This Recommendation defines error-correction@ data framing@ modulation and emission methods for the second generation of digital terrestrial television broadcasting transmission systems1 (referred to@ outside ITU-R@ as a DVB-T2 system which has been developed such that it is compatible with the provisions of the GE06 Agreement). This Recommendation is intended for the digital terrestrial broadcasting transmission system@ when high flexibility in the system configuration and broadcasting interactivity is of importance allowing for a wide-ranging trade-off between operation under minimal C/N levels or maximum transmission capacity2. 1 The second generation of digital terrestrial television broadcasting transmission systems in this Recommendation is meant as systems offering higher bit rate capacity per Hz and better power efficiency in comparison to the systems described in Recommendation ITU-R BT.1306@ and there is no general requirement for backward compatibility with first-generation systems. 2 For the first-generation systems information on planning parameters@ protection ratios@ etc. is already contained in relevant ITU-R Recommendations. For the second-generation systems@ there is a need to study and include such information in the relevant ITU-R Recommendations.
