Low-Latency Transmissions for Remote Collaboration in Post-Production

The post-production often involves several key parties who want to be in the control of the process — the director, the producer, the editor, and several technical experts — the colorist, the stereographer, the sound master, etc. Some decisions are more effectively done in real-time, interactively. However, the participants are often very busy, working on multiple projects in parallel and it is difficult for them to travel together for a collaborative session. We believe that future technology for low-latency high-quality transmissions of image and sound will enable remote real-time collaboration in post-production. As the capacity of optical networks is increasing, uncompressed transmissions of original content with minimal latency will be possible. We did several experiments with real-time remote collaboration in color grading and stereography to over 10000 km between Europe and West Coast US, using GLIF (Global Lambda Interchange Facility) network. We describe the key technology aspects and lessons learned.
