Abstract

VCenter, a platform for broadcasting digital video content, was developed by the National Digital Archives Program (NDAP), Taiwan. The platform provides a number of functions, such as digital video archiving, format transformation, streaming broadcasts, editing, geotagging, and blogging. The concept of Web2.0 is conducted in VCenter to increase user participation and improve interaction between the system and the user.

For videos, VCenter adopts Flash technology because it has a multi-layer architecture and it can handle multimedia content. We can add watermarks or captions as layers to videos without changing the original video’s content so that when users browse videos, the multi-layer overlaps the original video layer in real-time.

VCenter serves the Union Catalog system of NDAP as a video broadcasting platform. In addition to archiving the valuable videos of NDAP, it allows the general public to archive, broadcast, and share digital videos.
