Abstract:
1. A method comprising: receiving, at a conference bridge, a plurality of media capabilities, the media capabilities comprising a media capability of each respective one of a plurality of conference devices in communication with the conference bridge, wherein the media capability indicates a video format that the respective one of the conference devices can encode and decode, designing, using the conference bridge, a media layering plan that is common to the conference devices, the media layering plan supports a combination of the media capabilities of the conference devices, and sending, using the conference bridge, a request to each respective one of the conference devices, wherein the request indicates an encoding scheme to use when the respective one of the conference devices is an active presenter, wherein the encoding scheme is based on the conference devices other than the respective one of the conference devices; receiving, at the conference bridge, an input media stream from an active presenter conference device included in the conference devices, wherein the input media stream includes media encoded consistent with the encoding scheme indicated by the request sent to the active presenter conference device by the conference bridge; converting, using the conference bridge, the input media stream into a plurality of output media streams, wherein each respective output media stream is associated with the respective one of the conference devices other than the active presenter conference device, and wherein each respective output media stream is converted to match the media capability of the respective one of the conference devices by removing a layer from the input media stream according to the media layering plan; and sending, using the conference bridge, each of the output media streams to the respective one of the conference devices other than the active presenter conference device.
