A NEW INTRAFRAME SOLUTION FOR HDTV TO SDTV DOWN-CONVERSION

In the last few years, high-definition television (HDTV) technology ha s been successfully demonstrated, and some products are available for video production. Since HDTV is being introduced gradually, standard d efinition television (SDTV) will coexist for a long time, therefore, s tandard converters are necessary to interface equipment and systems of different formats. In this paper a new solution is proposed for the c onversion of interlaced video signals from a high-resolution format do wn to a low-resolution format, having good performance, low implementa tion cost, and high design flexibility. Such flexibility can be furthe r exploited for an adaptive implementation.
