Method and apparatus for network bandwidth conservation

摘要: Methods and apparatus for conserving bandwidth within a network based on two or more different service levels. In an exemplary embodiment, programming that is simulcast program channels mapped to one physical channel during periods when the scheduled at only level (e.g., standard definition), thereby would otherwise be consumed by simultaneous broadcast channels. When becomes heterogeneous across SD HD simulcast), channel(s) supporting content are provided local area “on-demand” using, example, switched digital allocation. Accordingly, no occurs given until least user requests it, further bandwidth.
