Method for compression and transmission of video information

摘要: A facsimile transmitter capable of transmitting graphic as well text material, by telephone or wireless. digital code derived from scanning the document to be transmitted is truncated eight bits per pixel six pixel. The three most significant each are run length encoded in bit bytes, so that wherever same appear adjacent pixels, these once, followed a five indicating number times (up 32 times) repeated succeeding pixels. resulting bytes similarly encoded, transmission double encoded. An fine resolution byte for that, conjunction with pixel, (i) entire one-fourth (ii) four intermediate between six-bit and (iii) only one-half disposed transmitted. At receiving end pixels having expanded averaging values preceding which were Then immediately following Each scanned line contains an error detecting code. When detected at end, replaced average corresponding lines.
