Study this: http://www.st.com/stonline/products/literature/bd/11219.pdf and pay particular attention to Figures 1-3. Remember that the "tuner" they show in the block diagrams comes in all-standards formats from several manufacturers. Also, do not forget that the Euro DVB-T implementation excludes HDTV, which is what causes almost all the differences. So compare the Chinese and US HDTV diagrams carefully.
