  • Apparatus and method for the compression and transmission of multiformat data
    Patent number: 5182642
    Abstract: Video data is compressed, at a first site, by a transform scaling data compressor (12), and carrier signals are modulated with audio and digital data by a delta modulation data modulator (14) and a delta-sigma modulation data modulator (16) respectively. Their output signals are combined by a multichannel data compressor (18) and transmitted to a second site, where the procedures are essentially reversed to effectively regenerate the data as originally formatted.
