The one week workshop was divided into two parts. The first part of the workshop covered basic theory on digital transmission starting from symbol, relationship between data rate and bandwidth, and different digital modulation schemes and their bandwidth requirements. The session also included modulation pattern, CFDM, COFDM, FEC, DVB-T2 frame structure, spectral and power efficiency in DVB-T2, frequency and network coverage planning for SFN and MFN, video compression and finally DTT challenges and opportunities.

The second part of the workshop was focused on the practical demonstration, where the participants were taken to the Rohde & Schwarz office near Kuala Lumpur.  The session started with the presentation done by Mr Chao Yin Loong, about the DVB-T2 transmission. After the session, participants were divided into two groups. The team was led by Mr Ganapathy from Rodhe & Schwarz.  A practical demonstration was done on the DVB-T2 transmitter. All the parameters discussed during the class were demonstrated onsite. Hands on training was also conducted for the participants where they visually tested the TV receivers with test transmitters.
