Title: Innovations by Rickard Sjöberg

Introduction

Rickard Sjöberg is a notable inventor based in Tumba, Sweden. He has made significant contributions to the field of data compression and encoding methods. With a total of 2 patents, his work has implications for improving data transmission efficiency.

Latest Patents

One of Rickard's latest patents is a method of compressing data by using a self-prefixed universal variable length code. This method involves formatting a first set of code words for data and constructing a second set that includes code words from the first set as well as concatenations of those code words. The second set is designed to carry data in a compressed form within a digital bitstream. The process includes selecting a code word from the first set to serve as a prefix, which may be the shortest code word available.

Another significant patent is focused on alternative block orders for maximizing the prediction utility of previously encoded macroblocks. This method adjusts the scanning order of blocks within a macroblock to enhance the encoding process. It allows for maximum utility of previously encoded blocks located to the left of the macroblock being encoded, especially when no previously encoded blocks are available above it. The scanning order can be signaled either implicitly or explicitly, depending on the encoding context.
