Abstract
Methods for managing delivery of video sequences of an interactive program guide (IPG) over a communications network to a plurality of terminals are provided. In one embodiment, the method pre-allocates a broadcast bandwidth in the communications network for common video sequences to be transmitted by a broadcast technique. The common video sequences are transmitted in the broadcast bandwidth to the plurality of terminals by way of the broadcast technique. A request for a specific video sequence is received from a specific terminal via the communications network. A demandcast bandwidth is allocated in the communications network for the specific video sequence. The specific video sequence is transmitted in the demandcast bandwidth to the specific terminal via the communications network.
