摘要： A system that includes a head mounted display device and a processing unit connected to the head mounted display device is used to fuse virtual content into real content. In one embodiment, the processing unit is in communication with a hub computing device. The processing unit and hub may collaboratively determine a map of the mixed reality environment. Further, state data may be extrapolated to predict a field of view for a user in the future at a time when the mixed reality is to be displayed to the user. This extrapolation can remove latency from the system.

摘要： Versions of a multimedia computer system architecture are described which satisfy quality of service (QoS) guarantees for multimedia applications such as game applications while allowing platform resources, hardware resources in particular, to scale up or down over time. Computing resources of the computer system are partitioned into a platform partition and an application partition, each including its own central processing unit (CPU) and, optionally, graphics processing unit (GPU). To enhance scalability of resources up or down, the platform partition includes one or more hardware resources which are only accessible by the multimedia application via a software interface. Additionally, outside the partitions may be other resources shared by the partitions or which provide general purpose computing resources.

摘要： Independently processing planes of display data is provided by a method of outputting a video stream. The method includes retrieving from memory a first plane of display data having a first set of display parameters and post-processing the first plane of display data to adjust the first set of display parameters. The method further includes retrieving from memory a second plane of display data having a second set of display parameters and post-processing the second plane of display data independently of the first plane of display data. The method further includes blending the first plane of display data with the second plane of display data to form blended display data and outputting the blended display data.

摘要： A depth-mapping method comprises exposing first and second detectors oriented along different optical axes to light dispersed from a scene, and furnishing an output responsive to a depth coordinate of a locus of the scene. The output increases with an increasing first amount of light received by the first detector during a first period, and decreases with an increasing second amount of light received by the second detector during a second period different than the first.

摘要： Systems and methods for compositing an image directly from multiple source image data for reducing system memory footprint and bandwidth and for improving color quality of the image. The image is divided into spans, lines, and slices. Each line includes at least one span and each slice includes at least one line. All lines in a slice have spans associated with identical sources. An image is composited by reading the image data directly from one or more sources of each span. If necessary, the sources are blended. A control structure is used to provide the image context and identifies the sources of the spans. The control structure includes headers for each data stream from each source of each span. Also, the color quality of the image is improved by reducing the number of color space conversions that occur as the image is composited. All sources in the same color space are blended, before being blended with sources from other color spaces. Preferably, no more than a single color conversion is required.

摘要： Systems and methods for transcoding a transport stream or a video stream. A video stream includes a quantization matrix and a quantization scale that define how DCT frequency coefficients are quantized. A transport stream is transcoded by updating the quantization matrix and/or the quantization scale such that a new set of DCT frequency coefficients may be generated. Typically the quantization scale and/or the quantization matrix are updated such that the DCT frequency coefficients are more coarsely quantized such that their encoding consumes fewer bits. The quantization matrix can be updated such that select frequency coefficients are affected. Transcoding can operate at any level of the video stream, such as the frame level, the slice level, or the macroblock level. The bit rate of the video stream can therefore be adjusted or altered according to a current quantization level and a current bit rate.

The method includes receiving data relating to a first user interaction with a device in a multimedia system. The method includes determining if the first user interaction corresponds to a user's intent to interact with the device. The method then includes setting a power level for the device based on the first user interaction. The method further includes receiving data relating to a second user interaction with the device. The method then includes altering the power level of the device based on the second user interaction to activate the device for the user.
