Abstract: An electronic device is configured to determine apart (161) of a light effect for a first period and determine a succeeding part (186) of the light effect for a second period succeeding the first period. The electronic device is further configured to determine a likelihood that a second original light command specifying a part (162) of a light effect for the second period will not arrive at its destination and transmit an original first light command or determine and transmit an alternative first light command in dependence on the likelihood and/or the determined succeeding part of the light effect. The original first light command specifies the part of the light effect and the alternative first light command is determined based on the part and the succeeding part of the light effect and specifies a portion of the light effect for both the first period and the second period.

Abstract: The invention relates to a lighting device which is operable in two modes. In a first operating mode the flux of a lighting effect having a specified chromaticity is rendered based on the maximum (luminous) flux at which the chromaticity can be rendered by the lighting device. This can cause the maximum (luminous) flux across a range of colors that the lighting device can render to vary greatly. For example, a white color may be rendered at a far greater intensity than a primary color. In a second operating mode the specified chromaticity is rendered based on a predetermined maximum (luminous) flux for that specified chromaticity, or a color range that it is comprised in, or a predetermined maximum (luminous) flux for one or more color channels that are used in combination to render the light effect. This reduces the differences in maximum (luminous) flux of lighting effects rendered across the range of colors that are rendered by the lighting device.

Abstract: An electronic device is configured to identify a dynamic light scene (81) to be rendered, determine one or more current, previous and/or planned light settings (91, 92) for one or more lights (22, 23), determine a target dynamic light scene (83) based on said identified dynamic light scene and said one or more light settings, and render said target dynamic light scene on at least one light (22, 23).

Abstract: A method comprises obtaining (101) media content information and obtaining (103, 109) information indicating a degree of speech in the audio portion. The media content information comprises the media content and/or information determined by analyzing the media content and the degree of speech is determined based on an analysis of an audio portion of the media content.

Abstract: The invention relates to a connected device system that is adapted to form a low-bandwidth wireless mesh network (2) between a plurality of devices (3, 4, 5, 6). The connected device system (1) comprises multiple output devices (3, 4, 5) for outputting human-perceptible stimuli and a controller device (6) for controlling the stimulus outputs of the multiple output devices via the wireless mesh network. The controller device is adapted to switch a group of the multiple output devices from a first control mode, in the stimulus outputs are controlled by control messages of a first type, to a second control mode, in which the stimulus outputs are controlled by control messages of a second type. The control messages of the second type are transmitted to the output devices of the group at a higher rate than the control messages of the first type.

Abstract: In a wireless mesh network, a battery operated node can select a parent node via which messages are routed to further nodes. The parent node can initially be selected based on signal strength. The node receives acknowledgements for messages sent, if they arrive. The node calculates a reliability indicator of the parent node based on the number of messages for which an acknowledgement has been received. If the reliability indicator exceeds a predetermined threshold the node selects a new parent node, based on second selection criteria. For example, the node with the next greatest signal strength.

Abstract: A lighting system controller, a lighting system control method and software program product are provided for controlling a lighting device based on a trigger signal, such as a presence detection signal from a presence sensor. Instead of switching the lighting device to a fixed light setting at all times when the trigger signal is received, the initial light output of the lighting device is determined. The lighting device is then controlled according to a fixed light setting (e.g. white light at full brightness) if the determined initial light output is within a predetermined range, and else it is controlled according to a function relative to the determined initial light output. For example, if the lighting device is participating in a romantic scene emitting predominantly red light the lighting device may switch to reddish white light instead of the full white light and/or the brightness level of the light is lowered compared to the fixed light setting.
