For the purpose of this study, weimplemented a trustworthy videotransmissionsystemthrough turbocode. which has excellent errorcorrection ability. in order to restore data erroreffectively generated by noise when transmitting realtime data, security data, video data, etc. The imageprocessing system. NTSC (National Television systemCommittee) video signal from CCTV, and videocamera. etc. were converted from analog to digital(A/D conversion) transmission through a videodecoder. The converted digital image information wasoutput into two image fields. In this study, by applyingthe algorithm in which one field was selected of thetwo, we made a logic circuit of the ErasableProgrammable Logic Device (EPLD) and implementedthe system that reduces digitalvideo data by half. Inthe encoder/decoder system of the turbocode, theturbocode was implemented using the digital SignalProcessor (DSP) with which real number calculation ispossible. The interleaver part that affects theperformance of the turbocode was designed byapplying a block interleaver.
