A controller has a basic GUI formed of HTML5 and Javascript including elements to control a system as a whole. The controller receives GUI HTML5 and Javascript from each connected hardware module, such as a camera, microphone, lighting controller and the like. The controller adds the received HTML5 and Javascript from each hardware module to the base code and sends the combined GUI to the user. Data is returned from the user to the controller and then forwarded to the proper hardware module.

Method for providing seamless graphical user interface control for a complex system consisting of distributed hardware modules

Disclosed are example embodiments of a method and system to reduce re-transmission requirements of a compress media transferring system implemented in a network where packet loss could be possible. An extended header for each transmitted packet can indicate the priority of the packet and endpoints can determine if a re-transmission of a missing packet is desired. Buffering of packets at different hops in a multi-hop system could allow for the retransmission request to be satisfied by a more recent hop than the original system transmitting the video packet. In one embodiment three levels of priority are established to achieve a reliable frame rate of 30 frames per second by compressing the first and second levels at 7.5 frames per second and a third level at 15 frames per second.
