DVCPRO WIRELESS TRANSMISSION SYSTEM USING COFDM

摘要

A wireless digital video and/a audio transmission system is improved by using a DVCPRO compression/decompression scheme together with a COFDM modulation/demodulation. A disclosed example includes a wireless camera. The DVCPRO compression/decompression adds very little delay in the transmission chain and supplies a very reasonable video quality. The DVCPRO standard was introduced optimized and exploited only for recording on a tape. Here is is exploited for video and/or audio compression before transmission. The standard is simplified and only the steps till the error correction are performed. Further the COFDM is very robust for multi path transmission and does not result in picture quality loss as long as the maximal bit error rate is taken care of.
