ABSTRACT:
A method for the regulation of the throughput of assistance data is provided. The assistance date assists in the reconstruction of subsampled moving electronic images. The method is particularly useful for HDTV transmission by a HMAC channel. For each elementary block of the image, an optimal processing operation is selected from first and second parallel processing operations. The second processing operation includes an image filter, and the first processing operation includes a motion compensation process. The first processing operation generates a larger data throughput rate of assistance data than the second processing operation. If the throughput rate of assistance data approaches or exceeds the maximum throughput rate permitted for a transmission unit, the second processing operation which produces a smaller data throughput rate is automatically selected.
