Lattice Semiconductor, and TPCAST announced an exclusive partnership to deliver wireless solutions for Head Mount Display (HMD)-based VR systems. Lattice’s WirelessHD solution, along with a suite of FPGA and ASSP products, are offered exclusively in TPCAST’s VR applications which require low latency, high bandwidth wireless video transmission.

TPCAST’s protocol supports wireless transmission of HD display and feedback control for smart devices and computers. TPCAST’s newly released TPCAST 2.0 protocol supports up to 4K resolution at 120Hz, enabling an immersive wireless VR experience with near-zero latency transmission for both the display and controllers.

The TPCAST wireless upgrade kit includes Lattice’s MOD6320-T/MOD6321-R WirelessHD modules offering near-zero latency and robust Non-Line Of Sight (NLOS) performance suitable for VR applications. TPCAST’s solution also features Lattice’s SiI9396 600 MHz HDMI bridge IC, LatticeECP3 SERDES-based FPGA, and TPCAST 2.0 protocol and algorithm. Together, this robust solution supports wireless transmission of VR display resolution at 2160x1200 at 90Hz.

“Our partnership with TPCAST delivers optimised wireless video solutions, further validating our commitment to improving the virtual reality experience,” said Cheng Hwee Chee, Senior Director of marketing, mobile and consumer division at Lattice Semiconductor. “Our WirelessHD technology allows VR enthusiasts to eliminate cables while maintaining high-quality and robust video connectivity, without sacrificing performance.”

“When seeking a partner to collaborate on our wireless VR protocol TPCAST 2.0, Lattice’s proven WirelessHD technology, coupled with Lattice’s FPGA and ASSP products, was a natural fit,” said Andrea Liu, Marketing Director at TPCAST. “Working with Lattice, we’re able to deliver a truly unmatched VR experience with low latency, high robustness and high bandwidth video transmission. We look forward to continuing our work with Lattice to develop future wireless VR solutions.”

Lattice brings to market a range of millimetre wave solutions for high-speed wireless video and data transfers. Grounded on years of market leadership, Lattice delivers multi-gigabit data rates with fast responding beam forming ensuring high quality, low latency interactive video experiences. Lattice’s programmable logic devices are also used in many other VR and 360 camera applications such as display bridging, spatial and positional tracking and camera interface expansion.
