An audiovisual signal is converted from a native format to a digital, packetized interchange format and transported between a capture node and a display node through a switch. The display node converts the audiovisual signal from the interchange format to a displayable format and causes display of the audiovisual signal. The use of a switch for video routing and distribution allows one-to-one, one-to-many, many-to-one, and many-to-many distribution. The use of a device-independent interchange format allows concurrent distribution of multiple heterogeneous audiovisual signals.

Interconnection mechanism for multiple data streams

The technology disclosed relates to enabling smooth transitioning between compressed video streams. In particular, it relates to scheduling transitions between compressed video streams to be shown in an area of a display such that while decoding, decompressing and buffering a first video stream for display, commencing decoding, decompressing and buffering of a second video stream at a predetermined time before a scheduled showing of the second video stream. It further relates to switching buffers between display of the first and second video streams at the scheduled showing of the second video stream, which results in immediate display of the second video stream without delay. In one implementation, switching between the buffers for the first and second video streams includes modifying z-ordering of display layers corresponding to the first and second video streams.

Systems and methods of smoothly transitioning between compressed video streams

Video data streams are routed between capture nodes and display nodes connected to one another through a high-bandwidth network switch and controlled by a stream manager connected to the switch. The stream manager negotiates a highest quality stream that can be processed by both the capture node and the one or more display nodes receiving the stream and that does not exceed available bandwidth through the switch. The stream manager includes a user interface by which a user can specify which of a number of video signals is to be displayed in what position within a display wall.
