The Video Browser Showdown uses a server (DRES), which is responsible for two things:

• presenting all tasks on the projector
• collecting and evaluating all submissions of the participant’s systems

The DRES Server uses an HTTP protocol for communication with all VBS systems (see Communication with DRES). Every submission is compared against the ground truth (or evaluated by live judges, if there is no ground truth, such as for some AVS tasks).

Please cite corresponding papers when using the server.

Tasks from previous VBS competitions can be downloaded from this GitHub repository.
