Title: The Innovative Contributions of Damien Gerard Saint Macary

Introduction

Damien Gerard Saint Macary is a notable inventor based in Sunnyvale, CA. He has made significant contributions to the field of graphics data processing, holding a total of 7 patents. His work focuses on enhancing the efficiency and fidelity of graphical data transmission, particularly in remote presentation sessions.

Latest Patents

One of his latest patents is titled "Transform Space Difference Compression." This invention involves performing differencing of graphical data in post-transform space for remote presentation sessions. The graphical data is transformed from a first representation to a second representation, such as with a Discrete Wavelet Transform (DWT). A difference is then taken of the post-transform data and the preceding frame's data. This difference is encoded and transmitted to a client, which decodes it to create a representation of the graphical data using the delta and a previously determined representation of the previous frame. By performing differencing in post-transform space, the fidelity of the remote presentation session is retained while potentially decreasing bandwidth usage.

Another significant patent is "Real-Time Compression with GPU/CPU." This patent provides techniques for efficiently processing and transmitting graphics data when sub-regions of the screen are updated at different rates. In this embodiment, the screen is divided into tiles, and when certain tiles are determined to have changed, some of the sublevels resulting from the image transform may not be encoded and transmitted. The decoding process can use zeroes for any data not received, allowing the rendering subsystem to render the image with partial data while the remaining data is received in subsequent transmissions.
