Abstract
A method and apparatus for switching a source of an audiovisual program configured for distribution among a plurality of user terminals is described. In one example, a first real-time digital bitstream and a second real-time digital bitstream are received. The source is mapped to the first real-time digital bitstream. A request is received from a remote controller. The request is operative to switch the source of the audiovisual program. The source of the audiovisual program is switched to the second real-time digital bitstream in response to the request. Time stamp data in the second real-time digital bitstream is adjusted to provide a continuous time base for the audiovisual program.
