Abstract: A sink device in a Wireless Display (WD) system may establish a user input device control communication channel between a source device and sink device in a WD system to allow the sink device to send device control inputs to the source device. The user input device control communication channel may include a reverse channel architecture referred to as the Wi-Fi User Input Back Channel (UIBC) that has been modified to transport one or more additional input types over UDP. For example, UIBC may be extended to transport voice input and VNC input types.

Abstract: Source and sink devices are adapted to facilitate streaming of screen content data over a USB communication channel. According to one example, a source device can capture GPU-executable video data at an input of a GPU, and transmit a graphics domain data frame including the captured video data on a data plane of a USB communication channel. Further, a command message may be transmitted on a management plane of the USB communication channel. The sink device may receive the graphics domain data frame with the captured video data on the data plane, and may receive the command message on the management plane. The sink device may render and display the video data. Other aspects, embodiments, and features are also included.

Abstract: The disclosure provides methods, apparatus, and computer-readable medium for setting parameters pertaining to service period (SP) for reduced latency in wireless communication. The apparatus may determine whether an amount of data at a medium access control (MAC) layer at the apparatus exceeds a maximum amount of data transmittable in a single transmission opportunity (TXOP). If so, the apparatus sets a duration of the SP for transmission of the data to be greater than or equal to a duration required for transmitting the data, and the apparatus transmits the data during the set duration of the SP. The apparatus may also set a duration of a service period interval (SPI) to be greater than or equal to the duration of the SP and less than or equal to a duration for transmitting the data using the single TXOP. The data may be latency-sensitive data, such as isochronous data or interrupt data.

Abstract translation: 本公开提供了用于设置与服务周期（SP）有关的参数的方法，装置和计算机可读介质，用于减少无线通信中的等待时间。 设备可以确定设备处的介质访问控制（MAC）层的数据量是否超过在单个传输机会（TXOP）中可发送的最大数据量。 如果是这样，则设备将用于传输数据的SP的持续时间设置为大于或等于发送数据所需的持续时间，并且设备在SP的设置持续时间期间发送数据。 该设备还可以将服务周期间隔（SPI）的持续时间设置为大于或等于SP的持续时间，并且小于或等于使用单个TXOP发送数据的持续时间。 这些数据可能是延迟敏感数据，如同步数据或中断数据。

The first device may determine whether a profile of a second device matches a profile stored in the first device. When such a match exists, the first device may export data to the second device in a format associated with the profile of the second device. When such a match does not exist, the first device may provide an error message or export data to the second device in a format associated with a default profile of the first device. The profile may indicate an operating system, a peripheral component, a display size, a display resolution, a touch screen-capability, a font type, a user setting, a power source or availability, a hardware component, or a software module.
