Introduction

 

Cov khoom no yog ib yam tshiab ntawm video wireless video ntaus ntawv, using the latest COFDM modulation and MPEG-2 video compression technology is able to complete the video Transmission in high speed sports and NLOS (uas tsis yog-txoj kab ntawm pom) tej yam kev mob. The diversity reception technique greatly improves the quality of all reception condition.
