Interconnection mechanism for multiple data streams

摘要

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.

主权项

1. A system comprising a processor executing instructions stored in a non-transitory machine-readable memory to provide:
a source node configured to send a video stream to display nodes through a network, the source node further comprising: a network controller logic that is configured to receive source control information from a stream manager, wherein the source control information specifies an interchange format and a first segment and a second segment of a video stream to be sent to a first and a second display node to show on adjoining displays served by the first and second display nodes; a streaming logic that is configured to convert the first and second segments of the video stream from a native interchange format to the interchange format and to send only the first segment to the first display node and to send only the second segment to the second display node to show at positions, specified by the stream manager, on the adjoining displays, where the first and second segments are converted from the interchange format into a displayable interchange format in the first and second display nodes; and an area of interest processor configured to decompose the video stream into the first and second segments.
