Abstract: In one embodiment, an apparatus includes a port comprising circuitry to couple the apparatus to one or more devices over a DisplayPort (DP)-based link and a processor to generate signals for communication over the DP-based link. The apparatus also includes memory with instructions to cause the processor to initiate a transition to a low power state in devices of the DP-based link by transmitting a sleep pattern signal over the DP-based link, and initiate a transition to an active power state in devices of the DP-based link by transmitting a wake pulse sequence and physical link establishment signal pattern over the DP-based link.

Abstract: Technology for a display controller is described. The display controller can detect a frame update when the display controller is in a dynamic sleep state. The display controller can wake up from the dynamic sleep state and enter a selective update state at a programmed vertical blanking interrupt (VBI) that precedes an actual VBI. The display controller can perform a scan-out with a display panel during the selective update state. The display controller can return to the dynamic sleep state in a same time frame after the scan-out is completed. The display controller can exclude timing logic to send a VBI at every time frame to the display panel to maintain time synchronization between the display controller and the display panel.

Abstract: Techniques related to providing video on a variety of transports are discussed. Such techniques include transmitting and receiving separate first and second video streams such that a first video stream includes a base frame of composed video content and the second video stream includes a user interaction frame of user interaction content and, after receiving the video streams, combining the base frame and the user interaction frame to generate a composite frame for presentment by a display.

Abstract: Methods, apparatus, systems and articles of manufacture to reduce power consumption and improve battery life of display systems using adaptive sync are disclosed. An example apparatus includes an interface to transmit frame data to a sink device, the frame data generated by a processor; a timer to initiate in response to the transmission of the frame data to the sink device; and the interface to transmit a low power indication to the sink device after the timer reaches a threshold amount of time.

Abstract: Embodiments include apparatuses, methods, and systems including a selector. A selection signal may be provided to the selector to select a first synchronization signal as a control signal when the first synchronization signal is available, otherwise a second first synchronization signal as the control signal. The first or the second synchronization signal may synchronize a first or second display content received by a first or second display device with a first or a second display refresh rate, respectively. The control signal may be provided to a controller to control the second display content received by the second display device. Other embodiments may also be described and claimed.

Abstract: Systems, apparatuses and methods may include a source device that generates a scene change notification in response to a movement of a camera, modifies an encoding scheme associated with the video content captured by the camera in response to the scene change notification, identifies a full-frame difference threshold, wherein scene analysis information includes frame difference data, and compares the frame difference data to an intermediate threshold that is less than the full-frame difference threshold, wherein the scene change notification is generated when the frame difference data exceeds the intermediate threshold. A sink device may obtain transport quality data associated with video content, modify an output parameter of a display based on the transport quality data, determine a view perspective of a still image containing a plurality of image slices, retrieve only a subset of the plurality of image slices based on the view perspective and decode the retrieved subset.

Abstract: A system for reducing bandwidth and/or reducing power consumed by a display may comprise a display having a background plane and a region of interest plane that may be identified by a gaze tracker. The region of interest may be of a higher quality picture. In some embodiments, the display may be a large panel display and in others a head mounted display (HMD).
