Method and system for determining encoding parameters of video sources in large scale video surveillance systems

The present invention relates to improving configuration of wireless communication paths between devices in a video projection system comprising multiple wireless video projectors. When an initial radio communication setup is required between a managing node, e.g. a node comprising a master projector, and a node comprising a slave projector, for example following the powering up of the video projection system, the slave node receives setup information by radio communication means according to a sweeping sequence and transmits information by projecting sub-images. Sub-images advantageously comprise information relative to settings of the master node allowing reception in the corresponding slave node of a radio signal transmitted by the master node.

An antenna system having a cylindrical electromagnetic lens configured to guide at least one electromagnetic signal to an emerging area by means of at least a variation in dielectric permittivity, thereby generating a beam output from the emerging area. The antenna system has a dielectric member configured to receive the beam output from the emerging area and to focus the beam in an elevation plane perpendicular to a planar face of the cylindrical electromagnetic lens. The cylindrical electromagnetic lens is received in a conductive mounting, and the mounting carries the dielectric member.

Antenna system

A video projector, a cluster of video projectors and a method for wirelessly transmitting image data within the cluster of video projectors. The video projector includes a first antenna located at a first side of the projector and a second antenna located at a second side of the projector, opposite to the first side. Image data is divided into sub-parts, and distributed by assigning each image data sub-part to a video projector. A video projector receiving image data sub-parts extracts and stores the image data sub-part assigned to it, and retransmits image data sub-parts assigned to respectively a second and third video projectors.

Video projector and associated data transmission

A method is proposed for synchronizing a data stream transmitted on a communications network, the data stream being transmitted from an emitter device to a receiver device in the form of data packets of predefined size, a data packet being filled up with a padding synchronization symbol if an amount of applications data to be transmitted in the data packet is below the predefined size of the data packet. The receiver device performs the following steps:

A method of transmission of at least one data content by a source node associated with a generator application to at least one destination node, each associated with a consumer application, in a communications network comprising a plurality of nodes, each being associated with an application, the network implementing a first clocking which defines a first cycle, called a network cycle, for data transmission on said network. Each node of the network implements a second clocking which defines a second cycle, called a local cycle, for data transmission between the node of the network and its associated application, the network cycle being equal to an integer multiple P, P&#x2267;1, of the local cycle, the start of the network cycle coinciding with the start of a local cycle, the local cycle comprising a plurality of virtual channels corresponding to time slots, a set of the virtual channels being assigned to the transmission of the content or contents.

A transmit mode performs indirect synchronization with a master node for accessing a medium, in a synchronous communications network comprising a plurality of slave nodes capable of accessing the medium during access time slots. The indirect synchronization includes receiving at least one frame coming from at least one of the slave nodes of the network. From each frame received, synchronization information pertaining to a level of synchronization of the slave node having sent the frame is obtained, the level of synchronization of the slave node being relative to the master node. A reference node is selected from among the at least one of the slave nodes from which at least one frame has been received, as a function of the pieces of synchronization information, the transmit node being indirectly synchronized with the master node via the reference node.

A method of transmitting data in a synchronous communications network, which includes multiple nodes, includes communicating a super frame that includes multiple frames, based on a network cycle, each frame being associated with one of the nodes. Each frame includes a payload that includes an own data section and a repeat data section. The nodes include at least one relay node associated with an application generating own data of the relay node to be transmitted to at least one second node. The relay node receives frames from other of the nodes, reads a predetermined part of data from the received frames, which enables repeat data to be obtained, writes the repeat data in the repeat data section of a new frame, writes the own data of the relay node in the own data section of the new frame, and transmits the new frame.
