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). These systems have been developed such that they are 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. 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.
