Hello, I am PoChun(PC), I am graduated in Ph.D. degree from CSIE of NTUST, my research topic is video compression (H.264/HEVC), during M.S. and Ph.D. periods, our team and me published four journal papers, I am the first author in one of them. During graduated school, ever used JM/HM reference software to implement paper's algorithm. My first job is in hTC company be a senior engineer, the tasks range in: HAL, Firmware, Kernel major tasks are : 1. fix integration issues. 2. porting new patches. 3. verify video functions can satisfy Google's CTS/XTS. My next job is in VATICS, major tasks are : 1. video algorithm development. 2. confirm the result between RTL and C-Model. 3. evaluation IPs. I ever had following experiences: 1. develop Finger Detection System without any mark at fingers. 2. fix the audio/video sync issue for streaming files. 3. use OpenGL ES to develop Radio, TPMS related GUI APP. 4. In Catchplay, developed watermark algorithm for video, and decide FirstMedia set-top box transcoder parameters. Then, I am a senior engineer in Realtek, the major task is develop firmware of set-up box, such as: 1. verify IP in FPGA 2. fixed firmware related issues. 3. bring up system My next job is Apple Inc.'s Software Program Lead, major duty is for RunIn part of hardware test, including failure analysis, push issue, cross team communication, also manage factory member to assist Runin test. My last job is in Viewsonic, Responding to RTSP streaming service, Screen Capture module, Window Capture module, Web Camera module, Try to establish WebRTC video conference system, push video streaming to YouTube and Facebook platforms. Hope above experiments can help you and your team have more ability to complete the missions.
