  • HDTV system with receivers operable at different levels of resolution
    Patent number: 5049992
    Abstract: A 787.5 line progressively scanned wideband video signal is sub-band coded for providing a plurality of (9.times.9) blocks of spectral coefficients, each representing a respective spatial portion of the video signal. Each block of coefficients is transmitted in truncated form and received by either a first receiver or a second receiver. The first receiver processes the received coefficients for deriving a (9.times.9) block of video pixels corresponding to each block of coefficients and produces a high resolution 787.5 line progressively scanned video image in response thereto. The second receiver processes the received coefficients for deriving a (6.times.6) block of video pixels corresponding to each block of coefficients and produces a lower resolution 525 line progressively scanned video image in response thereto.
