摘要：
Channel changes between services with differing bandwidth in a switched digital video system. A services map published by the headend and distributed to all of the edge devices, allows a bandwidth requirement to be correlated with each request from a device in the home. The bandwidth requirement is passed upstream along with the request for service and is subject to a system resource management validation.
