Abstract
A method, apparatus and computer program product for providing scalability for channel change requests in a Switched Digital Video system is presented. A request for a channel change is received. A determination is made regarding whether a channel requested by the request for a channel change is currently being provided to the settop box. When the channel requested by the request for a channel change is being provided to the settop box then the request for a channel change is buffered for transmission at a later time. When the channel requested by the request for a channel change is not being provided to the settop box then the request for a channel change is immediately sent to an SDV server in communication with the settop box.
