Abstract: DVB-C stands for Digital Video Broadcasting-Cable. The standard was first published by the ETSI in 1994, and subsequently became the most widely used transmission system for digital cable television in Europe. The operation starts when video, audio, and data streams are multiplexed into MPEG-2 transport stream. The MPEG-TS is identified as a sequence of data packets, of fixed length (188 bytes). A first level of protection is then applied to the transmitted data, using a non-binary block code, a Reed-Solomon RS (204, 188) code, allowing the correction of up to a maximum of 8 wrong bytes for each 188-byte packet. Though there are many virtues of implementing DVB-C system, there are many shortcomings too of the same which cannot be neglected. The very first limitation and an important one too, is in the form of bit error rates supported by it. They are limited and not compatible with the existing and rapidly changing wireless standards. For the transmission of HDTV – high-definition television and also for accommodating more channels for broadcasting, there was a strong need of new standard. The second limitation of the DVB-C system is its hugely inferior performance with portability or mobility which restricted its usages in moving vehicles. To design a Digital Video Broadcasting – Cable System with MPEG-2 data as input. Analyze this system with different interleaving schemes (such as convolutional, block, random, helical and matrix interleaver), 64-QAM modulation and Reed-Solomon error detection and correction encoding for improving the efficiency of this system.
