DVB To Demonstrate At BroadcastAsia

DVB has announced it will be showcasing DVB-T2, DVB-T2-Lite and DVB-GEM Based OTT Technologies at this year's BroadcastAsia show.
Three high definition channels and four mobile channels are being transmitted in one 8 MHz channel using DVB-T2 and DVB-T2-Lite.
T2-Lite is optimised for reception on mobile and portable devices.
Two Physical Layer Pipes (PLP) are employed for the different transmission types. In addition, FEF (Future Extension Frame), defined in DVB-T2 v1.3.1, allow the use of different FFT (Fast Fournier Transform) sizes and guard intervals.
The three HD channels, with content courtesy of the BBC, will be displayed on a Sony DVB-T2 iDTV and a T2-Lite mobile receiver. A DekTec DVB-T2 modulator will also be used in the demo.
The DVB stand includes presentations of DVB-T2 chipsets with set-top box demos from Broadcom and Altobeam. Information will be available on the latest ST Microelectronics’ System on Chip that features a T2 integrated demodulator in the form of an HDMI dongle.
There will also be a demonstration of an OTT transmission utilising a DVB-GEM based solution that features a set-top box using an Alticast implementation of DVB-GEM/MHP middleware.
Visitors can see a commercial hybrid service, using the most recent GEM 1.3 standard, which combines a local DVB-T stream and a live OTT stream coming from a live server in Italy.
The broadcast channel carries the relevant information for the broadband service. The user can switch between the DVB-T and the OTT service by simply changing the channel. The OTT content and portal is provided by Mediaset.
DVB-GEM is an open middleware specification, which enables the deployment of interactive applications over broadcast and broadband networks as well as for Blu-ray discs.
Version 1.3 of the Java-based GEM specification introduced an OTT device category that addresses media distribution over broadband networks with varying bandwidth such as the internet.
The official BroadcastAsia conference features a full day session delivered by DVB experts including DVB’s Executive Director, Peter Siebert and DVB’s representative in Asia, John Bigeni.
They will be joined by DVB Member representatives from Rohde & Schwarz, Media Broadcast, ENENSYS Technologies, Ericsson and TeamCast.
