A set-top box generates a multimedia signal that includes streaming video for a plurality of currently available multimedia channels. A user configures a plurality of favorite channels. Streaming video from the favorite channels is provided in a plurality of viewports on a display. A user presses a favorites button on a remote control to prompt an application server to signal a content server to provide a compound video signal including streaming video from each favorite channel. The set-top box produces a resultant video signal including the streaming video from each favorite channel in a corresponding viewport. The viewports correspond to a mosaic template that may be hosted by the application server and accessed by the content server.
