A system and method for transmitting compressed video. A transmitter receives uncompressed video data from a video source, and compresses it using one or more reference frames. A receiver receives the compressed video data and decodes it, using the same reference frames, to form display data. The reference frames are stored in compressed form in both the transmitter and the receiver. Each frame of display data becomes a reference frame for the decoding of a subsequent frame.

A unified visualization interface is disclosed. One example is a system including an association module, a multicasting module, a data sharing module, and a unified visualization interface. The association module associates an identified event in a first visualization system with a visualization function. The multicasting module stores event data related to the identified event and the associated visualization function in a shared data source, and multicasts the identified event to a second visualization system. The data sharing module associates the event data with characteristics of the first visualization system, and shares, in response to the multicast of the identified event, the shared data source with the second visualization system. The unified visualization interface automatically invokes, without software changes, the second visualization system in response to the multicast of the identified event, the invoking based on the shared data source including the characteristics of the first visualization system.
