Abstract
A bidirectional connection between a multimedia stream distribution system and a user is used to communicate operational data to and from the user. The bidirectional connection is separate from a multimedia connection that transfers a multimedia stream from the multimedia stream distribution system to the user. Providing a bidirectional connection separate from the multimedia connection is advantageous, among other reasons, because the operational data can be collected effectively at the multimedia stream distribution system independent of any limitations in the multimedia connection. To organize users and reduce processing load, the multimedia stream distribution system assigns users to user groups based on shared characteristics. Groups may be used to propagate information to the users as well as analyze information collected from the users in an efficient manner.
