ETRI: Cloud transmission for DTT

A great debate energising the IBC Conference this week is that of spectrum allocation as crunch time nears for the immovable object of broadcast and the irresistible force of the telcos. Korean researcher ETRI may just have found a way out of the impasse.

Its technology, developed for the next generation digital terrestrial broadcasting standard, enables the flexible use of broadcasting spectrum by providing robust mobile, portable and indoor receptions, as well as multiple HD and Ultra HD TV services. Novel spectrum overlay and signal cancellation technologies are used to combine the high data rate services. The system is claimed as robust against multipath distortion, noise and interference, and it described as scalable to transition to future developments.

The technology enables different content to be transmitted through a single channel for successful decoding on reception.
