摘要
Disclosed herein is a novel method and system for providing digitized television receivers with a multipicture display capability by zero masking high frequency transform coefficients. The system comprises means for decoding a signal for each of equal-sized subpictures by setting at zero those transform coefficients which lie outside a subblock of transform coefficients including a d.c. transform coefficient formed from a block of transform coefficients. Interpolation of pixel data is performed by applying appropriate weight factors on neighboring pixels based on the spatial relationship between a head of a reduced motion vector and its neighboring pixels.
