The Digital TV Group has selected four winners of its annual DTG Television Innovation Awards, which it hosted in partnership with UK Trade and Investment.

Chirp, CrowdEmotion, StreamHub and Grabyo fought off competition from four other companies during a Dragon’s Den-style contest to win a space on the DTG’s IBC exhibition stand.

DTG chief executive Richard Lindsay-Davies said: “The quality and diversity of this year’s entries shows us how much television technology innovation is coming out of, or scaling up, in the UK.”
