Introduction

Jean Mary is a notable inventor based in Orsay, France. He has made significant contributions to the field of digital broadcasting, holding three patents that showcase his innovative spirit and technical expertise.

Latest Patents

Jean Mary's latest patents include a method of making up a digital multiplex and an apparatus implementing said method. This method is designed for generating a digital multiplex signal for broadcasting. The multiplex consists of packets of determined length coming from various sources, utilizing treatments selected from a catalog of stored treatments. It is applicable to D2-MAC/packet and digital TV. The encoder implementing this method features sources that insert the identity of the treatment to be performed into a designated field in each packet precursor. Downstream from the sources, the encoder includes a treatment unit for decoding the field and applying the specified treatment.

Another significant patent is a modular encoder for generating a digital multiplex signal and decoder. This X-MAC encoder allows for the encoding of multiple components, each with a sequence of packets distributed in successive bursts that occupy a predetermined fraction of a television frame line. It comprises several blocks, each containing at least one packet encoder with a buffer memory for storing digital data from a source. The encoder distributes packets in bursts of adjustable duration, not exceeding the duration of one television line. A base encoder assembly features a programmable device that allocates a specific window of the television frame to each block, calling a burst of length corresponding to the allocated width at the beginning of each window in a line.
