Wireless Video/audio Transmission Technology For Integrating Natively Portrait Display Hardware Into Landscape Mode HMDs With No Additional Latency
UPDATE: Next Generation Wireless Video Transmission Soon To Be Demonstrated 
Serious Simulations has worked for over 3 years to improve wireless video/audio/data transmission at low latencies.We’re soon to demonstrate another breakthrough in this unique and vital technology. Overcoming the limitations of previous attempts at wireless video transmission in terms of resolution and frame rate, our patent pending approach enables customization of resolution and frame rate to support customers’ unique needs and bandwidth allocations. Completely tailorable combinations of resolutions (up to 3K) and frame rates (up to 120 fps) with tiny processing latencies measured in nanoseconds and microseconds will soon be available. All of these transmissions are specifically designed to move frames of video completely uncompressed so as to maintain pristine quality and avoid dropped pixels or frames, and no additional latency from compression algorithms. Please contact Chris Chambers or Damon Curry at info@serioussimulations.com for further information for this pending technology availability.

Serious Simulations Ground Breaking Zero Frame Latency Reformatter™
The Reformatter™ enables makers of Head Mounted VR displays using 1080p screens and DVDO wireless links to receive and display images without any Frame Buffering, saving more than 17 milliseconds of latency.
Today, many HMD’s use cell-phone displays, which are natively Portrait, but today’s most widely used wireless video products only support Landscape format video signals. When a Portrait display is turned on its side (physically rotated 90 degrees), the incoming Landscape mode video images must also be rotated … and simultaneously converted to Portrait mode.
Without the Reformatter™, image rotation required buffering one frame of video, which displayed the screen by 16.7 milliseconds (at 60 frames per second video rate). Serious Simulations Reformatter™ does that rotation 1000 times faster, rotating the image as it is received.
The Reformatter™ can fill the screen with all displayed pixels in the same “frame time” as the image was received, so we call “Zero Frame Latency”. The bottom result: wireless VR at amazing speed!
This method is so fast it is literally a zero-frame latency procedure. Eliminating big chunks of latency greatly improves the VR experience, enhances the suspension of disbelief for better training or entertainment, and greatly reduces the chances of trainee or player discomfort.
General specifications of the system are:
HDMI input/HDMI out, HDMI input/MIPI output
Power Requirement: +5 volts DC, regulated
Electrical: Approximately 3.5 watts (700 milliamps at 5 volts) …includes power consume by the display screen and the headphone audio output
Compatible with 4-lane MIPI input displays (LCD, LED, OLED, AMOLED)
Reformatter™ converts 1080p 60Hz Landscape format HDMI signal to Portrait format in real time
Zero Frame Latency (no delay of frames)
Pixel latency within a single video frame: 20 microseconds maximum
Reformatter’s operation (pixel clock) phase-locked to incoming HDMI signal
Audio output (headphone level audio)
Burn-in Test: continuous operation at room temperature, 72 degrees minimum
