Abstract
A physical adapter receives a data stream comprising data usable to derive a rendition of a signal at a first level of quality and reconstruction data produced by processing a rendition of the signal at a second, higher level of quality and indicating how to reconstruct the rendition at the second level of quality using the rendition at the first level of quality. The physical adapter reconstructs the rendition at the second level of quality and outputs the reconstructed rendition and/or data derived from the reconstructed rendition. The physical adapter is connectable to signal processing equipment that outputs the data usable to derive the rendition at the first level of quality. The physical adapter increases the quality of the rendition of the signal relative to the first level of quality and enhances the functionality of the signal processing equipment.
