Abstract

A system and method for recovering lost/damaged attribute data in a bitstream of encoded data comprising attribute data and encoded sample data is disclosed. The decoded neighboring data is retrieved and lost/damaged attribute data is estimated using the encoded sample data, the decoded neighboring data, and available attribute data. In one embodiment, this is used in the transmission of video signals over a potentially lossy communications channel.
