Adaptive coding and decoding of frames and fields of video

摘要: Improved compression of digital signals relating to high resolution video images is accomplished by an adaptive and selective coding frames fields the images. Digital input are analyzed a type signal produced in response this analysis. This may be used adaptively control operation one or more types circuitry which compress so that less bits, slower bit rates, transmit without undue loss quality. For example, improve motion compensated estimation techniques, quantization transform coefficients, scanning data, variable word length encoding data. The improved useful for conferencing applications definition television, among other things.
