Real-time long-distance transfer of uncompressed 4K video for remote collaboration

摘要

Better-than-high-definition-resolution video content (such as 4K) is already being used in some areas, such as scientific visualization and film post-production. Effective collaboration in these areas requires real-time transfers of such video content. Two of the main technical issues are high-data volume and time synchronization when transferring over an asynchronous network such as the current Internet. In this article, we discuss design options for a real-time long-distance uncompressed 4K video transfer system. We present our practical experience with such transfers and show how they can be used to increase productivity in film post-production, as an application example.
