TeamCast: Combined UHD/Mobile TX demo

A live demo showing Ultra HD and mobile TV transmitted over a single broadcast channel is on show at the TeamCast stand.

The experiment uses T2-Base for fixed reception and T2-Lite for mobile transmission to simultaneously provide HEVC encoded 4K TV pictures and an AVC encoded SD stream for mobile. These capabilities form part of the DVB-T2 standard and are being used on redundant Dual-Drive Twister Exciters with receivers from Sony.

Another live transmission demo on its stand is showcasing DVB-S2X compliant 64 APSK modulation with its recently upgraded Vyper satellite modulators.

New products at IBC include the Twister 4232, a dual mode PAL/DVB-T2 rack exciter designed for analogue to digital switchover, and the TWISTER-4000 system. The latter combines two Twister digital exciters and a RF switch unit to provide redundant operation for transmitters, in Dual-Drive mode.
