Modulation and channel coding system for the distribution of digital multi-programme Television (TV)/High Definition Television (HDTV) by Multipoint Video Distribution Systems (MVDS) in the 40 GHz band. The System described in this ETS is based on that described in ETS 300 421 for 11/12 GHz satellite services. It allows the same consumer Integrated Receiver Decoder (IRD) to be used for either service, when used with a Low Noise Block (LNB) down-converter for the appropriate frequency band. The frequency band 40,5 to 42,5 GHz has been harmonised within CEPT under Recommendation T/R 52-01. The System however, is applicable to other frequency bands above 10 GHz. The System uses Quaternary Phase Shift Keying (QPSK) modulation and concatenated error protection strategy based on a convolutional code and shortened Reed-Solomon (RS) code. The System is suitable for use on different MVDS transmitter bandwidths. Compatibility with Moving Pictures Experts Group-2 (MPEG-2) coded TV services (see ISO/IEC IS 13818-1), with a transmission structure synchronous with the packet multiplex, is provided. Exploitation of the multiplex flexibility allows the use of the transmission capacity for a variety of TV service configurations, including sound and data services. All service components are Time Division Multiplexed (TDM) on a single digital carrier.
