Abstract
Systems are provided for converting high definition pictures or data to lower definition images using wavelet transforms. In the preferred embodiments, the wavelet transforms are be used in either the transmission/coding or reception/decoding phase for enabling a more efficient conversion of the signal and providing a more robust and accurate output. The wavelet transforms may be applied to conventional systems to enhance performance or entire transmission and reception systems may be designed where the wavelet transforms are applied to the data for coding, decoding and decimation operations.
