Finding a balance between the bandwidth reduction, the resulting compression artefacts and the artefact correction methods will be done differently by every remote desktop application, for this reason, different applications can favour different workflows. In order to improve perceived picture quality, remote desktop software often utilizes a palette of techniques to correct or mask the compression artefacts. The compression of the signal will in most cases introduce compression artefacts, which are the result of it being reduced to a more manageable and responsive scale for use over the internet. In order for remote desktop software to achieve as responsive a connection as possible, even with a low-speed Internet connection, the bandwidth of the transferred signal must be kept to a minimum. The remote computer in turn sends the picture in the form of bitmap updates (pixel values) back to the client to be displayed. How does it work?Ī local computer, commonly referred to as the client, can use remote desktop applications to send commands to the remote computer, referred to as the server. Due to the outbreak of COVID-19 there has been an increased push toward the implementation of home office workflows, which in turn has brought wider attention to tools such as TeamViewer and many others, all of which suit particular business and personal needs in different ways. The popularity of these applications has steadily increased over the years because they allow for both the centralization of computer hardware within a company and location-independent access to it through the Internet. Remote desktop applications allow for remote control of a computer though the network.
