Abstract: There is provided a method comprising: allocating each user participating in a multi-user call to a first group, a second group, or a third group in dependence on a respective first priority associated with each user; causing a display to render image data representative of respective users in the first group in a primary area of the display and to render image data representative of respective users in the second group in a secondary area of the display, wherein users in a third group do not have image data rendered in either of the primary and secondary areas; and re-allocating each user participating in the multi-user call to the first group, the second group, or the third group in dependence on a respective second priority associated with each user, such that users immediately previously allocated to the third group are not re-allocated to the first group.

Abstract: A device comprising: a display; an interface configured to exchange video data between the device and a network during a video call between a user of the device and at least one further user; a memory storing information identifying at least one display element each associated with one of the at least one further user; and a processor configured to run a client application operable during the call to: display received video in a first UI window on the display; detect the user navigating to a second UI window comprising one of the at least one display element; query the memory to determine a location for the display of the received video, and in response, display the second UI window and control the video received from the further user associated with the display element of the second user interface window to be displayed at a location of the display element.
