Abstract: A method and apparatus automatically manipulates a digitally compressed video bitstream such that the result is compatible with different bandwidth and error resilience requirements at a receiving point in a heterogeneous communication network. The method and device provide for analysis of bitstream header information to determine its relevant coding syntax parameters. Feedback from the receiving point on the network is then used to identify error robustness requirements for an intermediate bitstream. The bitstream is then manipulated by an error robustness regulator to achieve error protection in the network.
