DIGITAL RECORDING AND REPRODUCING APPARATUS FOR TELEVISION SIGNALS |
摘要 |
Disclosed is a digital recording and reproducing apparatus for television signal, which is designed to record and reproduce by sampling a television signal at a frequency lower than the Nyquist frequency, by dividing the sampled signal into blocks each of which is composed of adjacent plural sampling points, by orthogonally transforming in each block, and by subjecting the orthogonally transformed signal to weighted quantizing. The apparatus has achieved the reduction of recording bit and decrease of error propagation rate simultaneously so as to be applicable to recording and reproduction even in a home use VTR. |
