User interface for video observation over the internet

We present the design and application of a system for live video transmission and remote camera control over the World Wide Web. Extensive testing of the Internet Video Server IVS prompted us to improve its user interface.

Once the view is selected the users prompts the selection and the command is issued over the Internet to the remotely controlled camera.

This work was supported by the Ministry of Science and Technology of Republic of Slovenia Project L2-8721 and by the European Cultural Mont...
