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.

Abstract: A multi-layer process for producing structural cementitious panels, includes, (a.) providing a moving web; (b.) one of depositing a first layer of loose fibers upon the web and (c.) depositing a layer of settable slurry upon the web; (d.) depositing a second layer of loose fibers upon the slurry; (e.) embedding said second layer of fibers into the slurry; and (f.) repeating steps (c.) through (e.) until the desired number of layers of settable fiber-enhanced slurry in the panel is obtained. Also provided are a structural panel produced by the present process, an apparatus suitable for producing structural cementitious panels according to the present process, and a structural cementitious panel having multiple layers, each layer created by depositing a layer of settable slurry upon a moving web, depositing fibers upon the slurry and embedding the fibers into the slurry such that each layer is integrally formed with the adjacent layers.
