ABSTRACT
The note or the paper manuscript is established as a simple and fast tool for postprocessing presentations and meetings. This workflow is widely accepted because of its feasibility and availability. But analog paper notes are incompatible with ubiquitous acquisition and distribution, this means an interruption with today's media comprehension and a hurdle for later accessibility of content. The analog media of paper has reorganization and search limitations, especially for the later postprocessing of lectures. The combination of annotations on paper from different audiences is an other problem. It's difficult to handle and it's therefore only rarely used. Synergy opportunities are often lost. The development of recent digital tools for collaboration needs to be promoted to take advantage of collaborative sharing of knowledge. Nowadays video recording systems are used in lectures. This allows the later usage and postprocessing of the recorded lectures. By distributing these multimedia data via the internet, users can select the time and location for viewing. This is a key feature of E-Learning media. In this context, audio-visual media need to be afforded special attention for the collaborative learning of students. The web-based application described in this research paper offers an efficient solution for the collaborative production and also later the collaborative usage and supplementation. The value of lecture recordings increase with annotations and a comprehensive repository accrues. The repository can grow within a short time because of its collaborative development character. Therefore, it can deliver more information than a single person could acquire with paper and pencil within the same time. The paper presents a detailed insight into the implementation of the web tool and an analysis of first application scenarios.
