摘要

A method for remediating broadcast digital television signals is disclosed. A television signal is buffered by a multimedia client, and analyzed for errors. If errors are detected, replacement data for the corrupted data are requested from a service provider using a network back-channel. The replacement data are obtained from the broadcasting entity and sent back to the multimedia client. The replacement data are used to generate and display a faultless version of the digital television signal.
