Video signal encoding method with a substantially constant amount of transform data per transmission unit block |
摘要 |
A method of encoding a video signal into highly efficiently encoded data comprises the steps of: digitizing and blocking the video signal; performing a discrete cosine or Fourier transform on the blocked data; controlling the amount of data in each block to be substantially constant according to an amount of encoded data awaiting transmission; calculating a threshold amplitude; and selecting data larger in amplitude than the threshold amplitude as encoded data for transmission.
