Wireless Video Streaming
I implemented a high-bandwidth video streaming pipeline between smart glasses and a smartwatch using Ixana’s custom YR22 silicon. This project leveraged Electro-Quasistatic (EQS) human body communication, transforming the wearer's body into a secure, ultra-low-power data bus to improve the power efficency compared to traditional wireless technologies like Bluetooth or Wi-Fi.
​
While I worked on the entire stack, from video capture at the smart glasses, to compression, transmission, decompression, and eventually displaying on the smart watch I was primarily responsible for writting the watch display drivers.
Technical Highlights
-
Bare Metal Development: Designed a power-efficient, bare-metal core OS in C++ for Ambiq and NXP ARM MCUs, managing low-level scheduling and resource allocation for real-time video tasks.
-
System Orchestration: Debugged and helped develop the full data path: Camera → Encoding FPGA → Transmitter MCU → Wi-R (EQS) Silicon → Receiver MCU → Decoding FPGA → AMOLED Display.
-
Signal Integrity & Debugging: Resolved critical timing and data encoding issues when interfacing with the display.
