Foreword

The history of computer-aided communication, which supports not only text video and sound goes back to the 1990s. From from today’s perspective, it seems almost grotesque what prices had to be paid for the had to be paid for the hardware developed at that time. Not only for the quality and quality of encoded data streams, new formats had to be invented (CIF (CIF, QCIF). The development of Codex was in its infancy. infancy. There was a lack of standardization. Interoperability and and the use of the Internet were at best distant goals. People were working on very application-specific solutions and approaches that had the potential for affordable components for mass production. As an example, the pioneering manufacturer Parallax Graphics Inc.. Founded in 1982 by two graduates of Cornell University, the company focused on the marketing of the marketing of high end graphics cards, including for the then popular university environment at the time. These cards initially cost around €25,000 and supplied ASICS and a codex implemented in implemented in hardware, which could realize resolutions of up to 1280x1024 pixels could be realized.

Every commercially available cell phone, tablet, notebook and desktop PCs currently deliver graphics card performance that can render 2k, even 4k pixels can render. Encoding and decoding solutions are decoding solutions have been standardized internationally, which have significantly reduced the bandwidths to be transmitted and thus and thus enable billions of uses on the Internet use on the Internet. One-to-one video telephony has been established for years. established for years. And everyone will remember the radical upheaval in the professional use of video conferencing solutions that the COVID pandemic brought with it in 2022.

Today, the use of video conferencing solutions is ubiquitous. In the working world, proprietary solutions are often used, to implement work processes regardless of location. Examples include the products from the manufacturers CISCO->(Webex), Microsoft->(Skype,Teams), HP->(Poly) and Zoom->(Zoom) are listed. But also free software such as BigBlueButton, Jitsi or Nextcloud->(Talk) are enjoying worldwide distribution.

With Element-Call the Matrix ecosystems gains a new approach that fully embraces the potential of MatrixRTC. Think of participents in decentralized domains that are to able to dynamicly create and manage multipoint meetings in an efficiant manner. An Open-Source, that enables fee choice of any Matrix complient Client. What progress.
