Expertise includes work with high definition set-top box system and gateway. Leverage knowledge of C and C++ to develop tr69 protocol, video phone based on embedded Linux OS. * Developed network TR-069 proxy in Linux with C language. Successfully developed two-way communication protocol between two TR-069 clients (STB and cable modem sides) winning the Broadcom spot prize for design and efficient system performance. Implemented objects function in protocol TR181 for the network gateway management.* Developed specialized vlan for transmitting different types of packets from set-top box based on Linux OS to eRouter based on eCos OS. Implemented wan-to-lan data path through configurate snoops and bridges inside of router. * Coordinated successful startup and delivery of new BCM3390 chip. This chip includes two CPUs, docsis3.1 module, eRouter, WIFI, set-top box module, and more. * Troubleshooted, analyzed, and fixed issues for network gateway. Interfaced with customers and resolved issues mostly related to network packets lost, TR069, SNMP, snoop, firewall, insufficient download bandwidth, memory leak, system crash,etc. * Participated in video phone development. Specialized in video and audio encoding, decoding and optimizing overall system capability and stability. Optimize code structure to reduce the rate of network packet lost and time delay in data transportation.* Optimized state machine of video audio synchronization through PCR, PTS in transport stream. Expert in regards to video and audio sync both in video phone and set-top box. Successfully resolved many AV sync relevant issues for Cisco, Samsung, SumaVision project.* Developed hardware drivers for tuner and demodulator in set-top box platform. Familiar with I2C Driver and hardware modules debug. Good at oscilloscope for hardware debug.

Successfully developed some modules in set-top box middleware. The middleware is used to integrate different hardware platforms with one set of user interface module.* Developed the conditional access module and descramble module in middleware for set top box based on Linux operation system. Extract scrambled data from transmission stream and parse these data. Then inject scrambled data into hardware conditional access card to descramble it. Inject descrambled data into video decoder to enable decoding function. I also designed a set of APIs for this function in order to integrate different hardware CA card into this descramble module.* Took part in the development of a new state machine with notification registering and state flags to ensure faster, synchronous, seamless initiation of dozens of strongly coupled modules. Skillfully engineered this new fast boot up method with C++ language.* Conducted software development flow control, code maintenance and project development process, which are mostly with utilities like Clearcase, Accurave, CSP, and etcetera.
