Slide Show through the PowerPoint desktop application

  • Turn off programmatic access to the Broadcast Slide Show object model
