US 12,148,354 B2 · Spread-spectrum video transport integration with virtual reality headset

Abstract

A video stream is encoded using spread spectrum video transport and sent as an analog signal to a display of a VR visor where a decoder integrated with a source driver decodes the analog signal and drives the display. The analog signal is sent wirelessly to the display where it is received, converted to wired format, decoded and displayed. A wireless SSVT analog signal is received at the headset processor and forwarded to the VR visor for reception, conversion, decoding and display. A wireless SSVT analog signal is received at the processor, converted to wired format, sent wirelessly to the display where it is received at a receiver, converted to wired format, decoded and displayed. A video stream is stored in persistent storage on the headset processor using SSVT encoding. The decoder integrated with a source driver of a display is implemented directly on the glass of the display panel.

Dependent claims

A virtual reality (VR) headset comprising:

a headset processor including a transmitter arranged to receive a stream of video samples, to continuously encode sets of N of said video samples each into a set of L output levels, and to transmit said sets of L output levels as an analog waveform over an electromagnetic pathway, wherein L>=N>=2;
and
a VR visor including at least one display having at least one source driver, said source driver including
a receiver arranged to receive said sets of L output levels of said analog waveform from said transmitter,
a decoder arranged to decode each set of said L output levels into an output vector of N analog samples,
a buffer arranged to collect said output vectors of N analog samples each from said decoder, and to output said output vectors of N analog samples in parallel, each of said analog samples being output to a column of said display, wherein said analog samples corresponding to said stream of video samples are substantially displayed on said display.
