Abstract

Enabling a sink device e.g. display monitor, to stream audio/visual content to a source device e.g. CPU or GPU, 152 over a display interface; and enabling the sink device to receive audio/visual (AV) and/or input/output (I/O) information from a source device 154 and to transmit AV and/or I/O information to a source device 156 over the display interface. DisplayPort(RTM) topology may be managed in the presence of sink devices that can stream A/V content to the source device, or can receive or transmit I/O information from/to the source device. This I/O information may include raw sensor data for a touch screen. The framework could be used to support or map other published I/O interface standards, over DisplayPort(RTM) interface. A high bandwidth receive path can be configured in the topology independent of the transmit path to support inbound I/O and AV functions. Both isochronous and bulk I/O transfers and inbound A/V can be supported.
