Abstract. Subband decomposition of HDTV signals is important both for representation purposes (to create compatible subchannels) and for coding (several proposed compression schemes include some subband division). We first review perfect reconstruction filter banks in multiple dimensions in the context of arbitrary sampling patterns. Then we concentrate on the special case of quincunx subsampling and derive filter banks to go from progressive to interlaced scanning (with a highpass which contains deinterlacing information) as well as from interlaced to progressive. We apply this decomposition to a sequence and indicate bitrates.
