One aim of the coding of PAL color signal is on compressing signals to 34 Mb/s which is compatible to the third PCM-hierarchy for transmission. If the intraframe DPCM component coding is used, the luminance signal must be compressed to 3-3.5 bit/pel. We suggest an adaptive full digital synthetic high coding scheme that could achieve this desirable rate. The difficulties on compressing signals to 3 bit/ pel is analysed, and the high compression performance of the separate channel synthetic high coding...

One aim of the coding of PAL color signal is on compressing signals to 34 Mb/s which is compatible to the third PCM-hierarchy for transmission. If the intraframe DPCM component coding is used, the luminance signal must be compressed to 3-3.5 bit/pel. We suggest an adaptive full digital synthetic high coding scheme that could achieve this desirable rate. The difficulties on compressing signals to 3 bit/ pel is analysed, and the high compression performance of the separate channel synthetic high coding is described. We suggest also some methods of adaptive coding and that for selecting the effective edges according to the statistics of edge in an image. For coding a high quality picture, our suggested group relevance address coding is efficient for accomodating more edges when the number of coding bits of a line is restricted to a given number We adopt FIR LP filter for the low channel, and design a synthetic high response filter which matches well with the LP filter. The results of a rate of 3.2 bit/pel and a weighted signal to quantizing noise ratio of 52.52 dB have been obtained by computer simulation.

PAL制采色电视信号编码以压缩到34Mb/s可容纳到脉码通信三次群中为一个目标。如果采用帧内DPCM分量编码方案,必须把亮度信号压缩到3~3.5bit/pel。我们提出了一个自适应全数字化综合高频编码方案可以达到这个目的。本文分析压缩到3bit/pel的困难,说明了分信道综合高频编码的压缩性能。其次根据图象边沿信号统计性质提出边沿信号的选择和自适应编码方法。对于高质量要求的图象采用一种“组关连度”编码方法来编地址码,在一行内可以容纳较多的边沿。在数字化方面采用FIR低通滤波器,并且设计了和低通滤波器相配的综合高滤波器。计算机模拟结果,在压缩到3.2bit/pel码率时,在质量上达到加权信噪比为52.52dB。

In this paper, three improvements to the digital synthetic imaging technique using multiple-hologram in cross-borehole electromagnetic methods[1-3] are proposed. The effectiveness of these improvements is confirmed by the numerical results of data processing for water-tank experiments and a field measurement. Moreover, some problems of the modified imaging technique which will be encountered in field data processing are preliminarily discussed, and a few tentativee ideas to solve these problems are presented....
