Image compression and transmission for heads-up display (HUD) rehosting
A heads-up display (HUD) rehosting apparatus is disclosed. In embodiments, the HUD rehosting apparatus includes graphics processors for generating HUD display imagery and a primary display unit or display surface. The HUD rehosting apparatus includes an image capture module for grabbing the displayed HUD images and compressing the images into image data frames via run-length encoding. The compressed data frames are transmitted to secondary rehosting devices capable of decoding the image data and displaying the HUD imagery, e.g., projected onto additional surfaces or via wearable devices.
1. A heads-up display (HUD) apparatus, comprising:
one or more graphics processors configured to generate at least one display image;
a main heads-up display (HUD) unit operatively coupled to the one or more graphics processors, the main HUD unit configured to display the at least one display image to at least one user;
and
at least one capture module in communication with the graphics processors, the capture module configured to:
generate one or more data frames by compressing the generated display image according to at least one run length encoding (RLE) algorithm;
and
transmit the generated data frames to at least one rehosting device according to at least one network protocol.
2. The HUD apparatus of claim 1 , wherein:
the at least one rehosting device includes at least one of an augmented reality (AR) viewer and a virtual reality (VR) viewer.
3. The HUD apparatus of claim 1 , wherein the one or more data frames generated by the capture module includes at least one display image compressed into a single data frame.
4. The HUD apparatus of claim 1 , wherein the one or more data frames include at least one of a TCP network frame and a UDP network frame.
5. The HUD apparatus of claim 1 , wherein the at least one display image is a monochrome image.
6. The HUD apparatus of claim 1 , wherein the capture module is configured to transmit the generated data frames to the at least one rehosting device via at least one wireless network protocol.
7. The HUD apparatus of claim 1 , wherein:
the apparatus is embodied within a vehicular simulator configured to emulate the cockpit of a vehicle;
and
the display unit is located at a first location within the vehicular simulator;
and
the at least one rehosting device is located at a second location within the vehicular simulator.
8. The HUD apparatus of claim 1 , wherein the rehosting device is a first rehosting device configured to transmit the generated data frames to at least one second rehosting device according to the at least one network protocol.
9. A heads-up display (HUD) rehosting apparatus, comprising:
a receiver module configured to:
receive one or more data frames according to at least one network protocol;
and
generate at least one display image by decoding the one or more data frames according to at least one run-length encoding (RLE) algorithm;
and
a HUD display device in communication with the receiver module, the display device configured to present the at least one display image to at least one user.
10. The HUD rehosting apparatus of claim 9 , wherein:
the apparatus is embodied within a vehicular simulator configured to emulate a moving vehicle;
and
the display device includes a projector configured to project the at least one display image onto at least one interior surface of the vehicular simulator.
11. The HUD rehosting apparatus of claim 9 , wherein the display device includes at least one of an augmented reality (AR) viewer and a virtual reality (VR) viewer wearable by the user.
12. The HUD rehosting apparatus of claim 9 , wherein the rehosting apparatus is a first rehosting apparatus and the receiver module is configured to transmit the one or more data frames to at least one second rehosting apparatus according to the at least one network protocol.
