MOTOROLA
(
Senior Test Engineer
·
Developed
and established performance standards for ADSL/VDSL set-top box (STB) systems
in the areas of RF and baseband video/audio signal
quality, digital picture quality, teletext and closed
captioning transcode functionality, and Sarnoff
MPEG-2 decoder compliance.
·
Designed,
developed, and automated test regime to verify STB hardware, firmware, and
software design to these established standards.
Researched and defined capital equipment requirements. Wrote plans/procedures. Executed tests. Documented results and defects. Provided support to design team in defect
debugging.
·
Spearheaded
significant improvements to video, audio, and ancillary data handling
performance of STB systems as a result of defects found.
·
Acquired
extensive knowledge and understanding of analog NTSC/PAL TV systems. Tested and evaluated STB video outputs in
formats such as composite, s-video, RF, component YprPb,
and component RGB. Extremely familiar
with applicable baseband video test standards such as
SMPTE 170M, ITU-R BT.470-6, EIA 250C, ITU-T J.61, SMPTE/EBU N10, and SMPTE/EBU
N20.
