Title: INTERACTIVE DISPLAY SYNCHRONISATION
Abstract:
A system (100) provides synchronised content between participants (20, 30) in a presentation (e.g. conference call) using a presenter component without the need to download and install additional software or plug-ins. A method for synchronising content between two or more digital content Tenderers (40) comprises: Receiving over a first communication channel a first communication indicating a change in content rendered on a first digital content renderer. Transmitting over the first communication channel to a second digital content renderer, a second communication indicating the change in content rendered on the first digital content renderer. Receiving over a second communication channel a request from the second digital content renderer for the changed content. Transmitting over the second communication channel to the second digital content renderer data enabling the changed content to be rendered on the second digital content renderer. A presentation layer (45) combines the two streams or tiers and provides the presenter with an interactive presentation or interactive canvas (40). The interactive canvas (40) enables the presentation of content elements, which are available and utilises specialist tools available from the application layer (60). This provides both presenter (30) and viewer(s) (20) the ability to interact with the presentation or interactive canvas (40), whilst ensuring that face-to-face audio and/or visual elements from the communication layer (50) can continue uninterrupted. The presentation layer (45) also ensures that the presentation or interactive canvas (40) remains in synchronisation for all parties and that the presenter (30) and viewer(s) (20) have a consistent view at all times. The presentation layer (45) resides on both or all end points (viewer or presenter). The communication layer (50) may include a cloud-based server hosted by a webRTC platform provider, for example. The application layer (60) may include a cloud-based server hosted by ISP, for example. The use of indicators and traffic light tools may inform the presenter (30) that the viewer's interactive canvas (40) is in sync with their own canvas.
