NEW Vehicle-mounted SD COFDM wireless video transmission system

NEW Vehicle-mounted SD COFDM wireless video transmission system

Product introduction:
ST6200CZA vehicle-mounted wireless image real time transmission system is broadcast-grade high definition real time transmission system. It adopts the current leading COFDM modulation technology. It has narrow air bandwidth (8 MHZ) and strong anti-multipath interference capability, combining with foreign advanced diversity reception technology, overcomes the perplex of multi-path reflection and shield caused by analog technology and conventional modulation techniques, to realize high-speed photography and real-time transmit high quality image in NLOS or complicated working environment. AV coding adopt MPEG-2 standard, definition reach to DVD resolution ratio(720*576@ PAL / 720*480@ NTSC). The advantage of the product includes clear image quality, good color performance and smooth image.
Product feature:
MPEG-2 standard high quality audio video NLOS wireless transmission; with real color rendition and comfortable perception. It is most suitable for economical project, meeting normal surveillance security & protection market(NLOS image real time transmission).

COFDM anti-electromagnetic interference performance:
It has superior performance against frequency selective fading or narrow bandwidth interference and signal waveform interference. It has strong anti-fading ability, through each sub-carrier joint coding.  In single carrier system(digital microwave, spread spectrum system, etc), single decline or interference will result in all communication link failure. But in multiple carrier COFDM system, only a few sub-carriers will be interfered What’s more, these sub-channels can adopt ECC to correct error, to guarantee the transmission low error rate.

COFDM anti-multipath fading performance:
It can confront signal waveform interference effectively., suitable for multi-path environment and fading channel high-speed data transmission. When the frequency selective fading appear in the channel because of multi-path transmission, only the sub-carrier, which fell over the band depression, and the information carried will be affected. Other sub-carriers will not be affected. Thus, the system total error rate performance will be much better.
