Hello, I am PoChun (PC), a Ph.D. graduate from the Computer Science Information Engineering (CSIE) department at the National Taiwan University of Science and Technology (NTUST). My research area is video compression, focusing on H.264/HEVC.
My career began at HTC, where I worked on the video team handling tasks ranging from Android’s hardware abstraction layer (HAL) to firmware and kernel development.
At Catchplay, I developed video watermark algorithms and maintained the OTT transcoding system.
While at Realtek, I developed firmware for set-top boxes, focusing on H.264 and HEVC, and verified vendor IP in FPGA.
I then joined Apple Inc. as a Software Program Lead (SPL), primarily responsible for RunIn hardware tests, failure analysis, issue resolution, and cross-team communication.
After returning to Taiwan, I worked at ViewSonic, developing the ViewDirector product. I was responsible for various modules, including RTSP streaming, screen capture, window capture, webcam, and establishing a WebRTC video conference system, as well as pushing video streaming to YouTube and Facebook.
Currently, I am at Advantech, developing capture card products, assisting with DirectShow video and audio drivers, and ensuring drivers pass Microsoft WHQL certification.
I hope my experience can help you and your team achieve your goals.

Support the "View Director" base module, which includes RTSP streaming service, screen capture, window capture, webcam, WebRTC video conferencing, and pushing video streams to YouTube and Facebook.
The major task is to develop a set-up box, including:
1. Develop and maintain video firmware, such as H.264, HEVC and AVS2 firmware.
2. Verify IP in FPGA.
3. Bring up system.
1. Develop an algorithm to add watermarks to copyright content.
2. Decide on the bitrate for the set-top box.
3. Transcode video to HLS or DASH streaming format.
1. Fix integration issues between the hardware abstraction layer (HAL) and the kernel layer.
2. Verify that the video function meets Google's CTS/XTS requirements.
3. Port new patches.
