Planning Broadcast Slide Show Using Office 2010 Web Applications

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.
Before planning your Broadcast Slide Show solution, it is recommended you first read the

In this article:
  • Plan service types
  • Plan broadcast site location
  • Plan permissions
  • Use Group Policy to manage Broadcast Slide Show
  • Summary

Plan service types
Two types of broadcast services are available:
  1. 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.
  2. 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.

PowerPoint Broadcast Service
  • User Type: Internal and  External
  • Connection: Internet Connection
  • Intended For: Smaller businesses with limited IT resources, Organization wanting a low impact solution for internal and external presentations, Organizations with fewer content security or compliance requirements

Internal Service
  • User Type: Users with permissions to SharePoint broadcast site
  • Connection Type: Office Web Apps installed on SharePoint 2010 Products
  • Intended For: Larger businesses with dedicated IT resources, Organization whose communication and collaboration needs are primarily internal, Organizations with strict content security or compliance requirements

Plan broadcast site location

If you perform a standalone 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:///sites/broadcast”. In most cases, this URL is “http:///sites/broadcast”, where 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.

Plan permissions
An internal deployment of Broadcast Slide Show enables broadcasting using the functionality 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:
  1. Broadcast Presenter Gives users permission to broadcast.
  2. Broadcast Attendees Gives users permission to attend broadcasts. 
  3. Broadcast Administrators Gives users permission to change membership on the site.
Most organizations will be able to provide broadcast services to all their users through a single default installation of Broadcast Slide Show. For additional flexibility, an organization may choose 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 may 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
