Abstract: A method of compensating for potential interruptions in a wireless connection (110) over which data is transmitted from a host device (11) to a client device (12) involves determining an expectation of an interruption to the wireless connection (110), setting a second compression level for compressing the data when an interruption is due, the second compression level being set at a higher level than a first compression level normally used for the data, compressing the data at the second compression level, and forwarding the data compressed at the second compression level to a transmitting component (16) for transmittal to the client device (12).

Abstract: A method of compensating for potential interruptions in a wireless spatially selective connection over which data at a first compression level is transmitted from a host device to a client device involves determining (S32) that an interruption to the wireless spatially selective connection over which data is being transmitted at a first compression level to a client device is starting or is due to start, compressing (S3Y3) the data at a second compression level that is higher than the first compression level, and forwarding (S34) the data compressed at the second compression level to a transmitting component for wireless spatially non-selective broadcast while the interruption to the spatially selective connection occurs. Determining that the interruption is due to start may involve analysing a historical record of previous interruptions to determine a periodicity of the previous interruptions or receiving information from the transmitting component that an interruption is expected to occur.

Abstract: A Virtual Reality or Augmented Reality (VR/AR) system includes a central control unit and a user display device. A method of processing visual information for display on the user display device involves comprising: determining (802) a first region and a second region of a frame of visual information, discarding (804) visual information corresponding to the second region of the frame, processing (806) visual information corresponding to the first region of the frame, obtaining (810) replacement visual information corresponding to the second region of the frame, displaying (812) the visual information corresponding to the first region of the frame on a first portion of the screen and displaying the replacement visual information on a second portion of the screen. The visual information of the first region of the frame is transmitted from the central control unit to the user display device subsequent to discarding the visual information corresponding to the second region of the frame.

Abstract: A method of generating display data at a display control device for display on a movable display involves receiving and storing a current frame of display data from a host device. The current frame is then processed and output for display on the movable display. Sensor data from sensors associated with the movable display is received and stored, the sensor data indicating movement and/or position of the movable display. If it is determined that a next frame of display data is not ready at the display control device for processing and outputting to the movable display at a required time, then an estimated next frame of display data is generated using the stored current frame and the stored sensor data and the estimated frame of display data is output for display on the movable display. The sensor data may be received either before or after the current frame is received, stored, processed or output.
