Title: Innovations by Amitabh Saran

Introduction

Amitabh Saran is a notable inventor based in Cypress, California. He has made significant contributions to the field of data compression and video processing. With a total of 7 patents to his name, Saran's work has had a considerable impact on technology.

Latest Patents

One of his latest patents is a circuit for compacting variable length data words into a fixed word length format. This innovative circuit separates each variable length data word and its associated leading zeros with a delimiter bit, storing them in memory. When accessed, the output word is loaded in parallel into a shift register, which strips the leading zeros and delimiter bit. The remaining data bits are then shifted serially into a second shift register, allowing for efficient compaction of variable length words into fixed length words. This technology is particularly useful for compacting variable length Huffman codes and can also serve as a character generator for raster scanned displays.

Another significant patent by Saran is a data decompressor circuit designed for decompressing video after prior compression for transmission or storage. This circuit operates on the assumption that the original video was processed by a raster input scanner and coded using run length encoding. The decompressor unpacks the data by joining together sixteen-bit data words and converting code words into decoded data. It inspects the actual video of the preceding scan line and the previous video bits to produce depredictor bits, ultimately generating the final actual video.
