BBC research demos end to end DVB-T2

On the 60th birthday of BBC Kingswood Warren, engineers from BBC Research & Innovation succeeded in demonstrating a working real-time demodulator capable of receiving signals compliant to the DVB-T2 standard for the very first time.
Following the approval of the standard by the DVB on 26 June 2008 and then the successful test transmissions from Guildford on 27 June, the achievement – on Friday 29 August – is another significant milestone in the delivery of HD over Freeview.
The demonstration of DVB-T2 used a 36 Mbit/sec multiplex in a single 8 MHz channel. The multiplex contained three high definition programmes each coded at 11 Mbit/sec with the latest MPEG-4 encoders.
The demonstration was transmitted using a 256 QAM constellation with a 32k FFT, a 1/128 guard interval, and an FEC frame of 64800 bits code rate 3/5.
The system will also be demonstrated at IBC in Amsterdam later this month on the DVB stand 1.D81
