A system and method for bandwidth management by controlling the bit rate of a signal stream in real time according to available link bandwidth. Applications include multiple-channel video data streams over a limited-bandwidth link such as a Digital Subscriber Line. A video signal is transrated at the head end to multiple streams having different bit rates, by a multirating device which sends the multiple streams over a network, along with metadata containing information about the data structure and parameters of the streams. At the network access edge, a demultirating device uses the metadata to select the stream with the highest video quality whose bit rate does not exceed the available bandwidth of the end-user's access link. This scheme provides multiple unicast signals to different end-users in place of a single multicast signal, supports multiple high-definition channels over a limited bandwidth link, and is compatible with standard encryption methods.
